Yutaki-S80

Hitachi’s Yutaki-S80 high temperature heat pump generates hot water up to 80°C and is ideal as a boiler replacement for heating and domestic hot water. The system utilises an energy-efficient, secondary Cascade R134a Heat Pump Circuit instead of an electrical element to provide a boost from 45°C to 80°C. This allows the home-owner or business to benefit from cost savings generated from using Heat Pump and Inverter technology at higher temperatures.

Year-round comfort, with heat output available at ambient temperatures as low as -20°C.
