Hello.
I have a vizo 24 boiler. About a year ago the hot water would run but the boiler kept clicking on and off. I replaced the dhw thermister by the diverter valve as a long shot and it solved it.
But now its started doing it again. I've replaced the thermister again but this time it hasnt worked. If the temp knob is turned up on max it just heats up water for a short while then clicks off though if its turned lowish and the water is run slowly it will keep going.

I'm looking for a heating engineer that knows there way around a vizo boiler to repair it now. Is anyone in or Nr portishead?

Thanks guys.

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

Hi all. Hope you have all been keeping well. A while back I decided I only wanted to fit one brand of boiler and decided on Viessmann due to space for servicing and changing parts if ever needing to. I am finding my decision rather hard due to the different clearances on flue runs and cupboards...
