What is Hitachi Yutaki?
Yutaki is Hitachi’s flagship air-to-water heat pump range, designed for both new builds and retrofits in the UK.
What are the benefits of Hitachi Yutaki heat pumps?
Yutaki heat pumps deliver efficient heating, cooling, and domestic hot water, with models that qualify for UK incentives like the Boiler Upgrade Scheme.
Are Yutaki heat pumps suitable for cold climates like the UK?
Yes, Yutaki models are engineered to perform in low temperatures, ensuring reliable comfort even in winter.
What does "split system" mean in HVAC?
A split system consists of two main components - an indoor unit and an outdoor unit, connected by refrigerant piping. They’re common in both residential and light commercial settings.
What is an air-to-water system?
Air-to-water heat pumps use outdoor air to produce hot water for heating or domestic hot water supply, offering an efficient and green alternative to traditional boilers.
What’s the difference between R410A and R32?
R410A has been widely used for years in HVAC systems, but it has a higher GWP compared to R32. Many new systems now transition to R32 for improved energy efficiency and to meet stricter environmental regulations.

Single-phase systems are common in UK homes and small businesses, while three-phase systems are designed for larger commercial or industrial applications where higher power and efficiency are required.
