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

LWCV 82R1/3

Article Number 10077041

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
