The tradition of visiting the bath has existed since ancient times. Many people build a bathhouse in a private house, in outhouses, in the country or in the country. In order to want to return to the bathhouse from time to time, you need to properly equip it and conduct all communications.

One of the most important systems is heating. If you make a stove for a gas bath with your own hands, then you can effectively heat this room. The market offers a wide selection of diverse gas equipment. But buying it may be too costly.

Why spend so much money on heating the bath, which you visit not so often? This problem is solved in a simple way. There are many different schemes of home-made stoves, according to which you can independently assemble a high-quality device at home.

Preparing the bath for equipment installation

Which oven should I put? This is one of the first questions that the owner asks himself when he has a desire to build and install a gas stove for his beloved bathhouse with his own hands.

Any normal owner wants to ensure a safe and comfortable operation of the devices used. You can assemble the furnace from a variety of materials: both expensive and cheaper.

The advantages of gas furnaces
Gas-fired sauna stoves are in direct competition with wood-burning stoves. This is due to ease of use, lack of need for constant care, cost-effectiveness. You can heat and prepare such a device for operation much faster than a solid fuel unit

Most often, metal, stone or brick structures are assembled. This is due to high reliability, low financial costs for the purchase of necessary parts, ease of assembly and installation. At first it may seem that assembly is a complex process, but in fact it is not.

Before gasifying the bath, make sure that it holds heat well.The room must be fully thermally insulated and insulated both outside and inside. Only in this case the heat loss will be minimal, and the furnace will perform its functions as efficiently as possible.

Choosing a gas furnace installation location

If the bathhouse has already been built and it remains only to choose a convenient method of heating, then it is worth choosing the suitable design of the gas furnace. On the other hand, you can choose the appropriate version of the device and slightly adjust the bath room during installation.

That is, it is advisable to initially choose a future heating option and build the building in accordance with this choice.

Long service life
The process of installing a homemade gas furnace is quite simple. It is only necessary to adhere to the basic safety regulations. A well-made stove with timely repair work can last the owner five or more decades

Installation and installation of a gas bath stove is carried out, as a rule, in the steam room, in the adjacent washing room or partially in the rest room. The main task of the furnace is to ensure complete heating of the entire bathhouse and maintain a constant temperature.

To reduce heat loss, a home-made gas stove is best placed in the center of the bathhouse. It was found that if the heat source does not contact directly with the walls, then a significant decrease in heat loss due to the heat cap is observed. Heat does not leave the building through the walls.

Warm air circulates throughout the steam room. It rises from the center of the room to the ceiling, where it is reflected from the vapor barrier with a reflective layer and spreads over the entire area of ​​the steam room.

Thus, it will be possible to steam in the room for as long as possible. However, it is not always convenient to install a gas furnace directly in the center of the steam room.

Brick oven
Brick and stone stoves have a long heating time. So, if you want to steam up, you need to start heating the stove about 8 hours before visiting the steam room. However, such furnaces retain heat several times longer than metal

Choosing the installation location of the furnace from various options implies its advantages and disadvantages. If you install a homemade gas stove in a steam room, you will need to additionally carry out a ventilation system.

This is due to accelerated oxygen consumption. The advantages of this installation method include the ability to control the temperature without leaving the steam room.

Installing a gas oven in the bathhouse with your own hands in the relaxation room gives the following advantages:

  • The absence of accelerated burning of oxygen, therefore, there is no need for enhanced ventilation of the room.
  • In the steam room, the space that is useful for visitors is not occupied, therefore, it will accommodate more people.
  • The steam room will not be polluted by burning and other waste associated with the operation of the furnace.
  • Gas oveninstalled in the adjacent washing room or in the relaxation room, usually heats not only the steam room, but also all other rooms.

This type of installation will require additional manipulations such as creating holes in the wall leading to the steam room. However, if this type of installation is foreseen in advance, no additional work will be necessary.

Fire safety

In order to avoid negative consequences after installing a gas furnace, it is worth taking care of fire safety.

All combustible and flammable materials or objects must be placed at a certain distance from the device. A half meter distance will be enough. You should also maintain the distance of the furnace from the wall in the range from 5 to 15 centimeters.

Safety precautions
Installation of a sauna stove requires a serious approach and safety measures. In particular, the distances between flammable objects and the furnace must be observed. The burner must be equipped with a fuse.

In the place of installation and installation of a homemade gas bath stove, insulating sheets of refractory material should also be laid out or brickwork should be done.

It is also necessary to protect the ceiling with fire-resistant sheets with basalt cardboard or other material. It should be borne in mind that the protection area should be greater than the dimensions of the furnace by about thirty percent.

The design is recommended to be positioned so that the door providing access to the burner opens to the doorway and the heater door opens to the wall. In a room heated by gas, there must be a means for quickly extinguishing a fire in cases of fire. There should be at least one small window in the dressing room.

The construction of the walls of the furnace
The construction of a stone or brick bath gas furnace is carried out according to a previously developed scheme. Such a scheme involves a certain logic and sequence of actions when laying the next row of refractory bricks and the installation of additional elements

When erecting the walls of the furnace for the bath, it is worth using refractory bricks, and for laying the combustion chamber bricks made of fireclay clay.

The masonry mortar is mixed with clay and sieved sand. For the foundation of the stove and the outer part of the chimney, cement is used instead of clay in the solution. To strengthen the foundation of the future furnace, it is necessary to reinforce the foundation reinforcement and use galvanized sheet metal to protect the floor in front of the door of the combustion chamber and the closed heater.

To equip a brick stove, you will need to purchase a grate, a furnace door and a blow door. Also, if you plan to install a gas-fired oven, you should take care of the place in which solid fuel will be located so that moisture does not get on it.

In order for the chimney from the gas furnace to serve for a long time, asbestos-cement or metal stainless pipes are used for its laying. The height of the chimney is usually planned at five meters above the level of the burner.

Chimney for a sauna gas stove
The laying of the chimney should be approached with particular responsibility. There should not be any holes, cracks and crevices in the stove array or in the chimney. Their presence can cause carbon monoxide to enter the room and poison people.

It will also be necessary to provide a supply of water and gas. Water can be supplied by connecting a water pipe or from tanks using a compressor. For the supply of gas, all options are used: from connecting to the gas main, and the use of a gas tank or cylinders.

The foundation for installing the stove

Depending on the weight of the future furnace, the necessary requirements for the surface on which it will stand change. Homemade metal gas stoves are most conveniently installed on a flat concrete surface, previously covered with tiles, porcelain stoneware or other decorative materials.

In the very first row of bricks, when building a brick gas furnace, it is important to observe the thickness of the seam. Each brick of the upper row should cover the joint of two underlying bricks. The height of the foundation does not reach the finish floor by about 20 centimeters

If the floor in the bath is wooden, then it must be covered with refractory flooring. When it is planned to install a really large kiln, weighing more than 700 kilograms, it is worth adding an additional concrete foundation. It is arranged separately from the bath foundation.

Weight is calculated based on the sum of the following parameters:

  • the weight of the gas furnace itself;
  • weight of stones;
  • weight of filled water tanks;
  • chimney weight;
  • weight of the protective screen installed in front of the gas furnace.

In most cases, a concrete base is planned to install a gas furnace in the bathhouse.

The following nuances are highlighted when pouring concrete:

  • the area of ​​the foundation should be greater than the area of ​​the base of the furnace around the circumference by about 20 centimeters;
  • the depth of the foundation under the furnace should not be less than the depth of the foundation under the entire bath;
  • shrinkage of the bathhouse and furnace should be independent, therefore, it is not necessary to link the foundation of the building and the foundation of the furnace;
  • the foundation of the furnace should not reach the floor level by about 20 centimeters, this cavity is laid with bricks.

So, given all the recommendations, pouring the foundation will consist of the following actions. The foundation pit is prepared first. Then, work is carried out to install the formwork and lay the reinforcing mesh and other reinforcing materials.

Then concrete is poured directly. Refractory material spreads, roofing material or roofing, and several rows of bricks are laid on it.

In order to install the stove on a wooden floor, you need to make sure its strength. After that, cover the wood with a refractory coating: basalt cardboard and asbestos. From above lies a metal sheet, refractory brick, natural stone or porcelain tile.

If the owner’s idea involves inserting a stove, it is necessary to lay the space between the wooden wall and the stove, as well as the path of the chimney with refractory materials or fireclay bricks. However, it is worth remembering that between the furnace and fire protection it is necessary to leave an air gap. This space is usually filled with stone wool or basalt cardboard.

Features of homemade gas stoves

A gas stove differs from a wood-burning stove in that it uses gas for kindling. Therefore, in such a device, instead of a window for laying firewood, a cavity for the burner is mounted. However, you can also make a gas-wood stove with your own hands.

Metal furnace
A metal bath stove is often bricked. Lining is made in order to increase heat transfer. In addition, the metal construction with a brick casing cools much more slowly.

Most gas furnaces have the following design. A pressurized or atmospheric gas burner is mounted in the housing of the device. Fuel is supplied through a hermetically connected gas hose or pipe.

At the top homemade gas stove there is a closed heater or an open tray with stones that are heated by the burner, as well as a device that removes combustion products.

For self-assembly, it is imperative to take care of installing a thermostat and a fuse that cuts off the gas supply if the burner goes out. A gas chamber containing combustible gas is usually located under a pallet of stones.

The advantages of homemade gas stoves for a bath include:

  • compact size, because gas stoves do not have a firebox and an ash pan;
  • fast heating to the required temperatures;
  • economical resource consumption;
  • there is no need for constant care of the device;
  • when installing a water tank, you can also heat the water.

The disadvantages include the need for a gas source. For example, if the bathhouse is located outside the city in a non-gasified area, some owners will have to buy gas cylinders or install mini gas tank. However, there is a plus in this - there is no need to obtain permits.

It is worth remembering that when working with gas, you always need to follow safety precautions.

Burner selection
When choosing a gas burner for a bath stove, it should be borne in mind that the efficiency of atmospheric burners does not exceed 90%, and the efficiency of pressurized burners is more than 95%. However, the first option wins in terms of independence from electricity

When installing an open burning furnace, it is necessary to design and install a ventilation system and a chimney. Also, when burning oxygen, the air becomes drier, so you need to take care of humidification.

Gas cylinder stove

For self-assembly of a gas bath furnace, you will need to collect and purchase the following materials:

  • At the construction market or in a store with gas equipment you need to buy an atmospheric burner.
  • Find an old but not rusty gas bottle. A new cylinder, a large-diameter pipe or a sheet of metal with a thickness of 8 to 16 millimeters is also suitable.
  • For the base of the heater you will need thick metal, for example, a brake disc from a car. He will serve at least a few years.
  • A gas pipe with a diameter of 5 centimeters and a length of about 3 meters.
  • A pipe with a diameter of 10 centimeters, which will be used for gas outlets.
  • Some copper or bronze elements to connect parts.
  • In addition, you will need to acquire the following tools: a grinder, a welding machine, a drill, measuring instruments.

After assembling a complete set of tools, it is necessary to cut off the extreme part of the cylinder with a grinder so that the cut diameter is equal to the external size of the brake disc. Then, using welding or a drill with bolts, you need to attach the disk to the cylinder.

The next step is to prepare the air supply pipe. In a pipe with a diameter of 5 centimeters, about ten five-millimeter holes need to be drilled.

Also, a hole with a diameter of approximately 55 millimeters is made at the bottom of the cylinder. The whole, that is, not drilled, part of the five-centimeter pipe should go out of the tank by about two meters. It must be welded to the cylinder.

Assembly steps
First you need to cut the workpiece with a grinder according to the sketch. Then weld all components using a welding machine. After completing these procedures, you must also grind all welds. The same grinder copes with this task well

In the same way a pipe is welded, which will supply gas. An adapter is attached at the second end of this pipe, with which it will be possible to connect the device to a gas pipe or gas cylinder.

A hole for a chimney is cut out on a cylinder on a cylinder and the corresponding pipe is welded. Using a grinder, a rectangular hole for the door is also cut out. Hinges are welded and the door is hung directly on them. You must also attach a handle to the door.

Thus, a simple model of a gas furnace will be made. Through the pipe gas is supplied to the burner. The combustion process is started, depending on the burner, by piezo ignition or electric pulse.

Metal sauna stove

To get a good steam in the bath, you need a good brick oven. It will allow you to keep heat as long as possible. However, a serious foundation is needed for such a furnace. This requires additional cash costs and time.

In order not to spend money on pouring the foundation, you can make your own metal furnace. The creation of such a furnace does not require a deep study of the schemes, and its effectiveness has been proven by practice.

Despite the fact that the metal furnace heats up quickly, it also cools quickly. This is its main drawback.

In order to assemble such a design, you will need a metal container, sheets of metal or pipes of various diameters, a gas torch, a grinder, a welding machine. Those who do not know how to use a welding machine can make a body from a regular pipe. This stove will not get worse.

Material selection
Gas cylinders and pipes can be selected in other sizes. The size of the required parts depends on the size of the heated steam room. If its area is large, then it is worth making the stove larger. She will cope with her task as efficiently as possible.

The result is an oven about 80 centimeters wide and about one and a half meters high. A heater is mounted on top and platforms for installing a container of water. Thus, to form an atmosphere of soaring in the steam room, it will be necessary to water the stones with water.

When drawing up a conditional drawing, it is necessary to take into account the exact dimensions of all the details. Initially, you need to find a pipe or cylinder of gas with a height of 180 centimeters and a diameter of 80 centimeters. At the same time, the walls of the pipes should be quite thick - from 0.4 cm or more.

You will also need a metal sheet one centimeter thick, a steel bar with a diameter of one centimeter, cast-iron or steel doors, a chimney pipe, gas burner and faucet. All material can be purchased at a hardware store. Still need a tool: a grinder and a welding machine. They can be rented or borrowed from friends.

First of all, at the place where the metal furnace will be installed, the base is prepared. It needs to be made even in level. It is necessary to cover the foundation with refractory material.

Two rows of refractory bricks are laid out on top. Do not forget that the ceiling and all walls at a meter distance from the furnace must be covered with fireproof material.

The manufacture of the furnace is carried out in several stages. First you need to cut the pipe with a grinder into two parts, one of which will be the body of the furnace, and the second will be used to heat the water barrel.

In the lower part of the first pipe section, a grinder makes a rectangular hole measuring 20 × 5 centimeters. This method provides access to the gas burner.

Water tank welded to the stove side
The vast majority of gas furnaces have approximately the same device and sequence of assembly and installation. The water tank is installed on top or welded on the side. If you want to install an advanced model, you can additionally install a number of elements and devices that will automate control of the furnace

In the middle of the first pipe section, another rectangular hole of the same size is cut. Brackets are welded on which the grid will be held. The mesh cells should be smaller than the size of the stones that will be laid on it.

A tap is welded at the bottom of the second pipe. Then a second pipe section is attached to the heater. In this case, it is necessary to check the seam for leaks. Next, you need to weld one door, and hang the second on the hinges.

The pipe is insulated with refractory bricks or other material. After welding all the elements, a torch is installed and the furnace is ready for use. It is worth remembering that a metal furnace is heated to high temperatures, so it is imperative to cover all nearby surfaces with refractory material.

To assemble a gas stove for a bath with your own hands is not difficult. To implement this idea, you must follow safety precautions and follow the recommendations. Thanks to self-assembly, you can save a lot of money, and the effectiveness of such a design is not much inferior to store models. Before you start collecting the stove, you need to carefully prepare the room.

    How safe are such homemade products? And is it necessary to somehow coordinate with the gas workers?

    • Expert
      Amir Gumarov

      If you decide to make a bath stove yourself, then you may not expect to receive an official installation permit from the gas service. This structure is so structured that nobody will give you the go-ahead to install non-certified equipment. Therefore, you will need to certify homemade, as well as obtain permission to install from the fire inspection.

      If you comply with all these requirements, it will take a long time to get the appropriate permissions from all organizations. And even if you solve this issue “in a different way”, it will not be financially expedient, since it will be easier to buy a new stove.

      Therefore, many are not associated with official registration. But here it is worth making a clarification that the project should still be developed and approved at a professional level. If there is any doubt, it is best to consult on any little things.
