EDITORIAL Water opportunity E Alex Smith, editor Email: asmith@cibsejournal.com Twitter: @alexsmith68 d Davey has been a supporter of heat pump technology ever since a developer contacted him about using the River Thames to heat a new housing and hotel development at Kingston Heights, south-west London. The Secretary of State for Energy and Climate Change understood the benefit of boosting low grade heat using heat exchangers and heat pumps. Since then, his department has launched a water source heat map, which details 4,000 rivers, estuaries, canals and coastal sites that could produce 6GW of low carbon heat. One project looking at using the technology is Battersea Power Station, where SSE is doing a full feasibility study. In anticipation of a large uptake of interest, CIBSE has joined the Heat Pump Association and Ground Source Heat Pump Association to produce a code of practice for the UK. Supported by the Department of Energy and Climate Change, the code will be out this summer and aims to raise standards in the design, implementation and operation of water source heat pumps. Manufacturers are gearing up for a rise in demand for all types of heat pumps with more training on design installation, and operation. The roll-out has to be right first time or Daveys efforts on water divining will be seriously compromised.
