I very recently had a new boiler fitted by British Gas. It works OK, but I have concerns about the commissioning of the system. What happened is this:
When the fitter was working, I noticed he only drained down the upper floor of the system - the lower floor radiators were not drained. He just drained down enough to enable the wall mounted boiler to be replaced.
After he had departed, I found evidence that the inhibitor had been added, but there was no sign of any cleaner being used prior to this. I am very certain he did not use cleaner to flush the system prior to refilling and adding inhibitor.
They have offered to return and drain the system fully, refill and add new inhibitor. Should I accept this, or should I insist that they fully clean the system first, as the boiler is new and there are new solder joints?
Bear in mind that the system was already fairly clean as I flushed it and cleaned it earler this year. What's the realistic risk from just refilling without an extra clean?
Thanks for any advice
