High temperature series 16 kW (inverter controlled)

Using heat pumps for the modernisation of heating systems is becoming progressively easier. The new WPL HT high temperature air source heat pump extends this application range one step further still. These models are available for internal and external installation, as well as in the form of compact internal appliances with an integral cylinder. It generates hot water without a booster heater and is therefore the ideal heat pump for heating water for DHW and central heating applications. The WPL HT even achieves flow temperatures of up to + 75 °C. These high temperatures are made possible by two inverter-controlled compressors that operate in a single refrigerant circuit. Their output is always precisely matched to the current heat demand of the building. An electronic expansion valve optimises the refrigerant circuit itself. In addition, the intermediate vapour injection improves the compression process when outside temperatures are low, thereby increasing the efficiency and heating output.
