Thank you ?
In a way I do all 3, chemicals in after the initial blast around the system with just water in the power flusher then if possible fire the boiler and add a bit of heat. Agitate the rads with a rubber hammer. Then it’s a clean water flush out. All this is done with a big magnet in the system.
mag cleaner picking up the magnetite out of the system.
If the systems has sludge in already a magnaclean type device won’t be up to the job as the sludge will have settled in places the circulating pump in your system won’t shift. well worth putting in a new or cleaned system though.
Thank you, that's handy. I'm concerned a chemical flush alone may be insufficient. From research it seems a powerflush involves higher volume (but not pressure) water approx 10x the flow to keep bits in suspension. Better to do a job once and get it right than do it twice. It's not a cheap job from the quotes I've had - works out about £700-800 on a 10 rad system. Your comment about 9hrs to do a 12 rad system shows how labour intensive a job it is and that adds up.
