Mitsubishi 14kW R32 3Ph Mono ASHP Outdoor Unit Coastal Zubadan

The Mitsubishi PUZ-HWM140YAA-BS - 14kW R32 3Ph Mono ASHP Outdoor Unit Coastal Zbdn Cylinders is a high-efficiency three-phase monobloc air source heat pump designed for space heating and domestic hot water applications, featuring Zubadan technology for reliable performance in low temperatures and coastal protection for enhanced durability.

Product Description

The Ecodan PUZ-HWM140YAA-BS is Mitsubishi Electric’s advanced R32 monobloc air source heat pump, offering ultra-quiet operation, compact design, and superior energy efficiency. It maintains full heating capacity even at -7°C and operates down to -28°C, making it suitable for UK climates including coastal areas. The -BS variant provides additional corrosion resistance, ideal for installations near the sea. This self-contained outdoor unit requires only water and electrical connections, eliminating the need for gas supplies or indoor units, and is compatible with various cylinder sizes for hot water storage.
