Magnetic cleaner recommendations

[cdbe]

I'm fitting a few used radiators to my system and while they seem pretty clean I know there's going to be some rust inside simply because they've been sat empty for a while.

I'm looking for a decent magnetic cleaner that will be easy to fit to my horizontal return pipe, and if it exists, - that I can use to put cleaner/inhibitors in the system.

Thanks.

With your second hand rads, if not yet plumbed in, you could fill them with a citric acid solution, leave overnight, then flush well. Once installed, add inhibitor and you'll be good to go.
As you are probably aware, a magnetic filter needs to go on the return to the boiler, after the rads. It's to protect the boiler from crud, not the rads themselves.

Fernox Omega, Magnaclean and Spirotech MB3 all get positive feedback on this forum. Any filter is better than no filter, probably best to ask your boiler service guy which type he prefers (although you can empty the filter yourself)

Flush them through from both sides with a hose . Half fill them and give them a good shake with someone on the other end and hose through again. The plumcentre centre brand filter is a good solid brass filter at 70 quid

Please make sure you have taken into consideration how those rads will heat the space they are in. Those types of designed column rad cannot be gauged on output alone, as an indication as to how effective they will be at heating the space.
