In an effort to provide our home with heat during the cold period, we often face the choice of a suitable unit for the heating system. Among the variety of gas heating equipment I want to choose an efficient, cost-effective and affordable installation. Gas wall-mounted double-boiler with a closed combustion chamber may well become a priority option in your case.
Gas wall double-boiler with a closed combustion chamber: the benefits
Gas boilers of a closed type are used for autonomous heating of small industrial premises, offices and private houses. Wall-mounted gas boilers for heating with a closed combustion chamber have several advantages, relative to other similar equipment:
- in the process of work, oxygen is not consumed from the room where the wall-mounted gas boiler is installed;
- the flow of combustion air is provided without the involvement of additional devices;
- for heating all rooms of the room, the boiler consumes the optimal amount of gas;
- to use the boiler in private homes there is no need to equip the chimney;
- individual selection of a suitable mode of operation;
- compact dimensions;
- affordable automatic control;
- a wide range of models presented (user reviews of popular boilers can be found on the manufacturers’ websites).
Gas boilers, which are based on a closed combustion chamber, are safe and can be installed directly in a heated room without the risk of lack of oxygen in it. This is ensured by a special pipe layout (one inside the other). Air is supplied through one pipe to ensure the combustion process, and carbon monoxide is discharged through the other. Thus, the exhaust gas is completely prevented from entering the room.
Wall-mounted gas boilers for heating in a modern design are quite compact equipment consisting of the following structural elements:
- functional housing;
- heat exchanger block;
- circulation pump;
- temperature controllers and sensors;
- expansion tank;
- complete security system;
- removal of combustion products into the chimney (forced);
- Control Panel.
The model with which control (electronic or mechanical) to choose for you – find out, reading the consumer reviews.
Given the number of circuits and the wiring diagram, the wall-mounted gas boiler can be equipped with an additional heat exchanger, fan, and shut-off valves.
Coppers of the closed type can be convection and condensation. In convection models, the evolved vapor is removed to the outside, and in the condensation model, this vapor is used to heat an additional heat exchanger. Models have their pros and cons. Convection boilers are simple, cheap and easy to manage. Condensation are high performance, but they are much more expensive.
An open-type combustion chamber boiler uses room air for combustion, which can lead to a lack of oxygen. Such a boiler can be installed only in a separate room (boiler room), its chimney must be vertical. From the reviews you can find out that the price of such a boiler is relatively moderate.

Unlike heating appliances with an open-type combustion chamber, a turbocharged wall-mounted boiler provides air supply and removal of combustion products through a coaxial chimney, the principle of which is the simultaneous discharge of exhaust gas and external air intake. Important advantages of the boilers with a closed combustion chamber are the safety of the installation in a residential area, high performance (heat exchange between the supply and exhaust) and the level of increased comfort in the house.
Helpful advice! For efficient operation of the gas wall boiler, it is necessary to choose a place for installation near the external wall or the ventilation shaft of the room.
The boiler with a closed chamber does not require a specially equipped separate room with the provision of all fire regulations. The flue may be horizontal and small in length. A device with such a combustion chamber has a high level of safety:
- gas leakage protection;
- protection against pops during ignition;
- protection against excessive water heating;
- control of the fan.
This boiler is suitable for installation both in a private house and in apartments (mainly in kitchens) of multi-storey buildings. Taking into account the likely absence of high-rise hot water in high-rise buildings, the use of gas wall-mounted double-circuit boilers with a closed combustion chamber in them will be quite reasonable. Reviews indicate the frequent use of such boilers in residential apartments.
Wall-mounted boilers with a closed-type combustion chamber are divided into single-circuit and double-circuit. Models of gas wall-mounted single-circuit boilers for home heating work only for heating radiators. If there is a need for hot water, then you should choose a single-boiler with the ability to connect to it a water heater (boiler) side heating. Such a single-circuit boiler can satisfy the needs of hot water for a large family living in one private house. Another option for single-circuit design is a single-circuit boiler with a built-in boiler. It has large dimensions. The price of such boilers is noticeably higher, however, it pays for itself with an uninterrupted supply of hot water, even in flowing mode. On which model of single-wall wall boiler is better to choose, learn from user reviews.
The device of gas wall-mounted boilers for heating a house allows you to function both for heating and for preparing hot water. Such boilers are equipped with two circuits. When using hot water, the flow of coolant to the heating system is stopped. The double-circuit boiler is equipped with a valve that automatically stops heating the heating circuit during the use of hot water. This gives many a reason to think that at this time the radiators are cooling down. As a rule, the percentage of temperature reduction in radiators is negligible (consumer reviews confirm this).
There are models of double-wall boilers in which heating of the heating circuit is provided by an additional heat exchange unit. In such installations, hot water transfers part of the heat to the heating circuit (heat recovery principle). Reviews of such equipment indicate high performance boilers.
Helpful advice! The gas wall double-circuit boiler equipped with a boiler ensures independence from the water pressure supplied by the water supply system.
What criteria need to be considered when choosing a gas wall bypass boiler? How to choose a model that fits your room? First of all, you should pay attention to the following indicators:
- equipment power;
- economical installation;
- conditions and complexity of installation;
- price of the heater.
How to choose power. The power figure is usually calculated by a specialist. If this is not possible, you can resort with the generalized method of the so-called integrated calculation. Its essence is that for heating one square of the floor space, it will take 0.1 kW of heat energy. So, you can find out the required power (kW) by multiplying the entire area of the heated room by the number 0.1.
As for the indicator of efficiency, the wall-mounted boiler of the closed type due to the efficient combustion of gas is a device with high efficiency (up to 98%) at rated power.
Helpful advice! The wall gas boiler of the closed type is a volatile device. If electricity is frequently cut off in your area, this should be considered when choosing a boiler.
The complexity and cost of installation depends on where it is supposed to place the installation of a gas double-circuit wall boiler. How to choose a place in the kitchen or bathroom? This will help specialists-installers of gas equipment. If exact placement in the constrained conditions is required, installation will cost a little more expensive.
Every potential buyer would like to choose a gas appliance model with a reasonable price. It depends on how much power you prefer and with which functions. The more in the design of technical elements made of quality materials, the better the boiler and the higher its cost. Positive feedback received dual-wall boilers with a heat exchanger made of steel. Such a boiler can quickly heat water, weighs little and is easy to install.
What kind of gas wall-mounted boiler is better to buy? Reviews of people using such equipment testify to the simplicity of control and the ability to adjust the temperature with an accuracy of 1 ° C. In case of a malfunction of the equipment, an error code is displayed on the display.
Before purchasing a gas wall double-circuit heating boiler, prices and reviews can be clarified with the consultant of the trading organization.
When buying a boiler, you must make sure that the device is properly equipped. After unpacking, the housing of the unit should not be damaged and the operating manual should be attached to it. It is also worth checking the availability of all the component parts, so that in case of their absence, immediately contact the seller.
In addition, it is necessary to compare all the characteristics of the device on the body and packaging of the boiler. They, in turn, must comply with these indicators from the instructions.
Before installing the wall mounted gas boiler, it is necessary to contact the local gas service for approval of the installation scheme.
To ensure the combustion process, the air in the closed-type boiler comes from the street. There is no need for an individual chimney, exhaust gas is provided by connecting to a common chimney. Particular attention should be paid to ensure that the installation site does not clog the installation space of the fan. Before starting the system, it is advisable to check this place for the presence of debris and dirt.
The outside air intake pipe should be located at a height of 2.2 m from the floor and protrude from the wall at least 18 mm. To remove condensation from the chimney, the chimney pipes must have a certain slope. The gap between the pipe and the wall are subject to mandatory sealing.
The wall mounted boiler is mounted on well-fixed hooks (fastenings in the upper part of the device). The unit is installed in such a way that in the event of a malfunction service and repair can be carried out without disconnecting it from the gas and water pipeline system. It is necessary to provide on valves for water supply shut-off valves, valves, providing repair work.
Thus, wall-mounted gas boilers of a closed type can be a worthy alternative in the arrangement of an individual heating system.
