For those who have a cottage or Vacation home, the prerogative to create a steam room for yourself and for guests is very tempting. Provided that there are no problems with the voltage in the network and on the site, you can do it and thereby save money.

Note! If you decide to buy a ready-made electric fireplace, choose it based on the temperature regime, electricity consumption and heating power.

Why Choose Electricity?

Nowadays, it is really easier to build an electric heater than to heat a stove with wood. Because it:

Clean - no ash on the floor near the firebox and blew, getting your hands dirty to kindle the fireplace is also not necessary;
Fast - start and heat up the oven, this process does not take much time;
Safe - the likelihood of getting burned is minimized. There is also no risk of gas leakage, explosion, the likelihood of a fire is significantly reduced;
Convenient - with the help of a modern control panel, set any set parameters will not be difficult;

What is true, you will only have to put up with the high costs of electricity, so if you are ready for them, move on.

What do you need to manually assemble the oven?

Gathered to create do-it-yourself electric sauna stove- it is necessary to select a thermal heating element (TEN). It is also worth deciding what type of oven will be, open or closed. Usually the second option is chosen more often, since the heating element in it can be installed in any position. In addition to the heater, you will need a screen and a bus for the voltage wire.

Assembly of the electric heater

When starting work with electricity, it is necessary to familiarize yourself with the construction and technical instructions in detail, check the equipment and use a protective suit. When assembling do-it-yourself electric baths be sure to observe grounding, and also at the first start, check the resistance so that it falls in the range of 3-5 ohms.

What to make the case from and what size it should be, you decide, based on the volume of the room that needs to be heated. Usually sheet steel is chosen, the heater can be made open lattice or closed. Installation of equipment from pre-purchased or welded elements occurs as follows:

First, the number of heating elements is determined, based on the cubic capacity of the bath room;
The heating elements are connected to each other using a system of jumpers;
A heat shield is equipped from sheet steel;
The heater is welded and laid out.

Tip: it is better to choose river stones, flat ones - they are in ready-made sold in hardware stores.

A frame is assembled from metal sheets. The electric furnace can also be laid out with bricks.
An electrical circuit is assembled in series and a control relay is installed. Rotary switches are usually chosen.

Done, the oven can be connected to the network and after checking all the indicators, enjoy the new steam room for quick heating.

For a bath or sauna, large brick ovens, which provide heating not only for water, but also for stones. But such models are too massive, they require a special base, complex maintenance, safety measures, since open fire is used for heating. Yes, and the cost of such stoves is significant, and for masonry it is recommended to invite a stove-maker. But for a bath with your own hands, you can assemble a small but efficient electric stove, which is great not only for an ordinary Russian bath, but also for a Finnish sauna, where so-called dry heating is needed.

The advantages of an electric furnace: fast heating, easy maintenance, very easy to regulate and operate.

Types of sauna stoves

For a sauna with your own hands, you can make almost any type of stove that will provide comfortable conditions.

The following types are popular:

Do-it-yourself brick oven for a bath is quite massive construction which requires installation separate foundation, and the scheme of its masonry must be carried out exactly, according to the order. Red is used for work. kiln brick firewood as fuel. The stove is heat-intensive, but heats up slowly, requires a chimney to remove combustion products, and ventilation is also necessary to supply fresh air.
A metal wood-burning stove is lighter than a traditional brick stove, it is made of sheet steel, dry firewood is used as fuel. The weight of this structure is less, a special foundation is not required, but a pedestal, a protective wall is needed.
The electric oven is now considered the most suitable for small saunas or baths. This is a compact device that actually consists of heating element and containers for stones, water. This design is easy to do with your own hands, it is practical, it is easy to use. For such a furnace, there is no need to install a chimney. The sauna will turn out with such a unit comfortable and convenient.

Advantages of an electric furnace

Vertical oven.

By choosing an electric sauna heater, you get whole list advantages:

Fast heating while maintaining a predetermined comfortable temperature throughout the entire period of use, which is simply not possible with wood-burning stoves.
Dirt during use is completely absent, since the stove runs on electricity, no fuel is burned. In this regard, an electric furnace does not need a chimney to remove combustion products, in a special separate ventilation system. The air in the room does not dry out that much.
Caring for the stove is extremely simple, it does not need to be constantly cleaned from traces of soot, residues of unburned fuel, soot. To start heating, it is enough just to turn on the structure, providing the supply of electric current, setting the required temperature.
Unlike other types, the electric furnace is regulated and controlled very simply. The thermostat is installed directly in the steam room. The temperature during the entire use is maintained exactly at the level that is set, which is a huge plus. The thermostat has protection against overheating, which is very important when installing a do-it-yourself sauna stove.
The stove is safe, no carbon monoxide is emitted during its use, there is no open flame, which does not pose a danger to the wooden furnishings of the sauna.
The dimensions of the furnace are compact, its weight is small. You can install this design in any convenient location, there is no need to pre-install a massive foundation, a small pedestal for equipment is enough, in some cases a small protective brick wall is required, which ensures the safety of use during recreation.

How to make an electric furnace with your own hands?

Furnace layout.

Electric stoves for saunas are extremely simple in design. Typically, this body sheet metal, inside which heating elements are located - heating elements. A crate is installed on top, which is completely filled with stones, they must be laid tightly. The design of the body itself can be open or closed - it all depends on which stove it will be more convenient to use for the steam room. Usually these are open cases, which are suitable for receiving not only dry, but also wet heating. Closed sauna stoves can be horizontal or vertical, the structure includes: a conductive bus, a heater, a heat shield. open structures use nichrome wire, which is mounted in a ceramic stand as a heating coil. To connect the stove, it is best to use a three-phase network with a voltage of 380 V, but for small baths, a traditional single-phase 220 V is quite enough. For the latter design, power equal to 3 kW is usually generated. This allows you to correctly calculate the heating power, which depends on the total area of \u200b\u200bthe room and the required maximum temperature. When installing an electric sauna heater, it is imperative to ensure that the housing is grounded. After installation, it is necessary to carry out tests, i.e. during the first start-up of the equipment, measure the resistance level. With properly performed work, it should not exceed 3-5 ohms.

Assembly technology

To assemble an electric heater for a sauna with your own hands, you must perform the following steps:

First, a drawing of the future furnace is drawn up, which depends on such data: the area of \u200b\u200bthe furnace, the required heating power, maximum and minimum dimensions, location. Usually electric furnaces are made small, the main space of their design is a stone cage.
Calculation of the number of heating elements for the furnace. Their number depends on the power of the future design, the size of the furnace, the power of one heating element to be used.
After that, you can start assembling the stove for baths. To do this, the heating elements are fixed on the frame, connected by jumpers. A sheet of steel with a thickness of 3 mm is used as a base, the rest of the parts are attached to it using bolts and welding.
If the frame is ready, it is necessary to lay the stones as tightly as possible on top, there should be almost no gaps between them.
Next is put protective cover, which can also be made from steel sheet like the main structure. Additionally, you can put a brick wall, providing for this the construction of a small pedestal under the stove.
The connection of the electric furnace is carried out using serial, parallel connections of heating elements, it is necessary to have a thermostat, with the help of which the heating of stones will be controlled. In this case, it is recommended to use rotary or drum switches, the control element itself must be positioned in such a way that it is in a convenient place for use. Usually, the regulator is placed in the steam room so that you can independently set a comfortable temperature in the room without leaving it.
The last step is to check the performance of the furnace, the safety and comfort of its use.

Today, for small home saunas, it is best to use not massive brick stoves that take up a lot of space, but small and compact, but convenient electric ones. The cost of such structures can be quite high, but you can save money by installing an electric furnace to heat stones with your own hands. The technology of its manufacture is available. This is a stone cage, in which heating elements are used for heating.

Do-it-yourself electric sauna stove: assembly technology

You can assemble an electric sauna stove with your own hands quickly if you prepare everything in advance. Its main elements: cage, heating elements, stones, it is recommended to install a temperature sensor.

For those who have a dacha or a country house, the prerogative to create a steam room for themselves and for guests is very tempting. Provided that there are no problems with the voltage in the network and on the site, you can do do-it-yourself electric sauna stove and thereby save money.

Note! If you decide to buy a ready-made electric fireplace, choose it based on the temperature regime, electricity consumption and heating power.

Why Choose Electricity?

How to make an electric oven for a bath?

The article talks about safety measures and the installation of an electric stove in a bath with your own hands. How to make an electric oven in the bath yourself - tips

How to make an electric sauna heater with your own hands?

A self-made electric sauna heater will help to significantly save money on arranging a steam room, but it is better to entrust the connection of the finished device to professionals.

Scheme of electric heater control.

Fans of baths are increasingly thinking about the question of the appropriateness of using one or another type of heater. It is unequivocal to say that any stove-heater is superior to all others in terms of the quality of space heating, even the most experienced specialist cannot. And all because each person has his own preferences both in terms of the quality of steam and the appearance of the heating system.

Benefits of an electric sauna heater

Drawing of a small sauna with an electric heater.

But more convenient to use can definitely be called an electric furnace. Pay attention to a number of significant advantages of such a furnace:

It has a small size, respectively, it can be used even in small areas.
Such an electric heater is mounted quite simply and without the use of expensive materials.
For an electric oven, there is no need to additionally think about and assemble gas exhaust and ventilation systems.
There is no need to stock up on fuel.
The need to clean the furnace from combustion products disappears automatically.

The only drawback of electric ovens is the high energy consumption. But now the question is not about saving, but about functionality and reliability. An additional benefit from an electric heater is that it can be used both for obtaining dry steam and for use in a Russian bath.

Necessary tools and materials

Purchased electric heater for a bath is reliable and durable. But it often happens that either the power of such a unit does not fit the specific design of the bath, or dimensions do not allow convenient placement of the heater in the steam room.

Electric heater with heating elements.

There is only one way out: to make the oven yourself. In order to make an electric sauna stove with your own hands, you will need a certain amount of materials and a small set of tools:

electric heating elements;
sheet metal (thickness from 3 mm and more);
wiring;
power regulator (rheostat);
temperature sensor;
electric welding;
Bulgarian;
asbestos;
heat resistant paint;
stones.

Power selection and installation

First, calculate the volume of the existing steam room and select required amount heating elements.

Kamenka for a sauna from a washing machine.

For wooden bath you will need to achieve a power of 1 kW per 1 m² of space. For brick building it will be enough to have a power of 0.8 kW for the same volume. Generally, it is convenient for users to connect all electrical systems to a network with a voltage of 220V. In this case, all heating elements must be connected in parallel.

But first you need to prepare a sheet metal case, inside which all the heating elements will be located.

There is no fundamental difference in the arrangement of heating elements: they can be placed both vertically along the walls and horizontally in the lower part of the body.

Heating elements should be mounted on a metal case very carefully, using sheet asbestos as a gasket between the heating elements and the metal. This material has a minimum heat transfer coefficient, so the body will not heat up directly from the heating elements.

But it will have to be protected from infrared radiation. You will need a heat insulator with a reflective surface for this.

Electrical diagram of the heater with heating elements.

Above the heating elements, it is necessary to weld a metal grate made of thick wire or reinforcement. The lattice must be strong, since a large mass of stones will be located on it.

Try to weld a kind of basket for stones from the same fittings. It will not look very good, but it can be trimmed with elements that imitate forging. Such things will give the steam room a special charm, and you will be pleased to watch the creation of your own hands.

Forged elements can be different: leaves, flowers, various curls. What matters here is not their number, but a skillful combination. Create a pattern that will be pleasing to your eye, and weld all the elements of the resulting design.

Improvement of appearance and protective handrail

The stone needs to be improved. Everybody metal elements we clean the shallow sandpaper, degrease the cleaned surfaces with acetone or gasoline and cover with a primer. After it dries, paint the parts with heat-resistant paint.

And now the stove must be installed in its place of operation and a protective handrail should be placed around the stove. Such a measure is necessary to protect visitors to the steam room from burns. Wooden elements are suitable for such a handrail.

Connecting equipment

Scheme of installation of an electric floor oven.

The do-it-yourself sauna stove is practically made. It remains only to connect it and check its performance. It is very important to correctly calculate the power of the stove and choose the right one for it. power cable. The power of the stove is large enough, so the cable must be selected with a small margin. And the thickness of the core must be appropriate, the insulation is reliable. Connection is made through a thermostat. If you mainly enjoy dry steam, then the regulator can be installed directly in the steam room. But it is much more reliable to place this element in the dressing room. Then the version of the Russian bath will be safe for visitors to the steam room.

Do not forget to ground the body of the heater. It is important!

And now the basket must be densely filled with stones. It should be remembered that the greater the total area of \u200b\u200bcontact of the stones, the higher the heat transfer will be. It is advisable to use flat-shaped stones for the stove and different sizes. Then you will have the opportunity to put them in the basket as tightly as possible. Try to make the height of the stone masonry as high as possible, since the volume is also very important: the larger it is, the longer the heat will stay in the steam room.

A do-it-yourself electric sauna heater can also be made to connect to a three-phase network.

But here it is especially necessary to make all calculations carefully in order to avoid excessive heating of the heating elements and their premature failure. Careful attention should also be paid to the installation of heating elements in a single electrical circuit. Without certain knowledge of electromechanics and electrical engineering, you definitely cannot do here. And if there is no such knowledge, then seek help from an experienced master.

Sometimes combined types of heaters are used in the interior of steam rooms. In addition to the electric oven, users install a brick wall finished with natural stone. From this, the heat transfer will increase slightly, but additional measures security will be required. You will need to lay a layer of heat insulator between the load-bearing and imitation wall. This is important if the bath is built using a large amount of wooden elements(log house). For brick baths, there is no need for additional walls, since they only increase the percentage of heat loss.

Do-it-yourself electric bath for a bath (video)

A self-made electric sauna heater will help to significantly save money on arranging a steam room, but it is better to entrust the connection of the finished device to professionals.

Do-it-yourself electric sauna heater

Despite the fact that many bath lovers remain devoted to traditional stoves
An electric heater is a practical and effective device for a bath in the yards; electric analogues of stoves are becoming more and more popular every day. The so-called heater can be bought and built with your own hands, and in both cases it will work much more efficiently and heat the bath faster. Among other things, the electric heater is more comfortable than a conventional stove, and its installation does not cause difficulties. What are the heaters and how to connect the sauna stove yourself?

Advantages of electric sauna heaters 220 volts

Despite the fact that electric furnaces have a number of their own features that should be taken into account during operation, they remain more convenient. Basically, heaters are installed in small baths and perhaps this is the only drawback of the electric oven. A wood-burning stove can be equipped in a bath of any size, but if we are talking As for a home sauna, a heater is definitely the best option.

Electric furnaces have a long service life and an attractive appearance

So, what are the advantages of an electric heater operating from a conventional 220 volt network:

Ease of use. All you need is to take the device from a store or equip it yourself - to turn it on, you just need to plug the oven into a power outlet.
heating rate. An electric heater heats up a sauna much faster than a wood-burning stove. You do not need to languish in expectations - turn on the stove in the network and very soon you will find yourself in a pleasant park room.
No fumes and smoke. None bad smell, no soot. You are just enjoying the process.
No firewood needed. This is also a significant plus. You do not need to worry about fuel, just turn on the desired mode and the automation will do everything by itself.
Possibility of adjustment. The scheme of operation of the heater is such that the boiler can, if necessary, be twisted in the right direction. Tens are especially convenient in this regard. If the heat is too strong, simply reduce the heating power. Everything is extremely simple.

Features of an electric sauna heater 380 volts

If an ordinary stove is not enough for you, then for heating large room you can use a powerful heater that requires 380 volts to work. Such a three-phase stove can heat up even a huge sauna for several groups of people in a matter of minutes.

The only disadvantage of this type of furnace is that they require increased voltage in the network.

Can oven can be various types regardless of power consumption. In addition to traditional Russian stoves, Finnish counterparts, which Harvia is launching on the market, have gained high popularity today.

Electric boiler for a bath with a heater: safety of operation

Undoubtedly, a wood-fired oven is a tribute to tradition. However, in addition to all the previously listed disadvantages, fire is also an elementary danger. It can burn, and even worse - lead to a fire. An electric boiler with a heater is much safer, since such a stove is not associated with the presence of fire at all.

The only danger is a short circuit, which can cause a fire during the operation of any electrical appliance.

Before you start using the electric boiler with a heater, you need to carefully study the instructions

When buying or building an electric heater with your own hands, be sure to take care of safety - it is best to use a heat-resistant cable that will not melt in a bath, carefully insulate the boiler so that it does not heat the objects surrounding it.

Do-it-yourself electric heater construction and connection

And now the most interesting thing is how to create a stone in the bath with my own hands, because in this case you will get the opportunity to fully control the entire process and take into account every nuance that is important for you. First of all, you should choose a heating element, a heating element. It is on its effectiveness that the work of the heater will depend. It is advised to buy a heating element made of high-strength stainless alloy, it will allow you to reuse the furnace without loss of efficiency.

Modern electric heating elements are capable of heating the oven to a temperature of 800 degrees, which is quite enough to heat a small bath. The main material of the furnace is metal, it should be grounded and a resistance level of 3 to 5 ohms should be achieved.

The sauna heater must be protected from flammable materials

The order of the main assembly of the furnace should be approximately the following:

We carry out measurements and calculations. It is necessary to calculate the area of \u200b\u200bthe heated room and calculate the required power of the furnace.
Depending on the required power the required number of heating elements is taken, since the heating area depends on their number.
Next, the heating elements are installed and securely fixed.
Heating elements are covered with a steel sheet, the thickness of which should be at least 3 mm.
Stones are laid out on the sheet, which will heat up. All selected stones must be in close contact with each other, otherwise you will not avoid serious heat loss. Densely laid out stones are a guarantee that you will not heat the air.
The whole structure should eventually be hidden by a protective casing - either made of metal or brick. In the case of metal, you need to take a multilayer material, otherwise the oven can seriously burn you.
Connect the heaters to the mains and test the operation of your homemade stove.

Choosing and buying an electric furnace for a bath

If you do not want to mess with the construction of the furnace with your own hands, then we advise you to simply buy a finished model. You can choose among many options on the market. You can compare the models with each other in the final choice by such parameters as heating power, heater type, energy efficiency, controls, appearance.

As for power, everything is simple here - you should not buy a stove that is too powerful for a small sauna. Take the heater for a specific room, believe me, the declared power will be enough. As for the type of heater, it can be tape, heating element or combined. In most cases the best option- heating element heater. Controls are also important when choosing, for example, high-quality models have a number of operating modes and all settings can be controlled from a remote control. Agree, this is much more convenient than going to the oven every time and turning the settings.

Thus, the electric heater is a modern analogue wooden oven for a bath. An electric oven works more efficiently, faster and is much more comfortable to use. You can either buy a finished model or make a stove with your own hands, since this is not at all difficult. To make a heater, you will need heating elements, mains-operated heating elements, as well as metal, stones and, possibly, bricks to make a protective wall.

Do-it-yourself electric heater: electric sauna heaters 220 and 380 volts, electric boiler for a sauna with a heater

Do-it-yourself electric heater - what is it, what is it for and how to do it right? The answers to these and other questions of interest to home masters are later in the article.

The term "muffle furnace" itself means nothing to most people. No, this is not another variety. heating appliances to save on fuel. This is a device designed for firing ceramic products, smelting metals, cupellation, creating single crystals, etc. In medicine, they are used to disinfect instruments.

Despite its compact size, a household unit will cost 35-48 thousand rubles, which is quite expensive for making hand-made and ceramics. Therefore, many are looking for how to make a muffle furnace with their own hands. We offer to arm ourselves with a number of tools, recall the school physics course in thermodynamics and start manufacturing.

Varieties of muffle furnaces

By design features devices are divided into:

tubular or cylindrical;
horizontal or vertical.

By type of heat treatment composition:

air;
vacuum;
based on inert gas.

Only an air muffle furnace can be made at home, therefore it is about it that the article will be discussed.

According to the features of thermoelectric heater:

gas;
electrical.

Of course, a gas furnace will bypass in operation 3-4 times cheaper than an electric one, due to fuel savings, but such a furnace, firstly, is prohibited by law to manufacture and use, and secondly, it is technically extremely difficult to make a muffle furnace with your own hands on gas.

Due simple materials the stove can be made in any convenient form, including one that is ideal for the interior of the room.

Device manufacturing

In this case, we will tell you how to make a do-it-yourself vertical muffle furnace for firing ceramics.

To do this, you will need the following tools:

angle grinder (grinder) and 1-2 circles;
electric arc welding and electrodes;
metalwork tools, including wire cutters;
2mm nichrome wire.

and materials:

2.5 mm steel sheet or used oven body;
corner;
fittings;
basalt wool;
refractory fireclay brick;
refractory solution;
silicone sealant.

Main elements

Frame

Ideally, as the basis of a homemade muffle furnace for fusing or cupellation, the body of an electric oven or miracle stove is suitable, since it already has all the necessary insulation. It will only be necessary to remove or remove all plastic elements.

If it was not possible to find such an oven, the body can be welded from a sheet previously cut into blanks. Weld all the sidewalls, clean the seams with a metal brush or grinder and cover with a primer.

The manufacture of the case from sheets, although a little more complicated, allows you to make the design that fits the size of a particular room.

Heating element

A key component of the device, since the temperature in the furnace and the heating rate depend on it. You will also need to make a thermostat for the muffle furnace with your own hands, or purchase a ready-made one. A nichrome wire will act as a heating element, the diameter of which is selected depending on the maximum temperature. The minimum and most consumable diameter is 1.5-2 mm.

Nichrome on a standard spiral can withstand 1100 degrees, but it is necessary to exclude air from entering, otherwise it will burn out. Fechral is best suited for a muffle furnace - it working temperature 1300 degrees, and he is "friends" with the air.

Any electric muffle furnace, even the smallest, made by hand, when heated to 1000 degrees, consumes about 4 kW. Before use, check all wiring and set the automatic stabilizer to 25 A.

thermal insulation

The most important aspect of the work, which is responsible for the integrity and efficiency of the entire structure. Inside the muffle furnace, fireclay bricks are installed on fire-resistant glue. According to the size of the furnace, it is cut with a grinder. Basalt wool is used on top.

On some crafting forums muffle furnaces It is recommended to use asbestos for masonry. It is indeed a fire-resistant material, but already at a temperature of 650 degrees +, it begins to release carcinogens.

Making a homemade muffle furnace

The first point can be skipped by those who use an old oven as a body.

How to make a body

Cut out a rectangle right size, is bent into a cylinder and a seam is welded. Next, from the same sheet, cut out a circle of the appropriate diameter and weld it to the cylinder. You get a resemblance metal barrel, the sides and bottom of which should be reinforced with reinforcement and corners.

The volume of the barrel is calculated in such a way that there is enough space for insulation (wool and bricks) and for fired materials.

The body can also be rectangular - the shape does not affect the quality of the furnace and the heating efficiency. In the video, you will see how to make a rectangular muffle furnace with your own hands from similar materials.

Video 1 DIY muffle furnace with a description

Furnace thermal insulation

Basalt (stone) wool is laid out along the perimeter of the structure.

Why is this type mineral wool chosen? For several reasons:

incombustibility - it is used even as a barrier to open fire. Cotton wool can withstand temperatures up to 1114 degrees, after which it begins to melt, but not burn;
natural components - basalt, from which cotton wool is made, is absolutely natural material, therefore, even when heated, it does not emit any harmful substances, in contrast, for example, from cotton wool made from slag;
minimum thermal conductivity, which is only 0.032-0.048 W / m / K, which is even less than that of expanded polystyrene.

Cotton wool is attached to the body with special ceramic buttons.

This is followed by thermal insulation with fireclay bricks. Just such a material is required, since it consists of 75% refractory clay and will not burst during the operation of the furnace.

Take 7 bricks, number them for convenience, make them look like a pipe. Next, cut the ends with a grinder so that the pipe is as round as possible.

When the bricks are cut and assembled, tighten them with wire and check how symmetrical the structure is.

You make a 6 mm spiral of nichrome wire, for which you wind it on any round object that is suitable in diameter, you can even use a pencil.

Please note that the oven can only be operated with continuous temperature control. Otherwise, it's just an expensive, but very dangerous toy. The only real sensor option of such high temperatures(more than 1000 degrees) - thermocouple. You don’t need to look for platinum for this, this option is quite suitable:

iron-constantan, 53 mV/deg, thermo EMF;
nickel-iron, 34 mV / deg., thermo EMF.

Unroll the bricks and cut into inside at a slight angle grinder furrows under the spiral. Check their evenness with a level and position them so that the turns go from the very bottom to the top. It is strictly forbidden to allow the turns to touch - there will be a circuit closure. After cutting the grooves, insert the spiral and assemble the entire structure again.

Bring out the ends of the spiral and connect them to a 25 A machine.
Now you take the previously prepared steel cylinder, put fireclay bricks on the bottom of it, cut so as to completely cover the entire bottom, fill them with refractory glue. Next, place the assembled thermal structure and also fill the space between the barrel and the structure with a refractory compound.

Photo 12 Finished construction housed in a steel case

You can turn it on only when the whole structure is completely dry. 3-5 days after manufacture, turn on the device at full power, but do not close the lid - if evaporation starts somewhere, turn it off and leave it for another day.

Cover making

Cut out a circle from steel, identical in diameter to the already fully assembled structure.
On top of the glue, “plant” fireclay bricks - it will provide sufficient sealing.

Weld handles on the sides so that it is convenient to lift and remove the lid, and a latch for closing.

Cover the edge with refractory silicone, before that the surface must be degreased (even White Spirit will do).

Recall that when the oven is in operation, it must be closed. Excessive air ingress will lead to rapid wear of nichrome.

The simplest muffle furnace for ceramics

To make such a simple device, you only need an ordinary electric stove, a clay pot and a piece of fireclay brick.

Put a piece of brick on the stove so that the ceramics being fired do not touch the spiral on the tile and cover it with a pot. The power is controlled by the thermostat.
Now you are watching the pot - as soon as a red light begins to shine through its walls, you mark the time for firing. As a rule, it is 10-12 hours.

Safety

It is possible to work with the stove only on condition that there is grounding.
It is forbidden to start work if there are chips or cracks on the body.
It is forbidden to touch the device during operation.
It is strictly forbidden to touch the running coil.
During operation, the oven requires constant supervision.

Despite the relative ease of manufacture, such a device is not very common among home craftsmen. "Guilt" to this high costs for electricity. Someone thinks that it is possible to make a muffle furnace on wood - well, if you can find a log with a calorific value of 14,000 kcal / kg, then yes, it will work. Although it is still better to use forge- it was in such conditions that the first such furnace in history was invented.

If you still have questions about how to make a muffle furnace with your own hands, watch the video instruction.

Each owner who has his own country house wants to build a bath or sauna on his territory. The furnace plays a big role in this case. You can buy a ready-made model or create it yourself and save cash. An electric oven for a sauna and a bath will be an excellent option. Having decided to buy a stove, you should approach the choice with all responsibility. Let's look at this issue in more detail.

The subtleties of the selection of an electric furnace

When buying, you should pay special attention to such characteristics as: temperature conditions, the degree of humidity that the oven will give, as well as reliability and functionality. But these are not all important characteristics.

You should focus on:

the full volume of the steam room;
electric furnace controls;
heater type;
design view of the furnace;
certificates of conformity.

The volume of the steam room

Most often, the output power of the electric furnace is calculated based on the volume of the steam room. One cubic meter requires a power of 1 kilowatt electrical energy. You should also take into account the energy capacity of the room so that there is no short circuit or knocking out of traffic jams.

Electric oven controls

Also an important element is the control panel, with which you can adjust the heating temperature, as well as heat support and the time to turn off the heater.

Heater type

He is the most important parameter. Heaters by type are divided into: tape and heating elements, as well as combined. Let's look at each separately.

Steam lovers do not always necessarily need to seek the services of specialists for the construction of a heater. If you have elementary building skills, it is enough to learn how to build a sauna stove with your own hands.

Tenovye heaters. They are also called tubular. They can heat up to a temperature of 800 degrees Celsius, but such heating elements are not long-term due to their fragility. Therefore, it is best to buy an electric stove for a sauna or a bath with expensive heating elements made of a stainless metal alloy. They can withstand repeated use.
Tape heaters. They will quickly raise the temperature in the steam room to the desired temperature. Such heaters are popular due to their economy and environmental friendliness.

A combined electric furnace for a bath or sauna combines a heating element and a tape heater, but its price is much higher. The advantage that such an electric oven has is that it is able to heat the steam room in the shortest possible time and precisely to the desired temperature.

Advice! If possible, you should not save, it is better to purchase a combined electric furnace, as it is more functional.

Furnace design

A modern electric sauna and bath stove can be made in a variety of designs and have a variety of sizes.

Such electric heaters can be located in the center or in the corner. They are attached with specialized brackets. Such an electric furnace for a bath or sauna can be made not only of metal, but also of facing stone, and in any case it will look elegant.

At its core, the facing stone can be soapstone, serpentine, soap magnesite, which gives the appearance of the interior not only aesthetics, but also allows you to create an excellent thermal regime in the steam room, and also has a beneficial effect on the human body.

Certificate of conformity

Before buying, you should familiarize yourself with two certificates: for the products offered and for its fire safety.

Advice! Installation and connection of the electric furnace must be carried out by professional electricians, in full compliance with Russian SNIPs.

Types of electric furnaces

electric furnaces for baths and saunas differ in the required mains voltage;
with a steam generator for a bath. It turns out a real steam room with light steam, as well as medium temperature regime and pleasant microclimate;
Finnish ovens. They are manufactured by Harvia, which is recognized as a leader among manufacturers of electric stoves for baths and saunas;
Russian ovens.

Advantages and disadvantages

Bath electric furnaces have earned their fame due to the fact that they:

quickly and evenly heat the room, maintain the temperature;
do not have a chimney and, accordingly, dirt and ash;
stronger and more durable;
easy to manage and use. You just need to set the desired temperature and you can prepare for bath procedures;
have a built-in or remote control panel with adjustable parameters, which most models are equipped with. You can turn off the heater at any time;
have protective fuses that are built into the thermostat. They do not allow him to overheat;
due to lack carbon monoxide are absolutely safe;
save time;
equipped automatic shutdown heating elements and well-thought-out cycles;
compact.

The only disadvantage of these furnaces is the high cost of electricity.

Making an electric furnace with your own hands

Before you start building such a furnace, you need to decide on its type and style. After which you can start self-assembly stove electric stoves. They are most often used in the construction of saunas, where the air must be dry.

The main element that an electric oven or mini-oven is equipped with is a heating element. Therefore, you should decide on its type.

Furnaces closed type well suited for both vertical and horizontal installations heating elements, which includes such a structure as: a busbar that conducts current, as well as a heater or heat shield.

In the manufacture of heaters open type nichrome wire is always used, which is laid spirally in a ceramic stand.

Creating a heater

It is best to use a three-phase power supply for such stoves, which creates a voltage of 380 volts, but if the bath or sauna is not very large, a single-phase one with a voltage of 220 volts may also work.

Advice! You should be guided by the fact that a single-phase furnace can produce a power of three kW, that is maximum area the premises should be no more than 3 square meters.

Close attention should be paid to the metal furnace body, which must be grounded both during the first start-up and during further operation. When changing the resistance, the parameter should be in the range from three to five ohms.

Assembly technology

Full installation of the electric furnace takes place in several stages:

you need to calculate the dimensions of the electric furnace and its power, based on the area of \u200b\u200bthe bath;
based on these calculations, you need to calculate the required number of heaters;
after that, you need to install the heaters, fix them and connect them with jumpers;

then you should take a steel sheet of the desired size with a thickness of about three millimeters and fix it using bolts or welding;
further, you should lay out the stones as close as possible to one another, while removing all the gaps;
the next step is to install a protective casing, for this you will need sheets of metal, or installation of a brick wall;

then the device should be connected to electrical network, set using the thermostat or remote control.

Advice! It is best to install drum or rotary switches for such furnaces.

Safety requirements for the installation of stoves for saunas and baths

Among the main rules:

having its own ground loop. If it doesn't exist, then it needs to be made. To do this, you need to connect the zero terminal of the distribution board to the ground wire of the electric furnace;
The heater must have a working emergency stop device. It should work without errors and errors under any short circuits, air overheating. Read also about on our website.;
to connect the oven to the electrical panel or socket, a heat-resistant and moisture-resistant cable that can withstand temperature conditions must be used.

Important! Compliance with all safety requirements is mandatory, as incorrect installation of the furnace or non-compliance with regulations can lead to a tragic situation.

Video: review of sauna stoves

An electric sauna and bath oven can be installed by yourself, but it is best to enlist the help of a professional electrician. The modern market provides many options and models of stoves, but the choice should be approached wisely, based on the required and suitable characteristics of a particular steam room.

Electric stoves for a bath are an opportunity to create a cozy and comfortable atmosphere for taking water procedures. This type heaters is not only reliable in operation, but also safe, as it excludes the use of explosive gas or solid fuel, which emits harmful substances during combustion.

The main characteristics of electric furnaces

Previously, people could not imagine a bathhouse without a heater, crackling and the smell of burning wood in the stove. But now many prefer a more convenient and functional electric heater. It is good not only because it takes up little space in the room, but also because it does not require constant intervention to maintain the air temperature in the room.

An electric stove for a bath is a device that generates electricity into heat. Inside the body there is a heating element lined with bath stones. During operation, the heating element heats up to the desired temperature and heats the stones, which already give off heat to the room. This type of heater is called "electric heater".

Its main elements are:

heater body;
heating elements;
bath stones.

Previously, electric stoves were made for the Finnish sauna. They heated the air in the steam room well, making it very dry. Therefore, lovers of a real Russian bath did not like electric sauna stoves at all.

Now on sale you can find models of electric heaters that are equipped with a steam generator. They allow you to make the air in the steam room humid, like in a Russian bath.

Electric furnace device

An important indicator is the number of bath stones in the oven. It is from this that the power of the unit will depend and allowable voltage online. So, for example, electric furnaces with a large volume of stones that can be poured with water consume a lot of electricity, so they need a voltage of 380 volts. But simple small-sized ovens can operate at a voltage of 220 volts.

In addition, the type of heating element is considered an important indicator:

Tape.
Tubular.
Combined.

Tape heating elements are environmentally friendly, quickly heat up the room, and also perfectly withstand repeated thermal loads. But tubular heaters are not durable and consume more electricity during operation. The most expensive are combined heating elements, combining the two previous types.

Having decided to install an electric heater in the bath, you need to weigh all the pros and cons. After all, like any other device, electric stoves for saunas or baths have their advantages and disadvantages. The positives include:

rapid heating of the room;
space saving;
long-term maintenance of the temperature in the room;
ease of maintenance of the device;
eliminates highlights carbon dioxide, as this happens when a wood-burning stove is operating;
safety during operation, compared with gas boilers;
simplification of heater installation;
does not require fuel reserves for the operation of the unit;
eliminates overheating of the device due to automation.

But the main disadvantage of such heaters is their high cost. This applies not only to the purchase of a stove, but also to maintenance, since electricity consumption is considered the most expensive heating method.

Criteria for choosing electric furnaces

In the market of electrical goods, there is a huge selection of various models of electric heaters. But how to choose an electric furnace among such a variety? What indicators should be considered when buying equipment? The main selection criteria are:

type of heating element;
type of body of the electric furnace;
the size of the electric heater (depending on the mass of stones);
way to control the unit;
product design.

Among the heating elements, experts distinguish a combined type. It heats up the room as quickly as possible, but it costs a lot of money. Therefore, if you choose a good, but not too expensive heating element, stop at the tape type.

Electric furnaces are of open and closed type.

Depending on the volume of the steam room, electric furnaces are selected. For this, a special calculation of the heater power is made: per 1 cu. a meter of steam room volume takes 1 kW of electricity. Having calculated this, find out the maximum possible voltage (220 V or 380 V) to prevent a short circuit.

Electric furnaces are divided into three groups according to the volume of stones:

from 20 to 40 kg (for small spaces designed for 4-5 people);
from 60 to 120 kg (served large rooms for 8–10 people);
more than 200 kg (large commercial heaters).

The adjustment method is the presence or absence of a remote control remote control. On sale there are models with a remote control and built into the heater body. The choice in this case is individual for each individual.

Electric furnaces are of two types: wall and floor.

At the same time, they are performed in different styles just like wood burning stoves. The body can be metal or trimmed with stone. As they say, "any whim for your money." Can be ordered corner models, oven for mounting in the middle of the room or other options. Facing stone will give the product not only elegance, but also durability: talcomagnesite or talcochlorite inlay protects the case from thermal drops, as well as hard infrared rays.

Highlight the metrics that are important to you good heater. Calculate the electricity consumption, and also decide on the installation location of the unit. After all, an electric furnace is not a cheap pleasure.

How to make a bath unit yourself

To build an electric furnace with your own hands, you need to decide what type of heater you need - closed or open. Main elements homemade unit there will be a body, tubular heaters and a mesh in which bath stones will be placed. For a closed type furnace, in addition to the heating element, a thermal valve and a conductive bus are also required. And for open-type products, nichrome wire is used, which is laid in the form of a spiral in a ceramic stand.

If the stove is quite large, you will need a three-phase network (380 V), and for small heaters, a single-phase network (220 V) is enough. If the case is made of metal, then take care of grounding in advance. And when you first connect, measure the resistance, the norm of which is no more than 5 ohms.

To make an electric oven with your own hands, follow the instructions.

Having decided on the main nuances, proceed to the calculations of the dimensions of the future furnace, respectively, the required power and heating area.
Calculate the required number of heating elements based on the power of the unit.
Do graphic image future design.
Fix the heaters on the frame and connect them with jumpers.
Take a 3 mm thick steel sheet and fasten it with welding or bolts.
Place the bath stones tightly in the gaps between the heating elements.
Install the protective cover with a steel sheet, or build brick wall, which will perform a protective function.
By connecting in parallel and in series, connect the heater to the mains using a thermostat or remote control. It is thanks to the regulator that it will be possible to control the heating of stones in the furnace.
Check if the oven performs all the specified functions.

Check the safety of the homemade product.

The stoves are too big, so they take up a lot of space in the steam room. In addition, the owners need to take care of fuel supplies and maintain the air temperature in the room, which is not very convenient during the holidays. And the cost of the finished heater is quite high. Therefore, to save money, you can do heating equipment with my own hands.

Installation of an electric furnace in a bath

The unit must be installed in accordance with all the requirements of SNIP. This document regulates the rules for the installation of electric furnaces, taking into account fire safety. The main criteria according to the requirements of SNIP are as follows:

units can be installed either in the center of the room or near the exit from the room;
mandatory organization of supply ventilation by making a hole in the area of the heater;
the electric furnace is installed on a metal sheet or other coating that belongs to non-combustible materials;
when installing an electric furnace, it is important to take into account the distance between the heater and the wall, which should be at least half a meter.

Having studied all the fire safety requirements, proceed directly to the installation of the furnace. To do this, prepare in advance the supply of copper power cables. In the next step, wash the stones and place them in the right amount into the oven.

Connecting an electric furnace without bath stones will lead to burnout of heating elements.

Separately, you need to do ventilation. To do this, make a hole near the electric furnace at a distance of 5-10 cm from the floor. It will serve as an air inlet. An exhaust hood is made on the opposite side of the wall, and ventilation is installed on the same wall in the highest possible place in the opposite corner from the inflow.

An important point is the installation of the control panel, which will be located in a room where there are no high temperatures. The power of the shield must correspond to the power of the electric furnace. To avoid heating walls or contact with wires, all wiring is installed in a special tire made of fire-resistant material.

Electric furnaces are not required special attention during operation. They are pretty easy to use. But the owners need to take care of compliance with all fire safety rules and ventilation of the premises. Only in this case the organization electric heating will bring joy and comfort while relaxing in the steam room.
