How to cheaply heat a house without gas? Alternative fuel for home heating without gas. Review of the most economical way to heat a house with electricity The cheapest autonomous heating

Owners of private houses choose heating with electricity for various reasons. Unfortunately, of all the existing methods, it is considered the most costly. Therefore, the question of how to reduce the cost of heating a house with electricity is more relevant than ever. We will consider the most economical way in more detail by comparing some types of heating systems.

Advantages and disadvantages of heating with electricity

Often, houses built on private plots are not connected to energy networks: gas, solid fuels. In such cases, the organization of heating with electricity becomes the only way out.

For example, many people install all kinds of heaters and stoves in the house if the main system is not yet working. Do such methods have obvious advantages and significant disadvantages? Let's take a closer look at this.

Heating private houses with electricity: undeniable advantages

Ease of installation of electrical heat sources.
The ability to quickly adjust the temperature to the desired level.
Saving energy consumption.
Mobility of heating sources (in the case of using mobile radiators).
Possibility to choose the type of convector for the interior of the house.
Environmental friendliness - oxygen is not removed (not burned) from the space of the room, there is no danger of harmful emissions.

Undeniable benefits

Cons of heating from the mains

The high cost of services for the provision of electricity.
If it is necessary to create a high voltage, the purchase and installation of an energy distributor will be required.

Advantages:

Such devices are compact.
Light in weight, affordable, but they have a high heating power. They can be grouped, included only one, or all at once.
And one of its main advantages is resistance to voltage surges, which is especially important for houses with old wiring.

But at the same time, the electrode system has disadvantages:

unstable power level;
extreme dependence on the composition of the conductive substance and its temperature;
requires strict adherence to the proportions of the solution and its purity;
incorrect "reaction" to regulation and automatic control.

User reviews about electrode boilers:

Sergey, Perm: Each heating season requires new electrodes, which is considered a very time consuming task. The manufacturer assures that if you adhere to all operational characteristics, the device will last a long time.

Natalia, Riga: Acquired the Vulcan-25 model. We are forced to disassemble and clean the boiler frequently. If the plates are not cleaned in a timely manner, the thermal conductivity decreases. The manufacturer recommends that first of all pay attention to the quality of the coolant.

Induction heating boilers

If the question arises of how to economically heat a house with electricity, then this is one of the best options. Today it is the most popular and technically advanced type of electric boiler.

It works like this: a primary winding is installed in the center of the apparatus, capable of passing an electric current, which provokes a voltage in the secondary winding section. It, in turn, consists of a pipe loop with a coolant. Due to the fact that there are no vulnerable nodes in such a device, the conductors of electricity do not come into contact with the heat-conducting carrier in any way.

An induction boiler can work stably for several decades! This is an economical device - with its help it is possible to reduce energy consumption by up to 40%, when compared with a heating element or electrode "brother".

Note! The device has only three conditional drawbacks - the noise from small vibration, the massiveness of the structure itself and its relatively high price.

Heating a house with electricity: the most economical way is infrared

Along with the boiler heating system, the infrared method is especially popular today. Special heating plates are installed in the house, in which the emitter draws in electricity and converts it into an infrared wave, and then transmits it. The waves from the heater are in continuous motion until they "collide" with some opaque object.

Plates are usually fixed to the ceiling or walls. However, it should be understood that it rarely acts as the main heating system for a large private house and is more often used as an addition.

Infrared waves quickly fill the room with heat, and then turn off automatically - this is possible thanks to a special independent automatic control system.

Note! This type of home heating with electricity is the most economical way, since it does not consume more electricity than is needed.

This option has only 2 disadvantages:

Expensive equipment (but at the same time it is energy efficient!).
Strict direction of heating from the plates to the nearest areas of the room.

Convector heaters

These heating devices are similar in function to conventional radiators - convectors heat up by themselves and transfer heat through the air. However, there is no coolant inside them, therefore, pipes are not required for them. Instead of a coolant, heating elements are built into the convectors (the advantages and disadvantages of this element were mentioned above), and cold air is taken through the bottom of the device.

One of the significant advantages of the equipment is its quiet operation, which is especially important for those who spend most of their time at home. But convectors also have a drawback - they are low efficiency. Electric convectors absorb a significant amount of electricity.

Warm floor

These electrical systems work on the basis of conductors with a resistor, through which an electric current passes, due to which they are heated.

The specified design components are too important. That is why the selection of all parts of the installation is important to carry out technically competently. The design of heating the apartment includes various devices. Heating installation includes batteries, air supply, expansion tank, fasteners, boiler pipes, pressure increasing pumps, thermostats, manifolds, connection system. On this page of the site, we will try to select certain parts of the system for your garage.

Choosing once favorable heating for your home outside the city, you can sleep peacefully like a baby, knowing that nothing will happen to your warmth. The heating network will work and heat your home the way you want it, no matter what the mood of the utilities is today.

Select the most profitable heating difficult, but possible. It is difficult for the simple reason that the assortment presented today is very wide. But the specialists of our engineering company "Savard" are always ready to come to your aid and help you find the best solution. Do not forget that only companies with the necessary licenses have the right to establish such communications.

The most profitable heating for private, country houses

By the way, profitable home heating can be installed even when you decide on the heating method. The point is that there are two methods. One of them - one-pipe - is suitable for small buildings. While for large or two-, three-story cottages, the two-pipe method is preferable, since it does not mix hot water and heat carrier.

The owners of private country cottages, who managed to install a heating system with water in their homes, unanimously claim that such heating is very comfortable. After all, the heating is excellent, the system is safe, the air is clean, dust-free and not dry.

The boiler acts as a heating element for the system. The boiler runs on natural gas or oil. Water enters the boiler using a special pump, which also supplies water to the batteries and radiators. It should be noted that the pump works almost silently, which, you see, is very convenient.

Which heating is beneficial and why?

After installing the heating system, it is necessary to carry out a pressure test. This requires a pressure test pump. There are different types of pumps. For a private house, manual is quite suitable.

Pressure testing is needed not only for pipes of heating systems, but also for sewer pipes. By the way, the sewerage scheme in a private house is simple. It is quite easy to build it. Read about the sewerage scheme in a private house in this article.

Characteristics of a heating boiler for a private house

The power of the heat generator is selected depending on the volume of the room. For a house with dimensions up to 400 m2, a boiler with a capacity of 42 kW is sufficient. For large area volumes, including guest houses, country panel houses. garages, saunas and greenhouses, a high-performance unit or an economical cascade system is required. It consists of several boilers connected to each other in turn. The thermal regime is supported by the automation, if necessary, turning on or off the units.

Fuel boilers are produced in two types: floor-standing and wall-mounted. Floor standing is more expensive, but more reliable and durable.

Types of double-circuit boilers, depending on power:

Flow-through type. They are used if the hot water consumption is minimal.
With integrated boiler. This system is designed for a full-fledged domestic hot water supply.
Specialized solutions: for heating water in the pool, arrangement of saunas and jacuzzi

In domestic boilers, an atmospheric burner is installed. The combustion products are discharged through the chimney, naturally or by means of a fan.

Steel
Galvanized
Stainless
Copper
Polymer

It is forbidden to gasify basements and basements
Ensure free access to the tank from all sides
Do not expose a container with gas to heat and direct exposure to sunlight.
Operation of tanks with damage to the body and corrosion is not allowed.
The distance from the cylinder to the boiler must be at least 1 m

For a continuous supply of fuel, it is best to install several cylinders. They are connected by means of a special ramp with flexible connection, a gas pressure measuring sensor and a safety valve. If the cylinder heats up, the valve will release excess gas, thereby reducing the pressure inside the cylinder.

The costs of home maintenance for private homeowners are already high enough. That is why the question is so popular, the cheaper it is to heat the house, the answer to which will save your budget.

Why is it profitable to self-heat the house?

To do this, you need to understand how the system works. So, there must be a boiler with the function of heating water, which then goes through the pipes and enters the heating radiators. After a while, the water cools down and goes back to the boiler, where it is heated again. This system works in a vicious circle. In some cases, you cannot do without a special pump when supplying liquid on a forced basis.

Many are interested in how it is more economical to heat a house with a water heating system, because it is known that heating equipment can operate on various energy sources. That is why the equipment is usually divided into:

Answering the question of how to economically heat a house, it is worth stopping at gas and solid fuel boilers, since the cost of "fuel" in this case is quite acceptable. Electric boilers can be quite expensive due to the cost of electricity.

Using heaters for heating

Modern space heaters are a very effective and safe method of heating rooms. Especially if they do not live in the house all the time, but several seasons a year. The most profitable option is considered to be the use of oil radiators, which store heat for a long time and consume a small amount of energy.

Thus, in order to determine which type of heating is best for you, you must first examine all the available options, weighing their advantages and disadvantages, the economic costs of installation and operation. Do not forget to choose the heating option based on the time spent in the country house. After all, if you live in the country only in the summer season, a fireplace and a stove will be enough, but if you live there in winter, you cannot do without a high-quality heating system.

The most economical way to heat a private house is an autonomous system that runs on natural gas. But often, for objective reasons, such an opportunity is not available everywhere. Solid fuel boilers or heating from a fireplace / stove with a closed firebox (if the house is small) are in the second place in terms of the cost of thermal energy, but if you take into account the need to store fuel and the complexity of maintenance, not everyone likes this method of heating. To store liquefied gas, expensive containers are needed. And liquid fuel, in addition to difficulties with storage, is distinguished by expensive equipment and poor environmental performance. Electric heating of a private house is devoid of all these disadvantages. Except for one thing - the high cost of the energy carrier. Although in this case, there are opportunities to reduce the burden on the family budget. What features does heating a house with electricity have? The most economical way that you can heat a house with energy, we will consider in our article.

Which heaters are not suitable for the heating system

Sometimes you have to read unfair criticism of some types of heating devices. They are criticized not for real shortcomings, but for fictional ones. Although at the end of the criticism, the conclusions are completely correct - these devices can only be used as auxiliary heaters, and it is impossible to build an economical heating system with their help.

Video description

In our video, we'll talk about heating in a private country house. Our guest is the author and presenter of the Teplo-Voda channel Vladimir Sukhorukov:

Oil radiator

Considered uneconomical - critics argue that it should not be used as a heating device due to its high energy consumption and low efficiency. But it is this type of device that has one of the highest efficiency - about 98%. That is, it converts almost all electrical energy into heat (the law of conservation of energy has not yet been canceled), and those insignificant losses of 2% are due to the resistance of the inner walls of the radiator to the coolant. Yes, it is inertial - it heats up for a long time, but also cools down for a long time.

Another drawback is that the room heats up for a long time with its help.

But this is a property of all batteries, including water heating, in which the main method of heat transfer is natural convection, and it flows slowly.

The main disadvantage is the "rough" power regulation and the use of mechanical thermostats. And such inaccurate temperature control makes the oil cooler ineffective when trying to optimize the cost of heating with electricity in a private house. Also, it has a rather high body temperature when operating at full power, which is dangerous if there are small children in the house.

There are models of oil radiators that can be hung on the wall Source b-sector.ru

Fan heater

A fan heater is often said to burn oxygen. But "burning oxygen" is nothing more than an oxidation (combustion) process, and the maximum that can burn out at a rather low temperature of the spiral is organic dust in the air. Therefore, it is incorrect to talk about burning oxygen (after all, the wood does not burn), since this insignificant volume must be replenished as a result of mandatory ventilation of the room.

The efficiency of such a device is slightly lower than that of an oil cooler (part of the electricity is spent on the operation of the fan), but not very different, given that the power of the fan motor itself is small (about 50 W out of a total of 1 or 2 kW). The advantage is that the room warms up very quickly. Disadvantages - constant noise level (albeit negligible) and dust transfer throughout the room. And the main drawback of these household appliances is manual power control and the ghostly possibility of creating an automated heating system based on fan heaters

The fan heater is the most compact heating device, and it is great for heating a small area.

Therefore, it is necessary to emphasize once again that the main reason due to which some types of electric heaters are not suitable for heating a house is not efficiency (almost all of them are above 95%), but the impossibility of automating the control of the system. It is this factor that does not allow optimizing the operation of the heating system, and without this it is impossible to heat a house with electricity cheaply.

Efficient methods of heating with electricity

Heating with electricity in a private house has the main advantages over all others - these are simple and accurate methods of monitoring and regulating the operation of all units and elements. Even the sensors and display of information about operating modes are more accurate than equipment based on other types of energy sources.

Individual electric heating of a private house has three options for heating systems:

autonomous hot water heating systems based on electric boilers:
use of infrared ceramic heaters;
electric convectors with electronic thermostats.

All these systems can be adapted into a smart home system and controlled remotely.

Heating by electric boiler

This is a classic scheme of an autonomous heating system. There are two options for heating the coolant - indirect and direct.

Electric boilers for indirect heating are of two types: heating elements and induction.

The device and principle of operation of heating elements are quite simple - there is a heating coil, enclosed in a sealed metal shell with a dielectric heat-conducting filler, heat from the spiral through the filler is transferred to the surface of the heating element shell, with which the heating system coolant contacts.

This is how the "filling" of a 9 kW heating element looks like, which, despite its compact size, is capable of heating a house with an area of 100 m2 Source mirvera.ru

Induction boilers have appeared for domestic heating systems relatively recently. Their principle of operation lies in the property of metals to heat up under the influence of an alternating magnetic field. The heating element itself is an inductive coil with a ferromagnetic alloy core, through the "secondary winding" of which the coolant passes.

Scheme of operation of an induction heater Source josri.ru

The peculiarity of electric boilers of direct heating is that water acts not only as a heat carrier, but is also part of an electrical circuit - an alternating current passes through it between the electrodes. Where does the name of the boilers come from - electrode.

Each type of boiler has its own disadvantages. The heating elements form scale, which leads to a decrease in the useful power and resource of the boiler. Induction - rather expensive, cumbersome and have a "step" power control. Electrode ones have severe restrictions on the quality and composition of water, which must have a certain specific electrical resistance to alternating current.

Well, the main disadvantage of heating a country house with an electric boiler is the presence of the coolant itself and a "bulky" circulation system from pipes and batteries. The arrangement of such a system is costly, and the efficiency in comparison with direct-action electric heaters can be less if circulation pumps are used.

Infrared heaters

There are several types of heaters that use radiation (radiation) as the transfer of thermal energy. This method of transmission is considered the most effective for heating a room - first, objects standing in the path of infrared radiation are heated, and then, due to secondary convection, the air is heated from them.

Video description

Clearly about infrared heaters in the video:

There are three principally different types of infrared heaters:

reflectors in which the incandescent spiral is enclosed in a quartz glass bulb;

panel - in a ceramic monolithic plate the heating element is "sealed";

film - with carbon spraying on a polymer film.

Heating a house with electricity of the first type refers to heaters operating in the shortwave range of infrared radiation.

Such devices can be used as an additional heater, but not as a basic element of a private house heating system with electricity.

Disadvantages - the lowest efficiency (due to the visible part of the radiation), lack of precise temperature control and high case temperature.

The second type of device operates in the soft long-wavelength range. The maximum temperature of the ceramic panel does not exceed 90 ° C, but on the case it is even lower. There are two types of control - mechanical and electronic thermostat. The first option assumes manual control and its accuracy is low. With electronic thermostats, you can set the temperature with an accuracy of 1 ° C.

The infrared panel is so safe that it can be hung on wooden walls Source centr-tepla.in.ua

Film heaters are the most efficient. Usually they are used as part of a warm floor, but in principle they can be mounted in walls or on the ceiling. But it is the installation as part of the floor covering that most of all corresponds to the correct and uniform heating of the room. The operation is controlled in automatic mode using the "temperature sensor-thermostat" pair.

If there is not enough space on the floor, then the film heater can be mounted on any free plane. Source otdelka-expert.ru

Convectors

Externally, the convectors are very similar to ceramic panel heaters, but inside the metal case there is an "open" heating element, enclosed inside a plate radiator. The fundamental difference in the heating method is that cold air enters the housing through the lower row of holes, in contact with the radiator, heats up and exits through the upper row of holes.

The convector body not only protects the heating element, but also increases the speed of the upward flow. Due to this, at the same power, the room is heated faster than from a hot water battery.

As with ceramic panel heaters, there are two types of thermostats - mechanical and electronic. And it is the electronic control of work that ensures the accuracy of the adjustment and the ability to work in several modes:

individual, manually controlled, used to heat a separate room;
group, the operation of several devices under the control of one (common) thermostat, which ensures uniform heating of a large area or the same heating mode for several rooms;
intelligent, control using a remote control, connecting to a GSM module and controlling using standard commands from a remote terminal (mobile communication, Internet), connecting to a router and controlling via a local network and / or the Internet.

What is better to choose: an electric boiler or an electric convector - clearly on the video:

An example of a real system with an intelligent control circuit for electric heating of a house

NOBO, a leading European manufacturer of convectors, produces two compatible intelligent control systems for electrical appliances. Including "warm floors" (through a thermostat) and any other household appliances that are connected to the network (through a shield, "break" in the circuit or turning on / off sockets). To do this, they produce special thermostats, receptacle receptacles and flush-mounted relay receivers.

With the help of such a system, it is possible to monitor and control the operation of up to 100 devices or group zones. And thermostats of the 700 series provide 4 modes of convector operation: comfortable, economical, non-freezing (air temperature 7 ° C) and "off". According to the manufacturer, the flexibility of such a control system for convectors and underfloor heating allows you to save up to 25% on electric heating at home.

As a result - how to optimize electric heating

In addition to the competent selection of heating equipment, an efficient and optimal (in terms of costs) heating system with electricity is possible only with a comprehensive insulation of the house - from the basement to the roof. Otherwise, the cost of heating a house that is blown out will be much higher, even despite the high efficiency of the heater itself, and heating the house with electricity is unlikely to work out cheaply.

At the present time, many owners of suburban private houses or summer cottages increasingly have to look for an alternative to gas as the main type of fuel to heat their homes. The reasons are different: for some, natural gas becomes too expensive a pleasure, someone has the opportunity to use other energy sources, and for someone the main gas is simply unavailable due to its complete absence nearby. Then the question arises - what kind of economical heating of a house without gas exists in general and what kind of fuel is better to use then?

Alternative energy sources

There is no unequivocal answer to this question, since each individual case has its own nuances. For example, a lot of old large trees grow on your plot of land, which just ask to be put into the firebox of a wood-fired boiler.

Option two: in return for certain services, the customer is ready to supply you with diesel fuel or coal for a long time. It is clear that in such situations you will lean towards these types of energy carriers and not pay attention to others. In the long term, this will be a mistake, since such sources will sooner or later run out and you will have to look for other ways to heat a country house or buy the same fuel, but at the generally accepted cost.

We will try to develop some kind of universal method for determining the optimal energy carrier for heating a home, which is suitable for each individual case. First, we will make a reservation that the methodology will help to determine the cheapest heating without gas, we do not take it into account.

Just as we do not take into account various high-tech and exotic types of heating, inaccessible to ordinary citizens. This includes heat pumps, solar panels, wind turbines, and various types of machine and vegetable oils. Then how to heat the house if there is no gas and the above sources? We have at our disposal:

ordinary firewood;
eurowood;
pellets;
coal;
diesel fuel;
liquefied gas in cylinders;
electricity.

For each of these energy carriers, a calculation of the costs for the entire cold period should be made, then it will be clear what the cheaper it is to heat the house.

Important! Before starting the calculations, it is imperative to bring the units of measurement of the amount of fuel into conformity, that is, to avoid confusion between volume (m3) and mass (kg). It is recommended that all types of energy carriers, except for electricity, be reduced to units of mass - kilograms.

Calculating heating costs

To find out what is the most economical heating of a country house, it is recommended for clarity to draw up a simple plate of this form:

In this table, the second column is filled in based on the cost of each type of fuel in your region, or your individual price is entered into it. The third column is already filled in for convenience of calculations. The cost of 1 kW of thermal energy can be easily determined by dividing the price of 1 kg of fuel (column 2) by its specific calorific value (column 3).

The fifth column is filled on the assumption that the average heat consumption in a private house with an area of 100 m2 per season is 5 kW / h, and the duration of the heating season is 180 days (5 x 24 x 180 = 21,600 kW / h).

It is clear that house designs are all different and the area will be different, just as the length of the season in your region may differ, so you will need to make the appropriate adjustments. Multiplying the data in columns 4 and 5, we determine the estimated costs for the season.

However, these values do not take into account the efficiency of the equipment, the values of which are given below. Dividing the estimated costs by the efficiency, in the last column we get a direct answer to the question - the cheaper it is to heat a house except for gas.

For homeowners who already have gas boilers installed, another row can be added below for comparison, populating it with natural gas data based on actual fuel consumption and price.

It would seem that now everything has fallen into place and you can safely make a choice in favor of one or another energy carrier for economical heating. But this approach is one-sided, because there is also such a thing as convenience and complexity in the maintenance and operation of the heating system of a private house.

Choosing an energy carrier taking into account ease of use

The comfort of operation of boiler equipment that supplies heat to water heating is an important factor, since any unnecessary troubles and inconveniences are your time and money. That is, the total cost increases indirectly according to how much effort is put into keeping the system running. In some cases, economical heating systems after the first season no longer seem so economical and sometimes you want to pay extra money, just not to get involved with such problems.

In contrast to financial indicators, ease of use - the value for each type of fuel is unchanged, so it can be found out immediately, which will help to make the right choice. Convenience will be assessed by the following criteria:

the complexity of the repair or maintenance of the boiler plant;
necessity and convenience of storage;
comfort in daily use (the need to load fuel, and so on).

In order to find out which of the energy carriers will provide comfortable and economical heating of a private house, we will draw up a second table, where for each of the criteria we will put down ratings for all types of fuel according to a five-point system, after which we will summarize.

Service

Electric boilers do not require any maintenance, except for sometimes opening the lid and dusting off or cleaning the contacts, for which they receive the highest marks. Some actions are required if you heat a country house with liquefied gas. It is recommended to check and, if necessary, clean the igniter and burner once every 2 years, because propane is a solid four. Pellet boilers receive 3 points for the fact that they require cleaning the combustion chamber several times a year and once the chimney.

Accordingly, wood and coal units need to be cleaned frequently as they become dirty. The worst situation in this respect is the situation with diesel fuel, since its quality often leaves much to be desired, which is why the frequency of service is unpredictable.

Warehousing

It is clear that electricity does not require storage space, while LPG and diesel fuel may require some storage space. But when economical heating of a private house with wood is organized, then a lot of storage space will be required. The same applies to pellets, as they require a dry room or special silo. As for coal, there is a lot of waste, dust and dirt from it, therefore - the lowest rating.

Ease of use

And here economical electric heating turned out to be at its best, since it does not require any intervention during operation. Pellets and liquefied gas must be replenished periodically, 1-2 times a week, or even less often. A little more attention should be paid to diesel fuel, more for supervising work than for adding fuel.

Well, most of all the trouble is traditionally delivered by autonomous heating in a private house on coal and wood, here the load into the combustion chamber is needed from 1 to 3 times a day.

In the last column, by summing up, the results are summed up, according to which the most comfortable and convenient is heating a country house in winter with the help of electricity. If this result is considered in conjunction with financial costs, then electricity may not be the worst option.

Conclusion

An integrated approach to the issue shows that the most economical heating systems for summer cottages and country houses can be the most troublesome during operation. Therefore, you should not rush and carefully weigh and calculate everything, or even better - install an electric boiler in combination with any other.

Heating a private house requires a certain amount of money - consumers need to regularly pay for the energy used. Therefore, the question of the efficiency of heating systems worries many. How to make the most economical heating of a private house with your own hands? Which heating boiler to choose? To do this, you need to figure out what a particular heating system is and what its potential is in terms of ensuring efficiency.

Autonomous heating systems are traditionally used to heat private houses. The sources of energy for their work are natural gas, liquefied gas, solid fuels, liquid fuels and electricity. The most economical systems are considered to be fueled by natural gas.... But in some conditions, their efficiency does not play any role. For example, if the house is not connected to the gas main, then comparisons with gas are not relevant here.

Gas heating systems

Economical heating systems for a private house are systems that operate on a cheap heat carrier. If a gas main passes nearby, we feel free to connect to it and use one of the most inexpensive energy sources. Comparing the cost of gas with the cost of other sources, you begin to realize that this is one of the most inexpensive types of fuel.

Solid fuel heating systems

Economical heating of a private house without gas can be built on the basis of a solid fuel boiler. Coal, coke, briquetted fuel and even ordinary firewood are used to feed it. Coal burns the longest, but it is also quite expensive. But the heating system turns out to be not only economical, but also inexpensive - the simplest solid fuel boiler is quite affordable.

The cheapest heating of a private house without gas is built using solid fuel boilers, sometimes homemade. If you want to ensure more convenient operation of the system, you should take a closer look at the boiler with a small bunker for pellet fuel (fuel pellets). Such pellet boilers operate in automatic mode, requiring only periodic loading of new portions of pellets.

The work of solid fuel boilers on wood is complicated by the need for too frequent loading of wood. In addition, a lot of firewood is needed, which increases the cost of operating the heating system. One has only to miss the moment of loading the next portion of fuel, as the house begins to become cooler. The problem is solved by installing special long-burning solid fuel boilers.

Liquid heating systems

Heating systems on liquid fuel cannot be called the most economical. After gas and solid fuels, they occupy an honorable third place. Waste engine oil and diesel fuel are used here as fuel. Because of this, there is a constant smell in houses heated by liquid boilers. There is also a need to create a special storage facility for liquid fuel, moreover, at a distance from residential buildings - this creates additional costs.

Electric heating systems

It is difficult to create cheap heating of a private house with electricity - you need a source of free electricity. The thing is that classic electric boilers are unusually voracious... And it is almost impossible to do something here, since their efficiency is 99% - that is, almost all energy is converted into heat. Induction boilers can provide some efficiency, but many experts are not ready to confirm this fact.

Economical electric boilers for heating a private house exist, but they are much more expensive than their simple small-sized counterparts. Achievement of savings in them is carried out through the use of weather-dependent automation and room temperature sensors. That is, they are able to automatically adapt to the peculiarities of outdoor and room temperature conditions, adjusting the heating power - if a person was involved in the adjustments, then the costs would be higher.

How to make economical heating in a private house

How to make cheap heating of a private house with your own hands? For this you need:

Use the most economical and efficient heating boiler;
Pay attention to the thermal insulation of your home;
Use alternative heat sources.

The principle of operation of a condensing boiler, one of the most profitable devices for heating a private house.

If there is gas in the house, take a closer look at the condensing boilers - they have high efficiency and almost completely transfer heat from the burner to the heating system. If you want to create the cheapest heating of a private house without gas, think about purchasing a solid fuel boiler - by buying a truck of firewood, you will provide yourself with relatively cheap heat for the entire cold period. Also you need to pay attention to the installation of radiators with high heat dissipation.

Thin entrance doors, lack of proper thermal insulation of walls, old windows - all this contributes to heat leakage outside your home. We recommend that you install normal entrance doors with effective thermal insulation, order plastic windows and think about lining the house with a layer of brick (it is also possible to apply a cement "jacket" that creates good thermal insulation) - this will reduce heat loss and reduce heating costs.

Alternative heat sources

As for alternative heat sources, they can be:

Infrared film for creating warm floors;
Solar panels;
Heat pumps.

A heating scheme in which heat is generated using electricity obtained from solar panels.

Solar panels use the free energy of the sun - they generate electricity that can be used to heat the coolant or to operate other heating equipment. Their disadvantage is the very high cost.- you need to spend a lot of money to buy the required number of batteries.

Heat pumps use energy from water bodies, soil or air. Their principle of operation is based on taking heat from the environment and transferring it to heated rooms. If you do not delve into the laws of physics, then the principle of the refrigerator is used here. To power the heat pumps, external sources of electricity are needed, but even taking this into account, the heating system turns out to be quite economical. But the cost of heat pumps so far negates their advantages.

If you need to create an economical heating system for a private house without gas, you can use infrared film. It runs on electricity and warms up the floors - under the influence of infrared radiation, they heat up and begin to give off heat to the premises. According to experts, the film provides up to 30% efficiency in comparison with the use of conventional electric boilers.

Heat bills won't scare you anymore! What is the most economical way to heat a house?

Heating is the largest energy consumption in most homes. It accounts for from 35 to 50% annual electricity bills.

The most effective way to reduce the size of these bills is to reduce your heating energy use.

The heating system replaces the heat that is lost through the walls, windows, floor and ceiling of your home.

Methods for economical heating of a private house

The amount of energy required to replace the lost heat, depends on four factors:

the location of the house (in colder regions, the consumption is higher);
the size of the building;
energy efficiency at home;
energy efficiency of the heating system.

The first factor is the main but he is not dependent on you. The colder the weather outside, the more energy it takes to maintain a comfortable temperature inside.

Important and the size of the house. A spacious room contains a significant amount of air that needs to be heated. Therefore, a large house requires high heating costs.

A great opportunity to save energy and money is to improve the energy efficiency of your home and its heating system. There are several ways to do this:

choose the optimal type of heating system;
improve the insulation of the facade;
repair the heat distribution system (ducts and pipes);
eliminate heat leaks through doors, windows and various crevices.

How to insulate the facade

Thermal insulation of the facade in the form of its insulation is the main protection of the house from heat loss through the building body. Therefore, it is very important to insulate the largest part of the house in terms of area - the walls of the facade. Insulating materials reduce heat loss by providing a barrier between the inside of the house and significantly different outside temperatures.

Houses use different types of insulation. The most common ones- polyurethane foam, expanded polystyrene and fiberglass.

Polyurethane foam

Foam insulation is spray or injection foam.

Spray foam in a liquid state, it is distributed in the open spaces of the new construction of the house. After that, the foam expands, fills the cavity and hardens.
Injection foam pumped into existing cracks, crevices or other voids in walls. This makes this polyurethane foam indispensable for repairing insulation in existing homes.

Expanded polystyrene

Styrofoam happens with open or closed cells.

Open cell expanded polystyrene very lightweight and flexible. When the polystyrene foam is foamed, the gas inside the cells exits through the holes in the cell wall. This process helps create a lightweight and flexible shape that hardens as it hardens.
Closed cell expanded polystyrene has a much denser and heavier structure. It forms a dense surface that is more resistant to weathering and temperature changes.

Fiberglass

Fiberglass is made from soda, limestone, sand and crushed glass and is supplied in slabs or rolls. It is placed in unfinished walls, floors and ceilings between pins, beams and beams. Due to its fibrous structure, such material is excellent keeps air inside and prevents heat loss.

Efficient boilers for space heating

In order to efficiently and economically heat a house, it is necessary to choose high quality heating equipment... Most often, boilers are used in this role.

Condensing gas

Boiler operation with condensing gas allows you to use all the energy released during gas combustion. All boiler systems distribute heat to hot water, which gives off heat by passing through radiators or other devices in rooms throughout the home. The chilled water is then returned to the boiler for reheating.

In a conventional boiler, the heating circuit is heated by the combustion of natural gas. Condensing boiler uses the energy available in the products of gas combustion... These products contain water vapor. Steam, cooling down, condenses and gives off heat. The water in the heating circuit is heated by this energy. The evacuation of water released during condensation (condensation) is carried out through the wastewater network.

Important! Natural gas is the most readily available energy source. Therefore, the operating cost of the condensing boiler will be the most profitable.

Such a boiler is easy to operate, consumes less fuel than a standard gas boiler, and has an efficiency, often exceeding 100%.

Pyrolysis

The pyrolysis boiler runs on solid fuels. In this case, not only the firewood itself burns, but also the gases that are released in the process.

Therefore, the efficiency of such boilers is up to 90%. Firewood or special pellets made from dried biomass burn in one chamber, releasing pyrolysis gas.

Under the influence of high temperature, the gas through a special nozzle enters another chamber, in which it burns, mixing with oxygen.

The heat energy released in this process much higher than in conventional boilers and the burning time is much longer. Therefore, pyrolysis boilers are called long burning boilers.

Such gas-generating boilers do not depend on the presence of a main gas pipeline, and can be most efficiently use purchased fuel.

Solid fuel

The simplest boiler is a wood or coal fired boiler. He completely autonomous, and does not require any connection to a gas pipeline or electrical network, nor the cost of paying for gas and electricity. It is enough just a standard body, consisting of a firebox (or combustion chamber) and a blower, and ordinary firewood.

Firewood is burning in the firebox thanks to the air that is supplied through the blower. This releases heat energy. It heats up a steel or cast iron coil-shaped heat exchanger located in the firebox and raises the temperature of the coolant. Hot water gives off heat when it passes through the home's heating system. The chilled water is then returned to the boiler for reheating.

Electric boiler

Electric boiler operation is similar to the work of other boilers: the water heats up in it, and then circulates in the heating system circuit and radiators.

Heating of water in such boilers occurs using electric current... It provides high performance and excellent heating rate.

In addition, the installation of an electric boiler does not require large expenses for the installation of expensive equipment, the presence of a chimney and a large room.

Warm floor

Underfloor heating is the most old form of central heating... Even the Romans used an underfloor heating system that warmed buildings and baths. Today's underfloor heating system is gaining more and more popularity in Russia.

Underfloor heating is a system that heats a house through a heated floor covering. Exists two types of such a system... In the first type warm water heats the floor through the underfloor piping (wet system). In the second, the floor becomes warm with electric coils placed under it ("dry" system).

The concrete floor slabs heat up and heat radiates from under the floor into the room. "Wet" system can be connected to a gas boiler to heat water... This will help to significantly save on cheap gas fuel.

Attention! For this type of heating large-scale construction work is required. Therefore, its installation is best done during the construction of a house.

Infrared heating is one of the most economical ways

The infrared spectrum is part of the electromagnetic spectrum. This form of radiated heat is the most basic. This is the same 100% natural heat type that radiates and absorbs the human body on a daily basis.

Photo 2. Installation of infrared heaters under the roof of the house, this installation method allows you to completely warm up the room.

The peculiarity of infrared radiation is that it heats objects and people in its path. without heating the surrounding space... This makes infrared heating much more efficient than convection... Convective heat generated by conventional radiators and central heating systems only heats the air.

Warm air is distributed around the room, circulating uncontrollably, and leaves objects in the room cool. Infrared heating emits direct heat and heats everything up. This type of heating brings long-lasting, comfortable warmth to the home, consuming less energy.

Infrared heaters can provide directed heat anywhere, regardless of distance... This means that there is no need to spend electricity on heating any room, even the largest area, and heat is not lost due to air circulation.

Solar collectors - cheap and economical

Solar collectors use the warmth of sunlight to heat water, which is then sent to the inside of the building. They consist of a panel of heat-absorbing material into which it is pumped mixture of water and antifreeze to collect heat. This mixture then heats up the water in the hot water system, so solar collectors must be integrated into the existing heat distribution system.

Photo 3. Solar collectors installed on the roof of the house. Devices must be placed at a specific angle.

Such heating systems can be useful not only in warm climates. Even a small increase in water temperature dramatically reduces the amount of energy required to heat it. Solar collectors create favorable conditions for starting any heating systems. It means that less energy is used in general.

How to heat a house with heat pumps in winter and summer

Heat pumps are devices for transferring warm air using an electric pump. In winter, warm air is separated from the cold in the open air and spreads inside the house. In summer, the heat pump changes its direction of flow and the warm air from the room is blown out. Heat pumps use forced air systems to circulate heated air throughout the home.

Exists two types heat pumps.

Geothermal

Ground source pumps pump warm air from a pipeline located underground... The temperature in such a source stable year-round.

In geothermal pumps, the collector circuit is a coil buried in long, shallow pits or in vertical wells.

The efficiency of heat pumps is often sometimes more than 100% because they use electricity not to create heat, but to move it.

Air

Air Source Heat Pumps use the outside air as a heat source in winter and as a heat sink in summer. These heat pumps look and fit the same as an AHU.

Conclusion

Heating our homes is expensive and gets more expensive every year. As costs rise, each of us is looking for more affordable heating and insulation options. Fortunately, there are many such options... Choose carefully combine different types and heating systems and you will be able to choose the option that is optimal in terms of price and efficiency.

What method of heating the house will be the most economical

Heating a house can be organized in different ways, but which one is the most economical method available? We will try to figure this out below.

Selection of heating method - nuances

To determine what kind of option is the most economical way in your case, you should accurately answer a number of questions. The list is as follows:

For example, for houses in which the owners are visiting, it is impractical to use permanent heating.

Fuel

The very first thing is to find out what kind of fuel in your area is most affordable. The main criteria are as follows:

uninterrupted supply;
resource cost.

It is the availability of an energy carrier in a given area that is the main starting point.

In most cases, they are used in private houses:

natural gas;
firewood;
coal (both hard and brown);
fuel oil;
peat briquettes.

Sometimes they also heat with electricity - this is far from one of the most economical methods, but in the absence of an alternative, this possibility must be taken into account.

Depending on the list of available resources, the boiler is also selected. The calorific value of this appliance directly affects the overall efficiency of the entire system.

The weakest of all the above property is in systems operating on solid fuels. This is followed by:

But, as statistics show, today, on average in Russia (if all the described energy carriers are available in any locality without exception), then natural gas is necessarily the cheapest.

The least economical heating is undoubtedly electric. Other ways to do without gas, although much cheaper, will still require twice as much as the cost of natural gas. However, in the absence of an alternative, there is not much to choose.

Depending on what kind of resource is available in your region, the choice of the heating system is also made. There are 2 types most commonly used in Russia:

Electricity

If we are talking about electricity, then here the proven ways to heat a house are:

warm floor;
infrared panels (film heaters, etc.);
convectors;
boilers.

The first three types are suitable for relatively economical heating of buildings where people do not live permanently. Their consumption is far from small, but a few days of use per month is not critical. For wooden capital country houses, the most convenient are, probably, film heaters. They consume only 40 watts per square meter.

The advantages of electric heating are:

low cost of installation;
ease of maintenance;
fine adjustment;
noiselessness.

Water heating

Such systems work the same regardless of the type of boiler installed in the house:

the carrier, heated to operating temperature, is fed into the pipes;
circulates through all radiators (the latter, due to convection of air masses, provide heat transfer);
cooled water returns in a closed loop back to the boiler.

At the same time, one of the most economical is heating with natural circulation. Since pumps for pumping the coolant are not installed in the system, it means that there is no need to spend additional electricity.

At the same time, if the house has an area of more than 100 square meters, the described option will not work. A large length of communications leads to an increase in hydrodynamic resistance in the pipes, which means that the movement of water will be too slow.

The disadvantages of hot water heating are:

the boiler must work constantly;
adjusting the exact temperature in each room is almost impossible.

Air heating

Compared to the above methods, the considered one is quite economical. It is ideal both for houses where people always live, and for those in which they are visiting.

The principle of this system is simple:

the air is heated directly through the air heater;
is fed into the premises through special sleeves and grilles installed either in the floor or in the wall.

The undoubted advantage can be called:

literally lightning-fast heating of the whole house;
economical use of fuel;
high efficiency (about 90 percent);
low maintenance costs of air ducts.

noise occurs during operation;
installation of the heater requires, according to safety rules, a rather large room.

List of other methods

It will be useful for the thrifty homeowner to find out what to reduce costs, and quite significantly, insulation will allow. A high-quality thermally insulated house consumes much less resources (about half) while maintaining comfortable conditions for its inhabitants.

Such work must be carried out in a comprehensive manner:

walls are covered with foam or pressed mineral wool;
windows are installed with double-glazed windows;
the attic floor and floors are necessarily insulated.

Installing a programmable heat regulator will also allow more efficient use of energy for heating. This device:

can independently monitor the temperature in different rooms;
turn off the heating in the absence of people;
controlled remotely through the built-in SIM card.

Heating a house with electricity: the most economical way and advantages of choice

It is known that the gas system is considered the most inexpensive heating option. But there are situations when it is not possible to use it, for example, if the gas main does not pass nearby. In this case, heating the house with electricity is recommended. The most economical way can be found by analyzing all the options offered. This is what we will do in this review.

This option is suitable for buildings outside the city and country houses

Why you should choose heating your home with electricity: the most economical way

Electric heating system has the following advantages:

Electricity-based appliances are virtually silent and do not require an additional type of fuel. They do not pollute the atmosphere. To use them, you only need an electrical network;
installation of equipment does not require significant investments;
to save energy, you can use a two-rate meter system or a solar panel on the roof;
the connection of the convector or boiler can be done independently.

Heating by electricity is carried out using different devices

Electric heating options for a private house

Such a heating scheme involves the use of various types of equipment.

Boiler application

It is not uncommon to install an electric boiler for heating a 220v house. Such a device belongs to the budget options and is easy to install.

Electric boilers are of the following types:

TEN models belong to the traditional options. The heating element is heated by electricity and transfers heat to the coolant, which transfers it to the installed radiators. This unit is equipped with a thermostat that allows you to keep the temperature at a certain level. The disadvantages include scale that collects on the heating element;

The diagram shows the principle of operation with heating elements

in the electrode type of the boiler, instead of the heating element, there is an electrode that acts on free ions, which creates heat. This is a safe design option, since if water leaks, the device stops working. With this method of heating, limescale does not occur, but only water can be used as a heat carrier;

Electrode model device

the device of an induction electric boiler includes a pipeline and a radiator. In this case, the radiation mechanism forms an electromagnetic field that interacts with metal elements. Electricity produces vortex currents that transfer energy to the coolant. Such a product is characterized by ease of installation and maintenance. Water, oil compounds or antifreeze are used as heating fluid.

Installing an induction device

Selecting IR Panels

When deciding how to economically heat a house with electricity, you can consider the option of installing infrared structures. Such products do not warm the air inside the rooms, but various objects. If in the version with a boiler the air masses move upwards and then cool down, then in this case the hot streams are directed to the floor.

Infrared designs do not take up much space

If you add thermostats to IR devices, then they will work more efficiently. One regulator is enough to control three heaters. This equipment is economical to use, but expensive in terms of installation and construction costs. Infrared devices consume a small amount of electricity. They also distribute heat efficiently. They can be used for spot and zone heating. Even after the structure is turned off, objects generate heat for a long time.

Infrared panel device

Installation of such equipment can be done independently. The infrared system is used both as the main type of fuel and as an additional one. The advantages of this option include a long service life, up to 80 years.

Heating the house with electricity is also carried out using an infrared underfloor heating. It is an economical and effective remedy. This design is not afraid of unexpected power surges and does not break with minor damage. Such a device can be installed under various flooring except parquet. Infrared rays heat only solid objects, therefore, when the floor is heated, the elements themselves do not heat up.

Infrared ceiling panels

Convectors advantages

When choosing the most economical electric heating without a boiler, it is worth examining the possibilities of convectors. According to the manufacturers, the convector, powered by the mains, heats the space with high quality and at the same time spends a small amount of electricity. The main advantage of the device is that its installation is simple.

It takes about two minutes to warm up the heating element, which is much faster than when heating with water devices. The advantages of such designs include:

low cost of equipment;
fire safety;
the heating system can be completed not immediately, purchasing additional radiators as needed;
modern design;
uninterrupted operation even with sudden voltage changes;
small size.

This method maintains the desired humidity ratio in the room and does not destroy oxygen at the same time. Excellent technical properties and excellent power indicators allow the use of electric convectors for heating both large and small private houses.

Such designs are compact and portable.

The main element of the design is the heating element, which converts electricity into heat energy. The principle of operation is air convection. In this case, the cooled flows penetrate into the slots of the lower part of the housing and then exit through the upper openings. The convector can be operated separately or in a system controlled by a temperature controller.

Wall-mounted models are characterized by functionality and allow you to free up space

Which option is better not to choose?

When choosing the most economical way to heat your home, it is worth exploring options that are not worth buying. The costly options include an oil cooler. It has increased power, but it consumes a lot of electricity when working in winter. Despite the significant power, such products have a low heating efficiency. Interestingly, infrared panels of the same power will warm up the space in the house faster. Fan heaters are ineffective devices. They reduce oxygen, make noise and move dust.

Oil heater can be combined well with other heating methods

How to improve the efficiency of electric boilers for heating a private house: prices and methods

To get the most economical way, heating the house with electricity must be properly organized. The efficiency of the entire structure can be reduced as a result of poor thermal insulation. Various gaps, cracks and a lack of insulation on the windows contribute to the rapid cooling of rooms.

If no one is at home during the whole day, then you do not have to heat the house for the whole day. In such a situation, you can install a special controller that will start the heating system a few hours before the arrival of residents. Two hours is enough to fully warm up the rooms.

Electrical equipment operation diagram

Of great importance is a skillfully drafted heating system, taking into account the location of the heaters and the power. Installation of a multi-tariff meter is considered a good solution. This device allows you to save electricity at night, when the heater is in operation.

Helpful information! With good insulation of the ceiling and walls, the quality of heating can increase up to 80%.

To get a home heating system with electricity cheaply, you need to choose the right equipment and calculate the location of all appliances.
