The iPump is a comprehensive heat pump system consisting of indoor and outdoor units for heating, cooling and hot water supply. The outdoor unit displays a language of form inspired by modern architecture and can thus be perceived as part of a facade. Its design has also been adapted to the large U-shaped evaporator to minimise noise level. With its small footprint, it allows flexible positioning in many places and comparatively easy transportation as well. The iPump is available for brine/groundwater or air.
