Air-to-Water Heat Pumps for Year-Round Comfort with Hitachi
Hitachi offers a comprehensive range of air-to-water solutions, including both regular and high-temperature heat pumps, monobloc heat pumps that don’t require installation of indoor equipment, combi heat pumps that integrate a water storage tank, and hydro-split solutions designed especially for boiler technicians to install without needing to handle refrigerant.
Connect to existing or newly-installed under-floor heating and radiators to deliver heat, or use our range of fan coils for a year-round integrated heating and cooling solution.
Hitachi’s complete portfolio is easy to integrate, set up and maintain, and offers remote management via a smartphone app.
– Hitachi's Air-to-Water Heat Pumps have a wider ambient operating temperature
Continued operation in the harshest of winters, supporting hot water outlet temperatures of 52°C in outdoor temperatures down to -25°C, or maintaining 60°C hot water output in conditions as low as -10°C. High-temperature heat pump models can maintain 80°C hot water output in ambient conditions down to -20°C.
– Efficient space Heating & Cooling with fan coil units
Homes without existing pipework or underfloor heating, or where it may be difficult to install underfloor heating, can deliver space heating and cooling through our range of fan coil units which blow air over water pipes. Unlike radiators they can be used for both cooling and heating and are effective for heating without need for a high-temperature heat pump.

– Just 3hrs to heat a full tank of water
One of the fastest water heaters on the market - heat a complete tank of water at up to 55°C (75°C with electrical back-up) in just 3hrs[1]. Supports water output temperatures from 30- 75°C.
– Silent and compact designs that fit in a standard kitchen cupboard
Our portfolio includes hot water tanks that operate silently and are only 60cm wide, enabling placement in a standard kitchen cabinet.
– Easy installation & maintenance access with simplified pipe layout
The filter valve allows quick cleaning without draining the installation. All the water and refrigerant piping connections are perfectly aligned in the upper section, while most components can be accessed from the front.
