WPL 57 Air Source Hydronic Heating Heat Pump

The WPL 57 can be cascaded for use in large buildings or commercial units. Up to six systems can be used to easily multiply the heating output. All the while, the operating noise is kept to a minimum by an encapsulated refrigerant circuit, an acoustically isolated compressor and wide gaps between the evaporator fins. Both the corrosion protected metal casing painted in STIEBEL white and the casing protecting the evaporator ensure high durability of the outdoor elements.
