Buildings account for as much as 50% of the total energy consumption in the UK. The UK government is committed to reducing carbon dioxide (C02) emissions by 20% by the year 2010. The proposed project aims to investigate a GSHP system that utilises grey water as a heat source/sink by employing a heat exchanger integrated into a water storage tank. Deployment of the system would substantially reduce the energy consumption for heating/cooling of buildings as well as mains water supply and so reduces energy costs and emissions of C02.The UK industry for GSHPs is very small compared with the USA and other EU countries. One of the barriers to the wider use of GSHPs in the UK is the cost of drilling deep bore holes for the installation of ground heat exchanger loops. However, this barrier could be overcome by making use of a rainwater collection system that employs underground storage tanks. Collection of rainwater for use in buildings has been practised since ancient times. Concern over the environment and frequent water shortages have led to renewed interest in the collection of rainwater for use in buildings. Collection of rainwater reduces loading on water courses during rainfall and encourages conservative use of water, thus reducing the energy consumption for processing and long distance transporting mains water. Water stored in this way could be a suitable energy source for heat pumps. The dual use of grey water as a supplementary water supply and as a heat transfer medium would enhance the economic viability of GSHPs.
