ASHP Case Study No.2
Property Type:
1980s, 6-bed detached, 280 m2 floor area, timber framed with cavity wall extensions. Previously heated by an oil boiler. A wood-burning stove was retained. Property already had double glazing and 300 mm loft insulation.
Heat Pump Installation:
Daikin Altherma 16 kW ASHP, separate external and internal (including hot water cylinder) units, some new radiators. Operates at 35-45 degrees C flow temperature (weather compensated). Installation cost £13,600 in 2021 (without any grant, installed under the Renewable Heat Incentive (RHI) scheme).
Owner Experience:
How did you finding an installer?: “With difficulty! All very busy with new builds and the RHI scheme ending in March 2022.”
Installation times: “Less than 2 months from initial quote to installation. The installation took a week.”
Any installation challenges?: “The boiler was not located in a room with an outside wall, so the pipe run was more complex”
Noise: “Very quiet. Indoor unit has a pump similar to any oil/gas boiler. Outdoor unit fans run quietly even under the coldest conditions”.
