Yep..on the return.

Tony He seems less concerned with the sludge that is in the main central heating system as he seems to suggest this is already being dealt with by the Magnaclean - ie it is no longer getting past the filter and into the boiler so it is not causing a problem. He is concentrating on removing...

Hi JohnD - Thanks very much for your advice. The Magnaclean has been emptied recently as, coincidentally, the boiler was due for a service (ie have a service/call out contract but sadly the one thing that is not covered is sludge in the system :-( ) but I will do as you suggest and check it...

Thanks for your replies so far. bazdaman - the system was flushed 3 years ago when the boiler was installed and I've had no problems at all until the new radiator was fitted 6 months ago - the engineer says flushing can never totally clean magnetite from rads and pipes and moving pipes etc...

Oh. It hasn't been cleaned with chemicals or acids and I think the pipes are 15mm

Hi JohnD It's a MagnaClean filter. The sludge is black and hard and there seems to be a lot of it inside the heat exchanger itself each time the engineer comes. He,says it is working its way round insidecthe boiler and then getting trapped in the heat exchanger but that no new sludge is...

Hi 6 months ago I had my bathroom completely redone and this included fitting a new radiator in a new position. Immediately I started having problems - baxi combi boiler (3yrs old) reporting overheat error and shutting down hot water. Engineer eventually tracked problem down to magnetite in...

Thanks John and Pete. I tried scraping the grout with the point of a Stanley knife but din't get very far. Any tips on how to attack it? I'm not really used to diy etc. Mandy

Thanks John. It's complicated by the fact it's a tall vertical "designer" radiator and I can't see the brackets. It's not a towel rail type...panel. Do you think the grout is unlikely to be causing the problem?

Hi. My bathroom fitter has filled the holes in the floor tiles where the rad pipes come up with tile grout. The radiator creaks and clicks loudly when it's heating up. Might this be because the grout is preventing the pipes from expanding? If so, how do I remove the grout now and what do I...
