Abstract
A heating and ventilating system has a space heating device, in which heat is generated by combustion of a fuel, and which heats air for a building. A heat exchanger has one side through which exhaust air from the building flows to the exterior. Through the other side of the heat exchanger, fresh, makeup air for the building is supplied, and this may pass through the heater. An exhaust conduit from the heater, for combustion products, opens into the exhaust air line connected to the one side of the heat exchanger. This enables heat to be extracted from air leaving the building and further heat to be extracted from the combustion products, this heat being transferred to the incoming air in the heat exchanger.
