The problem associated with the lack of central heating and hot water supply, as well as the poor quality of these services, can be solved today by installing a gas boiler.
Boiler selection
To do this, you can choose single-circuit or double-circuit equipment. The first option is able to provide only one process, which can 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 follow all the 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 follow fire safety rules.
Basic rules for installing gas equipment
If you decide to install a gas boiler in a privatehouse, then you will need to prepare documents and carry out certain actions. A contract for the supply of gas to an individual consumer will be needed. The installation project, as well as all technical conditions, must be agreed with the city representative of the gas service. The heating system must be pressurized to 1.8 atm.
It will be important to de-air the heating system. The master will have to analyze the connections for leaks. A voltage stabilizer is mounted for the boiler, it is important to take care of the availability of an uninterruptible power supply. It is unacceptable to supplement the heating water with antifreeze. Doing so may damage the seals, resulting in leaks in the heating system.
Requirements for the premises
If you decide to install a gas boiler in a private house, it is important to check how the room complies with the standards. We are talking about the room in which the boiler is supposed to be placed. Installation of a boiler in a single-family house may involve the arrangement of a furnace or boiler room at any level, it can be a roof, attic, basement or basement. Living quarters, as well as a bathroom and a bathroom, act as a restriction. To determine the volume of the room, which will play the role of a boiler room, it is necessary to take into account the total thermal power of the equipment, storage or instantaneous water heaters. When installing a gas boiler in a private house, it is recommended to take into account that there are some exceptions. Thus, if the boiler has a closed-type combustion chamber, then the volumethe boiler room is not standardized, a window with access to the outside may also not be installed.
Air supply
For the removal and supply of air, it is important to organize the inflow of the required volume. In order to provide equipment power of 23.3 kW, about 2.5 meters of cubic gas must be burned per hour. In order for this volume to completely burn out, it will take 30 cubic meters of air for an hour. If an insufficient amount of oxygen is supplied, the gas will not burn completely, eventually a harmful substance will begin to accumulate, while its inhalation will adversely affect human he alth.
If you are installing a gas boiler in a private house with your own hands, then it is especially important to ensure that air flow is ensured not only from the outside, but also from other rooms of the house. This can be achieved by creating a gap between the floor and the door. It is necessary to 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 work on the installation of gas equipment
Installation of a gas boiler in a private house, the price of which should interest you at the first stage, involves compliance with the rules and regulations. When planning the room in which you intend to place the boiler, you need to make it such that the area is equal to 4 square meters or more. Ceilings must be 2.5 meters high or more. Importantpay attention to the width of the door that goes into the room, it should be equal to 80 cm. Installation of a wall-mounted gas boiler in a private house is done in such a way that the equipment is lit naturally through the window opening.
It is important to consider that for every 10 square meters there should be 0.3 square meters of window. Be sure to provide intensive ventilation, since the combustion of gas is carried out due to the flow of air. The area of the opening for the intake of outside air should be 8 centimeters square per 1 kW of equipment power.
When installing a floor-standing gas boiler in a private house, it is important to take into account the fact that gas pipes must be made exclusively of metal. It is important to remember that flexible hoses can only be used to connect consumers.
What you need to know about the section of the chimney
Do not neglect the cross-section of the chimney, which must correspond to the available power of the boiler. In the event that the power of the equipment is 30 kW, then the diameter of the chimney should be equivalent to 130 millimeters. When installing gas boilers, the rules and installation features require the use of a chimney with a diameter of 170 millimeters with an equipment power of 40 kW. It is unacceptable that the cross-sectional area of the chimney is smaller than the cross-sectional area of the opening for connecting the chimney. The upper end of the chimney should be 0 above the roof ridge,5 meters or more. In the electrical power supply system of the equipment, there must be an automatic machine that 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 must work in conjunction with a gas analyzer that 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 that shuts off the fuel supply. If you have to work in an apartment building, it is unacceptable to install gas equipment in the basement. Each device must be supplemented with gas meters. As for ventilation, it should also be in the upper part of the room.
Features of installation of wall-mounted equipment
When gas boilers are installed in a private house, the workflow allows you to eliminate errors. Wall-mounted equipment is mounted in cases where the power requirements are not too strict. Among other things, such an arrangement of equipment can be chosen when there is not too much free space. Most often, such boilers are used in multi-storey buildings. Installation of wall-mounted equipment makes it possible to provide an independent additional heating system, which can be installed even in houses with central heating. Do-it-yourself installation of a gas boiler in a private house can be carried out above other appliances that are installed on the floor, this is due to the fact that the boilers are not toodemanding on free space. It is permissible to mount wall-mounted equipment in a cascade. This is useful if there is a need for significant power.
Recommendations from 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 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 walls. The power supply should be located as close as possible. Before the boiler is installed in its place, all pipes of equipment and systems must be flushed with water. This will get rid of foreign particles that may have been in the system during the assembly process.
Nuances of the work
The bars that are used to fix the boiler must be installed in 0.8 meter increments, as for 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 and related appliances. When a wall-mounted gas boiler is installed in a private house, the wall is supplied with a gasket made of non-combustible material, the thickness of which should be equal to 3 millimeters. The boiler in this case is fixed at a distance that is equal to 4.5 cm from the wall surface.
Before the equipment is connected to the pipes, it is necessaryget rid of the plug that is installed on the nozzles. In order to prevent clogging of the heat exchanger, it is recommended to install an angle strainer at the water inlet. It is important to install ball valves on both sides of it, this should greatly simplify further maintenance and repair. After that, it is important to check how evenly the equipment is installed. Skewed to one side can lead to negative consequences. Connection of gas pipes to the equipment should be carried out using a steel pipe through special bends, it is important to ensure a rigid connection. It is important to use a paronite gasket. On this we can assume that the installation of a gas boiler in a private house, the price of which starts at 5,000 rubles, is completed.
Requirements for the device of the chimney
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, it is preferable to use stainless steel. Such products will be the safest, most reliable and durable. It is important to install a hatch to clean the chimney. In order to make it convenient to collect soot during the cleaning process, it is necessary to leave an empty space under the chimney inlet. When installing this part of the boiler equipment, you should not make turns and knees in the amount of more than three pieces.
The pipe that connects the chimney to the boiler should be as short as possible, its length should not exceed 25 cm. The vertical section at the outlet of the equipment shouldbe equal to 2 diameters or more. Behind this section, the pipe must be led to the connecting section, and after it it must be turned upwards with a slight slope towards the equipment. Smoke removal in this case will be carried out due to natural draft.
Conclusion
The cost of installing a gas boiler in a private house will be less if you install all the equipment yourself. However, it is necessary to take into account the fact that the connection of the system is still carried out by a professional team of craftsmen. This is necessary in order to strictly comply with all fire safety rules and regulations. After all, this is the only way to protect yourself and your home from a fire that can occur due to improperly installed heating equipment.
