Hi guys, had a new boiler fitted 3 weeks ago, the engineer (who is platinum 5 with Intergas) flushed the system and cleared a block in the feed pipe into the system,
Boiler is a Intergas Open vent 18 KW
He wasn't happy so put some more cleaning fluid (Not sure which brand) to circulate for 4 weeks and is coming back to drain down and refill and add fernox
System worked fine for a week or so, but we are now getting a noise when the pump switches off (Central heating side only)
Went up into the loft and there is a bubble coming up from the Feed pipe in the F&E tank when the noise happens, there is nothing coming out of the vent pipe, but the vent pipe does get hot when the heating is on (Expanding water?)
It doesn't do it every time, and only after the heating is hot and been running at least 30 mins and is worse the higher the pump speed
could this be a big problem, or could it just be the system cleaning etc with the cleaing fluid running round?
