That's my thoughts too @kidgreen61 but not something I want at this time of year ♂️
Any recommendation for a replacement that won't suffer the same fate?
I'm assuming there's nothing else out there with the same flue arrangements which was the main reason for using a Keston in the first place.
Am I missing something?
Just so you know, I'm an ex corgi registered fitter (long retired from it) never a heating engineer. I installed this system many years ago and really apart from this problem it works well. It's a Keston System 30 system boiler.
Ok, the system is losing at least half...
