The Swedish heat pump manufacturer Jifon AB in Sösdala launches AirGo™, a heat pump taking energy from both soil and air! The hybrid solution with a copper coil in the ground (1m below ground with a loop length of 15-30m) combined with a quite air collector, AirGo™, provides a unique advantage over existing solutions. The air collector is fan-less and therefore there is only one moving part, the compressor. This unique design ensures a highly economical and reliable solution for heating. Moreover, the installation of AirGo™ is very simple, either drilling or major excavation work is necessary and therefore is ideal for use even in smaller plots.
