Technical datasheet WPL 33 HT AIR-WATER HEAT PUMPS The WPL HT is the technological leader in the advanced air | water heat pump market. It generates high flow temperatures and is therefore suitable for radiators as well as for DHW heating. There is no need for an electric emergency/booster heater or a second heat generator. Special feature: two inverter compressors operate in one refrigerant circuit. Their speed is matched precisely to the prevailing heat demand. Other technical details also increase the efficiency and heating output, such as an electronic expansion valve which optimises the COP. And at low temperatures, enhanced vapour injection automatically improves the operating range. Subject to the system configuration, it is possible to manage without an external buffer cylinder, thanks to the integral patented cylinder. This keeps heating system modifications to a minimum. The main features Air-water heat pumps Ideal for use in older buildings Versions for internal or external installation as well as a compact version for internal use are available Automatic output matching to the heat demand of the house Energy-efficient defrosting Heating flow temperature up to + 75 °C Pasteurisation control
