At the end of last year, the Heating Swaffham Prior project engineers made a very exciting change to the project design. Originally, the back-up boiler in the proposed village energy centre was planned to run off gas, in response to community feedback, this has been replace with an electrode boiler.
The electrode boiler will provide village-wide, back-up heating during the coldest winter days, or when the ground source and air source heat pumps undergo maintenance.
This means that the project can now rely 100% on renewable energy, a green electricity tariff or electricity from local solar PV will be used to run the boiler. The electrode boiler will also improve the overall commercial and energy efficiency of the project, as the system will be able to optimise energy production between the air source, electrode boiler and ground source during winter.
