Heating a private house (ventilation device in the boiler)

Ventilation in the boiler room consists of two parts - supply and exhaust.

Ventilation is located in the lower part of the space and should provide airflow in the quantity required for combustion in the boiler, the quantity specified in the documents on the equipment and three changes of air per hour in the room boiler.

Exhaust ventilation should provide triple air exchange. Accordingly, the selected section of ventilation pipes.

Ventilation should be natural, without fans.

 For all types of boilers, other than electric, require a chimney.

The chimney is routed to the condensate in the pipe does not flow through the joints.

Just after the boiler is a tee with ash pan and / or steam trap, which is intended for cleaning of a chimney, if necessary.

There turbo boilers and floor-turbo.

Semi-turbo forcibly emit exhaust gases through the pipe by a fan, and the air for combustion is taken from the premises.

Turbo boilers not only emit exhaust gases, but also take air for combustion. This is done due koksialnoy pipe - tube-in-tube. Outer takes the air inside emits flue gases. In this case, the chimney is not necessary to lift up the roof, over the wall to bring enough. Rules concerning the position of the chimney are specified in the passport of any product that uses them. The presence of exhaust ventilation in the room is necessary.

Chimneys and ventilation pipes may be located both inside the home and outside.

Part pipes out must be insulated to prevent creating reverse thrust, i.e. air flow in the tube from top to bottom.

 For stable thrust lifting height pipe should be not lower than the roof ridge.

That precipitation does not fall into the chimneys and ventilation channels on top of the pipes are put visors, called vane.

Passage of air or the flue gases between the tube and the cap on this area should be smaller than the sectional area of ​​the pipe itself.

To avoid inadvertent entry of flue gas into the ventilation tube in the absence of traction in it, for example, igniting the primary, closure ventilation pipes and chimneys, if they are laid in the same channel, at different make height.

On that channel everyone can share its experience in the construction, repair and improvement of your home, suburban area, send photos, tell me about your country, house, apartment. And we will tell you about my little house on the canal. Information and photos (preferably horizontal) send to [email protected]
