Just under half (45-47%) of total final energy consumption in the UK is currently used for heating purposes with approximately 80% derived from fossil fuels. Of the total national heat demand, space and water heating account for 63% and 14%, respectively.

Where does electricity come from in a district heat storage system?

Electricity supply can come from CHP, if the district heat storage has spare capacity, or from a generic gas power station. A node’s energy network capacities are determined by three components: the peak energy flows, and the power and energy capacities of the stores and generators.
