I am thinking about installing a magnaclean into my system. had BG out a few months ago and they put a magnet onto my pipework in the airing cupboard which stuck to it! i have since run a couple of flushes through the CH system and drained down several times and added inhibitor. question i have is which pipe is best to install the magnaclean on? i probably need a powerflush but thought this might help in the interim?

Did you use any chemical cleansing agent?
The return pipe between the last rad and the boiler.
Sadly, this is usually impractical, so the Magnaclean often ends up on the flow, between boiler and pump. Better there than nowhere.

Thankfully someone giving out proper advice about these things. In an ideal world yes they should go on the return by the boiler, but I've fitted quite a few of these things & in reality they go wherever you can fit them. As Softus says better there than nowhere.

If it's got deposits hard enough to stick a magnet to, normal chems won't shift them, you have to cut pipe out. Often it's only near the pump and quite accessible to small drain springs though. See the "pumping over" FAQ for a pic.
Print this out. Stick it on the wall, and throw a dart at it. Your task is to hit a white part. It's there if you look hard.
Me? Oh I'm in the grey area.
Ah well, experts, hmm....

how do you get to the FAQ's, i can't seem to see them. yes it was on the pipes near to the pump where they stuck a magnet. there isn't any blockages though. i presume when you say normal chemicals you refer to chemicals used with a powerflush? thanks for the picture, will sharpen my darts up!
To the OP
What problems do you have that gave the engineer reason to recommend a powerflush?
Have to get me one of those magnets that tell you if someone needs a powerflush. Beats checking radiators and checking water quality

problem was that some of the radiators did not get very hot, especially at the bottoom, we have taken some off and flush them through and this has improved things a bit. we put a couple of new towel rails on recently and they get alot hotter than the existing radiators.

it doesnt stop uou doing those neccessary checks, but its a very simple way of demonstration the prob to customers and pointing you in the right direction.
It doesn't tell you anything, other than the presence of magnetic debris, but not how much or how bad.
A bit of hardened sludge around the cold feed doesn't tell you you need a powerflush. BG engineers are pushed to sell, upgrades, cods, boilers etc.
they also get commission albeit a small amount(about £8 for a powerflush), but for a good seller it adds up nicely.
I'm not saying the guy doesn't definately need a powerflush, but I've gone to many jobs after engineers have recommended powerflushes only to find duff pumps, badly balanced systems, blocked cold feeds, duff rad valves, even empty header tanks!
All these things should be investigated first before recommending powerflushing. Even if you have a blocked or partially blocked c'feed a bit of routine maintenance after can be sufficient to prevent re-occurence.
