I inherited the above in our 'new' house and I've cleaned it maybe six or seven times in five months - excessive, but I don't think it was done before. So the first time it had a lot of muck, second time less, then I had a couple of new rads installed, so was cleaning it in case there was any cr*p in the system and so on. Anyway... Whenever it's cleaned the heating performs better (hotter). I can even turn down the boiler a few degrees. Any ideas why? The last time there were some miniscule rings of muck which I cleaned but nothing much. Is the flow that sensitive?
