Heating coming on when running bath? (vokera excell boiler)?
My Heating is turned off at the boiler but for some strange reason everytime I run my bath (hot water) the radiators come on and then go off when I turn the tap off. Does anyone have any ideas why?
divertor valve sticking in central heating position. it should move over to block ch and allow hot water transfer when tap is opened but they stick or get cr*p in them which stops them moving over fully and allows some heat through rads.
Mr I've not got a clue either but hazzard an educated guess :-)
