Hitachi claims new high for heat pump water temperature

Hitachi claims its new Yutaki-S80 offers the hottest water temperature for a domestic  heat pump, providing up to 80 deg C.

The air to water heat pump already claims the highest COP on the market of 5.0, Hitachi says, but its twin compressor system running with both R410a and R134a in a ‘smart cascade’ enables the water temperature to be boosted when required.

The manufacturer says the Yutaki-S80 will be ideal for existing properties, in particular older establishments where higher water supply temperatures may be required to keep the house warm – as well as for new builds. It is designed for boiler substitution, offering heating and sanitary hot water all year round, without boiler back-up.

The split system uses Hitachi’s IVX outdoor unit with a newly designed standalone indoor unit, manufactured in Hitachi’s purpose-built factory in Spain.

Six different models, covering a range from 10 to 16 kW are available in single phase or three phase versions. The indoor unit is a standard width of 600 mm allowing seamless integration into kitchens and utility rooms and includes a 200 or 260-litre SHW tank.

The system is simple to control, says the firm. Its wireless remote controller is a variation of the well-received and successful design used with the existing Yutaki-S system, which includes a helpful LCD graphic display, one-touch holiday button, weekly timer and frost protection.
