The 55132507 is a 325L Heat Pump Hot Water Unit Mpi-325 Series II from Rheem. The MPi Series Rheem Heat Pump utilises the latest environmental heating technology to efficiently heat water. Free, renewable heat energy is absorbed and processed through a refrigeration system, resulting in hot water using a third of the energy of an electric water heater. These are similar savings to a solar water heater, but without needing panels mounted on your roof.
