A surface water heat pump at Robinson College transfers heat from Bin Brook to heat the college in winter and provide hot water all year round. Heat pumps and seasonal thermal energy storage with a sophisticated energy management system provides a totally automated system that balances the temperature in the building by heat exchange with the water in the brook that runs through the college gardens.

The water source heat pump has been added to the plantroom and provides the baseload heating to the college. The previous gas boilers have been retained to provide resilience.
