The Ecodan is a domestic air source heat pump produced by Mitsubishi Electric.
The Ecodan range comprises four models: 5 kW single phase, 8.5 kW single phase, 14 kW single phase and 14 kW three phase. The Ecodan utilises a refrigeration circuit with a compressor and condenser and uses inverter-driven - as opposed to fixed-speed - technology.
