Redesigned to meet the needs of specifiers, installers and homeowners, Hitachi has launched its expanded Yutaki air source heat pump product range.

Using common components, common outdoor units and simplified design, the extended line-up includes a total of 70 new models, which are more compact for small installation spaces and are lighter weight for easier handling. The introduction of common components and controllers streamlines product training requirements, reduces the need to carry multiple spares and lowers installation and maintenance time. Performances have also been improved, with higher Coefficients of Performance, better seasonal efficiencies and higher capacities.

Yutaki-S has a new 6kw outdoor unit as well as three indoor units (4.5kw, 6kw and 7.5kw) to suit the heating and domestic hot water requirements of small to large properties and is suitable for both newbuild and renovation projects.

The all-in-one Yutaki-S Combi also includes a new 6kw model and a solar version with integrated 260-litre domestic hot water (DHW) tank, featuring solar coils designed specifically to be ‘ready to use’ with solar panels.

The high temperature Yutaki-S80, which generates domestic hot water at up to 80°c, now includes two specific indoor units to be used either standalone (with top pipe connections) or with an optional 200-litre or 260-litre DHW tank, with rigid pipe connections to the rear of the unit.

The monobloc Yutaki-M, which requires no indoor space, now shares many of the same components and controllers as the splits in the range for simplicity of installation and maintenance. All Yutaki models can be supplied with a new Cooling Kit accessory to enable both heating and cooling modes.

A new multi-function wired remote control is common to all Yutaki models – meaning a single menu for all Yutaki products with a dedicated installer view, wizard start up configuration and a more intuitive menu for quick and simple commissioning. The alarm history is also logged to assist engineers with troubleshooting.

All Hitachi’s Yutaki air source heat pumps are MCS approved, eligible for the domestic and non-domestic Renewable Heat Incentive and DHW Legionella Protection, and a five-year warranty as standard.
