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.

The big advantages of the HERZ commotherm LWi-Split

  • Latest inverter technology
  • Highest efficiency in heating, cooling and domestic hot water operation
  • Flow temperature up to 55°C
  • User-friendly 7″ VGA-colour- touch control T-CONTROL II
  • High efficiency rates (COP and EER)
  • Compact design – Flexible installation possibilities
  • Easy to install and low in maintanence
  • Different color variants from the RAL color palette possible

Active cooling
During the summer months, the heat pump can also be used for active cooling in order to create a pleasant room climate. Cooling takes place via the underfloor heating or a cooling ceiling.

Whisperquiet
The heat pump ensures whisperquiet operation during the night due to the built-in silent mode. This feature reduces the sound emissions of the heat pump. It is possible to define 3 times a day for sound reduction. For additional sound reduction and weather protection the HERZ CAP is available as option for the LWi heat pump.
