Abstract

This paper reports on experimental testing of two different heat pump systems installed in eHome2, constructed in collaboration between Saint-Gobain and Barratt Developments within Energy House 2, which is part of Energy House Labs at the University of Salford. Whilst rigorous tests of the building space heating have been carried out and reported elsewhere, no systematic tests of domestic hot water delivery by the heat pumps have been performed to date. The paper introduces tests with a fully instrumented experimental setup consisting of two different heat pumps, the eHome2, and the Energy House 2 environmental chamber. The consistency of the standardised testing protocol between the heat pumps has provided the research team with a like for like comparison of the domestic hot water heating performance. The outcome of this work will be an increased understanding of how a standardised domestic hot water demand can be fulfilled with different heat pumps.
