Currently, many homes and apartments are often installed gas water heaters and boilers.Thanks to them, going as heating cold water and heating homes.Mostly for heating support with hot water and heating use different boilers with one loop.There are embodiments with a combination of single-loop boiler and an additional boiler - is inconvenient, since it takes a relatively large area for installation of units.
Single-circuit boiler and boiler
In this regard, the different types of dwellings, in which there is no need to use large amounts of hot water are becoming increasingly popular combi boilers.They heat the water and serve it immediately to both systems - both for heating and for domestic use.Installation of gas boiler is connected with a number of difficulties.First and foremost, they arise when choosing a place where to install a gas boiler, rather than with its installation.
Design and Function
Double-circuit and single-circuit gas-fired boilers structurally little different, since in both cases the gas burner heats the tubes with water flowing over them.However, the main difference is manifested in the possibility of units on two circuits simultaneously on heating water supply in different directions.This is due to a specific structure consisting of separated tubes, from which water is separately supplied to the heating and hot water supply network.
Driving gas boiler
A superficial examination of a bypass of the boiler can be seen many times curved pipe with integrated grille.But, in fact, the design of the machine a little more complicated.Inside the coils, through which water flows into the heating system is arranged another tube for supplying coolant in the hot water supply network.It is necessary to emphasize one important caveat.
Wiring the Single-boiler
water in the outer and inner tubes flowing in opposite directions - this improves heat boiler.Even at the design stage, and especially when dealing with the connection of the gas boiler, this feature must be considered.
gas boiler in the kitchen
owner, who decided in his apartment or house to install a gas boilerFor example, a bypass type, should be aware that the connection of the equipment should be engaged only organizations and structures that specialize in this type of work.They must have a license for this type of activity.Unauthorised installation of a gas boiler and its connection "light" owner home very considerable fine.However, the limited job is to prepare for the installation of the unit and collect the necessary certificates and permits necessary to do to the owner of the apartment or house.
Installation of gas boiler is regulated by normative documents, which relate to this type of activity.These could be considered the following building regulations: SNIP 42-01-2002, SNiP II-35-76, as well as a set of rules SP 41-104-2000.
Standards boiler installation
- room allotted for the gas boiler should not have an area of less than 4 m², with the ceiling height must be equal to or greater than 2.5 m.
- openings for doors leading into the room with the mounted boiler withoutIt should already be 0.8 m.
- The room should be present window size is calculated from the specific considerations.When squaring the premises of 10 m² area of the window opening should be at least 0.3 meters.
- Ventilation As for good combustion gas requires a constant flow of air, the room should be equipped with high-quality ventilation.Boiler capacity of 1 kW corresponds to the opening area of 8 cm².This condition is met for boilers, combustion chamber that is closed.For their proper functioning used coaxial chimneys, through which air is supplied to the boiler and flue occurring in the combustion process.
- size of the chimney depends on the performance capacity of the boiler, with calculation exists specially developed formula.If we take into account the fact that most in demand within the capacity of the boilers 30-40 kW, for them the most suitable chimneys diameter 130-170 mm in the hallway.
- chimney in an upper end thereof to be output over the roof surface to be 0.5 m. If the applicable coaxial chimney, it must extend the upper end of the intake pipe 0.2 m or more.
- for wiring in the building of gas pipeline used metal pipes.In the transition region connecting the pipe to the boiler allowed to use corrugated pipe, characterized by their flexibility.
- analyzer in the room with the boiler must be installed analyzer.
- Homes have advantages over apartments, because in their cellars allowed the installation of gas boilers.If the question is where to set the gas units in high-rise buildings, then this fits the kitchen or room, meeting certain standards.
- Gas meter The boiler must always be connected gas meter.
- in the room with the installation of the unit must be present cold water supply pipe.
- walls of the room, planned for the installation of a gas boiler, must be in good condition.They must be smooth and finished.
- to the room in which it is impossible to install a gas boiler, it is possible to classify bathrooms, hallways, balconies, basements, "high-rise" and a room with no windows.To install the boilers are not designed hostel.
- between the gas plant and the near-wall should be free space, which is defined by a minimum distance of 0.15 m. From the ceiling of the room to the upper end of the chimney must be 0.2m or more.Part of the chimney, facing the outside shall be at a distance from the building wall 0.3 m. Hanging the boiler must rise above the floor surface of 1.0 m - 0.8 m is allowed. The boiler must be separated from the wall insulation boards.
if all of these conditions and the rules of the relevant authorities can easily obtain documents allowing the installation of the gas unit in a private house or apartment.
