Getting warmer: a field trial of heat pumps

By Robin Roy, Sally Caird and Stephen Potter

Abstract

Given the lack of data on heat pump performance in customers’ homes, the Energy Saving Trust in partnership with the Open University undertook the first large-scale heat pump field trial in the UK to determine how heat pumps perform in real-life conditions. The year-long field trial monitored technical performance and customer behaviour observed at 83 sites across the UK. The findings provide valuable information about the factors that affect the success of a domestic heat pump installation. Instead of revealing outcomes along statistical grounds, or acting as a “brand-vs-brand” competition, the field trial findings provide a discussion of key points of interest to potential consumers, including:\ud • Measured coefficient of performance (COP) and system efficiency\ud • Installation practices (both system design and performance)\ud • Customer behaviour (contribution by the Open University)\ud • Heating patterns and average internal temperatures\ud • Economics\ud This report makes recommendations for consumers, installers, manufacturers and policy makers, and identifies areas that require additional investigation and research
