DECC Heat Pump Trial:
A trial of ten home systems of air-source heat pumps with Sunamp heat batteries has been funded by DECC under the Advances Heat Storage SBRI competition.
Seven homes from Berwickshire Housing Association (mostly electric heated) and three staff homes were selected as part of the trial.
The goal was to shift 100% of heating to off-peak electricity using a heat pump. This would normally need the equivalent of 1500litres of hot water storage. Only Sunamp heat batteries are compact enough to make this practical in ordinary homes.
Initial results are showing significant savings to householders.
