Wall-mounted gas boiler and its features: TOP 10 models from leading manufacturers

In small households and country houses there is often a need to arrange a special room for gas equipment. As a rule, heating units in such buildings are located not in separate boiler rooms, but inside the house.

In this situation, it is best to use a wall-mounted gas boiler as a heat source. Such units are small in size, you can simply hang them on the wall in the kitchen, they will not interfere and will not worsen the appearance of the room.

Features of wall-mounted boilers

In terms of design features, gas boilers have much in common with heating devices operating on other types of fuel, but they also have differences.

Design

Wall heaters are a complex of sensors, instruments and devices assembled in one housing.

Units of this type have the following design:

1. Gas-burner. It consists of several tubes with slot-shaped nozzles, assembled into a rectangular contour. This arrangement of nozzles promotes uniform and efficient combustion of gas.
2. Combustion (combustion) chamber. Designed for gas combustion. It contains the burner and heat exchangers. It can be open or closed.
3. Heat exchanger. It heats the liquid due to the heat generated by the combustion of gas. In the heat exchanger, water begins to move through the heat supply pipes.
4. Circulation pump. Helps the coolant move in the heating system.
5. Expansion tank. Carries out the selection of excess coolant when it is heated.
6. Device for removing combustion products. In boilers with natural circulation, it is a pipe that connects the combustion chamber to the chimney. For turbocharged boilers, a coaxial pipe with a fan is installed, which removes exhaust gases.
7. Electronic module. Using a set of devices and sensors, it controls the operation of the boiler according to the selected program. The built-in self-diagnosis system detects problems with the operation of the boiler and displays information about them on the display in the form of a code.

Advantages

A wall-mounted gas heating boiler has a number of advantages - this explains the increased demand for such models.

Pros:

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

Flaws

When operating wall-mounted units, there are some difficulties that must be taken into account.

Flaws:

1. The need to obtain permits for the use of gas equipment.
2. The devices do not work during a power outage.
3. Relatively low power.
4. Increased demands on the quality of the coolant compared to floor-standing models.
5. High sensitivity to voltage surges.
6. The need for a mandatory protective grounding device.

Who is it suitable for?

Gas heaters are used in places where there is access to a natural gas pipeline. The operation of gas equipment is much more comfortable and economical than the use of heating units using other types of fuel.

Currently, the power of wall-mounted models produced ranges from 12 to 42 kW, which is enough to heat private houses and apartments with an area of ​​30 to 500 m². If there is only a need for heating, you can choose a single-circuit unit.

In order to provide housing with hot water for domestic needs, many models of wall-mounted boilers with two heat exchangers are produced. The devices are compact and do not require a separate room for installation; their use is optimal for small private houses and apartments.

Equipment difference

The two boiler options mentioned above (single-circuit and double-circuit) are just enlarged characteristics of a wide range of gas equipment. They are taken as an example due to the fact that the installation of such a gas boiler can be done with your own hands. Other options for gas heating devices will require the involvement of professionals. Fortunately, now it’s not difficult to find a specialist for installation. They will prepare the room and complete the documentation.

Boiler for hot water supply

Such equipment is often called a “water heater”. At their core, they are actually simple in design. There is nothing except the heat exchanger and burner. To work, you need to connect a gas and water hose to it, and also equip a chimney. Nothing more will be needed. Of course, you should not forget about obtaining permits for connecting a gas boiler. Otherwise, there is a risk of receiving a serious fine.

Boiler room for home

Double-circuit gas equipment with automation is produced so well-developed that the installation process is exactly the same as for a simple water heater. The presence of automatic control is due not only to the ease of installation and installation. It is able to control the ambient temperature and adjust according to the necessary settings. During operation of such a boiler, gas consumption can be reduced by up to 70%.

But installing a gas boiler of this type has a significant drawback. If the power supply to the house is interrupted, the boiler will not work. At the same time, the circulating sediment, if present, will also stop working. You will have to take care of additional backup power supply. You can see how to choose the right electric generator here.

Types by camera type

Depending on the design of the combustion chambers, there are 2 types of boilers: open and closed.

Open

In this case, air intake to ensure the combustion process occurs from the room where the boiler is located. Such devices are also called atmospheric. Exhaust gases are discharged through the chimney.

To take in the required amount of air and ensure trouble-free operation of the boiler, a ventilation pipe is usually installed, located in the same casing as the chimney. The height of the structure must be higher than the cut level of the roof of the house. If ventilation is poor, there may be a lack of air in the room, so the pipes need to be cleaned regularly.

Closed

Gas boilers with a closed combustion chamber are also called turbocharged. The air required for combustion is taken from the street. Exhaust gases are discharged through a coaxial pipe.

This type of chimney is a structure of two pipes inserted into one another. Exhaust gases flow out through a pipe of smaller diameter, and fresh air flows through the gap between them.

Both processes occur using a fan, which is why such a system is called a supply system. Outside air enters the chamber where the gas is burned, already heated, which contributes to a higher efficiency of the boiler. The coaxial pipe simply comes out of the wall to the outside.

The use of boilers with a closed firebox significantly reduces the requirements for ventilation of the room where gas equipment is installed. One of the disadvantages of such units is the noise that the supply fan makes during operation.

The equipment is also more expensive compared to open models. But this disadvantage is compensated by the absence of the need to install chimney and ventilation pipes.

Burner

In most cases, burners are made in the form of tubes with holes through which gas mixed with air is supplied. The burner is designed to maintain the combustion process and its intensity. The burner can be atmospheric or forced. The second type can only work with a fan, so it is noisier. However, this option is more efficient, as it allows you to regulate the air supply. Atmospheric burners are characterized by longer operation, absence of vibration during operation, and complete combustion of gas.

Types by number of circuits

Wall-mounted units are divided into single- and double-circuit. The former are intended only for heating rooms, while the latter additionally heat water.

Single-circuit

A single-circuit boiler has one heat exchanger in which the liquid is heated using heat from the burned gas. It is located above the burner in the combustion chamber and consists of a coil pipe on which a ribbed box is placed.

The materials for the manufacture of such devices are:

• cast iron;
• copper;
• steel.

The most resistant to corrosion are copper heat exchangers, but they are the most expensive. Cast iron stands are wear-resistant, but due to their fragility and heavy weight, they are usually used in floor-standing models. Wall-mounted boilers mainly use stainless steel heat exchangers.

Single-circuit units operate exclusively as heating units. To prepare hot water, it is necessary to connect additional equipment.

Dual-circuit

This heating unit has an additional DHW (hot water supply) circuit built into it. Heat exchange in it is realized in a different way - by heating one liquid from another.

The burner does not turn off. The three-way valve disconnects the primary circuit from the heating system. The coolant begins to circulate through the secondary heat exchanger, where water is heated for domestic needs.

In this case, the heating system does not function. However, a significant drop in temperature in the room is not observed, since this requires many hours of operation of the boiler to prepare hot water. In reality this never happens.

How to fit a geyser into the kitchen interior

The equipment is decorated in a special cabinet, which can be ordered from a furniture company and they will make it according to individual sketches or install it yourself.

A place for hidden placement of the boiler must be provided in advance

Boiler inside kitchen cabinet

The mechanism for making a masking cabinet with your own hands:

1. Dimensions are taken from the heating unit, and a preliminary sketch of the future furniture design is drawn.
2. Order doors from a company that manufactures kitchen modules; it is better to choose ones with an openwork pattern, this will ensure additional ventilation.
3. A sketch of the future product can be applied to the walls and unit, and guide lines can be drawn along which the cabinet will be attached.
4. To assemble the base, you need to buy profile sheets, take a screwdriver and self-tapping screws.
5. The pipes coming out of the column are hidden in a metal box.
6. The mounted profile is covered with plasterboard and the doors are attached.
7. Treat the surface with a primer and after drying, paint it in the desired color.

Varieties based on operating principle

Based on the efficiency of using thermal energy obtained by burning gas, boilers are divided into traditional and condensing.

Traditional

In traditional units, the residual heat of the exhaust gases is not used in any way, but is simply released into the atmosphere. Similar units include boilers with open and closed fuel chambers, the designs of which were discussed earlier.

Partially the residual heat is utilized in turbocharged devices, where the supply air is heated in a coaxial pipe.

Condensation

Condensing boilers, like turbocharged ones, are equipped with a closed combustion chamber and a coaxial chimney. But to extract heat from burnt gases, its design provides for the installation of another heat exchanger.

In this device, energy is exchanged between the burned gases and the coolant of the heating system. The combustion products enter the heat exchanger using a blower fan, and then the cooled air is exhausted outside through the chimney. The condensed liquid is discharged into the sewer. The coolant enters the primary circuit for further heating.

Condensing boilers have higher efficiency than traditional ones, but the complexity of the design leads to a significant increase in cost.

Extension of boiler rooms

Of course, it is very convenient to have a separate room for gas equipment, but this is not always possible, and you have to think about where to place a gas boiler in a private house under such conditions. The solution to the problem is to add a boiler room.

The standards in this case coincide with those described above, but there are a number of additional requirements:

• The boiler room can only be attached to a solid wall;
• The distance between the nearest window or door should be more than one meter;
• The boiler room can only be laid out using non-combustible materials that can last at least 0.75 hours before ignition;
• The walls of the boiler room itself must be erected separately from the main building - i.e. you will need your own foundation and four new walls.

In order for a gas line to be installed into an equipped boiler room, the building must be registered. In the absence of appropriate documents, representatives of the gas service will simply refuse to approve the equipment, even if all standards are met.

Recommendations for selection

Before you buy a wall-mounted gas boiler, you need to determine the required power for heating your home. This parameter is determined at the rate of 1 kW per 10 m² of heated area, with a ceiling height of no more than 3 meters.

Double-circuit units cope well with heating rooms and preparing hot water in households with an area of ​​up to 250 m². In large cottages, the load on the heating system is much greater, so you should use a device with one circuit, and connect special equipment to heat the water.

When installing gas units with natural ventilation, it becomes necessary to connect chimney pipes. Turbocharged and condensing boilers can be installed in any room, subject to compliance with safety standards. They have higher efficiency, but are much more expensive.

Watch a video that talks about the design features of wall-mounted gas boilers.

How big should the room be?

In a wooden house, boilers are installed at a distance of 40 cm from the walls

The dimensions of a boiler room in a private house for a gas boiler are regulated by SNiP. The parameters are determined by the power of the equipment.

The rules are as follows:

• With a power of up to 30 kW, 7.5 m² is required to equip the unit for gas. The height of the room is about 2.5 m, so when installing in the kitchen you need to calculate the air exchange rate.
• For a 60 kW heater you need 15 m³.
• The area of ​​a boiler room in a private house for a gas domestic boiler with ratings up to 150 kW is 15 m² with a height of at least 2.5 m.
• The stoker cubic capacity for a unit with a power of up to 350 kW is at least 20 m³.

In fact, the area of ​​the room should be larger. After all, service and measuring equipment must be placed next to the unit so that any elements and equipment remain freely accessible.

Size of pellet boiler room in the house

Pellet boiler room

If there is no centralized gas supply, a pellet boiler is installed instead of a gas boiler. This solid fuel option attracts with its efficiency and automation capabilities. Pellets can be stored in a special bunker, from where they are fed into the boiler as needed.

The bunker and heater are placed in different rooms or behind partitions. The dimensions of the compartments depend on the dimensions. Typically the bunker does not exceed 6 m³. This is enough to heat 400 m². within 6 months. The storage area requires an area of ​​4 m². The dimensions of the room for the boiler are calculated in the standard way.

The location of a bunker and a pellet boiler in the same room is prohibited. According to SNiP requirements, a bunker with a volume of more than 0.8 m³ is mounted in a separate compartment.

Placing the boiler in the kitchen, pantry or hallway

Boilers are allowed to be installed in the kitchen if the cubic capacity of the room is 21 m³

If the power of the device does not exceed 60 kW, installation in utility rooms in the house is allowed. Gas services allow installation if the cubic capacity of the kitchen is 21 m³ or the kitchen-dining room is 36 m³.

Both floor-mounted and wall-mounted boilers are installed here. Equipment - pumps, mixers, distributors, manifolds - usually try to be secured above the apparatus and disguised in a cabinet. Apart from the requirement of free access, there are no restrictions on installation.

The advantage of this arrangement: there is no need to lead the chimney to the roof. It is enough to bring the pipe to the facade.

Window in the boiler room

A mandatory requirement is an opening window. Its design is strictly specified by GOST R 56288-2014. The window belongs to the category of easily removable. It can be located on the wall, on the ceiling or in a pit.

Its purpose is to protect the building from explosion. In the event of an accident, the shock wave knocks out the window and, due to this, the supporting structures of the house are not damaged.

The glazing area is calculated based on the room parameters:

• if the boiler room area is up to 9 m², install a window with an area of ​​at least 0.8 m²;
• in a room of more than 9 m², the area of ​​glass - not frames, is calculated from the ratio - 0.03 m² per 1 m³.

Instead of LSK glass, it is allowed to install a single-chamber double-glazed window with a thickness of up to 4 mm. Polycarbonate, unbreakable glass, reinforced glass cannot be used.

Requirements for the door in the boiler room

The door must be equipped in the attached boiler room. From the room inside the cottage - in the basement, in the kitchen - a separate door is not needed.

The exception is a boiler room using pellets or wood. Here going outside is necessary.

The requirements for the door to the home boiler room are as follows:

• the distance from the door to the room to the entrance door should be no more than 12 m;
• the sash should open outward to facilitate exit from the boiler room;
• the width of the door leaf exceeds the width of the boiler by 20 cm;
• the leaf must correspond to type 3 with EI15 - steel door with non-combustible filling;
• the threshold in front of the entrance should be 10 cm higher than the floor in the corridor to prevent flooding in the event of a leak.

A sewer drain is installed to drain water.

Requirements for walls in the boiler room

Certain building codes are also required for attached or separate modules. Walls are constructed only with load-bearing or self-supporting materials - brick, foam concrete, aerated concrete. This material can withstand open fire for 120 or even 180 minutes.

The load-bearing load is also taken into account. The weight of boilers and expansion tanks is quite large. A brick wall will withstand such a load.
