Do-it-yourself natural gas oven. The most economical way to heat: a small hard-working gas stove for the home. Device elements. Types of burners

What distinguishes a Russian bath from a Turkish hammam or Finnish sauna? The stove, which is not just a heating device, but its real heart. There is an opinion that this must be a heater, but if there is a connection to gas (main or bottled), then a gas-powered sauna stove will do an excellent job of heating the bath and quickly heating a large volume of water. Such a unit is light in weight, easy to use, does not require regular cleaning of the gas pipeline, words, a real find for lovers of bath procedures.

Among the additional advantages of the equipment are quick heating of the room, efficiency, which is especially important in winter time years and relative ease of manufacture. Currently, the store assortment of heating equipment is quite wide, as well as the pricing policy, but if necessary, we will tell you how to make a do-it-yourself gas bath stove.

The total cost of such a gas furnace directly depends on what material it is built from. The highest quality and most efficient is a brick oven with a built-in inflatable burner, a metal one is an economical option, which is also advisable to be lined with bricks.

Design features

The gas furnace is structurally identical in many respects to a conventional boiler, but differs in quality characteristics associated with the properties of the gas. So, a fuse is necessarily provided in the body, which stops the supply of fuel at the moment the burner goes out, an absolutely sealed gas chamber. But the fundamental difference is still in the supply of fuel - if fuel is loaded into the chamber in a solid fuel furnace, then in a gas furnace - it comes directly from the gas pipeline.

For maximum safety operation, gas cylinders are always placed outside the building in a special container or bunker placed underground.

How to calculate the consumption of natural and liquefied gas

The main indicator on which the calculation depends is the area of \u200b\u200bthe room and the power consumption of the equipment. Also taken into account are outdoor temperature indicators taken in the coldest time.

The calculated indicator, ideally, is always 35-50% higher than the actual consumption, since the air temperature always changes up or down. When choosing ready-made equipment, this fact should be taken into account and instead of, for example, 100 W of energy, you can take 50.

The calculation of the amount of natural gas is made according to the formula:

L \u003d Q / (qN x 0.92),

L - calculated volume of fuel (1 cubic meter per hour);
Q - heating power, kW;
qH - limiting power of fuel combustion, for natural gas 10.175 kW / m 3;
0.92 - efficiency gas boiler/oven.

On average, for heating a room of 100 sq.m. the calculation will look like this:

5 / (10.175 x 0.92) = 0.53 m 3 / h,

which corresponds to the consumption of natural gas per unit of time (hour).

Based on such indicators, it is possible to determine the nominal gas flow in any room for a certain period of time. Since the bath is not operated daily and not around the clock, such an expense will be less.

Bottled (liquefied) gas is more expensive and its consumption will have to be calculated not by liters, like natural gas, but by kilograms. The calorific value of gas remains the same - 10.175 kW / m 3 \u003d 12.8 kW / kg, heating power - 5. We get:

5 / (12.8 x 0.92) = 0.42 kg/h,

which corresponds to 0.78 liters per hour. Given that, 1 liter of bottled gas weighs 540 mg. Based on the approximate number of days and hours of operation of the bath, you can calculate the required volume.

In order to make a stove for a gas bath with your own hands, you should decide on three main parameters:

Material;
What will be the gas burner;
Placement of capacity - the built-in or portable tank.

Now about each of them in more detail.

What materials are used

As mentioned earlier, it is recommended to use fireclay (refractory) brick, metal or stone to make a gas bath stove with your own hands. Stone ovens melt much longer (4-5 hours), but they also keep the temperature 3-4 hours longer than metal ones. Brick are characterized by similar indicators. In turn, metal units heat up faster (in a room up to 50 sq.m. it warms up completely in 2.5-3 hours /), but they also cool faster.

At the same time, metal furnaces are lighter than brick counterparts and it is easier to manufacture them, and if it is lined with fireclay bricks from the outside, then there will be no fundamental difference between the 2 units.

Gas-burners

In total, there are 2 main types of burners - atmospheric and pressurized.

The first option is the simplest, which does not require automatic control and related equipment. With such an atmospheric intensity of the fire, it is maintained by the air entering the chamber through the doors, respectively, the heating efficiency directly depends on the amount of incoming air.

The operation of the inflatable burner is provided by a blower fan, which forcibly draws air into the chamber and also supports the operation of the burner. Given that the fan is powered by the mains, the heating unit is volatile, which means more expensive.

A similar fan is installed in solid fuel, combined and pyrolysis boilers. About that, you will learn in the corresponding article.

Location of the water tank

By analogy with traditional sauna stoves on gas equipment, the water tank can be built-in, removable or remote, that is, located in another room. In the built-in, water heats up much faster, which is facilitated by combustion products in the heater.

To heat water in a remote tank, which can be installed in the same room or directly in the steam room, a pipe system is used.

How to make a gas oven for a bath with your own hands

A permit must be obtained for the installation of a gas oven and its connection. Specifications and the connection procedure in each region must be coordinated with Gorgas services.

This article will focus on the manufacture of a brick gas oven with a burner. Despite the apparent complexity, it is possible to manufacture such equipment, while it is necessary to follow construction technologies and production procedures.

Preparatory process

The main design issue is the location of the future furnace. Optimal location there will be installation for 2 rooms so as to heat all the rooms, including the one where people rest. The power of the manufactured stove will be enough to heat 3 main ones - a steam room, a washing room and a dressing room.

Necessary materials:

fireclay brick;
sheet of galvanized steel;
fittings;
pipe, grate;
clay and sand;
2 doors blower and firebox;
base,
chimney;
mineral wool for insulation,
heater,
burner (atmospheric or blown),
heat resistant steel sheet,
decorative overlays,
automatic control unit for forced draft burner.

Foundation

Before erecting the furnace itself, a proper foundation should be made:

You dig the foundation half a meter below the freezing level.
Pour sand 20 cm thick to the bottom - this is an air cushion that will reduce the risk of soil movement. Sand is poured abundantly with water, on top is a layer of broken brick or construction debris by 20-25 cm.
Fall asleep 10-15 cm with rubble and proceed to formwork. Be sure to make a reinforced frame! Pour concrete from cement, crushed stone, sand (in equal parts) and water (1/2 volume).
Ambassadors of formwork drying, remove wooden frame(as an option - the formwork can be fixed) and cover the entire surface with 2-3 layers of tar (you can use roofing material).

Furnace walls

Be sure to set up a protective wall that will eliminate the risk of fire in the bath. For its manufacture, it is fashionable to use a rifled brick (half), laid on a sand-clay mortar.

The solution is prepared at the rate of 1 part of clay and 1 part of river sand.

For laying the base of the furnace, the bricks are completely immersed in cold water for a few minutes, after which they are still wet placed on the mortar on a bituminous base (waterproofing). The distance between the bricks should vary between 3-5 mm. All subsequent rows are laid out in a checkerboard pattern.

In the 3rd row, you build in the blower door. It is better to fasten it to the base with steel strips.

In the 4th row you make a well for the grate. Cut small holes in the bricks (0.5 cm on each side) so that there is room for thermal expansion of the metal.

Hardware installation

In the 6th row, you also fasten the door for the blower to the steel strips.
In the 7th - grate.
8th - installation of a partition for the construction of a chimney.
14 - tie-in channels for the tank. To do this, you need to make a recess, where the tank will subsequently “enter”.
From the 15th row, the bricks are overlapped in half to make a distribution wall. From 15 to 18 rows, the layout is decreasing.
In the 19th row, a door is installed to release excess vapor.
In the 20-21st - strips for the built-in container, which must also be laid out with bricks.
From the 23rd row, you begin to lay the chimney, the size of which is selected from the size of the bath room. From the side of the street, the pipe must be insulated mineral wool and its height is 1 meter above the roof ridge.

The minimum thickness of the chimney must be at least ½ the thickness of the brick.

For outdoor laying of the base under the chimney, it is recommended to use a concrete solution to prevent it from being washed away by precipitation.

The final stage

After the laying of the furnace is completed, it must be plastered. This is done not only for decorative reasons, but also to improve the thermal insulation properties. For plastering, you can use any available solution, where you add at least a quarter of the volume of alabaster. This will qualitatively improve the finish and allow the materials to "breathe".

In the absence of alabaster, gypsum can be used, but at the same time prepare the solution in small portions. Compared to alabaster, gypsum sets 2 times faster.

When choosing between a main gas pipeline and bottled gas, keep in mind that the latter has a higher thermal power factor. Recall once again that the gas cylinder must be kept outside the premises, preferably buried in a box under the ground.
Be sure to use an automatic block for a gas boiler. This is necessary to stop the fuel supply in the event of any emergency.
The home-made gas bath stove, which was discussed in the article, can be started after 14-20 days, depending on the temperature environment. It is not recommended to bring it to full warm-up at the start-up.
Be sure to use iron barriers between and in front of the wall and the heating unit to eliminate the risk of spontaneous combustion.
Chimney labor is always made of stainless steel.
The maximum distance from the gas burner to the end of the chimney is within 5 meters.
In the room where the gas stove for the bath is installed, it is necessary to ensure high-quality ventilation with your own hands or with the help of specialists.

And here you will find out how the ovens differ from each other, and which one is better to choose in a ready-made version.

Video 3 How does one sauna stove differ from another

In general, we note that a gas stove for a bath - best option. Quickly heats the room, keeps the temperature for a long time, economical in operation, there is no need for frequent cleaning of the chimney. But only this type of heating equipment, subject to connection to the main line, requires a number of coordination actions for subsequent operation.

Recently, gas stoves have gained great popularity, especially in the construction and arrangement of baths. These designs have advantages over their wood-burning counterparts - fast heating of the room. The gas oven can heat a small sauna room in just 3-4 hours, it is economical and convenient to use. It is also worth noting that there is practically no waste when burning gas, so it is often not necessary to clean the structure.

The gas heating system is universal, it is used:

for heating baths and saunas;
as heating boilers when laying heat communications in the room;
as part of boiler structures to provide apartments hot water during the summer period;
if we consider household gas stoves, they are very popular with housewives. Thanks to open fire, dishes on this design are prepared much faster.

Types and features of gas furnaces

Before you build a gas stove for a bath with your own hands, you need to understand the main design features of these structures and their types.

All gas structures are classified:

heating;
household;
heating.

If we consider a stove for a bath or sauna, then it is worth stopping at a heating gas structure.

Heating furnaces are used in autonomous heating systems and hot water supply of private buildings. It should be borne in mind that with high humidity, these structures are practically useless, since they cannot maintain high temperatures.

Gas household structures are cooking stoves, which are often installed in summer cottages. They are unpretentious in care and easy to use, in addition - quite economical.

Gas ovens have different qualifications for:

the type of burner that is installed in the boiler;
method of heating the coolant;
material for the manufacture of the furnace frame;
type of fuel to be used.

There are many varieties of gas stoves, there is another type of qualification - by the type of gas burner:

atmospheric;
supercharged.

The most affordable on the market are atmospheric burners. They are easy to install - you do not need to supply electricity and mount special automation. In this case, injection is involved, under the influence of which air enters the zonal chamber or a special pipe installed by analogy with self-made structures.

It should be understood that this is why the efficiency of the furnace will depend on the supply of oxygen. If the blowing is weak, then the efficiency of the furnace will greatly decrease - gas combustion will be sluggish.

The most complex and expensive design is inflatable type burners, which are directly dependent on electricity. The design feature of this unit is a special fan that blows air into the combustion chamber. The efficiency of the structures is high, its use is universal, since they can be installed in combined furnaces. Atmospheric units can only be installed in gas ovens.

The body material can be different:

stone;
brick;
metal.

Each material has both positive characteristics and disadvantages.

Brick and stone stoves

These designs differ in the duration of heating. If there is a desire to take a steam bath during the day, then you will have to start heating the bath at night or early in the morning. Of course, such a stove cools down much longer, for example, a well-heated bathhouse retains heat for 2 days even in winter if there is a brick structure in it.

Brick structures must be installed on the foundation, since they have a decent specific gravity, they differ little from the classic version of bath stoves. The only difference is that the door will not open access to the furnace, but to the heater, which is located in the furnace itself.

It is worth noting that the cost of a brick oven will be quite expensive, since it will take a lot of material to install it.

As for metal gas stoves, they are much more popular with the townsfolk, their advantages:

Ease of installation.
The ability to build on your own, without the help of a professional bricklayer.
The design has a small specific gravity.
It heats up quickly, so it takes much less time to heat the room.
Economical, especially if you assemble the structure yourself.

Sauna stoves are divided into types according to the type of fuel:

exclusively on gas;
combined.

If everything is clear with the former, then the latter should be considered in more detail, since they are heated both by gas and wood. This versatility has significant disadvantages:

the bulkiness of the structure;
without fail it is necessary to install a blower burner;
complexity of execution;
dependence on electricity;
traditional wood stoves much safer.

As for gas stoves, they can be equipped without a gas pipeline nearby, as they function perfectly on propane, which is freely available and sold in metal cylinders.

In addition, propane compares favorably with natural gas, the thermal energy during its combustion is much more efficient. This gas is economical when heating a small sauna room; you often do not have to refill cylinders.

But there is also a significant disadvantage - the need to equip a special room for the installation of gas cylinders, which should be at a sufficient distance from the building, outside it. It is advisable to prepare a steel container dug into the ground.

How gas ovens work

To have an idea about the device of a gas furnace, consider the main structural elements:

a case, which is made of metal or other material that protects the internal contents;
a fuse that is installed in case there is an attenuation in the furnace - the gas is shut off instantly and automatically;
thermostat responsible for temperature;
sealed chamber. It is on this unit that you should pay special attention when choosing a design in a store or self-manufacturing gas oven. The safety of people living in the house depends on the integrity and reliability of the camera;
the chimney is used to remove combustion products from the bathhouse.

As for the principle of operation - it is quite simple. The gas burner, to which the gas is supplied, is located inside the housing. On the body there is a heater and a chimney. As soon as the burner fires, the combustion process begins in the working chamber, from which the furnace body and stones heat up, and the waste products exit through the chimney.

We must not forget about the tank with water, in which it will be heated from burning in the furnace. It can be installed above the heater and attached to a pipe, which, when heated, will give off heat to the liquid. But some craftsmen build a tank attached to one of the walls of the furnace.

In addition to all of the above, for gas stoves for a bath, it is necessary to build a protective case, which is built on top of the main one, in places where the stove is close to the walls of the bath.

Advantages and disadvantages

Today, gas fuel is chosen by many ordinary people, if there is a similar opportunity in the region, as it is considered the most economical fuel. It should also be noted that gas-fired ovens have a lot of advantages:

The design is simple when compared with solid fuel stoves, for example, gas stoves for a bath do not have huge fireboxes and ash pans - there is no need for them.
Ease of operation of the gas unit. A wood-burning stove must be constantly monitored and fuel should be added as it burns. As for the gas boiler, it is enough to set the main parameters: fuel supply rate, temperature regime, pressure and automation will follow all this. It should be noted right away that when constructing a structure on your own, you should not save on automation - gas requires a responsible attitude.
No need to constantly clean the gas structure - no ash residues and solid waste.

Gas ovens have disadvantages, but there are few of them:

paperwork and permits for the installation of gas equipment - one-time, but there are some difficulties;
sometimes there are difficulties in winter with high fuel consumption;
in some areas, the pressure in the system may decrease, but this is quickly eliminated.

How to make a gas oven with your own hands

If you decide to create a gas oven with your own hands, then it will not be difficult. The main thing is to determine the sequence of work and know the main nuances, which we will consider further,

Don't be afraid complex schemes, which can often be found on the Internet, if you understand how to deal with the drawing, then there will be no problems.

Preparation

First of all, we create a project on paper. It will indicate the pipeline that will be suitable for the bath. You should not do this yourself, as it is likely that you will make mistakes. Contact a special service that has specialists - they will not only make a detailed project, but also lay communications to the installation site of the furnace.

In addition, you will have to go through the approval process with the management of the gas service and obtain permission from the fire service.

But these actions need to be done only if the furnace will work from the gas line. On gas-balloon equipment, completely different spare parts must be installed, since the fuel will come from cylinders.

When drawing up a project, you need to develop a good ventilation system, which looks like a chimney. This work should also be entrusted to professionals, since with poor ventilation of the room there is a chance of poisoning carbon monoxide if there is a heating failure. Before inviting specialists, it is worth preparing all the permissive documentation - workers have the right to refuse installation if there is no agreement.

Gas oven installation

Before starting the installation of furnace equipment, you need to prepare a reliable and heat-protected base:

on the floor where it is supposed to install the structure, an asbestos sheet is laid;
then it is covered with a piece of sheet iron and screwed tightly to the boards. If the floor in the bath is made of concrete, then these manipulations are not necessary;
then carry out the protection of nearby walls, which are also sheathed with asbestos and iron. Even if the equipment is installed at a considerable distance, it is worth making sure - the heat adversely affects the material of the walls;
now there are special screens on sale that can provide additional protection not only to walls. Experts advise to install them around the stove from the side of the steam room - they will prevent those present in the bath from touching the hot surface.

Further, the installation is carried out in accordance with the gas supply system and the presence of curtain walls in the bath. In the case of installing a furnace that will operate from a gas main, it is worth buying a special metal hose connected to the inlet pipe. The distance is calculated in advance - it is important that there is no strong tension when laying it to the installation site of the furnace equipment. In the walls and partitions, walkways are equipped, which subsequently need to be well insulated so as not to drown the street in winter.

Important! It is undesirable to use a rubber hose for connection, as it is unsafe, and it lasts a short time. It is better not to spare money and buy an element made of heat-resistant and moisture-resistant material. In addition, modern hoses for connecting gas equipment are easy to use and reliable.

If you decide to install bottled equipment with liquefied gas, then you should prepare special room, which will be at a decent distance from the construction of the bath, protected from direct sun rays and summer heat. You can go in two ways - to build a special shed, the walls of which will be additionally insulated with foam plastic or mineral wool.

Dig a pit, the walls of which can be upholstered with a board so that they do not crumble, pour concrete. After installing the cylinders in this recess, they construct an insulated cover, which can then be sprinkled with earth.

Next comes the assembly and connection of the gas furnace. The installation of the structure must be carried out strictly according to the instructions, since different manufacturers have their own specific nuances during assembly - various fasteners and installation methods. But there are rules that apply to all models without exception:

the minimum distance between the wall and the furnace is 30 cm. If the walls are prepared and sewn up with refractory material - 15 cm;
the chimney is discharged through the node on the ceiling and roof;
nail a sheet of metal to the floor in front of the firebox - sparks can fly out of it.

If the gas stove model provides for the installation of a water tank on a pipe, then you can adjust it in height so that it is convenient for all family members to use it.

Once the oven is set to permanent place- start assembling the control system - if it is not built into the structure. In this case, it is tedious to strictly follow the instructions that usually come with the oven.

To date, there are many models that provide for auto-ignition, it does not work without electricity, therefore, before assembling the structure, a separate cable is pulled into the bath, protecting it with a special corrugation from high temperatures.

If there is no built-in fan, then before each ignition it is necessary to check the draft in the structure - for this, a match is lit and brought to the furnace window.

If there is a gas stove in the bath, then the room will completely warm up in winter to the desired temperature after 8 hours. This is not an exact indicator, everything will depend on the power of the structure, the quality of the insulation of the walls, ceiling and floor.

If you install external temperature sensors, the oven will turn off automatically.

Making a stove for a bath with your own hands: instructions

Necessary materials:

gas burner, atmospheric;
gas bottle, which has already worked;
metal door for the combustion chamber;
a used brake disc from a large car - for a heater;
gas pipe with a cross section of 50 mm - for gas supply;
pipe 100 mm - for the chimney.

Manufacturing :

Cut the gas cylinder with a grinder according to the drawing.
Drill 2 holes for gas and air supply with a crown.
Form round parts for partitions that will divide the cylinder into working areas.
Weld the structure by inserting the blanks into the places where it will be located: the firebox, the blower and the heater.

Important! If the water tank is on top, then it is worth welding a pipe to remove smoke.

From a pipe with a cross section of 50 mm, you need to blow. To do this, make several holes with a cross section of 5 mm, weld a pipe section to the main cylinder - in the place where the blower will be located.

Then, in the same order, install the gas supply pipe, which should be opposite the firebox where the burner will stand.

At this stage, the manufacture of the gas stove can be considered complete, it remains only to install the internal equipment.

Finally

If we consider the cost of high-quality, modern gas heating equipment, then it will be equal to the price of laying a heater by an experienced stove-maker. It is practically not necessary to take care of a gas oven, to prepare a large number of solid fuel every year is not necessary, while gas is cheaper. For this reason, more and more ordinary people are switching to gas heating baths, saunas and houses.

As for heating, many owners of private and country houses. The comfort in the house depends on how correctly the heating device and the heating system itself are chosen. To date, the most popular is, simple gas stove home is in high demand. And how effective it will be depends on which gas stove is chosen for heating the house. How these devices look can be seen in the photo.

During the operation of the gas furnace, the grate is heated, and the heat is supplied to the walls of the firebox. This ensures uniform heating of the air. If you install gas burners in the firebox at the lower level, then the lower masonry of the furnace will warm up more efficiently, and accordingly, the volume of the firebox will be used more reasonably.

The firebox of a gas furnace in the upper part borders on chimneys, and in the lower region it communicates with blowers. Through this element, air enters the gas stoves for the home, without which the combustion of fuel becomes impossible.

Flue gases coming under the influence of draft from the firebox give off heat to the chimneys. Gas stoves for the home are designed in such a way that gases pass through channels connected in series. These channels have no more than five smoke turns. Gas stoves are strictly forbidden to be installed in houses in which there is a horizontal arrangement of channels. Like wood-fired boilers, gas appliances should be located some distance from the walls.

Furnace gas heating: types

The power, efficiency, efficiency and safety of the furnace depends on which burner is used. It mixes gas with oxygen.

There are several types of burners depending on the type of power control:

single-stage products (fuel supply is either on or off);
two-stage (the furnace can switch to economy mode, which reduces the heating power);
with floating adjustment (power changes smoothly).

According to the type of air supply burners are:

atmospheric (air is sucked in by means of draft), they do not depend on electricity, but the efficiency does not exceed 90%;
supercharged (air is supplied by a fan when closed cell), they depend on electricity, and the efficiency exceeds 95%.

Also, burners can be either with electric ignition or with pierre ignition. The former depend on electricity, but there is no constantly burning igniter. See also: "".

Gas stove for home: advantages

Using gas ovens for the home has the following advantages:

Ability to operate at any time of the year and day. In heating systems of this type there are no interruptions.
High efficiency . Gas stoves help create a comfortable temperature in the house at any temperature outside, even in severe frost. Unlike solid fuel boilers, gas units do not require a place to store fuel, moreover, natural gas is a relatively cheap fuel.
Ease of operation. Stove gas heating is very convenient in operation, the cost of maintaining the heating system is minimized (read also: "").
Durability. Gas ovens are durable - they last for several decades, so the likelihood that they will fail over the next 10 years is minimized.

Of course, gas units also have some disadvantages, but compared to other heating appliances, there are much fewer of them. The most significant is the high price of gas equipment, but given the low cost of fuel, the acquisition fully pays off over time. If you use stoves that run on other types of fuel, the heating costs will be several times higher.

Installation of gas ovens

Connection gas appliances to a centralized gas pipeline will cost a lot, not all owners of private houses can afford it. Therefore, if the building is not yet connected to the gas main, then it is worth considering other options for creating heating or buying cylinders (more details: ""). If gas is already supplied to the site, then the installation of the heating system will be much cheaper.

After the gas heating unit has been installed in the house, it is necessary to check the operation of the equipment. Any errors during the installation process can adversely affect the comfort in the house and the heating efficiency. Besides, gas equipment if installed incorrectly, it can harm a person - natural gas is a dangerous fuel, and this must not be forgotten. See also: "".

The connection of gas ovens must be carried out by specialists. After that, the correct installation is necessarily checked so that unforeseen situations do not occur when starting the heating equipment.

The gas heating furnace is an efficient, durable and economical device. It does not need regular maintenance, but it is important to properly install it so that the stove is safe and the house is maintained. comfortable temperature without extra fuel costs.

Modern gas stove for home video:

Natural gas can be called the most inexpensive type of fuel. And thanks to this economy, gas stoves are becoming more popular, including when used in baths. Devices that run on gas are very compact and easy to maintain. Today we will look at how to make a gas stove for a bath with your own hands and what you need for this.

Features of gas ovens

Today, a gas stove can seriously compete with a wood stove. In use, it is much cleaner, easier and cheaper. It can quickly warm up the steam room air: in summer for three to four hours, and in winter a little longer. It takes about eight hours for the bath to warm up well. But high-quality heating provides comfort, warmth and coziness.

One of the main advantages of a gas bath, as we have said, is efficiency. This fuel is the cheapest and most economical, so you can save a good amount. Wood and electric stoves will require three times more costs! The gas oven does not require special attention to you. The combustible waste is very small, so the heating box and chimney ducts are practically not polluted.

There are rules for installing a gas boiler in a bath, which are very strict, but ensure high safety of use. The service life is approximately twenty-five years, and if you regularly perform preventive repairs, the furnace will work for a long time and not break. If not taken into account too much strict rules security, only the mandatory presence of a centralized gas pipeline can be attributed to the disadvantages.

Design of gas furnaces

The device of gas stoves is similar to wood stoves, but has some differences in fuel properties. The gas furnace has a housing, a fuse (to cut off the fuel supply in case of attenuation), a thermostat, a sealed gas chamber, and a chimney. The difference lies in the fact that the fuel supply is carried out through a gas pipeline.

Gas cylinders are placed in a special container in accordance with all safety regulations. As practice shows, a gas cartridge of five cubic meters can warm up a room up to two hundred square meters during one heating season. It is worth noting that propane has a higher heat supply capacity when compared to natural gas. Such ovens may different power, the calculation of which depends on the volume of the bath.

You should know that there are 252 kilocalories of heat per 0.4 cubic meters. Therefore, you can easily calculate how much gas you need. Gas sauna stoves do not require periodic heating, so they should be turned off during use. Such furnaces work according to a very simple principle - air is mixed with gas even before it enters the furnace. A separate part of the air passes into the furnace.

You can regulate the amount of air that enters the gas sauna stove with the bottom door, which also allows you to clean the burner. Using a special flexible hose, gas is supplied to the burner (or a cylinder is used).

Classification of gas ovens

There are many different modifications of the gas furnace. You have to determine for yourself what kind of bath you want and, based on this, make a decision. Most a good option- This is a brick oven with an inflatable burner. A simpler option is a metal oven lined with bricks. gas boilers are divided according to their purpose - they can be heating, heating and household. As a rule, heating furnaces are used in baths, which differ in material, water heating technology and type of burner.

Materials for gas sauna stove

Homemade gas stoves for baths can be built from stone, metal or brick. Stone and brick take longer to melt than metal, but also retain heat for a long time. But metal gas furnaces heat up very quickly, but also cool down quickly. It should be noted that metal furnaces are the most compact. They are very easy to install and use. If a metal furnace is lined with brick, outwardly it will not differ from a brick one.

Gas-burners

There are two types of gas burners: atmospheric and inflatable. Atmospheric burners are the simplest and cheapest. Their work does not require an automation system and sophisticated equipment. Gas combustion supports air that enters the combustion chamber through a blower or ash door. Efficiency depends on the amount of air inside the bath, so a small amount of oxygen can lead to problems. There are also inflatable burners, but such equipment is more complex.

The design of such burners depends on a fan that blows air from outside and depends on electric current. The price of gas stoves for a bath with inflatable burners will end up being the highest, since this option is more expensive in terms of electricity consumption, but also more efficient. It is often used in so-called combined stoves, which can be fired not only on gas, but also on other fuels, such as wood.

Water heating methods

There are gas ovens with an already built-in water tank and a remote option. The first option is more convenient, since the water is heated due to the combustion products of the fuel. The chimney must be installed so that it can pass through the heated volume of water. Heating the tank also produces heat that comes from the heater. This option allows you not to clutter up the bath with unnecessary appliances.

As for a gas oven with a remote tank, it is usually placed on the nearest wall or in another room. The two elements are connected by a system of pipes through which hot water passes, which is heated inside the furnace.

Do-it-yourself gas oven for baths

Please note that a permit is required to install a gas stove in a bathhouse. The best combination of humidity and temperature can create a brick oven. It may seem that this option is very difficult to install, but with diligence and compliance with all building technologies, any good owner can handle this task.

Preparatory work

First you need to design everything and choose the most suitable place. As a rule, the stove is placed near a partition or wall, since it must heat the steam room and maintain optimum temperature in the rest room. The main elements of a home-made gas stove: base, chimney (insulated with mineral wool), heater, burner, sheet of fire-resistant material, overlay, control unit.

When creating a stove, you can use the remnants of materials that were not needed during the construction of the bath, but it is better to buy new ones. We recommend that you do not save on quality, because a good oven will provide you with its reliability and durability. In the process of work, you will need the following materials and products: red baked brick, clay, galvanized sheet, reinforcing bar, metal pipe, grate, sand, blower doors, asbestos-cement pipe, firebox doors, water and gas pipe and steel sheet.

Before you make a gas stove for a bath, you need to build a foundation. Its construction begins with a pit, the bottom of which should be located below the freezing of the soil, which takes about seventy centimeters. At the very bottom, its width should be slightly larger than the main recess. This approach will help you avoid extra hassle in case of ground movements. The bottom of the pit must be covered with sand fifteen centimeters thick. The sand is filled with water, soaked and covered with a stone with a broken brick about twenty centimeters.

After that, crushed stone is applied, formwork is made and a reinforced frame is installed. Next, it is necessary to pour concrete, after setting of which the formwork is disassembled, and the surface is covered with tar in several layers. The place that is freed from the boards can be covered with fine gravel with coarse sand. Don't forget to install moisture barrier at the top of the foundation.

Arrangement of the furnace walls

After arranging the foundation, you can start installing the walls. To begin with, a protective wall is made that can protect the bath from possible ignition. It is made of cut brick, which is fastened cement mortar. For a brick bath, it is better to use a sand-clay mortar. As a rule, clay is taken at a depth of at least half a meter of earth.

It is poured with water in a special container for a day and thoroughly mixed. Sand must be cleaned of debris and sieved. After that, sand and clay are mixed in a ratio of 1: 1, then mixed again with the addition of water. When the solution takes on an absolutely even consistency without lumps, construction can begin. It is better to prepare the solution in small batches, as it is spent.

The very first brick laying plays a very important role. A bitumen waterproofing pad is preliminarily placed on the foundation, on which the first layer is placed. All bricks are wetted with water, ideally you need to place the brick in water and wait about ten minutes. When the brick is laid on the mortar, it should be held a little with a construction pick.

Carefully check that the bricks fit snugly together, and the seams are no thicker than five millimeters. The second and subsequent rows are laid in such a way that each brick subsequently overlaps the joint of 2 bricks of the bottom row. Before laying bricks in mortar, builders recommend laying them out dry so you can see the full picture.

Each stage of construction must be coordinated with the drawings of the gas stove for the bath. During the laying of the third row, it is necessary to build in the blower door, which is fixed with galvanized wire or cut strips of steel sheet. In the fourth row there is a well for ash and a grate. For its reliable placement, it is necessary to make recesses and leave room for its expansion (one centimeter is enough).

Hardware installation

The sixth row should complete the installation of the blower door, and the seventh should complete the placement of the grate and the firebox door. Cast iron doors are considered the most durable. In the eighth row, a partition is mounted - the beginning of the chimney. Bricks are stacked up to the fourteenth row, on which channels are placed.

Make an opening in the front wall for a container in which water will be heated and which is installed on the channels. The container is held vertically by the side walls. The fifteenth row is laid out of halves of bricks and placed at an angle. The halves will be the basis for laying the dividing wall. The next three rows are laid in the same way as the first.

At the level of the nineteenth row, you can install a door that releases steam. Thin strips of mild steel are placed between the twentieth and twenty-first row, after which a container is placed for hot water, which is surrounded by fragments of bricks. From the twenty-third row, a chimney is installed, which is selected based on the modification of the furnace. The pipe above the roof should rise at a distance of at least half a meter.

A massive gas boiler for a bath should have a large and heavy pipe, and a small one should be light. Remember that the thickness of the pipe must be at least half the brick. The cross section for the passage of smoke must have the same dimensions. Here it is better to use a solution of lime or cement. Clay composition can wash out the rain, which will lead to destruction.

Final works

After all work is completed, the oven must be plastered. This procedure will improve appearance and provide additional fire protection. Plaster can be made from any solution by adding alabaster to it. You can also use gypsum, but keep in mind that it tends to harden very quickly. A great option for plaster is clay, gypsum and sand mixed together (gypsum can be omitted).

Before plastering, it is necessary to prepare the wall of the stove. It is cleaned from the solidified solution up to one centimeter. After that, it is better to putty. If you are going to heat the bath with liquefied gas, the cylinder should be placed outside. Many bathhouse owners bury gas cylinders a few meters from their location. Recall that liquefied gas has a higher calorific value.

If you are assembling a gas boiler for a bath with your own hands, it is better to give preference to the SABK-8-50S automation system. This system perfectly maintains the set temperature and is familiar to all craftsmen. It is also as safe as possible - due to four degrees of automatic protection.

This automation has the ability to turn off heating equipment when emergency situations: when the flame goes out, if the gas pressure drops below the set point, or if impulse system automation is depressurized. Such a furnace is built from eight to ten days and dried for two weeks. After that, you can begin to gradually melt it, but you should not immediately bring it to a strong heating.

Security questions

In order to properly make a sauna stove, you should study the instructions for a gas sauna stove and strictly follow them. As you know, a gas boiler is an explosive structure. To reduce the risk of fire, it is recommended to adhere to the following rules:

The stove must be at least half a meter away from structures that can catch fire. This distance can be reduced by placing a protective barrier from refractory material(for example, iron). If the wall next to the stove is made of flammable material, a special screen should be installed opposite the door, which has a size of two furnace openings.
When installing the stove and chimney, a stainless steel pipe must be used. Pipes must not be pulled through living quarters. The chimney must be up to five meters from the level of the burner. Don't forget to seal chimney to the oven.
The opening for the burner must have the following dimensions: height from 470 to 550 millimeters, width from 350 to 450 millimeters.
The chimney must be carefully insulated against heat loss. This is done at the point where it passes through the roof and ceiling. The chimney is also insulated.
The refractory base, which is located under the stove, should protrude one hundred millimeters from the edges of the appliance.
The height of the room must be at least two hundred and twenty centimeters. It should be arranged exhaust ventilation and installed a window with a window leaf. All doors must open outward only.
The gas pipeline, according to the scheme of a gas furnace for a bath, is made of copper or steel.
Flexible connections must be integral, resistant to pressure and temperature, marked with the label "gas" and have a diameter of ten millimeters.
If a centralized gas supply is not provided, the removal of combustible products into the atmosphere should be installed.
A metal sheet with a heat-insulating layer at the bottom is laid on the floor in front of the oven.

The gas stove is perfect for baths and saunas. Today, this option is the most convenient and economical. If you decide to make a gas boiler for a bath with your own hands, you should take safety rules seriously and obtain permission from the relevant authorities. Subject to all construction technologies and the relevant operating rules, your furnace will serve for a very long time and uninterruptedly.

Building a stove with your own hands means helping your home warm up faster in cold weather. In addition, this is another point of increasing self-esteem. Folded the stove - increased the level of skill. Upon closer inspection, there is nothing difficult in learning how to lay the stove with your own hands. You can study all the necessary literature and practice as an assistant to one of your friends involved in the oven. And maybe even take lessons from the furnace master.

Gas heating stoves

When building a stove, a real zealous homeowner wants to save money and at the same time build a high-quality stove with maximum efficiency. This opportunity is provided thanks to the gas stove, which significantly saves on fuel and at the same time has a simple masonry. This type of furnace is divided into two categories according to the type of material used: steel and brick (or stone).

A stone gas stove looks almost the same as a real Russian stove.. The only difference lies in the location of the heater in its design - it is located directly above the burner and, when built, is placed in a metal container, and not on concrete or a sheet of steel. A novice stove-maker may not be able to cope with this complexity. Outwardly, it looks like a trough with sides that protect it from water. But such a stove can fit into almost any corner of the design.

More simple are gas metal stoves, which are easy to lift and do not require as many bricks or stones.

True, preference in our country is still given to the traditional Russian stove, especially if it needs to be built in a bathhouse.

What we have at hand

The main charm of building a stove with your own hands is the ability to use the materials that are at hand.

So, what do we need to create at least the simplest gas oven with our own hands?

First of all, this is a gas cylinder of a high degree of strength, but not too large.

A brake disc will be laid at the base of the furnace, which should not have any flaws.

Three pipes will be required, one of which will serve as a chimney (diameter 100mm), the second will supply gas, and the third will become an air duct (these two pipes are 50mm each).

Gas burner: atmospheric type.

Connecting structures with various fittings and other details.

The gas cylinder is cut off from above, thus turning into the main part of the "body" of the future furnace. Moreover, the hole should match in diameter with the brake disc. It is desirable to weld the brake disc itself. It is also possible to fasten it with bolts, however, this type of connection will not guarantee that any foreign object, dust or dirt will not get into the space between the bottom and the disk.

In the gas pipe and air duct, you need to drill a dozen holes of 5 mm each. At the bottom of the cylinder, you need to drill a hole that will be two millimeters larger than the diameter of the pipe. This will include pipes, and outer part will be 20 cm long. All seams must be hot welded, after which the oven can already be painted.

Do-it-yourself heating stove (video)

Of course, during the construction of the furnace, there is a desire to expand its functions from heating to heating and cooking. Such an oven will require simple maintenance, and the benefits from it will be many times greater. This type of oven has several varieties. In particular, a stove by Korobanov and Samarin, an ordinary potbelly stove and a simple Russian stove. Each of these types of stoves has its own requirements for laying. This is a fairly large topic for discussion, so we will only touch on a few important properties this type of stove and the benefits it brings.

The firebox of the stove is, in fact, a stove for cooking, which saves time and fuel.

The heat released during the combustion of gases is used to heat food.

While cooking, you simultaneously warm the room, which is very convenient in cold weather, when additional heat does not hurt.

There are some design features which should also be taken into account.

The volume of the firebox is much smaller than that of other types of furnaces.

The combustion temperature of the fuel is underestimated due to the fact that the firebox is located under the metal flooring.

During operation, a large set of accessories is used, starting with a damper and a valve and continuing this range with other things.

As practice shows, it is these ovens that are the most common in our country, since they are enough - they allow you to heat the room with high quality, and at the same time you can cook food on them. And the design of the Russian stove allows you to equip also a stove bench, which can be used not only as a sleeping place with heating, but also as a place for drying mushrooms, grass and things. It is especially pleasing to the heart to look at the Russian stove, which is a symbol of Russian history and life.
