Hi, I have a fuelsaver 100f boiler (old and inefficient, I know!) on 15 rads but recently some of them have started just getting lukewarm. All rads are bled and the TRV's have been checked with no probs. The supply pipe to the TRV is very hot but the rads are not hot - I thought the TRV would be at fault but the valve pin seems to be moving freely. A gasfitter today looked and advised all looks ok so he'd advise a powerflush for £600. The system was powerflushed 5 yrs ago so is this unusual to need another flush so soon after the previous one?
Please advise as I don't want to think i'm being ripped off. Thanks!!
