SmartHeat classic i

SmartHeat heat pump series classic - more than 20 years success

Heat pumps of the SmartHeat classic i series offer unrivalled flexibility and can be used for heating, cooling and hot water preparation (with freely chosen external storage system). The SmartHeat classic units are designed for an capacity range from 2 to 33 kW, where high-efficiency compressors are the most effective solution. The SmartHeat classic i is available as brine / water as well as water / water heat pump.

Thanks to advanced inverter technology, these systems achieve excellent COP ratings while the size of the buffer storage tanks can be significantly reduced. The wide range of extras and accessories make the SmartHeat classic i one of the most flexible heat pumps in the market, as they can be adapted to meet specific project requirements. SmartHeat classic i units are therefore the preferred solution for any project from new passive energy houses to heating system upgrades.
