Product Description

Key Features:

  • Monobloc heat pump
  • Can stand alone from the building
  • LW 121A/SX is MCS approved
  • X models have corrosion protection coating

With a heat output of 12.1 to 35 (kW) and a COP of 3.7 to 4.3, the LW heat pump range is the latest in air source technology. The LW can be used with solar thermal, hot water and ventilation systems, making it the perfect partner for all OMNIE underfloor products.

The heat pumps can be located away from the building installed on a concrete base. The units themselves are extremely quiet (51 to 59 dB(A)@1m) meaning that it will be discreet and unobtrusive.

The heat pump fins have corrosion protection whilst the heat pump uses the same standard Lux controller as all Alpha-InnoTec heat pumps. AlphaWeb is provided as standard for all heat pumps to allow remote connection of the heat pump for control, diagnostics and troubleshooting.
