Where to install a gas boiler - installation of a gas boiler

Currently, in many houses and apartments geysers and boilers are often installed. Thanks to them, both the heating of cold water and the heating of dwellings takes place. Advantageously, separate devices with a single circuit are used to heat the carrier with hot water and heating systems. There are options with a combination of single-circuit heater and an additional boiler - this is inconvenient, since a relatively large area is required for the installation of units.

In this regard, in different types of dwellings in which does not exist the need to use large amounts of hot water, dual-circuit devices are becoming more and more popular. They heat the water and supply it to both systems at once - both for heating and for household needs. As a rule, more questions arise when choosing where to install a gas boiler than with its installation.

Device and principle of operation

Dual-circuit and single-circuit gas boilers do not differ much in design, since in both cases the burner heats the tubes with water flowing through them. The main difference is manifested in the ability of the units for two circuits to heat water simultaneously for supply in different directions. This is due to a specific design consisting of divided pipes, from which water is separately supplied to the heating and hot water network.

At a superficial examination of a double-circuit boiler, you can see a pipe bent many times with an integrated grille. But, in essence, the design of the unit is a bit more complicated. Inside the coil, through which water enters the heating system, another tube is arranged, designed to supply coolant to the hot water network. In this case, it is necessary to emphasize one important nuance.

Water in the external and internal pipes flows in opposite directions - this improves heat transfer. Even at the design stage, and especially when working on the connection of a gas boiler, this feature must be taken into account.

The presence of two heating circuits in the unit at once determined the number of pipes, who need to connect during installation. If there are 3 exits in a single-circuit boiler for connecting pipes, in a double-circuit one there are 5.

Installation regulation

The owner, who has decided to install a gas boiler, for example, of a double-circuit type, in his apartment or house should know that only organizations and structures specializing in this equipment are involved in installing and connecting such equipment type of work. They must have a license for this type of activity. Unauthorized connection of such devices "shines" to the owner of the dwelling with a very considerable fine. However, the limited work involved in preparing the installation of the unit and collecting the necessary certificates and permits should be done by the owner of the apartment or house.

The installation of gas equipment is regulated by the relevant regulatory documents. The following building codes and norms can be counted among them: SNiP 42-01-2002, SNiP II-35-76, and also the set of rules SP 41-104-2000.

Boiler installation norms

  • Requirement for the installation room - an area of ​​at least 4 m², the height of the ceilings cannot be less than 2.5 m.
  • Door opening leading to the installed boiler should not already be 0.8 m.
  • A window must be provided, the size of which is calculated for certain reasons. With a room square of 10 m², the window opening area must be at least 0.3 m².
  • Where to install a gas boiler - installation of a gas boiler Ventilation Availability of high-quality ventilation, as gas requires a constant flow of air for good combustion. The power of the device in 1 kW corresponds to a hole of 8 cm². These conditions are observed for boilers whose combustion chamber is closed. For their proper functioning, coaxial chimneys are used, supplying air and exhaust products arising in the combustion process.
  • The size of the chimney depends on the performance of power, while there is a specially developed formula for the calculation. If we take into account the fact that devices with a capacity in the range of 30-40 kW are most demanded, then chimneys with a diameter in the corridor of 130-170 mm are most suitable for them.
  • The chimney at its upper end should be removed above the roof surface by 0.5 m. If a coaxial chimney is used, its upper end should rise above the air intake pipe by 0.2 m or more.
  • Metal pipes are used for wiring in the main gas pipeline house. At the transitional section connecting the pipeline with the boiler, it is allowed to use corrugated pipes characterized by their flexibility.
  • Where to install a gas boiler - installation of a gas boiler Gas analyzer A gas analyzer must be installed in a room with this type of heater.
  • Private houses have an advantage over apartments because the installation of boilers is allowed in their basements. If the question arises, where it is possible to install gas appliances in high-rise buildings, then a kitchen or rooms that meet certain standards are suitable for this.
  • Where to install a gas boiler - installation of a gas boiler Gas meter A connected gas meter is required.
  • A cold water supply pipe is required in a room with a mounted boiler.
  • The walls of the room, planned for the installation of the gas boiler, must be in proper condition - be flat and trimmed.
  • Forbidden for the installation of such equipment, it is possible to classify bathrooms, corridors, balconies, basements of "high-rise buildings" and rooms without windows. Also, hostels are not intended for installation.
  • The minimum distance between the appliance and the near wall is 0.15 m. From the ceiling of the room to the upper end of the chimney should be 0.2 m or more. The distance from the part of the chimney that goes outside to the wall is at least 0.3 m. The hinged heater should rise above the floor surface by 1.0 m - 0.8 m is allowed. The wall at the installation site is carefully insulated.

If the combustion chamber is closed in a dual-circuit boiler, the accommodation room may be windowless.

If all of these conditions and rules are met in the relevant authorities, you can easily obtain documents authorizing the installation of gas equipment in a private house or apartment.
