Air-source heat pumps are different to the eye

The Aerotop G air-source heat pump from MHS Boilers is described as having a radical stainless-steel design, ultra-quiet operation and an excellent COP of up to 4.7. These heat pumps are available with outputs of 7 and 10 kW and can be cascaded for larger installations. The design is achieved by arranging the evaporator in a vertical cylindrical form, enabling fan speeds to be low — resulting in an operation sound-pressure level as low as 45 dB(A).
For retrofitting applications, Aerotop G can be used with the Hidron HT, which incorporates a small water-to-water heat pump and internal buffer vessel to deliver flow temperatures of up to 70°C for heating systems with radiators. An integral DHW cylinder in the Hidron HT can deliver hot water at up to 65°C at a continuous rate of 240 l/h.
