Hi to all, I have posted a question before on no hot water coming out of my potterton oil flowsure combi boiler. since then an engineer has taken the plate heat exchanger off and chemically cleaned it out. still no hot water, but the pipes going to the diverter valve are really hot. he did say that the main heat exchanger or the valve could be the problem. the system has been flushed out so many times I cant see it being the main exchanger.
Any help would be great and appreciated
