Application • This compact ground source heat pump with output-dependent control, inverter technology and integral DHW cylinder is installed indoors. The high level of integration facilitates installation. Does not take up much space thanks to the small footprint. • The heat pump can be used for modernisation projects as flow temperatures of up to 75 °C are available all year round for room heating and DHW heating. • An intermediate heat exchanger is incorporated for energy efficient passive cooling via the underfloor heating system. • Mono mode is possible for both heating and DHW heating. 

Convenience features • Very quiet operation is ensured by the encapsulated refrigerant circuit and acoustically isolated compressor. • The heat pump offers demand-dependent fully automatic control. • If the integral heat pump manager is connected to the Internet Service Gateway, the system can be integrated into a smart home network and controlled via a mobile device. • With integral heat and electricity metering via refrigerant circuit data. • One high efficiency circulation pump is built in for the brine side and one for the heating side. • Electric emergency/auxiliary heater for mono energetic operation and pasteurisation. • Diverter valve for DHW heating and safety valve with drain pipe. • The refrigerant circuit works with the eco-friendly, futureproof refrigerant R454C, which has excellent properties in heat pump application. • The corrosion-protected casing is made from hot-dip galvanised, powder coated sheet steel.

Efficiency • Thanks to the energy saving inverter technology and integral recuperator, the heat pump works efficiently all year round.

Installation • No special safety precautions are required when siting. A minimum room size must be ensured. • To facilitate installation, the refrigerant circuit can be easily separated from the cylinder module. Both parts have integral carrying handles. • The supplied pressure hoses enable direct hydraulic connection to the heating side and source side.
