Our Potterton Performa 28 is playing up - when running the hot water the radiators are warming up even though the heating is not on.
The hot water is not getting very warm -
particularly upstairs (boiler is located downstairs)
I'm thinking it's either the diverter valve or the heat exchanger - any help/advice would be appreciated
