Hi I have a Potterton Performa 28i
The problem started with the hot water intermittently running warm instead of hot. The water would heat up when taps not on and then once taps run it would run only warm even though the burner was lit. After turning the taps off the water would heat up again.
The heating has now started to only run warm and not hot even though the burner is lit and never goes above the first three red lights lit.
Could this be the diverter valve stuck half way?
Any help would be appreciated thanks
