I have a Potterton combi boiler and about three years ago I noticed that the central heating was activated when the water only was activated i.e. the radiators would heat up. About 2.7 years ago the diverter valve was replaced in my Potterton Boiler by a local plumbing company (see linked question). I advised the company shortly after that there was an improvement i.e. the radiators were not pipeing hot - just slightly warm. At the time I was informed that it was normal for this to happen to prevent overheating when the water was on i.e. heat would escape through the central heating. However, this has got gradually worse.
I had the boiler serviced in July by the same comapny and again I was advised that it was normal for the radiators to warm up if the heat needed to escape i.e. to prevent overheating. However, today anther plumber from the same company (the owner in fact) arrived and negated this statement. He has advised me to replace the diverter valve again. He has said that a diverter valve could last six months or could last ten years. I have a few questions:
1) Should the boiler service at the end of July have identified this as an issue? I did mention is at the service, however the servicer said it was normal to prevent overheating.
2) Should the diverter valve last more than 2.7 years?
I am happy to pay for another diverter valve to be fitted if necessary. However, likewise I don't want to be taken advantage of. Hence the question. Should I take issue at any of this or just suck it up?
