Air heat pump
commotherm LWi-Split

Power range 6 till 16 kW

HEATING – COOLING – HOT WATER FROM THE NATURE

The commotherm LWi split air/water heat pump impresses with latest inverter technology. Inverter technology means, the compressor of the heat pump is modulating. The advantage is a perfect adaption of the heating output of the heat pump to the actual outdoor temperature. The inverter technology guarantees excellent energy efficiency – even at low outdoor temperatures. The heat pump can be used for heating, cooling and for domestic hot water preparation, with flow temperatures up to 55°C.
