Hi all,
Recently moved into a house with a newish boiler - ideal classic HE. Unfortunately the pipework is all 8mm microbore.
So I've power flushed the system and refilled with mainly distilled (hard water area) and fernox.
Other than regular rad bleeding - as with all drained and flushed jobs, the system has been good.
However, two months in and with the cold weather I find the boiler regularly trips out on high temp. I suspect the pump (Grundfos) is not providing the required throughput or maybe the boiler is airlocked or coked?
Any advice appreciated.
