alira - V-line - LWCV-series - compact air/water inverter heat pumps for indoor installation

LWCV 122R3

Article Number 10077141

The innovative - compact with a unique transport concept.

Operating limit flow temperature 20°C to 60°C
Recommended range of application heat source -22°C to 35°C

The heat pumps are recommended for the following total heating demand:
LWCV 82R1/3 = ca. 7-10kW; LWCV 122R3 = ca. 10-14kW

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

  • Heat pump controller Luxtronik 2.1
  • Energy efficient circulation pump heating circuit
  • Switching valve heating and domestic hot water
  • Overflow valve for the heating circuit
  • Buffer tank 82 l for heating
  • Electric heating element for support during heating operation and domestic hot water preparation
  • Expansion vessel (LWCV 82R1/3; 12 l, LWCV 122R3; 18 l)
  • Heat quantity recording
  • Vibration decoupling heating circuit
  • Filled with fluorinates greenhouse gas R410A

Additionally delivery:

  • Safety assembly heating circuit
  • Connectionset heating circuit
  • 3 shut-off valve (fill and drain valve) heating circuit
  • Outdoor sensor

The LWCV-devices can be connected on the air outlet side either on the left or right. The cooling is deactivated and can be activated at the commissioning

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.
