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

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:

  • Domestic hot water tank 178 l with impressed current anode
    (flow rate 240 l - ErP 40 °C, removal of 10 l / min)
  • Heat pump controller Luxtronik 2.1
  • Energy efficient circulation pump
  • Switching valve heating and domestic hot water preparation
  • Overflow valve heating circuit
  • Electronic heating element for support during heating operation and domestic hot water preparation
    (6 kW: WZSV 62H(K)3M and WZSV 92H(K)3M; 9 kW: WZSV 122H(K)3M)
  • vibration decoupling brine and heating circuit
  • Shut-off valve for the heat source circuit
  • Heat quantity recording
  • Refrigerating circuit in module box (can be removed for bring in)
  • Free Cooling (K-series)
  • Filled with fluorinated greenhouse gas R407C


Additionally delivery:

  • Shut-off valve (fill and drain valve) heating circuit
  • Outdoor sensor


Necessary accessories:
