Hi.
Anybody comment on the need or otherwise to "de-sludge" a heating
system. Reading around it seems it's a recommendation every ten years,
but also just read somewhere that a properly installed system should
never need flushing.
Thoughts?

I have just had a filter installed, called a magnaclean this picks up
iron oxide particles which is the sludge that develops in radiators,
you can clean the filter and I was suprised how much of this sludge
the filter picked up. The heating engineer had nothing but praise for
the filter even though he admitted it would cut down on his work if
all systems had them.
