Hi. After many trips up and down stairs, I can't for the life of me work out what's heating my hot water. Have gas heating and hot water plus a backup immersion heater.
I have turned the spur off for what I believe is the immersion heater in the kitchen and to double check also turned off the switch in the airing cupboard which leads to the immersion itself. Leaving the spur on for the boiler but with the central heating and hot water turned off on the programmer, I am still somehow getting hot water.
I turned the boiler spur off and drained off all the hot water til it's only cold coming through. Turn on the spur under the boiler and I'm getting hot water again.
Anybody any idea how the water is still being heated
