Ventilation of the boiler room of a private house can be arranged of forced or natural type.
Features of ventilation of a boiler room in a private house
To organize natural ventilation of the boiler room of a private house, it is necessary to punch a hole facing the street in the wall above the floor opposite the boiler. The hole diameter must be at least 15 cm. To reduce the air flow, a valve is mounted on the grill. This device will allow the boiler to receive the required amount of air, drawing it directly from the street and not leading to a vacuum in the room.
But the air flow to be directed directly into the boiler room is prohibited by the requirements for boiler room ventilation.
This can be dangerous. In an emergency situation, soot and fumes from the boiler or gas (if it runs on gas) can spread through the ventilation ducts throughout all rooms of the house.
According to building codes and regulations, the ventilation requirements for the boiler room of a private house are as follows: in the furnace it is necessary to equip an exhaust duct (like a kitchen or toilet). As well as an openable window and an opening into the adjacent room, made at the bottom of the wall or door. Hole area from 2 sq. centimeters. Window area from 25 sq. centimeters. Those who install a gas boiler with a closed combustion chamber do not need to make a window, this is provided for when calculating the ventilation of the boiler room.
Many owners equip the boiler room with an additional hood, which significantly improves the convection of air flows and can be a certain guarantee of the safety of the owners in the event of boiler malfunctions.
Natural ventilation of the boiler house is very easy to install and does not require special financial investments. But at the same time, it is almost impossible to control the intensity of air blowing and blowing. The quality of the ventilation of the boiler house depends on the weather conditions.
Forced ventilation of the boiler house
It is not always possible to install natural ventilation in the boiler room. Then they resort to installing the equipment. The boiler room ventilation must be calculated by an engineer. Fans for boiler rooms operating on gas or diesel fuel should be selected explosion-proof and fireproof. The casing is made of copper or aluminum so that no sparks are generated during the operation of the equipment.
If you connect the system for turning on and off the fans to the boiler, they will turn on when the fuel equipment is started. To reduce installation costs, it is possible to equip forced air blowing or forced air blowing into the boiler room.
