MIT ECODAN R290 PUZ-WZ50VAA 5KW ASHP

The Mitsubishi Electric Ecodan R290 PUZ-WZ50VAA is a 5 kW air-to-water heat pump designed for efficient, low-carbon home heating and hot water production. This compact monobloc outdoor unit uses natural R290 (propane) refrigerant with ultra-low global warming potential, delivering high seasonal efficiency and reliable performance for small to medium properties.

As a monobloc system, the outdoor unit connects to the heating circuit via water pipes, simplifying installation and keeping the refrigerant sealed outside. The inverter-driven compressor modulates output to match demand, helping reduce energy consumption and maintain comfort. Advanced controls support weather compensation and smart connectivity when paired with compatible Ecodan controllers. Suitable for underfloor heating, radiators, and domestic hot water systems, it is a versatile choice for both new-builds and retrofits.

Supplied by Mitsubishi Electric Europe B.V., the Ecodan R290 PUZ-WZ50VAA is engineered for reliability, quiet operation, and compliance with current eco-design standards. Cylinders, buffers, and accessories are selected separately to suit the application.
