Air-to-water heat pumps (AWHPs) are an efficient and eco-friendly solution for heating and cooling homes and commercial buildings. They work by extracting heat from the outside air and transferring it to a water-based system, which can be used for space heating, cooling, and domestic hot water. These systems are highly efficient, with some models achieving efficiency rates of 250% to 400% (Daikin) (Building Energy Exchange -). AWHPs can replace traditional gas boilers and are particularly effective in moderate climates, offering both low and high-temperature options to suit various needs .
