Features of wall-mounted boilers

By virtue of their design, gas boilers and heating appliances powered by other fuels share many characteristics, but they also differ.

Construction

Wall-mounted heaters are a collection of numerous sensors, instruments, and gadgets housed in a single casing.

This type of unit has the following design:

1. Gas burner. It represents several tubes with slotted nozzles assembled in a rectangular contour. This arrangement of nozzles promotes even and efficient combustion of gas.
2. Combustion chamber. Designed for gas combustion. It houses the burner and heat exchangers. Available in open or closed type.
3. Heat exchanger. It heats the liquid due to the heat released during gas combustion. The heat exchanger starts the movement of water through the heating pipes.
4. Circulation pump. It helps the heat carrier to move in the heating system.
5. Expansion tank. Carries out extraction of excess coolant during its heating.
6. Device for the removal of combustion products. In boilers with natural circulation it is a pipe that connects the combustion chamber with the chimney . For turbine boilers a coaxial pipe with a fan is installed, which removes exhaust gases.
7. Electronic module. With the help of a complex of devices and sensors controls the boiler operation according to the selected program. Built-in self-diagnostic system determines malfunctions in boiler operation and displays information about them in the form of a code.

Advantages

Wall-mounted boiler heating gas models are in higher demand because of their many benefits.

1. Compactness and modern design. The unit does not require the arrangement of a separate boiler room.
2. The use of modulating burner and circulation pump provides higher efficiency, compared to floor models.
3. High level of autonomy of equipment operation. There is no need for constant supervision of its work.

Disadvantages

There are certain challenges to wall-mounted unit operation that need to be considered.

1. The need to obtain permits for the use of gas equipment.
2. Devices do not work in case of power failure.
3. Comparatively low power.
4. Increased sensitivity to the quality of the coolant, compared to floor models.
5. High sensitivity to power surges.
6. Necessity of obligatory device of protective grounding.

For whom it is suitable

Wherever there is a natural gas pipeline accessible, gas heaters are used. Using gas equipment is substantially more cost-effective and comfortable than using heating units with other fuel types.

At the moment, wall-mounted models with a capacity of 12 to 42 kW are produced; this is sufficient to heat private homes and apartments with an area of 30 to 500 m². A single-circuit unit can be chosen if just heating is needed.

Many types of wall-mounted boilers with two heat exchangers are available to supply hot water for household needs in housing. The devices are ideal for small private homes and apartments because they are small and don’t require a separate room for installation.

Types by type of chambers

Boilers can be classified as either open or closed based on the way their combustion chambers are designed.

Open

In this instance, the room housing the boiler serves as the air intake for the combustion process. These gadgets are also known as atmospheric. The chimney serves as the exit for the exhaust gases.

Usually installed in the same casing as the chimney pipe, the ventilation pipe ensures that the boiler gets the necessary amount of air intake and operates without interruption. The structure’s height should be greater than the house’s roof cut level. In the event of inadequate ventilation, the room may not have enough air, so routine pipe cleaning is necessary.

Closed

Turbo boilers are another name for gas boilers that have a closed combustion chamber. The air intake from the street is used for combustion. Coaxial pipes are used to release the exhaust gases.

This kind of chimney consists of two pipes that are inserted one inside the other. Fresh air enters through the gap between the two pipes, which is used for exhaust gas outflow in the smaller diameter pipe.

This system is referred to as a supply system because a fan is used in both processes. The boiler operates more efficiently when outside air enters the chamber where the gas is burned after it has been heated. All that the coaxial pipe does is go outside the wall.

The amount of ventilation needed in the room where the gas equipment is installed is greatly reduced when boilers with closed furnaces are used. The noise produced by the inlet fan when it is operating is one of these units’ drawbacks.

Furthermore, the apparatus has a greater price tag in contrast to open models. However, this drawback is offset by the fact that chimney and ventilation pipe installation is not necessary.

Types by number of contours

There are two types of wall-mounted units: single- and double-circuit units. The first are solely intended to heat the space, while the second also heats the water.

Single-circuit

The liquid in a single-circuit boiler is heated by the heat from the burned gas through a single heat exchanger. It is situated in the combustion chamber above the burner and resembles a coil pipe to which a ribbed box is fastened.

The following materials are used to make these devices:

Copper heat exchangers are the most corrosion-resistant, but they also cost the most. Although cast iron is lightweight and resistant to deterioration, floor models are typically made of it because of its fragility. Heat exchangers made of stainless steel are typically found in wall-mounted boilers.

Only heating functions are performed by single-circuit units. Connecting additional equipment is required to prepare hot water.

Dual circuit

There is an extra DHW (hot water supply) circuit integrated into this heating unit. It achieves heat exchange differently, by heating one liquid out of another.

This time, the burner is not turned off. The heating system’s main circuit is cut off by the three-way valve. The secondary heat exchanger, which heats water for household needs, is where the heat carrier begins to circulate.

In this instance, the heat supply system is not operational. But since the boiler must run for several hours to prepare the hot water, there isn’t a noticeable drop in room temperature. This actually never occurs.

Varieties according to the principle of operation

Boilers are classified as conventional or condensing based on how well they use the thermal energy produced by burning gas.

Conventional

Conventional units just release the leftover heat from the exhaust gases into the atmosphere without making any use of it. Boilers featuring both closed and open fuel chambers are among these units; their designs were previously taken into consideration.

In turbo units, where the supply air is heated in a coaxial chimney, some of the residual heat is used.

Condensing

Similar to turbo boilers, condensing boilers have a coaxial chimney and a closed combustion chamber. However, another heat exchanger can be installed in order to extract heat from the burned gases according to the design.

Energy is exchanged in this device between the burned gas and the heating system coolant. Through the use of a blower fan, the combustion products enter the heat exchanger, and the cooled air is subsequently released outdoors via the chimney. The drainage system receives the released condensed liquid. In order to continue heating, the heat carrier enters the main circuit.

Condensing boilers are more efficient than conventional boilers, but they also cost a lot more because of their intricate design.

Selection recommendations

Determine the amount of space that needs to be heated before investing in a wall-mounted gas boiler. With a ceiling height of no more than three meters, this parameter is calculated at a rate of 1 kW per 10 m² of heated area.

In homes up to 250 m², two-circuit units function well for hot water preparation and building heating. The load on the heating system in larger cottages is significantly higher, so you should use a single-circuit device and heat the water before connecting any specialized equipment.

In order to install gas units with natural ventilation, chimney pipes must be connected. As long as safety regulations are followed, condensing and turbine boilers can be installed in any room. Although they are far more expensive, they are more efficient.
