WPL 33 HT

The WPL 33 HT has a patented refrigerant circuit in which two inverter compressors can be regulated subject to demand and to achieve an optimum COP. In spring and autumn, only one compressor operates. If the heat demand increases, the second compressor is also started. In this way, the heat pump operates very efficiently in the partial load range, as only as much heating energy is made available as is required at any one time. Furthermore, the heat pump also has an intermediate vapour injection to cool the compressors at low outside temperatures and to optimise the application range. The technology that the WPL 33 HT uses is unique in the market and is already paving the way for the heating technology of the future. The advantages of output control can be put to ideal use both in underfloor heating systems and radiators. Due to a flow temperature level of up to +75 °C, there is no need for an electric booster heater for DHW heating, or the appliance can be used as a problem solver in renovation projects. The WPL can be sited almost anywhere thanks to internal and external installation versions.
