Gas boiler for saunas and baths: types, characteristics, rules for choosing the best option

Agree, the bathhouse is a sacred place for a Russian person who is treated with special trepidation. However, collecting firewood can be very troublesome and expensive. Therefore, many consider a gas boiler for a sauna to be the best option - an efficient unit that quickly heats up to the desired temperature.

We will tell you about the advantages of a gas boiler, as well as about the features of arranging a gas boiler room in a bath. We will show you what to look for when buying it. As a bonus, we will reveal the secret of obtaining a gasification permit.

Advantages and disadvantages of a gas boiler

Most people living in gasified areas choose a gas boiler for heating a bath or sauna. This decision is economically justified.

Benefits of using gas equipment:

• small heating fee;
• no need to stock up on fuel;
• there is no need for a place to store fuel;
• the need for cleaning from ash and coals disappears;
• there are no processed gases in the room;
• small dimensions and weight at maximum power;
• minimum kindling time;
• safety and ease of use.

A modern gas boiler for arranging your favorite bath or sauna solves several problems at the same time:

• allows you to get rid of carbon monoxide and an unpleasant odor of scale;
• heats the air smoothly and maintains the temperature;
• does not take up much space.

If you entrust the installation of equipment to specialists and do not interfere with the operation of the control unit and burners, then the risk of fire and carbon monoxide poisoning is minimal. This will keep the chimney clean.

The disadvantage is the high cost. In order to correctly connect all the pipes, electronics, power supply, check the operation of the sensors and ensure tightness, you should resort to the help of an experienced master. You will also have to pay for the services of a contractor versed in plumbing, electrical and gas supply.

However, all investments will pay off in a couple of years, since the gas model of the boiler is more profitable than other types of heating equipment.

Types of gas boilers for a bath

All equipment operating on blue fuel is divided into:

• single-circuit - installed in small rooms;
• double-circuit - in addition to heating, they will provide hot sanitary water;
• three-circuit - additionally heat pools or underfloor heating.

In order not only to heat the bath, but also to ensure the flow of hot water, you should choose double-circuit boiler, the power of which is 20-30 kW. This capacity is sufficient for an area of ​​200-250 square meters. Water heating rate - 10-14 l / s.

Boilers can operate both on main gas and on bottled liquefied gas. Not all summer cottages are supplied with gas, so the latter type of boilers is optimal for a private bath. Some models are equipped with replaceable nozzles, which allows the equipment to operate on liquefied and mainstream fuel.

Classification of gas boilers:

• by material - metal, stone, brick;
• depending on the fuel used;
• equipped with different tanks for heating water;
• have different types of burners.

Compared to metal, brick and stone stoves take longer to heat up, but they are able to retain heat longer. A metal boiler is chosen because of its compact size, after which it is covered with bricks.

The burners are atmospheric and inflatable. An atmospheric burner does not require electricity to operate, therefore it is more economical and at the same time completely silent. It functions due to the air entering the blower. The main requirement for boilers with atmospheric burners is well-equipped ventilation.

The inflatable burner differs in that it requires a fan that is powered by electricity. The principle of operation is the same: gas is mixed with air for heating. To make the operation of such a model safer, you need to take care of the emergency power supply device.

How does a gas oven work?

The principle of operation of the equipment is similar to the classic wood-burning stove. The only difference is the type of fuel. Gas boilers have a burner instead of a firewood compartment. The gas mixes with oxygen and produces heat.

In some models, the burners are combined with a firebox for firewood. Design feature:

• gas burner in the housing;
• fuel source;
• in the upper part of the pallet for stones;
• a device for the removal of combustion products;
• thermostat and fuse;
• sealed chamber with recycled fuel.

During the operation of such a boiler, there is no need to put firewood and monitor the temperature. Thanks to the automatic control system, you can not be distracted from the bath procedures.

How do you choose the perfect model?

When choosing a gas boiler for your bath, you should pay attention to:

• coolant volume;
• the area of ​​the heated room;
• installation requirements and the presence of a chimney.

Heating equipment for baths and saunas can be wall, floor, parapet. Floor models are large in size, simple in design and operate in automatic mode. Disadvantage - requires a lot of installation space.

Are more compact in size wall models. They are easy to install and equipped with a forced smoke exhaust. A chimney is not required for parapet boilers.

When choosing a boiler, you should pay attention that the high temperature stability of the heating device is not an indicator of quality. You also need to monitor the gas pressure. This is the main criterion when buying equipment. Disruption of the blue fuel supply can be unsafe.

When choosing a gas boiler, it is important to correctly calculate its power. This indicator depends on the area of ​​the heated room. Requirements for norms - for 0.4 cubic meters, 252 kilocalories are needed. To calculate the power value, you need to substitute your values.

Useful tips for choosing a gas boiler for baths and saunas:

1. The steam room is often small. In order not to "steal" the space with the installed equipment, it is better to opt for a medium-sized model.
2. The best option is a boiler with a remote fuel channel. The advantages are space savings and higher operational safety.
3. The lower the gas consumption, the more efficient the operation of the equipment and the higher its efficiency. The data can be found in the unit's passport.
4. Some boiler models operate only on main blue fuel. This should be taken into account if you plan to use liquefied bottled gas.
5. When planning to impose a brick on the boiler, you need to pay attention to how many stones the power of the unit is designed for.

It is preferable to purchase the boiler from well-known manufacturers. The best domestic producers: Ermak, KUTKIN, Termofor.

Safety and installation requirements

Since gas is used for work, you should be as careful as possible during operation.

Necessary:

• monitor the wear of all equipment parts;
• regularly check the readings of the gas analyzer and other devices;
• entrust the replacement of parts only to a specialist.

Savings in the purchase, installation and operation of gas equipment can lead to dire consequences.

Requirements for the premises where it is planned installation of gas equipment: no high humidity, there should be no accumulation of dust, the access of children is limited.

Before a gas boiler room is equipped in a sauna or bath, you need to study the rules for safe installation:

• the height of the room must be at least 2.2 m;
• all doors must be opened outward;
• vents and exhaust ventilation are required;
• absence of flammable structures near the equipment (minimum distance - 0.5 m);
• if the walls of the room are made of a fire hazardous material, when installing the equipment, indent at least half a meter (use of a fire-resistant barrier or heat-resistant screen);
• a rectangular hole for a burner (height - 48-55 cm, width - 35-45 cm);
• to prevent gas leakage, it is recommended to install a special sensor that will be triggered when the burner goes out;
• the smoke exhaust pipe should not pass through living rooms;
• the oven must have a metal base that will protrude at least 10 cm;
• to exclude the appearance of condensation, the chimney must be made of stainless steel.

If the site is not gasified, then forced removal of combustion products should be organized. To maintain a high temperature, high-quality thermal insulation of the room is necessary.

The best solution would be to use foil insulation. It should be noted that heat loss increases in the presence of windows and non-insulated doors.

Features of gasification of a bath

In the decree of the Russian government of 2008 No. 509 it is said that gasification of the bath room is allowed. The only condition is that it is prohibited to use it for commercial purposes.

The project should include:

• the presence of a separate entrance (heat-resistant materials are used for the manufacture of the door);
• the presence of fire extinguishing and alarm systems;
• the equipment must be of industrial production and have a quality certificate;
• a ventilation system and a carbon monoxide sensor are required.

Practice shows that the chance of obtaining a permit for gasification of a bath increases if all work is done by specialists competently and efficiently. After the building of a bath or sauna is built, it should be registered with the BTI. The next stage is a trip to the UGH of the city, where an application for gasification is written.

When the application is considered, an inspector will visit the gasification site. As a result of the check, it may be necessary to make changes (installation of additional ventilation, alteration of the chimney). When permission is received, all that remains is to connect the equipment and insulate the bath building.

After choosing and installing a gas boiler in the bath, you can enjoy the result of your labor. Money and time costs are offset by maximum comfort and safety. After all, modern equipment allows you to create an optimal balance between temperature and humidity, does not dry out the air and is ideal for lovers of a traditional bath.

Conclusions on the topic

Gas boilers for a bath are more expensive than wood stoves. However, the cost is offset by a host of benefits. You no longer need to deal with the preparation of firewood and monitor the temperature regime in the room. In addition, the gas boiler is easy to operate and completely safe.

The disadvantages of the equipment are too small in comparison with the advantages, so they can be neglected. It is important to observe safety precautions during operation and entrust the installation of the boiler to professionals.
