Installation of a gas boiler in a private house: technology

The problem, which is related to the lack of central heating and hot water supply, as well as poor quality of these services, can now be solved by installing a gas boiler.

Boiler selection

For this, you can choose single-circuit or dual-circuit equipment. The first option is able to provide only one process, which may be, for example, heating. Whereas dual-circuit equipment guarantees two processes, namely heating and water heating. Installation of a gas boiler in a private house is quite troublesome and time consuming, this is largely due to the fact that the master will have to monitor compliance with all rules and regulations. It is also worth remembering that the operation of such equipment is always associated with some risks, which is why it is necessary to comply with fire safety rules.

Basic rules for the installation of gas equipment

If you decide to install a gas boiler in a private house, you will need to prepare documents and carry out certain actions. You will need a contract for the supply of gas to an individual customer. The installation project, as well as all technical conditions, must be coordinated with the city representative of the gas service. The heating system must be pressurized to 1.8 atm.

It will be important to deaerate the heating system. The master will have to analyze the connections for leaks. For the boiler mounted voltage regulator, it is important to take care of the presence of an uninterruptible power supply. It is inadmissible to supplement the water with antifreeze. This can cause damage to the gasket, which will lead to leaks in the heating system.

Requirements for premises

If you decide to install a gas boiler in a private house, it is important to check how much the premises meet the standards. This is the room in which the boiler is supposed to be placed. Installation of a boiler in a single-family home may involve the arrangement of a furnace or boiler house at any level, such as a roof, an attic, a basement or a basement. As a limitation, there are residential premises, as well as a bathroom and a bathroom. To determine the volume of the room, which will play the role of a boiler house, it is necessary to take into account the total thermal capacity of the equipment, capacitive or instantaneous water heaters. When installing a gas boiler in a private house, it is advisable to take into account that there are some exceptions. Thus, if the boiler has a closed type combustion chamber, then the boiler room volume is not normalized, a window with an outlet outside may also not be installed.

Inflow of air

For the removal and supply of air it is important to organize the inflow of the required volume. In order to ensure the capacity of the equipment at 23.3 kW, about 2.5 meters of cubic gas per hour should burn. In order for this volume to completely burn, it will take 30 meters of cubic air for an hour. If there is insufficient oxygen, then the gas will not burn completely, eventually the harmful substance will start to accumulate, whereas its inhalation will negatively affect human health.

If you install a gas boiler in a private house with your own hands, it is especially important to ensure that there is an air supply not only from the outside, but also from other premises of the house. This can be provided by the method of creating a gap between the floor and the door. Mount the boiler on the floor with a step of 10 cm from the wall, which is important to cover with non-combustible material.

Features of the installation of gas equipment

Installation of a gas boiler in a private house, the price of which you should be interested in at the first stage, implies compliance with rules and regulations. When planning a room in which you intend to locate the boiler, it is necessary to make it so that the area is 4 meters square or larger. Ceilings should be a height of 2.5 meters or more. It is important to pay attention and width of the door that goes into the room, it should be equal to 80 cm. Installation of a wall gas boiler in a private house is done in such a way that the equipment is illuminated naturally through the window opening.

It is important to take into account that for every 10 square meters there should be 0.3 square meters of window. It is imperative to provide intensive ventilation, since the combustion of the gas is due to the influx of air. The area of the opening for external air intake should be 8 centimeters square per 1 kW of equipment capacity.

When installing a floor gas boiler in a private house, it is important to take into account the fact that the pipes of the gas pipeline must be made entirely of metal. It is important to remember that flexible sleeves can only be used to connect consumers.

What you need to know about the chimney section

Do not neglect the chimney cross-section, which should correspond to the existing boiler output. In the event that the capacity of the equipment is 30 kW, the diameter of the chimney should be equivalent to 130 millimeters. When the installation of gas boilers is made, the rules and installation features suggest the use of a chimney diameter of 170 millimeters at a power of 40 kW. It is inadmissible that the area of the chimney section is smaller than the sectional area of the chimney connection. The upper end of the chimney must be above the roof ridge by 0.5 meters or more. In the electrical power supply system of the equipment there must be an automatic device, which is equipped with thermal and current protection.

Features of installation of boiler equipment

If you are installing, a gas boiler for heating a private house should work together with a gas analyzer, which will be able to warn of a possible gas leak. Among other things, it is necessary to take care of the presence of an electric valve, which blocks the supply of fuel. If you are going to work in a multi - apartment apartment building, it is not permissible to mount gas equipment in the basement. Each device must be supplemented with gas meters. As for ventilation, it should be at the top of the room.

Features of the installation of wall-mounted equipment

When the installation of gas boilers in a private house is made, the scheme of work permits the elimination of errors. Wall-mounted equipment is installed in cases where the power requirements are not too strict. Among other things, this arrangement of equipment can be selected when there is not too much free space. Most often such boilers are used in multi-storey houses. Installation of wall-mounted equipment allows to provide an autonomous additional heating system, which can be installed even in houses with central heating. Installation of a gas boiler in a private house with your own hands can be carried out over other appliances that are installed on the floor, this is because the boilers are not too demanding for free space. It is permissible to mount the wall equipment in a cascade. It is advisable in the event that there is a need for considerable power.

Recommendations of a professional master

Installation of a gas boiler with an indirect heating boiler can be carried out at a distance of 20 centimeters from other gas appliances, as well as materials that are highly flammable. Depending on the model of equipment and power, the distance between the boiler and the wall can vary from 30 to 50 centimeters. It is not recommended to place the boiler near a window or in an opening between the walls. The power supply must be as close as possible. Before the boiler is installed in its place, all pipes and equipment must be washed with water. This will get rid of foreign particles that could be in the system during the assembly process.

Nuances of works

The slats that are used to fix the boiler must be set in steps of 0.8 meters, as far as the maximum distance, it is 1.6 meters from the floor surface. It is necessary to analyze the wall for evenness and strength, it must withstand the weight of the boiler itself of the associated devices. When installing a wall gas boiler in a private house, the wall is supplied with a gasket of non-combustible material, the thickness of which should be 3 millimeters. The boiler in this case is fixed at a distance that is 4.5 cm from the wall surface.

Before the equipment is connected to the pipes, it is necessary to get rid of the plug, which is installed on the nozzles. In order to prevent clogging of the heat exchanger, it is recommended to mount a corner mesh filter at the water inlet. On both sides it is important to install ball valves, this should greatly simplify further maintenance and repairs. After that, it is important to check how exactly the equipment is installed. Skewing to one of the parties can lead to negative consequences. The connection of gas pipes to the equipment should be carried out using a steel pipe through a special drill, it is important to ensure a rigid connection. It is important to use a paronite gasket. This may be considered that the installation of a gas boiler in a private house, the price of which starts from 5000 rubles, is completed.

Requirements for the chimney device

It is important to choose the right material for the chimney, which will depend on the type of equipment and the fuel used. For a gas boiler it is necessary to use pipes that have a cylindrical shape and are made of metal, preferably stainless steel. Such products will be the most safe, reliable and durable. It is important to install a hatch for cleaning the chimney. In order to be convenient to collect soot during the cleaning process, it is necessary to leave an empty space under the entrance of the chimney. When installing this part of the boiler equipment it is not necessary to make turns and knees in an amount of more than three pieces.

The pipe that connects the chimney to the boiler should be as short as possible, its length is not more than 25 cm. The vertical section at the outlet of the equipment should be equal to 2 diameters or more. For this segment, the pipe must be moved to the connecting section, and after it must be turned up with a slight bias towards the equipment. Smoke removal in this case will be carried out at the expense of natural draft.

Conclusion

The cost of installing a gas boiler in a private home will be less if you install all the equipment yourself. However, it is necessary to take into account that the system is still connected by a professional team of masters. This is necessary to ensure that all the rules and regulations for fire safety have been strictly observed. It's the only way to protect yourself and your home from fire, which can occur due to improperly installed heating equipment.
