The loss of heat via the external surfaces of a new building continues to decrease nowadays. However, the loss of heat caused by ventilation of the heating work to be provided continues to increase. An appropriate exchange of air is indispensable for a healthy, pleasant dwelling climate. Permanently open windows would ruin all efforts made to ensure controlled ventilation and the reduction of energy consumption.
HAUTEC exhaust-air heat pumps draw off the used air from certain rooms of the house via the dwelling ventilation. The heat stored in that used air is recovered with the help of the exhaust-air heat pump and is used all year round for hot-water production and heating purposes.
