MIT ECODAN R290 PUZ-WZ50VAA-BS 5KW ASHP

The MIT Ecodan R290 PUZ-WZ50VAA-BS is a 5 kW monobloc air-to-water heat pump from Mitsubishi Electric Europe B.V., designed for efficient low-carbon heating and hot water production. Using natural R290 refrigerant with a very low global warming potential, this compact outdoor unit is suitable for new-builds and retrofit projects, delivering stable performance for underfloor heating or radiators. As a monobloc, it connects to the property’s hydronic system without on-site refrigerant handling, simplifying installation and maintenance. Inverter-driven operation and weather-compensated control help optimise comfort and efficiency across seasons.
