The advantage of the devices is the cost of generating heat compared to all other types of boilers. The disadvantage is the need for a central gas supply system and the constant availability of power.

Gas boilers are suitable for heating and hot water supply of residential apartments and country houses, being a cheaper alternative to central heating.

General characteristics of boilers

Familiarity with the characteristics is necessary for right choice device models:

  • Execution - floor or hinged. The hinged version has more compact dimensions, but also a smaller generated thermal power. Differences in functionality in modern models no.
  • type of combustion chamber. An open chamber draws air from the room, and emits flue gases through the chimney. The closed chamber can take in air and exhaust exhaust gases one at a time. coaxial pipe. For installation in an apartment, it is preferable closed chamber combustion.
  • Thermal power of each circuit in kW. The area of ​​the heated room depends on the parameter. Estimated calculation of 1 kW per 10 m 2 of the room.
  • Efficiency factor (COP). Characterizes the efficiency of the device for the transfer of energy obtained by burning gas. The higher the efficiency, the less fuel is required to heat the water.
  • The temperature of the heat carrier in °C and the range of its regulation. It is necessary to select a device that provides the desired temperature.
  • Circuit capacity in liters per hour. When evaluating this parameter, it is necessary to take into account the average water consumption for hot water supply, it may be advisable to use a storage structure with an installed one.
  • Availability of protection and comfort control functions, a wide range of operating modes.

Instrument selection

When choosing a device, you must be guided by the following criteria:

  • The area of ​​the heated room in m 2. It is necessary to choose a boiler based on 1 kW of heat output per 10 m 2 of the room. At the same time, it must be understood that this perfect option and taking into account the heat loss of the dwelling, the average annual air temperatures at the installation site and the radiators used, it is required to introduce a correction factor. For a preliminary assessment, we advise you to use any online calculator that takes into account the above factors, and also introduces corrections for the location of the walls (windward or not), ceiling height, type of windows.
  • Need for hot water. For large consumption, it is reasonable to choose the CLAS B model with an integrated boiler, which is more economical.
  • Location of the boiler. For water heaters with an open combustion chamber, room equipment is required supply ventilation because the combustion air comes directly from the room. Since devices with an open combustion chamber are designed to remove combustion products through a natural draft chimney, it is necessary to provide for the installation location of the chimney and chimneys.

    IMPORTANT! It is not allowed to pass chimneys through structures made of combustible material.


 Gas boiler device

Boiler malfunctions

Most of the malfunctions that occur can be prevented at the boiler installation stage. Here is a list of the main malfunctions, their causes and measures to prevent the failure of the device:

  • Failure of the control board. It occurs, as a rule, due to poor quality of electricity - power surges, frequent power outages. To prevent breakdowns for this reason, it is necessary to provide. For a private house, a good solution would be to install a backup diesel generator and an automatic transfer system. Need to protect your device circuit breaker, power it through a separate cable line and securely ground it.
  • Deterioration of the passport characteristics of the device, expressed in undercooling of water or reduced performance during heating. It is associated with the presence of contaminants in the water, excessive water hardness. In both cases, deposits appear on the heat exchanger tubes, which impede the heating and passage of water in the system. To solve the problem with contamination, it is necessary to install a filter, and when using water with a high calcium content, it is recommended to heat the water to 45-50 ° C.
  • Frequent stops due to insufficient water pressure. The fault is detected by the instrument and triggers a protective stop. BEFORE purchasing the unit, find out the parameters of the water supply network and make changes to it if the pressure is below 1.5 bar. If the pressure is higher than 6 bar, consider installing a pressure reducing valve. If the parameters of the main network are normal, then turn off the boiler and check the system for leaks.
  • Frequent stops on the smoke exhaust system. BEFORE installing the unit, calculate and install the gas ducts and chimney providing the required traction.
  • Frequent stops due to lack of air. Before installing the appliance, equip the room with a supply ventilation system.
  • Non-compliance of the operating modes with the declared ones, non-compliance of the coolant with the specified parameters. The main reason is incorrect commissioning and incorrect device settings. Careful reading of the instructions often solves the problem. If necessary, a qualified person should be called in to commission and instruct the device.
  • When choosing a model, please contact the company which will pick necessary equipment based on your requirements;
  • Trust the installation and commissioning of the device qualified specialist;
  • Read the instructions carefully for operation;
  • Do not neglect periodic preventive examinations and maintenance of equipment;
  • In case of any frequent malfunction, turn off the boiler and call a qualified specialist;
  • Trust repair and supply of spare parts only certified organization.

Installation of a gas boiler and its connection to the system is the most effective method organization of heat supply in a house or apartment. Control services have special requirements for the premises. To install a gas boiler, it is necessary to carry out a number of preparatory work.

The installation of equipment is preceded by measures to adapt the premises in accordance with applicable requirements. They are detailed in the Technical Specifications issued by Oblgaz or Gorgaz. This is true for the organization of heating on liquefied or natural gas. But usually, in the latter case, the issuance of an official permit is neglected, which can lead to a serious fine and a ban on the use of the existing heat supply system.

The document regulating the requirements for the premises for the installation of gas heating boilers is developed on the basis of the following regulations:

  • SNiP 31-02-2001. Designed for control construction works and building design.
  • SNiP 42-01-2002. Describes the rules for organizing gas distribution systems.
  • SNiP II-35-76 in the latest edition of 2012. They are guided by the choice of boilers and similar gas equipment.
  • SNiP 42-01-2002 and SP 41-104-2000. Needed to comply with standards when designing autonomous sources of heat supply.

It can take a long time to study these documents. In fact, about 20% of their content is devoted to the organization of domestic heat supply using gas boilers. To avoid wasting time, we recommend that you familiarize yourself with useful excerpts from regulations.

Requirements for the organization of the boiler room

If the boiler power does not exceed 200 kW, any built-in rooms of the house can be used as a boiler room. These include basement and basement rooms. For boilers up to 30 kW, the minimum room volume must be at least 7.5 m³. Accordingly, for equipment from 30 to 60 kW - 13.5 m³, more than 60 kW - from 15 m³. You also need to take into account other characteristics of the boiler room.

These include the following requirements:

  • square air vent for gas boilers up to 30 kW - 0.02 m², from 30 to 200 kW - 0.025 m² ();
  • the distance from the protruding parts of the equipment to the walls is regulated by the manufacturer;
  • the presence of a transom or window to reduce the concentration of gas in case of leakage, providing a three-fold replacement of air in 1 hour;
  • natural and artificial lighting of the room, the ratio of window area to volume - 0.03 m² per 1 m³;
  • if the boiler room is located on the first or basement floor, they must equip a separate passage, the door must open outward;
  • ceiling height - not less than 2.5 m;
  • a refractory material is installed on the walls in the boiler installation area, the fire resistance limit of which is at least 0.75 hours.

Placement of heat supply components is free. The main requirement is that nearby objects should not interfere with repair or maintenance work.

Characteristics of the kitchen for the installation of a gas boiler

The power of most gas boilers rarely exceeds 30 kW. This makes it possible to install them in the kitchen of a house or apartment. This is also done by agreement of the controlling organizations. Many of the above rules apply for this case, but given the specifics of the premises, there are additional ones. for a boiler with an open combustion chamber, three air exchanges are provided within one hour;

  • the wall at the installation site must be made of non-combustible materials, the minimum distance from it to the boiler is 10 cm;
  • for wall models, the distance to the ceiling is from 15 cm, to the side wall - from 10 cm;
  • when installing boilers with an open combustion chamber, it is forbidden to install an exhaust hood.

    • In practice, preparing the kitchen will require much less effort. Thus, ventilation can be provided by installing a lattice or a gap of 0.02 m² in the lower part of the door.

    These rules are not "ultimate truth". The main document for preparing the boiler room for the installation of gas equipment will be the Technical Conditions.
