These small units heat water, which is then distributed via pipes to radiators or underfloor heating systems to give your house warmth. Wall gas boilers save important floor space and have a sleeker appearance than traditional boilers, which are frequently large and take up a lot of room.

It’s critical to determine the model of wall gas boiler that best meets your needs by evaluating the heating requirements of your house before making a purchase. Take into account variables like your budget, the number of rooms you need to heat, and the size of your property. Make sure the boiler you select meets safety regulations and works with your current heating system and gas supply.

After deciding which wall gas boiler is best for your house, the installation procedure can start. Make sure you have all the equipment and supplies you’ll need, such as insulation, fittings, valves, and pipes, before moving forward. Additionally, it’s a good idea to have someone on hand to help lift and move the boiler into position.

Wall gas boiler installation entails a few crucial procedures, such as securing the boiler to the wall, attaching it to the water and gas supply pipes, and setting the controls for maximum efficiency. Although the process might differ slightly based on the model and design of your home, it usually follows a standard procedure described in the instructions provided by the manufacturer.

Norms for installing gas hinged boilers

Regulations exist that specify the installation-related construction guidelines.

You must first meet all requirements listed in these documents:

  1. Call to the gas workers so that the experts check the existing conditions and, in the case of compliance with the rules, allow the unit unit to the central highway of the house.
  2. Correct a project to avoid a fine. The exception – the heat generator has already been mounted in the house and it is only necessary to replace it with an identical model.

After the project is finished, documentation must be sent to the state oversight agencies. They check and then grant permission to install a wall boiler.

Next, a few more prerequisite conditions must be met: pick the appropriate height and adhere to the guidelines. safety.


You have to follow the guidelines in the joint venture for choosing the ideal height when mounting a boiler on the wall. It specifies that there should be a minimum indication of 0.9 meters, but no more than 1.2 meters, between the floor and the bottom of the purchased boiler. Although gallows frequently present these requirements in a similar manner to boilers, it is important to note that these parameters are used for boilers.

The minimum height required by gallmakers, which is determined by the distance from the chimney pipe, must be adhered to. According to official standards, the wall-like apparatus must have a minimum indicator diameter of two diameters for the chimney.

Fire safety standards for installation

When installing the wall-mounted gas boiler in the apartment, PB regulations must be followed.

As a result, fire breaks must be installed (the following minimal indicators are listed and should be adhered to):

  1. Distance from equipment to the wall – at least 10 cm.
  2. From the opposite wall – at least 40 cm.

The installation of a thermo-insulating shield and wall attachment for equipment is mandated by the fire safety regulations. He needs to be found under a gas boiler right away. Fire breaks must also be installed if the chimney must be mounted through the roof.

A non-combustible, protective partition must be placed between the residential area and the room housing the wall-mounted boiler with a single circuit. For home safety, it ought to have a higher level of fiery resistance. Use corrugated metal pipe when connecting equipment. Purchasing rubber hoses to install the boiler is strictly prohibited.

Installation on different walls

Because of their considerable weight, boilers can cause issues if the wall’s fixation is not considered reliable. Boiler installations are subject to certain standards, which specify that installation work can only be done on solid walls.

Depending on the material that was used to build the house’s walls, requirements can differ significantly. There are standards for brick, wood, drywall, and reinforced concrete surfaces.

Installation on the Wall Wall

The best options for wall gas boiler installation are reinforced concrete walls. They are entirely non-flammable and stronger than before. As a result, no additional cladding or protective measures were employed. Metal anchors are used to secure the heat generator housing, and the mounting bar is fixed on top of them. The unit is then installed on the site after it has been ready. Any type of heating system, including a large power or regular cumulative broiler, can be installed on concrete walls.

Installation on a brick wall

The requirements for fastening to the brick wall are specified separately in the installation norms. Since brick is another premium non-combustible material, the equipment is mounted on the wall right away; however, you must prepare the surface in this case.

The wall needs to be plastered in order to comply with gazmiers’ requirements prior to installation work. You will need to mount a special bar while doing these repairs. Once the plaster is finished, there should be two bolts protruding from the wall to act as a landing area for equipment.

Is it possible to hang a boiler on a wooden wall

Because of several subtleties, installing a wall gas boiler in a wooden house is a challenging task. Because wooden walls can catch fire, you must take precautionary measures.

You must meet a few requirements in order to install the heating boiler correctly:

  1. Thoroughly treat the tree at the installation site. It is quite simple to do it with your own hands – there are special antipyrines in construction stores. They will need to abundantly process the wall.
  2. Pre -prolong the wall with plaster (thickness – 15 mm). This is the minimum value that guarantees protection against high temperatures. You can also clad the wall with roof steel.

In the event that plaster or metal cladding are not desired, a gypsum accommodation plate can be installed where the heat generator is fastened, followed by ceramic tile covering.

In order to prevent a heavy heating boiler from toppling over its installed location, the site must be reinforced with a strong beam positioned beneath the facing material. Consequently, the heat generator will be able to be fixed on the wall with reliability.

Is it possible to hang on drywall

It is impossible to completely prevent voids when installing drywall. This causes issues with a heavy heat generator’s fastener. There is a way to get rid of this flaw, though.

When a metal frame is made, it is required to plan ahead and do preparatory work in order to determine where the boiler will be fixed. The site must be consistently strengthened with a metal profile and a wooden beam. Special latches are used during installation on drywall that is brittle. These plastic plugs are inserted into the facing material by screwing them in. Metizes need to be installed in the established cork already. According to experts, prefabricated fasteners are progressively trembling, which deteriorates fixation.

Pencounton and aerated concrete boiler mount

There are various ways to install the boiler if the house is made of foam or aerated concrete:

  1. Fasteners are installed in advance at the moment when the blocks are laid. The installation of the boiler is carried out when the masonry mixture completely hardens.
  2. In stores you can find raids for fixation in foam concrete. They are very similar in traffic, used to work with drywall. But they have a deeper thread and a greater step. As soon as the material is screwed into foam concrete or aerated concrete, any anchor that will reliably hold gas equipment can be installed in the rains.
  3. Another reliable way to fix it is with hairpins. They are installed with a small interval from each other, and in the wall (on each side) the bar is mounted, which is tightly fixed with bolts for maximum reliability.
  4. You can also use liquid, chemical anchors. They provide strong fixation, but are more expensive than previous options.
