How to supply gas to a bathhouse from home: the subtleties of bathhouse gasification

There are quite a lot of modern ways to heat a home sauna built near the house, from using electricity to extracting steam from the central line. Heating a bathhouse is quite expensive, but often there is simply no other choice. The only economically viable option is to supply gas to the bathhouse from home. Experts say that the gain on the financial side of the issue is up to 40%, although in fact gasification does not always turn out to be so profitable.

Installation work and gas laying can only be carried out by companies with a license for gasification of private households

Is it possible to supply gas to the bathhouse?

Technologically, laying a gas pipe does not present any difficulties. Even if you need to pipe gas from the house to a bathhouse located at a great distance from the main building. Using gas main fuel in the sauna boiler room will only improve the level of comfort. Another thing is that gasification of bathhouse heating is always subject to many conditions and restrictions. Therefore, it is worth at least taking a closer look at the condition of the house and the construction of the bathhouse, since strict gas workers and inspectors-controllers will check compliance with the requirements of SNiPs and GOSTs for gas “live”.

What can prevent gas from flowing into the bathhouse:

• Unregistered sauna building. Gas cannot be supplied to a bathhouse that lacks ownership documents, commissioning certificates, and confirmation of compliance with building and fire regulations;
• The layout of the bathhouse does not allow the installation of heating equipment on gas;
• The steam room, where a heater or stove with gas burners will be installed, does not meet fire safety standards, there is no chimney;
• Economic feasibility of using gas for space heating and heating.

It is clear that the structure of the bathhouse needs to be registered and changes must be made to the existing design of a private house. You will have to talk with many officials, including the gas service and fire inspectorate, the Ministry of Emergency Situations. Most of the necessary information about the conditions for gasification of a bathhouse can be obtained from representatives of these services.

Advice! Any expert advice should be checked, especially when it comes to introducing gas into a room or an extension. You can often hear slightly distorted information, so it is best to check the requirements of regulatory documentation, at least with the standards of SP 62.13330.2011 *, clauses 7.1-7.17.

The bathhouse box will need to be thoroughly insulated before connecting gas, otherwise the energy consumption class will be low. Experts may include a requirement for modernization of thermal insulation in the gasification specifications.

Conclusion

If you decide to make a modern steam room with an attractive setting, then a gas stove will be an excellent choice. A sauna is a place where a person relaxes from everyday life, so the heating system in it should not disappoint or work incorrectly. This is why it is important to choose a high-quality firebox for your steam room. According to many experts, gas furnaces are considered the most efficient and economical.

You need to make your choice responsibly, so before purchasing a certain model, consider its competitors and highlight their advantages and disadvantages. This way you can settle on the best model.

Is it beneficial to use gas in a sauna?

Oddly enough, this is the most difficult issue, requiring a balanced decision before starting the process of installing gas into the bathhouse box. On average, the estimate for gasification of a bathhouse with an area of ​​20 m2 will be at least 70-90 thousand rubles. Another 20 thousand rubles. will need to be spent on the project and obtaining permits, especially if the bathhouse has a stone stove with a burner and automation.

The electric option for heating a bathhouse will cost 10 thousand rubles. If you use the steam room at least 4-5 times a month, then the payback period for the funds invested in the gasification of the bathhouse will be at least 12 years. During this time, you will need to replace the heating boiler in the bathhouse and check the meter.

Gasification of a sauna is beneficial only in two cases:

• For very large rooms, with a total area of ​​at least 50 -60 m2;
• For a bathhouse attached to a house with gas already supplied;
• If the climate is severe enough, and in winter frosts reach 30-35°C.

In a country house, the power of the electrical networks will not allow heating the bathhouse with electricity. It makes no sense to completely switch your home to electric heating for the sake of a bathhouse. For an attached bathhouse, the costs of the project and the supply of gas to the heating devices inside the steam room are significantly reduced.

In the last point, the use of gas in the bathhouse is partly a forced decision, since it is quite difficult to warm up the entire building using only electric heaters in severe frost. The process of preparing and heating the bath will take 5-6 hours, while a gas stove heats the steam room in an hour and a half.

Semi-legal gasification, advantages and consequences

Often, the owners of a new bathhouse do not bother registering the premises, but simply lay a polypropylene pipe from the house to the sauna premises in the ground, to a depth of 60-70 cm. It is believed that this is enough to avoid mechanical damage to the main line.

The presence of gas heating in an attached bathhouse is easily established even with an external inspection

The economic side of the issue is clear; such gasification is profitable. Another thing is that the illegal use of gas in a bathhouse can be detected by a fire inspector, and then the standard fine is 50 thousand rubles. it won't be possible to get by. The basis for an inspection can be anything, a complaint from neighbors or planned activities of the Ministry of Emergency Situations with the Ministry of Internal Affairs.

Gasification of a bath with fuel in cylinders or a gas holder

You can also provide gas heating for your bathhouse in another way. For example, install one or more propane-butane cylinders. For gasification, you just need to make a project and register the container itself for liquefied gas.

According to the estimate, this will cost 10-12 thousand rubles with the purchase of a ramp or box for storing the container. In general, this scheme turns out to be more profitable than gasifying a bathhouse with household gas. For a stove-heater with a power of 8 kW/h, the gas consumption will be 1.5-2 l/h; to take a steam bath, it will take about 1/2 of a cylinder in one visit.

That is, for a month you will need to fill two 50 liter cylinders with gas, this will amount to approximately 2.5 thousand rubles. An equivalent amount of household gas of 100 m3 will cost 500 rubles. The overpayment will be 2000 rubles. In total, gasification of a bathhouse with centralized main gas will pay for itself in at least 50-60 months.

Principle of operation

The design of the gas firebox includes such parts as a thermostat, a gas chamber, a system for automatically canceling the gas supply when the fire dies out, as well as a chimney for the exit of waste products.

In itself, the operating principle of this device is based on the mixing of gas and air, which, after combining, allow the fire to gain increased efficiency and fire efficiency. This mixing is adjusted through the boiler door, and the burners are cleaned through it.

It is important to understand that the efficiency and quality of burners directly depends on what gas is used for the fire. Propane allows you to increase the efficiency of the furnace, while natural gas is less efficient, several times according to scientific research.

Gasification of baths: rules

When planning a gas connection, you will need to once again measure the main parameters of the bathhouse premises and make sure that gas equipment can be installed.

The minimum requirements for gasification are:

• The construction of a bathhouse is classified as residential premises, that is, it is an attached structure to the house, which is an integral part of it;
• Inside the bathhouse there is a separate room with an area of ​​at least 3 m2 and a ceiling height of 270 cm with a tiled or concrete floor;
• The humidity level and temperature inside correspond to the standards for residential premises;
• The room has natural exhaust ventilation and a window with an area of ​​0.8 m2.
• Usually, a dressing room is chosen to install a gas stove-heater, provided that it is a separate room that is not connected to a relaxation room, steam room or washing department.

All details of the premises for the proposed gasification with dimensions will need to be depicted on a sketch to scale according to the rules for drawing building structures. The drawing will be useful in communicating with gas service specialists and will help assess the objectivity and legitimacy of their requirements.

Required documents

The main task is to obtain approval to make changes to an existing home gasification project. The decision is made on the basis of a survey carried out by an expert from the Gas Management Department.

You will have to personally visit the UGC in order to take a sample application, and at the same time a list of documents. At a minimum, the package of documents for gas workers will include the following:

• An application requesting changes to an existing project, indicating details, including a description of the equipment consuming gas;
• We are enclosing certified copies of documents from the old project for gasification of the house, and we will also attach a sketch or drawing of the future distribution of pipes for gas. Separately, you will need to make an extract from the register confirming the fact of registration of the bathhouse;
• Application for the issuance of technical conditions for drawing up a gasification project for a bathhouse;
• Application for an expert to inspect the house and bathhouse to determine whether the premises are suitable for the installation and operation of gas equipment;
• Attached are copies of the passport and certificate for the gas stove, boiler or convector used in the bathhouse;
• Additionally, you will have to attach copies of your documents and receipts for payment for UGC services.

In theory, everything looks beautiful, but the fact of submitting documents does not mean that this approval will be received. Perhaps UGKh officials will recommend turning to a private intermediary company with the issue of gasifying a bathhouse, which will process all the documents for an additional 20 thousand rubles. As a rule, a visit to the manager eliminates such gasification issues.

After receiving the technical conditions, the bathhouse is inspected by a UGH specialist, a report is drawn up describing the premises, with a sketch attached. The technical conditions issued for gas installation are considered valid for six months.

It is best to consider the possibility of connecting a bathhouse to gas at the stage of drawing up a gasification project for the entire household.

Gasification methods

There are several ways to provide a sauna with gas:

• Lay a pipe from the house to the bathhouse in the ground, while the gas line can be either metal or polypropylene;
• Perform air installation of the main; this is the most common and most expensive gasification option. Laying a pipe usually takes ¼ of the entire estimate for laying gas;
• Install a ramp with three cylinders in a separate room of the bathhouse or even outdoors in an equipped box;
• Equip a gas holder gas supply for your home and bathhouse.

The latter case can be considered the most convenient, but the cost of such gasification will exceed the cost of laying gas from a centralized supply pipe. If the house already has gas, no one will interfere with gasifying the bathhouse using a gas holder. A huge advantage of a gas holder is the quick completion of work. That is, the contractor company will complete the project, approve the gas tank, install the tank underground and connect the gas equipment of the bathhouse in literally three to four days. She will also fill the gas into a 3-5 thousand liter tank. This is enough for several years of using the bathhouse.

Popular models

The range of sauna stoves is huge, but it is difficult to figure out which manufacturer makes the most effective models at a low price. Let's look at the 6 most popular models:

1. Termofor Taimyr is the most popular model, heats a volume of 18 cubic meters (power 32 kW), has a wall-mounted design, price from 16 thousand rubles;

2. Termofor Urengoy - a wall-mounted structure capable of heating small Russian baths with a volume of 12 cubic meters, price from 15 thousand rubles;

3. Zharstal Sinara Meteorite 2014 - a steel wall-mounted stove for a steam room, capable of heating a room up to 18 cubic meters, price from 14 thousand rubles;

4. Hummingbird convection is an excellent option that can work for a long time in small rooms with a volume of 9 cubic meters, the price is about 15 thousand rubles;

5. Heat Standardgas - a powerful stove (30 kW) with low consumption and an economical mode, capable of heating baths measuring 24 cubic meters, the price is quite low - from 8 thousand rubles;

6. Heat Supergas is a firebox with an increased level of safety even during long-term operation, capable of heating a room with a volume of 24 cubic meters, a chimney diameter of 13.3 centimeters, the price of this system starts from 9 thousand rubles.

Bathhouse gasification project

Project documentation is made either by UGH specialists or private firms licensed for this type of activity. The project will consist of four parts, two appendices, a specification and detailing. There will be a separate agreement sheet with the fire inspectorate.

The first part of the project describes the connection and installation diagram of the pipe, its position and cross-section, starting from the place where gas is supplied to the house and to the point of entry into the bathhouse. The second part describes the wiring inside the bathhouse with a diagram of the pipeline laying, determining the installation locations of each gas consumption point.

In the gas connection project, everything must be written down to the smallest detail.

The third part concerns shut-off and control equipment; they will probably be forced to install a CO sensor and a gas shut-off machine. The fourth part usually describes the details of installation work. Schemes and drawings of gasification are submitted in addition to the project.

Conducting gas

With the project ready, we set off to look for a contractor. This could be a team of UGH welders or a private enterprise. In theory, you can pipe gas from the house to the extension of the bathhouse with your own hands, but no one will allow you to connect it to gas equipment, unless you do it illegally. But in this case, any fire or force majeure situation with gas can result in severe financial consequences.

Installation of equipment

The only thing you can do yourself is to install a gas boiler, boiler or heater. True, this must be done in good faith, following all the requirements of the gasification project, maintaining distances from the walls, ensuring the walls are covered with non-flammable material, laying electrical wiring and grounding.

Pipe laying

Specialists must directly pull the pipe from the point of insertion into the gas main to the connection point in the bathhouse. If we are talking about welding work, then it must be performed by a certified welder. Pipes for gas supply must be special, exactly the diameter specified in the project for gasification of the bathhouse extension.

Important! The cross-section of the pipe determines the maximum gas consumption of the bathhouse equipment. A situation is possible when the gas supply from the street main to the house is made through a pipe of smaller diameter. It should be at least an inch and a quarter, in practice it could be an inch.

As a result, the gas throughput into the house is no longer enough to simultaneously operate home heating simultaneously with heating the steam room. In this case, you have to change the input; no one will allow making a separate connection for an extension within the same household.

If the capacity of the pipe from the main to the house, taking into account the bathhouse, is not enough, then the gas injection design will have to be redone, and this will almost double the work estimate.

It’s easier with plastic, but it must be placed in the ground in a protective casing; in addition, pipes must be soldered by a specialist with permission to do this kind of work and always with his own equipment. The trench is not backfilled until the integrity of the main has been checked.

Laying a metal pipe, even within several adjacent rooms, is always associated with a lot of inconvenience, so welders and mechanics always strive to “cheat” and simplify the work, reduce the radius somewhere, in general, do it their own way. You need to monitor this and demand that the work be completed exactly according to the project. For example, attempts to weld a pipe string from several sections instead of a whole length should be immediately stopped and installation should be required with a minimum number of seams.

Starting the bath heating

Upon completion of the installation work, the pipe is equipped with a shut-off valve and connected to the previously installed equipment. The central valve at the exit to the house and on the equipment in the steam room is sealed.

Next, you will need to bring a gas inspector from the UGC Operations and Supervision Department. He draws up an inspection report and gives permission to start gas supply for the new project.

The last step is to conclude a service agreement and start up the heating equipment in the bathhouse. Usually an engineer or representative of a company that sells boilers or furnaces is invited to check and start up the boiler unit. Every year you will need to carry out the warranty service procedure, otherwise the warranty will become invalid.
