LWA 403
Yielding energy from a twin pack.
The LWA 203/303 is an ideal option for heating and ventilating apartments and detached houses. The central ventilation device, with heat pump, draws energy from the extract air and feeds it back into the heating circuit. In addition, an integral air|water heat pumps yields further energy from the outside air. The recovered heat is then also used for DHW and central heating. An integral DHW cylinder provides a round-the-clock supply of hot water at a temperature of up to 60 °C. The decentralised supply of filtered fresh air is provided via valves in the external walls of the connected rooms.
