The WPL E series of heat pumps are suitable for both new build and renovations. The intermediate vapour injection means a high flow temperature and exemplary heating output are achieved even at low outside temperatures. Even at -20 °C, the WPL still reaches flow temperatures of +60 °C. This ensures efficient heating and hot water operation throughout the year. The lower the required flow temperature, the higher the efficiency of the heat pump. The distance between the fins of the evaporator, the heating of the condensate pan via the refrigerant circuit, and the control of the refrigerant circuit reversal enable optimum defrosting and therefore efficient operation.
Product Details
Air | water heat pump with enhanced vapour injection. Available as an outdoor or indoor installation version with corresponding accessories. The robust metal casing is made from galvanised, powder-coated and stove-enamelled sheet steel. The refrigerant circuit is hermetically sealed, tested for leaks at the factory and filled with safety refrigerant R407C equipped with twin anti-vibration compressor mounts for reduced sound power level. Enhanced vapour injection cools the scroll compressor at low outside temperatures, thereby achieving a higher heating output. The wide fin spacing of the evaporator provides low air resistance, resulting in reduced noise and improved defrosting. The 4/2-way valve enables defrosting by reversing the circuit. Equipped with electronic biflow expansion valve with separate control unit and switching via the internal heat pump control unit (IWS), for optimised overheating protection resulting in an improved COP. Time-optimised and energy efficient defrosting by circuit reversal. Heating of condensate pan via refrigerant circuit ensures efficient defrosting. With integral heat and electricity metering via refrigerant circuit data. All safety equipment is included. WPM 3 heat pump manager (accessories) required for control.
