Hi
I've read a lot of stuff incl lots of threads on this forum but not come across this idea so I'm assuming its probably not a good idea....
Anyway, seems to me the main benefit of powerflush over mains flush is that with powerflush the water stays hot and you can control how much chemicals and flushing takes place. With a mains flush you just get cold water at pressure.
So, my idea on my open vented system is to get the water hot and circulating using CH pump as normal then to open a downstairs drainoff with the water still circulating and boiler on (max temperature). I would ensure the flow on downstairs drain is less than the flow from the header tank so that overall no air gets into the system. I'd force water through individual rads as normal as I'm going it. Then finally would give each rad a mains flush.
A waste of time? Even dangerous? Or maybe a good idea?
As ever, grateful for people's thoughts.
