alterra WZSV-series – ground source inverter heatstations for indoor installation

The space saver - the entire heating system on half a square meter.

Operating limit flow temperature 20°C to 65°C
Recommended range of application heat source -5°C to 25°C

The heat pumps are recommended for the following total heating demand:
WZSV 62H(K)3M = ca. 3-6kW; WZSV 92H(K)3M = ca. 6-9kW; WZSV 122H(K)3M = ca. 9-14kW.

For faster installation, the system comes with the following components:

• Domestic hot water tank 178 l with impressed current anode
  (flow rate 240 l - ErP 40 °C, removal of 10 l / min)
