Rating of the most economical gas boilers for heating a private house: how to choose? How to buy the most economical boiler for heating a country house The most economical gas heating boiler.

Heating a house is one of the basic tasks of life support.

Unlike European residential buildings, where the operating conditions of the heating system are lighter, in Russia it is necessary to have a powerful and efficient heating circuit.

Since the capabilities of the system are determined by the characteristics of the boiler, working in difficult and harsh conditions requires a special approach to the development and production of heating technology.

Most domestic manufacturers follow this path, considering first of all reliability and resistance to external loads.

Let's take a closer look at this issue.

Russian manufacturers produce an almost complete list of gas heating boiler designs. In their arsenal there are many varieties and options.

By feature set:

• single-circuit... Designed only for heating the coolant and supplying it to the heating system;
• double-circuit. In parallel with performing the basic function, these units are capable of preparing hot water for domestic needs.

By installation method:

• wall. They are installed in a hinged way on strong (load-bearing) walls or special structures - ramps. The specificity of installation requires boilers to be limited in weight and dimensions, therefore, the power of wall-mounted boilers is relatively low;
• floor. They are installed directly on the floor, so there is no weight limit. This allows the use of powerful and massive units, details. The power of the floor units is the highest. In addition, they can be connected in a cascade, obtaining total indicators close to those of serious thermal power plants.

By type of combustion chamber (burner):

• atmospheric, or open... Air intake is carried out directly from the room, and smoke is removed naturally, through a traditional type chimney;
• turbocharged, or closed... For combustion, air is supplied with a special fan. Overpressure builds up in the combustion chamber, forcing the smoke out through the horizontal coaxial chimney. Fresh air passes through the outer pipe into the boiler, and combustion products are removed from the boiler through the inner pipe.

By way of power supply:

• volatile. As a rule, these are boilers, which are more or less exact copies of European models. They need to be connected to the power supply to work;
• non-volatile. They work exclusively on a mechanical principle, which makes them the most preferable in conditions of unstable power supply. The disadvantages are the use of natural draft and circulation of the coolant, which does not allow the development of a given power. However, these problems are easily solved by connecting external devices, and the ability to ensure continuous operation in all conditions remains.

Parapet boilers are also manufactured by Russian manufacturers. They are able to heat rooms without a radiator system, spreading heat energy by convection.

Such structures are convenient for heating apartments and other premises of a relatively small area..

NOTE!

The most popular and promising are non-volatile floor standing boilers. They have high power, are able to provide basic functions (heating and hot water supply), do not have unnecessary components. This makes the units reliable and resistant to any external influences.

Russian brands

Floor standing gas boilers are one of the main directions in the work of all Russian manufacturers.

Consider some of them:

• Conord. The head office is located in Rostov-on-Don. Floor-standing gas boilers are available in single and double-circuit versions. A total of 4 series with a capacity from 8 to 30 kW are offered, the difference between which is in the number of circuits and the type of automation;
• Signal. The plant is located in Engels, Saratov region. Currently, two series of floor-standing non-volatile boilers are being manufactured - S-Term and Comfort. The power of the boilers ranges from 7 to 150 kW, which allows you to choose the right model for any premises and conditions. There are one- and two-circuit models;
• Siberia. Products of the company LLC "Rostovgazoapparat". This is a group of non-volatile floor-standing units, presented in three series - Economy, Comfort and Premium. The power range is from 11 to 50 kW. There are single and double-circuit models;
• ZhMZ. These are gas boilers manufactured by the Zhukovsky Machine-Building Plant. The range includes single and double-circuit models of non-volatile floor-standing units with a capacity of 11 to 68 kW. They are produced in three series - Economy, Universal and Comfort, differing from each other in the type of automation and the shape of the case;
• Lemax. Manufactured in Taganrog. The plant's products are wall and floor models with one or two circuits. Three series are produced - Premium, Premier and Prime. The power of the units ranges from 10 to 35 kW.

Most of the boilers are non-volatile, which is determined by difficult working conditions, dilapidated power supply networks or a complete lack of connection in remote villages.

This approach is quite justified - in cold weather, a sudden power outage will immediately stop the heating system, and if the power supply is not restored in a matter of minutes, defrosting of the pipelines is inevitable.

The only solution would be an emergency drainage of the coolant, but this measure is not always possible.

Therefore, the presence of heating boilers independent of external conditions is a very useful solution for the domestic user.

Why is Lemax the best brand based on user reviews?

• a wide variety of design options, functionality and parameters;
• low fuel consumption. In combination with high efficiency, this allows you to get great cost savings and increase the resource of the boiler;
• the ratio of price and quality of Lemax boilers is considered the most successful;
• the durability and reliability of the units are highly appreciated by both specialists and ordinary users.

Due to these features, Lemax boilers are usually classified as the leaders of domestic heating technology. However, one should not assume that all other products of Russian manufacturers are significantly inferior to these units.

From the point of view of design and performance, the developments of domestic engineers are approximately at the same level. The main advantage is getting rid of redundant supplements that few people use.

The fewer unnecessary units and parts, the more reliable the design and the easier its repair.... This applies equally to all units made in Russia. Lemax boilers are presented in a larger assortment, but not so superior to alternative options.

The prices and capabilities of domestic floor-standing gas boilers are at the same level, which makes the products of domestic manufacturers available and in demand.

Each of us wants to install heating equipment that will work not only efficiently, but also economically. Are there economical gas boilers? Depends on what you mean by this. A list of models with minimum fuel consumption could be given, but everything is relative here, and many factors affect the cost of maintenance. Let's take a look at each of them.

The most economical heating boilers

How to reduce gas consumption in the heating system? First of all, you need to choose a device that is right for your home. Why is that? Because only taking into account the area of ​​the room, the material of the walls, the number of windows and other factors, it is possible to calculate the required power and performance of the boiler. Only then will the technology effectively give off heat without wasting extra energy.

If you want to save on gas consumption, then connect only to a common line. It is very expensive to use cylinders. What criteria affect savings:

• Design features;
• Coefficient of performance (COP);
• Power of technology;
• Fuel quality;
• Optimal mode.

Let's go over each item in more detail.

Engineering design

Heating boilers are available with one and two circuits. A single-circuit device is designed only for heating the room, and for hot water supply (DHW), you will have to additionally connect a boiler. But the double-circuit models already include everything you need for heating a house and for hot water supply.

To calculate the savings, look at the type of combustion chamber. An open chamber draws air from the room to maintain combustion and evacuate gases. The closed one forcibly drives the air from the street. The combustion products are removed by a fan. This principle contributes to the complete combustion of the fuel, as well as the minimum emission of CO2.

Closed appliances are connected to a coaxial chimney. Its tube-in-tube design traps more heat. Therefore, the air from the outside is heated, which increases the combustion efficiency.

Effect of efficiency

Today the market offers the buyer also condensing boilers. Which is more economical? It is considered to be condensing because it uses the energy of condensate. Taking into account additional energy, a conventional unit has an efficiency of 92-94%, and a condensing unit has an efficiency of 100-102%.

The standard job is to burn the fuel and vent hot gases outside. Combustion products contain impurities and moisture. Passing through the heat exchanger, the gases reach 60 °. Because of this, sediment falls out and accumulates in the tank. In the process, energy is released, which is used by the condensation device. It is believed that this can save up to 20% in fuel. But here, too, there are some pitfalls. Such units are installed to low-temperature systems with underfloor heating.

There are also a number of other nuances that we described in the article "".

What affects the efficiency of a convection boiler:

• Physical underburn. When air burns out instead of gas. Fuel quality affects;
• Chemical underburning. Depends on the amount of carbon monoxide in the combustion process;
• Poor insulation, wall insulation.

How to set up for optimal performance:

• Clean the system at least once a year. Remove limescale from the heat exchanger, soot from the burner and pipes;
• Place a damper on the pipe to restrict air flow;
• Clean off soot from combustion chamber parts, otherwise gas consumption will increase.

Equipment power

The power of wall-hung and floor-standing boilers is different. Hanging heats rooms up to 300 m². But the floor ones can heat huge areas. The optimum temperature of the coolant depends on the power. Why is this indicator important?

There is such a concept - boiler clock. This is the frequency of turning on and off heating depending on the temperature drop. An overly powerful device will not be able to work in optimal mode - the manufacturer takes this into account, indicating the efficiency of the model. The appliance will turn on frequently and the rest interval will be short.

On the contrary, weak equipment will quickly wear out, since its work will go to the limit of possibilities. Before buying, pay attention to the optimal power - this is 75% of the maximum performance.

How to economically set up a technique

We examined the main factors that affect the degree of fuel consumption. How to choose the right boiler and use it so as not to overpay the bills?

Power calculation

What factors are taken into account:

• Room dimensions;
• Wall materials, the presence of insulation;
• Additional heating radiators;
• Number of windows;
• Climatic zone.

It is best to entrust the calculation to a specialist. In the future, thanks to this, you will be able to save on operating costs.

Technical condition

Carry out technical inspection and breakdown prevention in a timely manner. Install a water filter to reduce salt build-up. When the water is heated, limescale deposits in the tubes of the heat exchanger. It interferes with heat transfer, so that the device starts to consume more gas. Therefore, you should periodically clean the radiator from deposits.

Also remove dust and grime from taps and parts.

Gas quality

You cannot influence this factor as well as the pressure drops in the line. But you can choose equipment with maximum adaptation to Russian conditions. Then it will work stably even with pressure drops.

Optimal mode

What temperature should I set? You yourself choose the temperature for normal boiler operation. For example, you set the value to 55 degrees, which means that the unit will constantly work at that temperature. But the weather outside the window in winter changes: it becomes colder and warmer. It is understandable that this makes the room temperature less comfortable. How to fix this and even save money? Let's reveal the trick: you need to install an automation system.

In new models, it is already built-in, and if yours does not, it is not a problem to buy it. This includes control sensors and an external thermostat. The latter measures the temperature in the house, due to which the mode is regulated. The technique will adequately respond to temperature changes, consume less resources.

Another saving secret: set a lower temperature for the night.

To all of the above, we will add good insulation of walls and windows: this will give + 20% of energy resources to the piggy bank.

Brand and manufacturer

Remember, we wrote that the efficiency of the technique is relative? This is true. But still, foreign models are more economical in terms of efficiency: "", "",. The documentation of Russian and foreign manufacturers may indicate the same percentage of efficiency. But we know that the same Germans approach the assembly of equipment more carefully and scrupulously. On the other hand, do not forget that most of the foreign models are assembled in China or here in Russia.

Conclusion: the most economical boiler is properly selected in terms of power, efficiency, and build quality. During operation, this is influenced by maintenance, prevention of breakdowns, the established mode. We hope our article will help you make the right choice and "legally" reduce gas consumption.

Since gas in Russia costs an order of magnitude lower than electricity, many owners of private houses turn to the installation of gas boilers. However, economic parameters are far from the only advantage of units of this type over others - they include high thermal power, optimal level of efficiency, minimum amount of harmful emissions, as well as the possibility of heating large premises (on average, from 150 to 300 square meters).

Of course, like any other technique, gas boilers have disadvantages. These include the strict coordination of the installation with the federal service of Gaztekhnadzor, equipping the house with a chimney to remove (a small amount) of combustion products, as well as the introduction of automation to detect gas leaks.

In our rating you will find 15 of the best and highest quality gas boilers, the purchase of which will provide you with warmth and hot water for many years. Before that, we advise you to study some of the nuances of choosing a gas boiler for a house or apartment.

The right choice - double-circuit or single-circuit?

As you know, according to the number of circuits, gas boilers are usually divided into single-circuit and double-circuit. Which one is better? The correct choice depends on the main purpose of the device.

Single-circuit ones are designed exclusively for the operation of the main coolant (radiators, pipes, etc.), that is, they are bought to provide heating. Most often, such devices are installed in summer cottages and in places where there is no water supply. In this case, a boiler is purchased for a single-circuit boiler to heat water in an autonomous water supply system.

Double-circuit boilers are 2 in 1 devices. They can both heat the house and provide hot water supply. The coolant and the boiler in such a device are collected in one unit. If hot water is not consumed, the heating medium circulates in the heating circuit. As soon as the user opens the hot water tap, the system switches the valves so that the heat carrier is directed to the second circuit. This is the most popular type of gas boilers, which are installed in most apartments and private houses.

Heated power

The more powerful the boiler is, the higher its cost. In order not to overpay extra money and eliminate additional costs in the future (the more powerful the boiler, the more it consumes resources), it is important to calculate what kind of gas boiler you need in terms of power. An approximate calculation is as follows: for 10 sq. m. of a well-insulated room (ceiling height up to 3 m) should account for 1 kW of the boiler's thermal power. For a poorly insulated room, another 30-50% is added to the heat output.

For a country house of 50 sq. m. it is enough to purchase a gas boiler with a capacity of 7 - 12 kW. But for a house with an area of ​​200 sq. m. you will need a more powerful device: 23 - 25 kW. Most modern double-circuit gas boilers are produced with a thermal power of 24 kW.

There is one more important detail when choosing the boiler power. If you take a device that is too powerful for a small room (for example, a 24 kW boiler for a one-room apartment of 40 sq. M.), Then the boiler will quickly heat up the coolant and turn off. As soon as the water cools down, the boiler will start up again. Constant switching on and off will occur very often, which will lead to accelerated wear and increased gas consumption. In turn, a boiler with a lower power will provide a smooth combustion, and on-off will occur much less frequently.

Which company to give preference to?

The highest quality and most reliable gas boilers are manufactured by Italian, German and South Korean companies. Even taking into account the fact that many companies locate their production facilities in China, purchasing a gas boiler of a popular brand is better than buying a little-known device.

To facilitate your choice, we list the list of the best manufacturers of gas boilers:

• Navien (South Korea)
• Bosch (Germany)
• Ariston (Italy)
• Baxi (Italy)
• Buderus (Germany)
• Vaillant (Germany)
• Protherm (Slovakia)
• Viessmann (Germany)
• Kiturami (South Korea)

Voltage stabilizer for a gas boiler - is it necessary or not?

After purchasing a gas boiler, it is advisable to install a voltage stabilizer. Especially if your network suffers from frequent power surges. The fact is that in the event of a boiler failure due to a power surge, it will not be possible to exchange the device under warranty. The requirement for the quality of the network is spelled out in each warranty agreement. Therefore, it is better to spend an extra 3-5 thousand rubles for a device with a capacity of up to 1 kW (and a powerful stabilizer for the boiler is not needed) than to end up losing tens of thousands of rubles.

Best inexpensive wall mounted gas boilers

The main advantages of wall-mounted gas boilers are lower price and compactness in placement. They are more preferable for areas with limited space. For example, for an apartment. The disadvantages of wall-mounted models are lower power and shorter service life, in contrast to floor-standing devices.

3 Navien DELUXE 24K

Best ergonomics at an affordable price
Country: South Korea
Average price: 29 800 rubles.
Rating (2019): 4.5

Gas boiler Navien DELUXE 24K is maximum comfort at minimum cost. A double-circuit heat energy generator is used for sequential heating of premises with a total area of ​​up to 240 sq. M and for meeting domestic and household needs in hot water with a capacity of up to 13.8 l / min at t 35 ° C. A distinctive feature of the heater in the material of the primary heat exchanger is stainless steel. This fact slightly reduces the efficiency of the unit to 90.5%, but prolongs its durability due to the reliability of high-alloy steel.

Comfortable use of the hot water installation is ensured by a convenient display and clarity of instrumentation, an adapted room regulator with a remote control panel. The ease with which operative intervention is carried out in the cyclicity of the boiler operation can significantly reduce the consumption of blue fuel during operation.

The reviews note the stable operation of the electronic circuit under conditions of periodic voltage fluctuations in the supply network, amounting to +/- 30% of 230 V. The uninterrupted functionality is due to the presence of the SMPS (Switched-Mode Power Supply) protective chip, which complements the microprocessor. The combustion process in a closed chamber takes place without harmful interruptions and stops, which has a positive effect on the service life of the equipment, excluding breakdowns.

2 Baxi MAIN 5 24 F

Best quality
Country: Italy
Average price: 37 820 rubles.
Rating (2019): 4.5

The gas boiler Baxi MAIN 5 24 F is an example of a double-circuit unit in the line of biothermal heating devices. The engineering and technical solution, which combined the heating circuit with the preparation of water for hot water supply in a single hydrosystem, made it possible to significantly reduce the cost of a wall-mounted unit in comparison with heat generators equipped with separate heat exchangers. At the same time, there was no significant decrease in performance indicators. The boiler has enough capacity to heat an area of ​​240 square meters and prepare 9.8 l / min hot water at t 35 ° C.

The heat generator is designed to operate on natural and liquefied gas with a wide range of pressure in the fuel pipelines. When connected to centralized gasification mains, the coverage ranges from 13 to 20 mbar. A high pressure threshold of 37 mbar is allowed when powered by mobile and stationary gas tanks. This indicator indicates the high reliability of the boiler fuel equipment.

Customer reviews emphasize that the most popular options for a gas unit are the ability to connect external control: room regulators, weekly programmers and the provided interface with low-temperature heating circuits (underfloor heating).

1 Vaillant turboTEC pro VUW 242 / 5-3

High efficiency with maximum reliability
Country: Germany
Average price: 53,700 rubles.
Rating (2019): 4.5

The leading line of the rating is occupied by not the cheapest in the category, but the most reliable and efficient gas boiler Vaillant turboTEC pro VUW 242 / 5-3. The craftsmanship of German manufacturers knows no bounds: for more than ten years of production, this model has heard mainly laudatory reviews regarding various aspects of the design and operation.

A double-circuit boiler can be used not only as a heater: when a cold water source is connected to it, it copes no less brilliantly with the functions of a boiler. The maximum temperature of the DHW circuit is 65 degrees Celsius, which is more than optimal for home use. 24 kW of power is enough for heating residential areas up to 240 square meters. In this mode, Vaillant turboTEC pro VUW 242 / 5-3 shows the highest efficiency value - about 91%. It is also worth noting the presence of six levels of protection, electronic control with the ability to modulate the flame, as well as a six-liter (generally standard) expansion tank.

The main disadvantages of the model affect the purely marketing side of the manufacturing company. The cost of servicing Vaillant boilers is very high, and the owner will bear the costs both for the purchase of a branded part and for its subsequent installation (approximately 50 to 50). Fortunately, serious breakdowns of units are extremely rare.

The best floor-standing gas boilers from the budget category

Floor standing gas boilers are considered more reliable and durable. They cost more than wall-mounted models, but they gain in power and can heat rooms from 200 sq. m. For the installation of floor-standing boilers, it is recommended to use a separate room (boiler room).

3 Protherm Wolf 16 KSO

The best automation. Developed service network
Country: Slovakia
Average price: 21,200 rubles.
Rating (2019): 4.5

The non-volatile "floor stand" presented by the Slovak company "Proterm" is surprisingly small in size. At only 39 cm wide, almost 75 cm high and 46 cm deep, it can be easily installed in any small room. In the "Wolf" series, 2 modifications are presented, differing only in thermal power of 12.5 and 16 kW, sufficient for heating a private house with an area of ​​30 to 150 sq. m.

The fact that the main production site of Protherm is located at the Vaillant plant, the world-famous German manufacturer of gas boilers, will tell a lot about the quality of workmanship. Floor-standing units are made of steel 3 mm thick, equipped with temperature and emergency controllers, a draft stabilizer, and a SIT gas burner device (Italy). The design is easy to install and operate, and therefore does not cause complaints from users. However, it must be taken into account that the 2-year warranty for the unit applies if installed by a certified specialist.

2 ATON Atmo 30E

The most powerful gas boiler (30 kW)
Country Ukraine
Average price: 27 800 rubles.
Rating (2019): 4.0

A powerful single-circuit boiler of Ukrainian origin, which has everything you need to ensure stable heating of premises up to 300 square meters. Actually, ATON Atmo 30E fulfills its main task beyond praise - the absence of a second circuit for heating water allowed Ukrainian craftsmen to pay more attention and funds to improve and fine-tune the heating function.

For normal operation, the boiler requires 3.3 cubic meters of gas per hour. This is quite a lot (especially for a budget model), however, almost all the energy from the combustion of fossil fuel (the unit efficiency is 90%) is converted into thermal energy, which, in combination with 30 kW of power, results in such a vast heated area.

In general, the presence of the principle of economy is felt in the model: the designer cut off almost all "civilized" functions, leaving only the most necessary for the boiler - a thermometer, gas control and a thermostat to protect against overheating. This step has led to a noticeable increase in the level of reliability, since fewer components lead to fewer possible (elementary) failures. In general, ATON Atmo 30E is an ideal boiler for a large country house, not burdened with additional functions and the need to work as a boiler.

1 Lemax Premium-25B

The largest heating area at an affordable price
Country Russia
Average price: 27 360 rubles.
Rating (2019): 4.5

Lemax Premium-25B is an inexpensive floor-standing convection-type gas boiler. Produced in Taganrog. Able to efficiently heat a house up to 250 sq. m. with an efficiency of 90%. The low cost of the device is due to the steel structure of the heat exchanger. Such material is more susceptible to corrosion than copper and cast iron heat exchangers. However, the developer has provided a special heat-insulating coating with inhibitors, which should significantly reduce the corrosion of the heat exchanger.

The boiler is equipped with everything necessary for the safe operation of the system: heat exchanger overheating sensor, thermometer, gas control. There is auto ignition - ignition is carried out automatically. This indicates a higher reliability and efficiency in comparison with piezo-ignited devices. The nominal pressure of natural gas is 13 mbar, that is, the boiler will operate at full capacity even at low pressure indicators in the gas network (which is not uncommon in Russia). This is the best indicator in our review of budget floor standing boilers.

It is worth noting that the Lemax boiler is designed for an open heating system, therefore, when buying it, a chimney must be provided in the house for the removal of combustion products.

Most of the user reviews speak of Lemax's "indestructibility" and almost silent operation. It is an economical and hassle-free boiler at an affordable price, with a 3-year manufacturer's warranty. One of the best deals in the budget segment.

The "Logano" line includes 4 standard sizes (from 20 to 32 kW) of low-temperature boilers, which are considered more profitable and safer in comparison with high-temperature boilers. In addition, low temperatures in the heating system create the most comfortable conditions for a person, while excluding strong temperature drops in an apartment or a private cottage. The unit can be built into the heating system using underfloor heating, and if the heat loss at home is too high, it is possible to supplement it with radiators.

Additional heat savings are facilitated by the special design of the cast-iron heat exchanger and thermal insulation 80 mm thick. In order for buyers to individually assemble the heating device, the company offers an extensive selection of additional parts and assemblies, which, I must say, are very expensive. For example, the AW 50.2-Kombi flue gas control system is offered to be bought for almost 9.5 thousand rubles, and at least 50 thousand rubles will have to be paid for the Logalux SU floor-standing water heater. Nevertheless, consumers are satisfied with the economy, ease of operation and durability of the model and recommend it for purchase.

The best wall-mounted gas boilers of the condensing principle of operation

During the operation of the gas boiler, condensate forms, which can be used to generate heat energy. This is exactly what happens in boilers of the condensing principle of operation, where additional energy from condensate is generated using a special heat exchanger (economizer). This will undoubtedly increase the efficiency of the device.

Installing a condensing boiler allows you to save up to 20% on gas bills. Thus, the efficiency of a conventional convection boiler is on average 92%, while a condensing boiler is capable of operating with an efficiency of 109%. True, the purchase of a condensing model will be much more expensive than a convection model and, perhaps, such a decision will be justified when heating sufficient areas.

Recently, there have been new items of gas boilers called condensing boilers. In their technical characteristics, you can find some incomprehensible figures - "efficiency 109% !!!". It turns out that according to the calculation methods, which do not take into account the so-called latent heat during combustion, 109 - 111% of the heat of normal combustion is actually obtained. With this play on words and numbers, sellers attract the attention of the buyer.

But the efficiency of the boiler depends not only on its efficiency. Condensing may not be a priority, as it is expensive in itself. Ultimately, the efficiency of a boiler is how much money was spent on heating a home.

Is it possible to reduce heating costs and how to do it - this is the main question that worries residents.

Let's take a closer look at which gas boiler will be economical, how to make heating cheaper with it.

We save on buying a boiler

Condensing boilers, like hot cakes next to cold ones, are exhibited at a price almost 2 times higher than that of conventional gas boilers of the same power.

But while there are disputes as to why the price is high, let's pay attention to what condensing boilers give in the end. They have an increased efficiency - 109 percent, compared to conventional wall-mounted gas boilers with a closed combustion chamber, which have 92 - 94%. But also, according to manufacturers, fuel savings with a condensing boiler can reach as much as 20%.

Due to what achievements

Condensing boilers must operate with a low coolant temperature - up to 50 - 60 degrees. Then they develop their "monstrous" efficiency, due to the additional energy released during the condensation of water vapor in the exhaust gases (the resulting liquid is discharged into the sewer).

But the nuance is that low-temperature heating is more economical in itself - less hot air rises uselessly to the ceiling.

It is especially advisable to use such boilers with water underfloor heating - a particularly economical low-temperature heating system that distributes heat in the area where a person is located.

Those. the main savings lie not in the design of the condensing boiler, but in the idea of ​​low-temperature heating, in the system with which this boiler is intended to work.

Output

It turns out that while the heating system in the house is not converted to a low temperature (simply, the power of low and long radiators should be 30-40 percent more) and while there are no heated water floors, then it seems that it is not worth throwing out a lot of money for this boiler ...

But it must be borne in mind that with a conventional heating system in most medium-insulated houses, such a boiler will mainly operate in condensation mode during the season. How long will the fuel savings cover the difference in the price of boilers - you need to calculate in each specific case.

The general trend is also important - almost all of Europe is already "sitting" on such boilers and the laws there have adopted the obligation to use this technology for heating, which is also more environmentally friendly.

Design features affecting efficiency

All gas boilers are fundamentally different in the main combustion chamber - whether it is closed or open. Now only powerful floor standing boilers are produced with an open chamber.

The natural draft of the high chimney is used for purging, and air is taken from the room. Wall-mounted boilers are made with a closed chamber running under a fan, and air is taken from the street through a coaxial chimney (pipe in pipe). In this case, the supplied air has time to heat up.

In general, a closed combustion chamber of conventional boilers provides greater efficiency, more complete combustion of fuel in a smooth operating mode. Boilers equipped with such a chamber are more efficient and economical. This is a well-known fact, and of course the preference is for devices with a closed chamber.

For a gas boiler, power selection is important

Manufacturers recommend the optimal operating mode of their equipment - the supply temperature and the return temperature are such and such, combustion is mostly continuous. Then the boiler works with normal efficiency, less unnecessary dew and soot are formed.

But if the owners purchased too powerful a boiler, then it will not be economical at all. It will often turn on and off, its power will not be in demand, and a significant percentage of the time it will work in transient non-optimal modes (in the camera warming up mode - with dew and soot).

The gas boiler must be selected for the optimal power so that it works in a given mode. Then the boiler will be economical.

Experts recommend choosing a boiler 20 - 30% more than the maximum heat loss in the house. Then the equipment will not go out of operation, but its power will generally be enough for unforeseen cooling by a draft, and even for heating water with the same circuit in the boiler.

We create an economical mode of operation

Let us ask ourselves a question - is it not in vain that sometimes the boiler heats the air for us? Maybe in some cases, you can reduce the temperature. Those. program the boiler so that it burns a little less fuel, but this would not affect the comfort in the house.

And there are two reserves here:

• night mode - a lower temperature of the coolant or air in the room is simply set, depending on what the boiler is oriented;
• a system of reaction to weather changes is created - an external temperature sensor and a programmer are installed (if the boiler is not equipped with this). It also helps to reduce the number of starts when it gets warmer outside.

Already these measures allow to save 10-15% of the flared gas.

Disconnecting rooms from heating

But the big savings are hidden in point disconnection of rooms where to maintain
heat is not necessary.

In most houses there are rooms in which you can not heat at least the whole winter or at a certain time of the day.

They will help to save thermal heads on pressure valves installed on the supply to each radiator. Now you can set the air temperature at which the radiator should turn off.

And electronic thermal heads allow you to program the process in time. Such a system allows you to save on average 20% on heating, and in some cases all 50%. But thermal heads can only be used with an automated boiler, so that overheating does not occur at certain points of the system.

The manufacturer is important

Do not forget that the very status of the manufacturer also speaks volumes. If we are considering the products of a well-known European, Japanese, or Korean concern, then the declared characteristics of the boilers, their durability and verified operating modes can be trusted.

If, for no reason at all, we purchased the products of an unknown gray manufacturer, then we should not be surprised to find that something is wrong, including with the fuel economy.

The boiler is a solid device for long-term use, and you need to approach its purchase seriously.

Which boiler will be more economical

Thus, the most economical boiler will be the following:

• from a well-known manufacturer of the middle price category;
• wall-mounted with a closed combustion chamber;
• optimal power, 20 - 40 percent more than heat loss (depending on the need to heat water for hot water supply);
• connected in accordance with all the rules of hydraulics, as well as using the programming of operating modes and thermal heads on the radiators.

But if a water floor heating has already been debugged in the house, and low-temperature radiator heating would also be nice for it, then we need to talk about buying a condensate economical boiler.

The most important nuance

True, there is one nuance that has not yet been talked about, and which can, in one fell swoop, cancel out all the savings percentages that we are trying to scrape together with different methods in one fell swoop.

It is not even necessary to talk about the efficiency of the boiler itself and the heating system if the building is not insulated. In an uninsulated house, the bill for heating money increases significantly.

Those. in a cold house, you will need a heating system 2-3 times more powerful in order to compensate for heat losses and develop an acceptable temperature inside. Another way out is to freeze.

Only after insulating the building, no less than required by SNIP 23-02-2003, it makes sense to start talking about the efficiency of the equipment itself and consider condensing options ...
