The Rheem MPi Series Heat Pump is suitable for moderate – warm climates and average size families. The new MPi Series II 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.
