Where to locate the boiler room?

In theory, the boiler room can be located anywhere in the house. In practice, however, it is worth locating it on the lowest floor (for example, in the basement), possibly in the center of the building . What speaks for such a location?

  • Heat always flows upwards, so you can count on the fact that a boiler room generating high temperatures will naturally heat the rooms above it.
  • The reason for locating the boiler room between other rooms is the equal distance of all radiators from the boiler. This solution avoids heat loss.

What dimensions should a boiler room have?

The boiler room is a purely utility room. Therefore, many people would rather not waste valuable space on them. However, its dimensions are regulated by specific regulations, and more specifically, they must meet the requirements of the Heating standard. Solid fuel boiler rooms. Requirements. PN-87/B-02411.

First of all, you need to ensure the correct height of the room. It should not be lower than 2.2 m . If the heating installation is reorganized in a house that did not previously have a boiler room, the boiler must be placed in a separate and appropriately adapted room with a height of at least 1.9 m . Providing it with adequate ventilation will be key.

The distances separating the boiler from the walls will also be very important. It is worth remembering that convenient access to the device should be provided from all sides. The required space at the back is at least 0.7 m, on the sides - 1 m, and at the front - at least 2 m. So, as you can see, the boiler - depending on its size - may require about 10 m 2 of space .

What else should you remember when designing a boiler room?

  • The supply ventilation opening should be at least 200 cm 2 and cannot be closed or covered. It must be a maximum of 100 cm above floor level.
  • The combustion chamber of a 25 kW boiler requires an air supply of 1.6 m 3 /h for each kilowatt.
  • In the case of a gas boiler, the height of the ventilation grille should be limited to the level just above the floor. This is due to the properties of liquid gas, which after expansion has a greater weight than air, so it lies low above the floor.
  • You also need exhaust ventilation, which must be made of non-flammable materials and located just below ceiling level. The minimum dimensions of its opening are 14 x 14 cm.

What devices, apart from the boiler, should be in the boiler room?

The foundation of all boiler rooms are heating devices. You can choose from a solid fuel, gas or oil boiler. Most often, they are equipped with the necessary accessories, such as safety valves or expansion vessels. Any components not supplied in the kit are usually mounted close to the boiler to create a compact and flawlessly functioning structure.

It is best to choose condensing boilers with a closed combustion chamber. They are more economical because they obtain additional heat from exhaust gases. In models with an open combustion chamber, it escapes irretrievably through the chimney. However, the heating device is only the basis of the boiler room. It should also include products such as:

  • domestic hot water tank,
  • expansion vessels - for central heating and domestic hot water,
  • pumps - used for central heating circulation, supplying circulating water and loading the tank,
  • filters - on the supply line to the boiler and the return line, and in the case of a gas boiler, also a gas filter,
  • valves - including non-return, shut-off, hot water and boiler safety, drain, mixing and anti-pollution valves; their number and specific types depend on the configuration used in the room,
  • thermometers and manometers.
