The STIEBEL ELTRON LWA 252 exhaust air heat pump is a compact device with heat recovery that centrally supplies homes and single-family houses with fresh air and hot water. Thanks to its compact design, it requires very little space.
Comfort features
An exhaust air/water heat pump is integrated for heat recovery from the exhaust air, which charges the hot water boiler. The parameters for the fan and the desired temperature are set using the integrated control. In addition, various time programs are available to support ventilation operation and hot water preparation, even when the occupants are away.
Efficiency
The constant flow fan is particularly energy-saving. The optimised cooling circuit improves the overall efficiency of the system. The connections for exhaust air and discharge air are located on the side or top of the unit.
Easy to install
The supply of fresh outside air is regulated by the device decentrally. The big advantage is that the majority of the air transport pipes can be omitted. In the case of a renovation, an air exhaust unit is the best solution.
