* The power data at 20 (12) / 35 °C and 20 (12) / 50 °C is stated according to European standard EN255 without fans and pumps. The indicated temperatures 20 °C indicates air temperature for indoor air and (12) °C indicates the air wet temperature link.

** Delivered with 6 kW immersion heater. The immersion heater is adjustable to enable compliance with current Swedish regulations regarding newly constructed houses.

Note: When comparing with geothermal heat pumps the power consumption of the brine pump must be taken into account. A corresponding geothermal heat pump loses up to 10-20% input power and COP by pumping the refrigerant 100-150 meters up and down the borehole.
