The benefits of advanced heat pump technology are multiplying. The WPF series of heat pumps was developed specially to supply larger residential complexes as well as commercial and industrial buildings with heat. On request including DHW provision. Cascade control enables one or more units to provide the base cover for heat; peak loads are covered by starting additional units. This clearly reduces running costs. When several units are used, two heat pumps can be stacked to save space. This way, heat pump systems not only save energy but also space.

Comes with a FREE ISG Web Interface (Internet Service Gateway) – Allows communication with your heat pump remotely via a Smartphone Web app and also allows communication with the Stiebel Eltron Customer Service Centre.
