In the oven, prepare the brooms, wash after going to the steam room. Of course, plunge into cool water is healthier, but warm water in the bath is a must.
Most often, a bath is built in a country house, where there is no way to get hot water through the water supply. You can heat cold water in a boiler or use an oven with a tank.
You can buy a ready-made oven with a capacity or purchase a tank separately.
Bath water tank: purpose and advantages
As already mentioned, the container is used to heat water, which is subsequently used for bathing and various household needs: washing, washing floors, preparing a broom, etc.
The water in the tank increases the humidity in the room, which is especially beneficial and helps to avoid the problem of dry air.
Of course, today there is a huge selection of gas and electric water heaters, but at the same time, bath tanks do not lose their relevance. This is due to their economy: when using a boiler, gas / electricity is spent, but when the water is heated by a stove for a bath, there is, in fact, no consumption at all, because in any case, in order to go to steam, you need to heat the stove. Also, the tank will be irreplaceable in the event that an accident occurs on the gas main or power line, and the use of the water heater becomes temporarily impossible.
How to choose a water tank for a bath?
You can make the tank yourself or buy a ready-made one. If the second option is closer to you, then pay attention to the tips below.
When choosing a container, you need to pay attention to the material from which the tank is made, type, dimensions, etc.
Hot water tanks for a bath: types and their features
In total, there are several types of containers: built-in, hinged, remote and on a pipe. Each of them has its own advantages and disadvantages. Let's consider them in more detail.
- Built-in oven tank
The built-in tank is a classic option. In this case, the tank is installed directly above the firebox, due to this, the water heats up as quickly as possible, and retains heat in the tank for a long time. To pour water, you can make a tap or a top lid over the container.
If you are going to buy a built-in type, then you need to pay attention to the thickness of the walls of the container. It must be more than 0.8 mm. Make sure the seams are tight.
The disadvantage of such a tank is that it cannot be left empty. In addition, boiling water generates heavy steam, which is not always good for a bath, as a result, during steam bath procedures, you have to regularly drain heated water and pour cold water.
A traditional Russian bath has two tanks: one for hot water, the other for cold water. The comfort of relaxation in the bathhouse, as well as the efficiency of water heating, will depend on how correctly you choose the material for making the tank under the water, as well as where you install it. Nothing should be said about the choice and installation features of the cold water tank, because today it can be replaced by connecting a central water supply to the bathhouse. As for the hot water tank in the bath, there are many nuances when choosing and installing it, which we will talk about further!
The purpose of the hot water tank in the bath
Despite the fact that today there are many different options for electric and gas water heaters, the traditional water tank has not lost its popularity. This can be explained by the fact that today summer residents are trying to save on utility costs, because water, gas, electricity now have a decent price. In addition, sometimes there are accidents on the power lines or gas mains, as a result of which the factory water heaters will not be able to function and your rest in the bath will stop, or will not start at all.
The main purpose of the hot water tanks in the bath is to swim after the steam room in heated water, which is poured into. Previously, heated water was used for washing clothes and other household needs. In addition, hot water in the tank, which is installed in the steam room, contributes to a higher humidity in the room, which is especially useful at a low temperature in the bath (if the sensor does not exceed 80 ° C).
Features of choosing a water tank in a bath
There are several basic materials for making bath water tanks: cast iron, stainless steel and ordinary metal.
The most traditional and effective is cast iron water tank... Cast iron has a low thermal conductivity, due to which it keeps the high temperature of the water in the tank longer. Also, cast iron does not corrode, so the water in the cast-iron bath tank will always be clean. The disadvantages of a cast-iron water tank are the huge weight of the empty tank, as well as the fact that today there are practically no manufacturers of cast-iron tanks.
A quality alternative to cast iron is stainless steel... It is most often used now, because the material does not corrode, and the containers themselves can be made in various shapes (cylindrical, box, etc.). It should also be noted that stainless steel tanks for a bath can be made with various design features, which allows you to install the tank both above the stove and next to the firebox (we will talk about this in more detail a little below).
In addition to cast iron and stainless steel, some summer residents use enamelled tank... This type of container is not entirely practical, because enamel is easily beaten off in case of mechanical damage, as a result of which open places immediately succumb to corrosion.
Well, the last, the cheapest version of the bath tank is metal container... It is not recommended to use it, because ordinary metal quickly rusts, which negatively affects the durability of the tank and the purity of the water. We draw your attention to the fact that it is prohibited to paint a metal tank to protect it from moisture. the paint will melt on fire and poison you.
Optimal tank volume
After you decide on the material for making a water tank in a bath, you need to solve the next, important problem - how much tank to choose.
The optimal volume of the water tank in the bath should be calculated on the basis that one adult will need at least 20-25 liters of hot water to relax in the bath. Based on this, if you are going to relax in the bath only with your family (two), you need to purchase a 50-liter container, and if the bath is intended for company relaxation, the tank must have a volume of at least 100 liters.
We draw your attention to the fact that factory tanks have a wide range of volumes, starting from 20 liters and more. Electric ones also come in different volumes, but it is recommended to opt for 60 and 80 liter models.
Options for installing a tank under water in a bath
With the tank sorted out, the last nuance remains - to install it correctly to ensure effective heating. There are three main options for installing a tank under water in a bath: in the firebox, above the stove, and next to.
First option involves the creation of a stove for a bath with a tank mounted in the firebox, which is installed during the laying of the stove (if it is), or welded over the firebox when creating a metal unit.
An important requirement is imposed on the installation of the tank in the furnace of the furnace: the wall thickness of the tank must be more than 0.8 mm. The tank is heated directly above the seat of the flame, which can affect both the base of the container and its ends. Most often, a stainless steel water tank is installed in the firebox.
Second option(installing the tank above the stove with a heater) is also popular. In this case, the tank is installed above, which heats the container. If the tank is cast iron, it is recommended to suspend it from the ceiling with a special hook with a rope, because the large weight of the cast-iron tank can crush the structure of the heater. It is very effective to install the water tank above the stove around the chimney. In this case, the tank will be heated not only from stones, but also from, which also has a high temperature.
Well last option involves installing a hot water tank at a distance from the stove. Most often, this type of tank installation is used in. This is due to the fact that saunas have a higher temperature in the steam room (about 120 ° C), at which a low humidity should be observed. If the water tank is installed in the steam room of the sauna, this requirement will not be fulfilled. That is why the tank is installed next to it, no further than 2.5 meters from the heating source. Heating is carried out using a special heat exchanger, from which two circuits are brought out: with cold and hot water. Cold water enters the heat exchanger, heats up and is spontaneously displaced into the tank, after which the cycle is repeated until the water is fully heated.
That's all we wanted to tell you about bath water tanks. We also recommend that you read the article:!
It is difficult to imagine a traditional sauna without hot steam, a fragrant broom and a warm shower after bath procedures. To organize hot water supply in a bath, the main heat source is often used - an electric or wood-burning stove.
An alternative option is a bath water tank, which is mounted on a heating boiler or stove. Further, how to correctly choose a device of suitable volume and configuration for a private sauna or bath.
How to choose a water tank
The water tank is a special welded structure made of modern materials, equipped with an inlet for cold water and a shut-off and distribution type fittings for hot water.
To choose the right tank for the bath, it is worth deciding on the main parameters of the heater:
- type;
- material of manufacture;
- volume;
- installation method.
First, you need to provide for the principle of water intake, choose the appropriate size and method of installation of the tank, so as not to spend an additional amount on re-equipment of equipment in the future. The thickness of the walls of the structure depends on the size of the tank, which can be from 1 to 1.5 mm.
Next, you need to choose the method of heating the water - with a stove or a built-in heating element. To determine which capacity will be more profitable to install, it is necessary to take into account the total number of visitors for whom the bath is designed.
If the bathhouse can accommodate no more than 2 people, then a device with a capacity of 50 liters is sufficient. For large companies, it is preferable to choose a tank with a capacity of 100 liters or more.
The material of manufacture and design features of the device should be considered when purchasing.
Varieties of water tanks for a bath
There are three types of water tank - built-in, remote or pipe-mounted. Moreover, each has positive and negative sides.
Built-in constructions
The built-in tank is a classic version of the design installed on the bottom of the heating furnace and combined with the combustion compartment at the top.
This ensures accelerated heating and maintaining the optimal water temperature for a long time.
In this case, the bottom of the tank is in direct contact with an open fire, and the liquid is drawn from the tank from above or through a built-in tap.
Remote structures
A portable tank is provided for a furnace equipped with a heat exchanger. A similar device is connected to the heat exchanger using copper pipes, therefore it can be installed in any room of the bath - washing or dressing room.
Among the advantages of a remote-type water tank, one can single out the maintenance of a high temperature of water heating, reliability and practicality.
The principle of operation of the device is quite simple: cold water enters the heat exchanger, and the heated liquid is fed back to the tank.
Pipe structures
The design of a tank installed on a pipe is quite relevant in the case when the bath is used throughout the day.
Such a device provides rapid heating of water to a comfortable temperature due to the thermal energy that is released through the chimney.
Materials for making tanks
The type of material used for the manufacture of a bath tub determines the durability and reliability of the structure, the rate of heating and cooling of the liquid. Water heating devices are made of stainless steel, cast iron and metal.
Stainless steel
The most demanded material for the manufacture of tanks for heating water in a bath is stainless steel. It is resistant to corrosion, fire, high humidity, deformation and damage.
In addition, stainless steel products have high thermal conductivity, hygiene and resistance to temperature extremes.
The stainless steel tank can be presented in cylindrical and rectangular shapes.
Proper care of stainless steel products guarantees efficient performance and a long service life.
Cast iron
Cast iron remains the traditional material for the manufacture of water tanks. It has good performance characteristics - low thermal conductivity, resistance to corrosion, deformation, mold formation and overheating.
The disadvantages of cast iron products include the impressive weight and complexity of installation.
In cast-iron tanks, water heats up slowly, but also cools down for a long time. Therefore, one volume is sufficient to meet the hot water needs of the whole day.
Made of metal
The cheapest option is metal tanks, which are susceptible to corrosion, decay and deformation. Such characteristics can negatively affect the quality of water and the durability of the product.
It is strictly forbidden to paint metal devices with moisture-resistant paint, which, when heated, can release toxic substances.
Less popular are enamelled tanks, which are sensitive to mechanical damage. It is not recommended to use such devices in the presence of chips of enamel. To protect the heaters from possible corrosion, their surface is treated with a special heat-resistant compound.
The most practical and reliable are the remote-type stainless steel tanks. Such designs are distinguished by their attractive appearance and operational safety.
Choosing the optimal tank volume
An equally important task is to determine the appropriate tank volume. The calculation of this parameter should be carried out taking into account the rate of water consumption per one adult for bathing procedures, which is from 18 to 26 liters of water.
For a family of 2, it is enough to purchase a tank of 50 liters, for a company of 4 to 6 people - a tank of 100 liters.
Factory models of water heating devices are presented in a wide range of volumes - from 20 to 200 liters. Electric boilers also have different volumes - from 30 to 100 liters.
Water tank installation methods
Having decided on the type and material of manufacture, you can consider the available methods for installing devices that provide fast and efficient heating of water.
The hot water tank can be installed with your own hands in the firebox, above the stove and next to the stove.
Installation in the combustion chamber
The method provides for the use of a sauna stove with an overall combustion chamber for internal installation of a water tank.
The following requirements are imposed on a device for heating water: minimum wall thickness - 0.8 mm, resistance to temperature extremes and deformations.
The structure is heated over an open fire, therefore it can capture its base and end elements. This method is often recommended for installing stainless steel tanks.
Installation above the heater
An equally popular option, which provides for the installation of a heater above the compartment for heating bath stones and steam generation.
If a cast iron device is used, it must be suspended from the ceiling structure with metal cables and hooks. The best option is a lightweight stainless steel tank.
It is economical to install a water heater above the stove around the chimney, which can provide faster heating of water from stones and chimney.
Installation near the stove
This method involves mounting the tank near the heating equipment. As a rule, it is used in saunas with high air heating temperatures and low humidity.
In this case, the hot water tank is mounted at a distance of at least 250 cm from the direct heat source, and the water itself is heated using a double-circuit heat exchanger with cold water supply and hot water outlet.
Cold water is supplied to the heat exchanger and heats up, then it is removed to the heater, after which the heating cycle is repeated.
Method of heating water by heating element or stove
What is more economical for heating water - to heat a sauna stove or install heating elements?
This is determined by the duration of the visitors' stay in the bath during the treatment.
For example, if a tank of 35 to 60 liters is sufficient for a steam, then a large company requires at least 120 liters.
At the same time, the wall thickness affects the rate of water heating: for devices of 50 liters - from 0.8 to 1 mm, for products over 100 liters - from 1 to 1.5 mm.
For a washing compartment with plumbing devices - a shower and a tap - it is recommended to install a closed-type hot water supply system: the heat exchanger is mounted in the stove, a water tank is connected to it. For a small room, a structure installed above the heating equipment is suitable.
Competent combination of a bath stove and a water tank allows you to create a reliable and practical design that will provide not only quick heating of the premises, but also hot water supply. The choice of a suitable tank for heating water is carried out taking into account the design and operational features of the bath.
A tub for a bath on a pipe is a kind of stove-stove, familiar from old films. Hot water when taking a bath procedure is a natural attribute, which means that in the absence of central water supply, it needs to be heated. At the same time, the chimney in the bath is designed to throw out hot smoke from the firebox. Thus, significant heat energy is wasted away. A water tank on a pipe for a bath allows you to combine these two processes, and the chimney begins to do useful and necessary work.
Sauna tank on the pipe helps to save space in the sauna
Process features
The chimney is an indispensable element of the sauna stove, through which the products of fuel combustion (smoke) are removed and the necessary draft is provided to maintain combustion in the furnace. The smoke rising through this pipe heats it up to a temperature of more than 450-500 degrees, which makes it necessary to take measures to isolate the chimney from the elements of the bath structure.
For a long time, the question has arisen of how to use the removed heat with benefit. When carrying out bath procedures, you need hot water for washing after visiting the steam room. For these purposes, there is always a container (tank), which provides the required volume of water.
Nuance! Using the heat from the chimney is considered to be an efficient and economical way to heat it up. In principle, the issue is resolved when placing the tank at the top of the chimney pipe or when heating the coolant with the help of smoke heat.
The water tank installed on the pipe effectively saves heat from the smoke exhaust, due to this it heats the water What is the advantage of a tank on a pipe? The following positive aspects can be highlighted:
- warming up is fast and does not require additional fuel;
- the high temperature in the tank is automatically maintained throughout the entire time of the furnace firing;
- the tank-pipe at the sauna stoves can have a significant volume, because there is a possibility of using the chimney along its entire length.
Chimney tanks can be of various lengths and designs What designs can be used
You can place the tank in the bath in different ways. The following varieties are mainly used:
- Built-in design. In this case, the flue pipe runs inside the tank. This design is considered stationary, non-removable and is installed during the manufacture of the chimney. The tank can be made in the form of a pipe (cylindrical version) or have a rectangular section. It is important to securely seal the bottom pipe inlet to prevent water seeping out of the tank. To use water, outlets are made from the tank directly to the shower stall or intermediate tank. Given the elevated location of such a tank, water flows by gravity.
- Suspended construction. This system is removable, i.e. installed on an already operating chimney. The tank is placed close to the chimney and is securely attached to the column. Such containers can be purchased or made by hand. Such a design is characteristic when a gutter is formed on the rear wall, repeating the shape and diameter of the chimney, which makes it possible to bring the surfaces as close as possible and ensure high-quality heating.
- External design. In principle, the water tank itself can be placed in any convenient place (for example, in a shower room). In this case, the energy of the chimney heats up the coolant, which is directed to heat the container with water. When such a heat exchanger is mounted on a bath tube, the installation height of the tank should be chosen so that the gravity of the coolant is ensured according to the laws of physics, i.e. a warm stream rushes up, and a cooled one - down. This design provides for the presence of additional elements in the form of a heat exchanger, but it allows the tank itself to be placed in the right place.
Scheme of water circulation with a remote design of the tank and stove in the bath Depending on the design, the tank can be placed at different heights. 3 options can be implemented:
- At oven level: The base of the tank is placed on top of the oven, which means no additional brackets are required. The main disadvantage is that the height does not allow for the gravity of water for taking a shower. In this case, it is scooped up by hand.
- On the chimney column. This design is located at a certain height, which eliminates the previous disadvantage. Mounting the tank requires special brackets, and the weight of the structure is limited.
- At the attic level. Here for the tank there is a reliable support in the form of a ceiling slab. The problem arises in a cold attic, where you have to think about external thermal insulation.
Attention! An important parameter that determines the choice of a tank is its volume, it must be sufficient for a full-fledged washing process.
When calculating the parameter, they usually proceed from the following need: 10 liters per person for a bath procedure and 5 liters per person for taking a shower. In addition, a contingency reserve should be created.
There are various forms of water tanks for a bath on the chimney The dimensions of the container also depend on the design and dimensions of the chimney. The most common is a typical bath tub for a 115 mm pipe. Naturally, a bath tank for a pipe of 150 mm is made of a larger diameter, regardless of need.
The choice of the volume of the metal water tank depends on the number of family members 
What materials are used
The bath tank is made of metal, but a specific material is selected taking into account financial capabilities, volume and heating characteristics. The most popular are the following designs:
- Cast iron. The main advantages: high strength, durability, while the water temperature remains for a long time after stopping the furnace. At the same time, the cast-iron container heats up slowly, and most importantly, it has a large mass, which requires reliable support when installing the structure.
- Steel. The cheapest and most affordable material used in economy structures. The water in the steel tank heats up quickly, but also quickly and cools after stopping the fire. The most important disadvantage is corrosive destruction, which requires protective covers. One of the common options for eliminating this disadvantage is the use of enamelled tanks. However, when choosing this material, it should be borne in mind that with local damage to the enamel, accelerated corrosion begins in the focus of damage.
- Stainless steel. A tank for a stainless steel bath pipe is considered the most common design, because optimally combines cost and durability. The material is more expensive than ordinary steel, but does not corrode and has a long service life. At the same time, the stainless steel lends itself to welding, and the tank from it can be made with your own hands.
The remote design of the tank is in more gentle conditions. Extreme temperature (400-500 degrees) affects only the heat exchanger located on the chimney. The walls of the tank itself do not heat up above 70-80 degrees, which means that it can be made from different materials. In addition, it is usually placed on a wall where the risk of damage is reduced. In such conditions, decorated enamel containers become very popular. The supply pipes for the external tank in the bath can be made of metal, composite material and heat-resistant plastic. It is important to ensure their thermal insulation.
The easiest and most affordable way to make a bath tank is the built-in version, when it is hung on the chimney. Such a system is not in vain called samovar in everyday life, because it uses the same principle, i.e. heating the water with hot smoke rising through the inner pipe. Such a tank is mounted during the construction of the furnace or installed by dismantling the chimney section.
In the selected place, a pipe is attached to the brackets, and so that the gap between the outer diameter of the chimney and the inner body of the tank pipe provides the required volume. In the lower part of the tank body, the base is welded, and all gaps are sealed with a heat-resistant sealant. To remove water, a tap with a tap is welded (Fig. 1). The top of the tank is closed with a lid.
Fig. 1 Installation diagram of the bath tank In principle, the body of the tank can also be made in a rectangular shape of the desired capacity. The wall thickness is selected taking into account the volume. For the manufacture of a small tank with a volume of about 50-55 liters, you can use a metal sheet with a thickness of 0.9-1.2 mm, and for a capacity of more than 70-80 liters, you will have to use metal with a thickness of at least 1.5 mm.
If the water supply is suitable for the bath, then the external system is more suitable. It is shown in fig. 1. In this case, a coil is mounted on the chimney. The outlet of hot water in the direction of the external tank is carried out from above, and the return of the coolant, respectively, from below. During installation, it is necessary to install the necessary shut-off equipment (valves, taps, valves).
Note! Particular attention is paid to the sealing of all joints, for which a special heat-resistant sealant should be used.
When installing a tank in a bathhouse on a chimney pipe, you will need the following tools and equipment: a welding machine and electrodes with a diameter of 2.5-3 mm, a grinder, a hacksaw for metal, an electric drill, a puncher, a hammer, pliers, a set of keys, a vernier caliper, a tape measure.
The bath tank on the chimney pipe allows you to have a supply of hot water without unnecessary fuel consumption.
Such a system uses the energy of uselessly escaping smoke, which has significant economic benefits. A system of different designs can be made and assembled by hand.
People planning to build a bath with their own hands sooner or later face the problem of heating water. Of course, you don't have to think about it at all, simply by installing a large barrel in the steam room, because this is exactly how our ancestors once did. In winter, they poured snow into the barrel, after which they washed themselves with heated melt water. However, progress, as you know, does not stand still, and it is better not to wash yourself with snow collected from big cities - the environmental conditions are not entirely suitable. Therefore, many resort to a safer option - they install tanks on a pipe for a bath. The types of these tanks, approximate prices and installation features will be discussed in today's article.
Factory bath tanks (per pipe). Average prices
The oven with the described tank is sold today in almost any store. Such devices are not only economical, but also extremely simple in terms of operation, moreover, even models with several operating modes are now being produced. The user, for example, can adjust the heating time of the steam room, the process of burning wood, and even the density of the generated steam.
Installing such ovens is extremely easy. They do not need a special foundation, they weigh a little, and the tank can be positioned anywhere. Factory products are produced in the widest range, so you can choose for yourself the option that best suits the planning of the premises.
Note! In order for such ovens to serve as long as possible, you need to ensure that the tank is filled before heating. If the outside temperature is below zero, then after the bath procedures, the water should be drained.
Now let's get acquainted with several popular models, as well as find out their average market value.
Table # 1. Average prices of water tanks
As you can see, regardless of the type of container, almost all of them are made of "stainless steel". They are relatively cheap, a small product can be bought even for 2 thousand rubles.
Varieties of cisterns for a bath with installation on a pipe
Today, there are several options at once, thanks to which you can make bath procedures simpler and more convenient. Let's make a reservation right away that a water heater can be installed in the washing room and cold water can be supplied to it. However, there is no point in wasting electrical energy, because the bath will still be heated in any case. In order for people to be washed to be provided with hot water, you need to install a tank in which it will be heated.
There are several classifications of such tanks, let's take a brief look at each of them. So, according to their location, the tanks can be of three types.
Note! If you prefer the third option, then select a large tank, since the heating element can be used along its entire length. This tank can lead along the chimney to the ceiling, and in some cases even cover part of the attic space.
A lot depends on the material used in the production of the tank. This can include the time during which the water remains warm, and the rate of heating itself, and even the operating life of the container. Today tanks are made from three main materials.
Finally, tanks are also classified according to their volume. It is believed that 10 liters of heated water is enough to wash one visitor in the bath. And in order to calculate how much volume of the tank you need, you need to take the total number of people who will be steaming, and multiply it by 10. As a result, you can find out the required volume.
However, there are several factors to consider.
- With a low power of the heater and a large area of the steam room, the water will not have time to properly warm up.
- And if the tank is too small, it will quickly evaporate.
In other words, when choosing the required volume, it is necessary to take into account all aspects and opt for an option that satisfies all conditions.
About the strengths and weaknesses of the design
A samovar system means a stainless steel bathtub on a pipe (or any other material). He is the main element of the chimney elbow. Its placement is more comfortable, and the water warms up more intensively and evenly than in the case of the other two installation options. In addition, the system itself is more compact.
As for the weaknesses of such structures, they include the fact that these tanks are not very convenient to fill with water. Although this problem can be easily solved if you install the upper part in the attic, or, alternatively, run a water tap to it.
Note! The slightest miscalculations in planning the volume of the tank are very dangerous, because the water as a result can boil very often.
As a rule, people prefer those tanks that are made of stainless steel. If other materials are used, corrosion may develop, which over time will adversely affect the functionality of the bath. In short, the right decision is to use a stainless steel container. Due to the high thermal conductivity of this metal, heating will be carried out extremely quickly; it is also durable, so it is not afraid of deformation and thermal effects.

Features of installation and connection
So, we found out that the best option is a stainless steel bath tub for a pipe. But many will probably ask the question: which is more profitable - to use a heating element for heating, or to warm it up by means of a furnace? The answer depends on the number of people who will simultaneously take water procedures and how quickly the water should be heated.
If we are talking, say, only about one person, then a tank with a volume of 50 liters is enough for him, but for a company - at least 70 liters. And the speed at which the tank will heat up depends on the thickness of the metal - the larger it is, the more time it will take to warm up and, accordingly, the weight will be greater. So, the wall thickness of a 50 liter tank is on average 1 mm, for large containers it can be 1.5 mm.
But how do you put this tank? First of all, if a tap is used for water supply (in other words, under permanent pressure), then a closed-type water supply will be required. The best option would be a heating device, inside which there is a coil, and to the latter, therefore, a tank is connected.
Although a slightly different option is quite possible: hang the tank on the stove. For this purpose, you can use the simplest product, the volume of which ranges from 50 liters to 120 liters; you can do it yourself. The best option is a container of 80 liters - these are sold in many specialized stores.
If the tank is connected as needed, the system will function as follows: the water in the coil heats up, and then rises into the container. There it begins to cool down, and therefore sinks back into the coil. Obviously, there is a natural circulation, in order to improve which it is recommended to take water from the "return", which is not convenient in all cases, since you have to wait a long time for the tank to heat up.
However, the water itself can be used after the oven has been heated. However, the efficiency of the system will be higher if it provides for the possibility of switching the water intake from supply to "return" (here it is more convenient for someone). If there is an inlet / outlet at the bottom of the tank, the liquid will circulate much more slowly.
The installation procedure itself will look something like this.
Stage one... First, the tank is placed in a double room (more precisely, under the shelves), after which it is connected to the coil through pipes.
Stage two... The upper outlet of the tank will be joined with the same outlet of the coil, while the lower - with the same lower one. All this is necessary to ensure normal circulation. It turns out that cold water will be removed from the bottom, and heated - from above.
Stage three... A special valve is mounted at the inlet for cold water (it is also known as a blaster).
Stage four... According to the instructions of the manufacturer of the tank, pressure is put on the pipe for the bath, upon reaching which this valve will be triggered.
The finished system will function as follows: the container into which water has been poured will begin to heat up by means of a coil, and when heated water is consumed, cold water will be added thanks to a special supply. During the heating of the liquid, if it is not yet in use, the pressure indicator will increase, and when the limit is reached, the valve is activated. As a result, the pressure is released.
Note! If everything is done correctly, then the bath will be fully provided with the required volume of heated water, and the pressure will be just such that it would be convenient for people to wash after visiting the steam room.
How to build a stove with a tank with your own hands?
As noted above, such a stove can be purchased ready-made, but many bath fans make such a device with their own hands. This, by the way, is not difficult, especially since everything you need for manufacturing is sold in the same stores. Now we will tell you exactly how such ovens with tanks are made.
Stage one... You should start by preparing all the required parts. The main part is a pipe, the thickness of which is 50 cm and the length is 150 cm. The pipe should be cut into two parts - 90 cm long (for the combustion chamber) and 60 cm (for the tank).
Stage two... Next, a stove is made from the pipe. To do this, a rectangular hole 5x20 cm is made in its lower part, which will serve as a blower, then a steel plate 1.2 cm thick is welded above it. A grate is placed in the blower and carefully fixed.
Stage three... The remains of the pipe will be a niche for the door and the combustion chamber, so a latch is attached here. A piece of pipe about 35 cm long is welded above the combustion chamber - it will be a heater. In this case, it should be taken into account that the distance between the upper part and the bottom must be at least 10 cm. At the end, the rear part is welded and a door is constructed.
Stage four... Kamenka on? filled with pebbles, after which a steel bar is welded - it will prevent the contents from spilling out. On top of the structure, a coupling made of steel bus is attached. This rail will in parallel serve as the base for the water tank.
Stage five... A steel circle 0.8 cm thick is welded to the end of the container, a hole is made in it for the chimney. The bottom of the pipe must be welded to the bottom to prevent moisture penetration into the combustion chamber.
Stage six... The upper part of the tank must be closed with a semicircle made of steel, and a chimney must be welded to the hole. There should be a hole at the top through which water can be poured. Additionally, a lid with a handle is produced.
That's it, the homemade oven is almost ready! For more information, see the video below.
