Completely redesigned to meet the needs of specifiers, installers and homeowners, Hitachi’s expanded Yutaki air source heat pump product range is one of the widest on the market.

Utilising common components, common outdoor units and simplified design to benefit both end users and installers, 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 for carrying multiple spares, and lowers installation and maintenance time. Performances have also been improved, with higher COPs, better seasonal efficiencies and higher capacities.

Yutaki-S has three new 4.3kW, 6.0kW and 7.5kW indoor units with dimensions of 600 x 792 x 300mm to fit a standard kitchen cupboard space. Efficiency has also been improved with COPs up to 5.25 and with an Energy Class Rating up to A+++. Yutaki-S is suitable for the heating and domestic hot water requirements of small to large properties, and is ideal for both new build and renovation projects.

The new all-in-one Yutaki-SCombi integrated solution has been designed specifically for the UK market. The indoor unit has a built-in 200 or 260L stainless steel hot water cylinder, as well as the main hydraulic components such as the pump, filter and back up heater, plus a newly-designed controller. The indoor unit is pre-plumbed and pre-wired, making the installation simpler with less internal space needed.

High temperature Yutaki-S80, which generates domestic hot water at up to 80^oC, has been completely redesigned with easier connections at the top of the indoor unit for simpler installation. Utilising Hitachi’s unique ‘smart cascade’ design, the Yutaki-S80 can be used as a replacement for inefficient boilers without changing radiator sizes or any existing hot water tank.

The all-new compact monobloc Yutaki-M requires no refrigeration pipework or internal unit. With a new controller, reduced noise levels, greater outputs up to 16kW and improved efficiencies, with COPs up to 5.0 and an Energy Class Rating of up to A++, Yutaki-M has been completely redesigned to meet the needs of the UK market.

All Yutaki models can now 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.

Talking about the benefits for end users, Andy Hooper, UK Heating Manager, Johnson Controls – Hitachi Air Conditioning Solutions said, “Yutaki has some of the best seasonal performance (SCOP) figures on the market, many models are A+++ efficient and the new wired and wireless thermostats are simple to use with weekly timers, holiday modes and a favourite button, so it’s a great product range for homeowners looking to reduce their energy bills as well as their impact on climate change.”

All Hitachi’s Yutaki air source heat pumps are MCS approved, eligible for the domestic and non-domestic RHI and have domestic hot water (DHW) Legionella Protection and a five-year warranty as standard.
