Hospital to use ground-source heat pump
18th September 2024
UK: Global resource management company Veolia is set to combine ground-source heat pumps, thermal store, solar and CHP technologies to decarbonise the heat supply at the University Hospital of Hartlepool.
The system is designed to deliver carbon savings of 2,179 tonnes per year. It will make the University Hospital of Hartlepool one of the first hospitals in the country to use an aquifer-based ground-source heat pump system.
The new scheme combines a 1,400kW ground source heat pump system with a 70,000 litre thermal store to optimise the efficiency of the system by operating the heat pump at a higher load, when it is most efficient, to charge the store and deplete it over several hours.
To maximise efficiency and give N+1 redundancy the heat pump will use the supply from two boreholes and will be supported by 1MWp of renewable electricity supplied from ground and roof mounted solar PV arrays.
Veolia’s specialist energy team has developed a bespoke management solution which will manage the electrical and thermal balancing of the system and optimise the overall system efficiency using smart controls.
Energy efficiency will also be extended through the installation of LED light fittings and upgraded air handling units.
