How do I prevent a partial vacuum in the room?
Excess smoke can occur when there is a partial vacuum in the room in which the wood-burning stove is located. This can be caused by heat recovery in low-energy houses or with powerful suction from exhaust hoods.
If this happens, smoke will come out into the room when the door is opened because of the excess pressure in the wood-burning stove in relation to the room in which the stove is located. In this situation, it is necessary to get the house pressure-equalised, in which the partial vacuum in the house does not exceed 4 Pascal.
