Method for heating and heating device with ventilation assembly and combustion oven

摘要

The arrangement has a controlled ventilating system (1), in which air exhaust ducts (11) deliver an exhaust air (A) outwardly from areas (K) as an exhaust air (Fo) over an air-to-air heat exchanger (10) and guide a fresh air (Fr) as supply air into the areas over the heat exchanger, where the supply air is heated by the heat of the exhaust air. A separate air duct (3) is in heat-absorbing contact with a combustion furnace (2), where a downstream end (32) of the air duct is attached at the exhaust duct, and an upstream end (31) of the air duct is open to the area.
