Energy efficient heating and cooling
The WPL 17 ACS classic air source heat pump for hydronic heating is ideal for high-performing houses with a small heating load. Hydronic heat pumps extract energy from the outdoor air and utilise it to cost-effectively heat your home. STIEBEL's advanced inverter technology delivers all year round exceptional efficiency. Engineered for outdoor installation, the footprint of the WPL 17 ACS classic is small, meaning it can be used where space comes at a premium.
The encapsulated refrigerant circuit, as well as the acoustically isolated compressor, guarantees quiet operation. In addition, the sound of the heat pump can be further reduced by enabling the integrated silent mode function.
