“Power Inverter” PUHZ-SW series air-to-water heat pumps.

For even more efficient and economical heating and domestic hot water

Thanks to the state-of-the-art technology and high-performance compressor, the new PUHZ-SW has extremely high technical characteristics and can even prepare water up to +60 Co! PUHZ-SW series heat pumps are the market leaders in terms of seasonal performance indicators and the amount of heat released at extremely low ambient temperatures.

2017 news! PUHZ-SW75YAA and PUHZ-SW100YAA series three-phase, single-fan, especially quiet (even 10dB quieter than PUHZ-SW-HA models) outdoor units.




All of outside units Puhz-SW series air-to-water heat pumps can be equipped with various internal parts: ECODAN all-in-one (EHST20C-YM9C and EHSC-YM9C) or heat exchanger.
