Potterton Perfoma 24. Hot water works fine No heating?
I have a Potteron Perfoma 24 boiler. The heating has stopped working Hot water is working fine. I've tried resetting the boiler and that doesn't work. The "Burner On" light comes on when we turn on the hot water taps but it doesn't come on and it switches off immediately once we close the taps. Pressure is just below 2
