MIT ECODAN PUZ-WM112YAA-BS 11.2KW 3PH

The Mitsubishi Electric Ecodan PUZ-WM112YAA-BS is a three-phase, air-to-water monobloc heat pump designed for efficient space heating and hot water production in residential and light commercial applications. With a nominal 11.2 kW heating output, it delivers reliable performance while keeping installation straightforward thanks to the sealed monobloc design (refrigerant circuit is contained within the outdoor unit).

This outdoor unit uses inverter-driven technology to modulate output and improve energy efficiency. It connects directly to the hydronic heating system (radiators, underfloor heating, or fan coils) and is compatible with a wide range of Ecodan cylinders and controls. The R32 refrigerant helps reduce environmental impact compared to older refrigerants, and the three-phase power supply supports stable operation on larger installations.
