WZSV 122K3M
Article Number 10073741
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:
