Field Trial of Heat Pumps Performance Assessment

This technical report presents the findings from a large-scale field trial conducted by the Energy Saving Trust to evaluate the performance of heat pumps in real-life conditions across the UK. The trial, which monitored 83 sites over a year, aimed to gather data on the technical performance and customer behavior associated with heat pump installations. The report outlines key findings, including the variability in performance among different systems, the impact of installation practices, and customer satisfaction levels. It also discusses the measured coefficient of performance (COP) and system efficiency, highlighting that well-designed and installed heat pumps can operate effectively. Recommendations are made for consumers, installers, and policymakers to improve future installations and training. The report emphasizes the importance of clear customer advice and the need for further investigation into factors influencing heat pump performance. Overall, the findings contribute to the understanding of heat pump technology and its role in reducing carbon emissions in the UK.
