  [(Useful data analysis / cleansing detail.) Quote: "Measured real-world performance of Air Source Heat Pumps (ASHPs) has increased significantly compared to data from past field trials. Heat pumps performed well even on the coldest observed days, with only a relatively small reduction in performance. High Temperature ASHPs had comparable efficiencies to Low Temperature ASHPs, indicating that they are a viable solution to reduce home retrofit requirements." Quote: "The median SPF observed in ASHP systems during the EoH Demonstration Project was 2.80 (280%) [at the H4 boundary]." Quote: "However, whilst the average performance has improved, performance variation remains high." Quote: "High Temperature ASHPs - those which can achieve flow temperatures similar to that of a gas boiler - are a viable solution for meeting the heating demand of a property. Use of High Temperature units reduces the need for deeper retrofit and provides a potential solution for less efficient homes. The data released by Energy Systems Catapult demonstrates that the High Temperature ASHPs used in the Project have performed with similar efficiencies to Low Temperature ASHPs. Heat pumps are controlled to only demand higher temperatures when it's colder outside." Quote: "All homes with heat pumps installed through this project were deemed suitable for an installation by trained designers and installers. ... the results may not be representative of the whole UK housing stock."]
