Am putting in solar and battery system. I know I can heat my hot water with an immersion heater, but can I also fit an immersion heater into the closed central heating system that is currently heated by my oil-fired boiler?
I can't find anything online about immersions in the wet central heating system. Is it possible? common? where would I fit it?!
