We will use a Water Source Heat Pump to take heat from water and boost it to the required temperature.

We have contingency measures in place for particularly cold days, or if there’s some reason we can’t supply heat from the heat pumps (such as maintenance). Our Energy Centre will also have gas boilers that will automatically kick in so there is no loss of heat to connected buildings.

Currently, gas boilers are the most cost-effective way of providing this backup, but our intention is to move away from the use of gas as early as feasible.

We’re investigating other opportunities for heat generation. We have committed to the Exeter Energy Network being Net Zero by 2030, so we’re also considering other sources of heat such as geothermal, renewable gas, hydrogen and electro-boilers.
