Johnson Controls – Hitachi Air Conditioning launch combi heat pump

Johnson Controls – Hitachi Air Conditioning, a joint venture between of two of the biggest manufacturers of air conditioning and refrigeration units in the world, is launching the latest in its award-winning range of heat pumps to the UK market – the YUTAKI S COMBI.

The YUTAKI S COMBI system is based on state-of-the-art air-to-water heat pump technology. The companies say it achieves outstanding performance in space heating as well as providing domestic hot water and it also features the added option of providing chilled water for the cooling of homes during summer months.

In addition, it can be combined with existing boilers for installations where temperatures as high as 80°C are required on the space heating circuit.

Martin Richards, UK & Ireland national manager at Johnson Controls – Hitachi Air Conditioning, said: “Heat pump technology is still the most viable means of providing energy efficient and cost effective heating and cooling in domestic buildings. The new YUTAKI S COMBI has the potential to be the most effective and efficient all-round heat pump solution on the market to date. We are confident it can contribute towards a revitalisation of renewable heating technology installations in the domestic sector.”

Every 1kW of electricity used to power the YUTAKI S COMBI can yield up to 4kW of energy for heating, providing savings of up to 80% on heating expenses compared to a traditional fossil fuel boiler.

The units are also easy to install and operate. They are composed of an outdoor unit and a new all-in-one indoor unit featuring a built-in domestic hot water tank. At just 600mm in width, the system will fit into kitchens and utility rooms with ease. The hydraulic components used to provide space heating and domestic hot water are built into a mono-bloc indoor unit – consequently reducing the amount of work required for installation.

For the end user the system is simple to control thanks to an intelligent and intuitive LCD display module. The controller enables the user to quickly monitor comprehensive parameter and status information, such as energy consumption, capacity data and water flow.

The wide YUTAKI S COMBI range features 2HP to 6HP versions and the possibility to choose between: Reversible models (heating and cooling) or heating only models and two tank capacities (200/260 L), both fitting into a common design of the unit.

The domestic hot water tank is built from advanced materials to achieve the highest possible thermal efficiency – including mould-injected Neopor EPS insulation, and chemically descaled stainless steel passivated materials.

In accordance with the shift towards environmentally-friendly gas refrigerants, the YUTAKI S COMBI uses R410A – which features an ODP (ozone depleting potential) of zero. In addition, RoHS and Green Dot regulations were used throughout the R&D and manufacturing processes.
