Engineers at Glasgow University have designed a prototype heat pump claimed to deliver up to 10 per cent efficiency gains on current devices. The design couples a traditional air-source heat pump configuration with integrated heat storage in the form of a small water tank and a coil of copper tube. Excess thermal energy from the heat pump's operation is captured and stored in the tank, which is used at a later stage to boost efficiency, as the stored heat is warmer external air.
