Thanks Ian. Don't have an airing cupboard. When I click the switch on the box on the wall to hot water and turn on the electric, there are loads of little flames that come behind the fire. Usually they stay on a few minutes then go off and come on again all the time til I turn off the electric...
Hi I wonder if anyone can advise. I have an old fashioned back boiler and when I turn it on the fires that heat up the water stay on constantly. I have to keep switching it off by the electric for 5 mins then back on again, to get some hot water in the tank. Any help please ?.
