WZSV 63: Geothermal heat with natural refrigerant R290
Stylish, space-saving and quiet – the WZSV 63 combines the advantages of our WZSV heating centers with the natural refrigerant R290.
The low refrigerant charge allows the ground source heat pump to be installed without additional exhaust air piping. The hot water tank, cooling* and extensive hydraulics are already integrated and can simplify installation.
The extended source temperature range allows the use of different heat sources such as geothermal probes and ground collectors, groundwater, ice storage, wastewater or PVT collectors.

Key facts
- Natural refrigerant R290
- No exhaust air piping necessary for the refrigerant used
- Flow temperature up to 75°C
- Extended source temperature -13°C to +30°C
- Compact dimensions
- Very quiet operation
More comfort. Efficient operation. Flexible use.
The new WZSV 63 ground source heat pump operates particularly quietly, features an elegant, compact design and, with the WZSV 63K1/3M model, also provides cooling in summer.
With the natural refrigerant R290 and energy efficiency class A+++ at 35 °C and 55 °C, the WZSV 63 combines high technical efficiency with flexible application options. In combination with photovoltaics and dynamic electricity tariffs, self-generated or price-dependent electricity can be used for heat pump operation.
The integrated electrical anode reduces maintenance requirements for the hot water tank.
