Hi
I'm installing a new radiator in the bathroom connected to the central heating system. I intend to have an electric element for occasional use in summer.
I want to use the separate supply to the immersion heater in the hot water tank to supply the element. I have never used the immersion heater - the water is normally heated from a gas-fired boiler - but I want to keep the capability.
I know it would be wrong to extend the heater circuit. My question is: is there a household changeover switch so that they can't both be on at the same time and is that legitimate
