Hi. Our central heating system has only three radiators, and has been installed for about seven or eight years. Yesterday, it was noticed that there was a bubble of paint/enamel (a bit bigger than a penny) at the bottom of the largest radiator. When this was pressed, brown muck came out from the bottom of the bubble (however, it is not dripping of its own accord — yet). It seems obvious that corrosion has been at work. I believe that it's possible to fix a small pin-hole such as this, with some kind of filler, but my guess is that if one hole has appeared, others are likely to follow. So, my reasoning is that it would be better, and save trouble in the future, if this radiator were replaced. The other two radiators show no sign whatsoever of any corrosion/leaking. However, since it would be necessary to power-flush the system before fitting a new radiator, I don't think it would be wise to risk later corrosion of the other two rads by leaving them alone, because if this did happen, another expensive power-flush would be required. To me, it seems sensible to replace all three rads, and have a single power flush, all at the same time.
Could a knowledgeable person comment on my reasoning, and tell me whether I am letting concern rule my thinking, unnecessarily? Is there any other course of action that would be cheaper, but also reliable? Because my wife and I are quite old, I would not want to run any risk of my wife being left (if I died first) with a dodgy central heating system.
Any helpful comments would be appreciated. Thanks!
