Superior Features & Benefits

Unlike other hot water heat pump systems, the Sanden Eco® Plus system uses a smarter split system where the heat pump unit and stainless steel tank are installed separately.

This allows easy on-site handling and installation, as well as flexibility of the storage tank location, which can be up to15 metres distance horizontally or 5 metres vertically from the heat pump unit.
