    POTTERTON PROMAX 28 COMBI Boiler - Hot Water Issue

    Hello, I am seeking some advice, I have a POTTERTON PROMAX 28 COMBI Boiler and I noticed yesterday that the water around the house is no longer warming up. The heat exchanger has been changed 6 months ago, so I do not believe it is that. Does anyone have any ideas on what it could be? Thanks

    Potterton 28 odd behaviour?

    Hi All. As this is quite an old boiler ‐ I'm hoping there are many people familiar with this issue. The boiler works normally for hours (hot water and/or radiators). Then, it appears to be resetting itself every few seconds. This may only be a problem for radiators? Hot Water and radiator...

    Fully pumped CH systems? Potterton Profile 80e conventional boiler.

    AFAIK the boiler is set to fully pumped. (The switch inside is on fully pumped), however the pump is only running while the boiler burner is actually lit. My understanding is that a fully pumped system should have the pump running for a while after the burner goes off to circulate the heated...
