alterra WZS-series – ground source heatstations for indoor installatiom

WZS 42K3M

Article Number 10066541

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:
WZS 42H(K)3M = ca. 5 kW; WZS 82H(K)3M = ca. 8 kW; WZS 102H(K)3M = ca. 10 kW; WZS 122H(K)3M = ca. 12 kW

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 heating circuit
  • Switching valve heating and domestic hot water preparation
  • Overflow valve heating circuit
  • Electronic heating element 9kW for support during heating operation and domestic hot water preparation
  • 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 R410A


Additionally delivery:

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


Necessary accessories:

  • Safety assembly and expansion vessel for the heating circuit
  • Safety assemly and expansion vessel for heat source circuit

The operating instructions of the functionally necessary accessories such as hydraulic module or hydraulic station are stored in the "Downloads" tab under "ACCESSORIES".


* The data are only recommendations. Depending on individual circumstances, a heat pump with a lower heating capacity may also be suitable for larger buildings and vice versa. In addition, it is possible to connect several heat pumps together and thus increase the heating capacity. Finally, a precise individual calculation is required to select the really suitable system for the project.
