The brine/water heat pump WPC/WPC cool is one of the most efficient heat pumps on the market. Since the 200-litre hot water tank with internal heat exchanger is already integrated, the pump has a small footprint. Integration of the efficient circulation pumps and the comfortably controlled WPM 3 heat pump manager creates an additional space advantage. In the “cool” option, the WPC produces a comfortable climate even in hot months. The pump draws its power for heating or cooling directly from the ground.
