The outdoor unit includes a heat pump, which extracts heat from the ambient air and transfers it to the indoor unit via refrigerant piping. The unit is compact and easy to install.

This system has a reversible cycle, which allows it to both extract and insert energy in order to cool or heat with the same system, controlling the starting, stopping and reversible cycle automatically. Thanks to its versatility it is possible to use these heat pumps which are able to heat a pool as well as control the temperatures in a greenhouse.
