A nursery school in Cardiff is currently being heated from warm groundwater pumped from under the building. ‌​‌​‌​​​‍‌​‌​​‌‌‌‍‌​‌‌​​‌​‍‌​‌‌‌​‌‌‍‌​‌‌‌‌​​

Grangetown Nursery School on Avondale Road uses a pump and heat exchanger to remove heat from the reservoir of water in the sand and gravel under the city. This is achievable as the groundwater under Cardiff is often at only 3-4 metres below the surface and is warm at around 14 oC due to the heat lost from buildings, sewers and other underground infrastructure. ‌​‌​‌​​​‍‌​‌​​‌‌‌‍‌​‌‌​​‌​‍‌​‌‌‌​‌‌‍‌​‌‌‌‌​​

Cabinet Member for Transport, Planning and Sustainability, Cllr Ramesh Patel said: “I am delighted that Grangetown Nursery School is keeping the children warm this winter thanks to such an innovative and environmentally friendly system. I am extremely proud of our Green Energy projects across the city. Schemes such as this underground heat capture system and our hydroelectric development at Radyr Weir ensure that the council is in the vanguard of the UK battle against reliance on conventional fossil fuels.” ‌​‌​‌​​​‍‌​‌​​‌‌‌‍‌​‌‌​​‌​‍‌​‌‌‌​‌‌‍‌​‌‌‌‌​​

The system was installed as the result of a local partnership between City of Cardiff Council, the British Geological Survey, Cardiff Harbour Authority and WDS Green Energy Ltd. Last year the project received funding from Energy Catalyst Innovate UK. ‌​‌​‌​​​‍‌​‌​​‌‌‌‍‌​‌‌​​‌​‍‌​‌‌‌​‌‌‍‌​‌‌‌‌​​

The Head teacher of Grangetown Nursery School, Jan Comrie said: “We certainly haven’t lost heat as a result of adopting the heat pump system. In fact it’s quite the opposite as the school is so cosy. We were delighted to take part in this project as it builds on the work we’ve already done as a school. We’re the only nursery school in Wales to have received a Platinum Award from Eco-Schools Wales. Our attitude is that if organisations don’t try new eco-technologies we’ll never know if they work or not. Therefore we signed up for the scheme because as a school it’s important to us that we contribute to the development of these technologies.” ‌​‌​‌​​​‍‌​‌​​‌‌‌‍‌​‌‌​​‌​‍‌​‌‌‌​‌‌‍‌​‌‌‌‌​​

City of Cardiff Council is taking the lead in renewable energy technologies to reduce carbon emissions, improve energy security for the city and reduce energy costs. The project is looking to test whether the reservoir of water in the sand and gravels under the city could be used as a renewable and low carbon resource for a district, or even city wide heat network in the future and will therefore be closely monitoring the carbon saving that the project can deliver. ‌​‌​‌​​​‍‌​‌​​‌‌‌‍‌​‌‌​​‌​‍‌​‌‌‌​‌‌‍‌​‌‌‌‌​​

The Natural Environment Research Council (NERC) is the UK’s main agency for funding and managing world-class research, training and knowledge exchange in the environmental sciences. It coordinates some of the world’s most exciting research projects, tackling major issues such as climate change, food security, environmental influences on human health, the genetic make-up of life on earth, and much more. NERC receives around £300 million a year from the government’s science budget, which it uses to fund research and training in universities and its own research centres. www.nerc.ac.uk ‌​‌​‌​​​‍‌​‌​​‌‌‌‍‌​‌‌​​‌​‍‌​‌‌‌​‌‌‍‌​‌‌‌‌​​
