Hitachi Yutaki S Combi air source heat pumps transform the air outside your home into usable heat through refrigeration and vapour compression.
You would typically need a dedicated heat pump hot water cylinder with a larger coil surface area to complement your unit. This is also available through Hitachi, but the Combi offers an all-in-one pre-plumbed and pre-wired system.

Several other heat pumps are comparable to the Hitachi Yutaki S Combi in terms of price and performance.
If you are interested in a high-performance unit that works well in low temperatures, you should consider the Hitachi Yutaki S80. This model can heat water up to 80 °C at −25 °C and offers outputs of 32 kW with an A+++ efficiency rating.
If you don’t want to stick with the Hitachi brand, however, you could consider the LG THERMA V. We were impressed with its powerful 16 kW output, favourable price tag and compact design.
You might get better results from the Daikin ALTHERMA 3 if you live in a very cold climate. This heat pump can handle temperatures of −25 °C with ease (although it is more expensive).
We can also recommend Mitsubishi Ecodan Monobloc heat pumps which are comparable to the Hitachi Yutaki S Combi in terms of efficiency and performance.
