The Castle Park Water Source Heat Pump (WSHP) project in Bristol has been named as the winner of the “Heat Pump City of the Year” award at the 2022 European Heat Pump Association awards held in Brussels earlier this week.
The awards attracted almost 50 of Europe’s highest profile WSHP projects and saw the Castle Park energy centre claim the top spot, shining a spotlight on Bristol’s low-carbon heat network.
Scott Lutton, Vital Energi’s Operations Director – North & Scotland, “We’d like to congratulate Bristol City Council and Goram Homes for their fantastic achievement. This project demonstrates that WSHPs can plug into existing networks and opens up the possibility of harnessing the Gigawatts of ambient heat in the UK’s rivers, which will play a large part in meeting our net zero targets.
“Heat pumps can lower energy bills and deliver strong carbon savings and Castle Park is one of the first major WSHP projects in the UK, so we’re delighted that it has gained recognition at the European level and hope it will inspire other similar projects going forwards.”

The Castle Park energy centre takes water from the nearby floating harbour, passes it through a heat pump and then the heat is transferred into the Bristol Heat Network, helping to lower the carbon emissions of approximately 1,000 homes and businesses.
The European Heat Pump Association was created in 2011 to collect best practice, create role models and raise awareness of the potential of heat pumps and the awards are one of the keyways the association shine a light on the industry.
