Power flush question

[Taliz]

I am on a strict budget and getting a new system boiler.
I have bought a Magnaclean twintech and my heating engineer sugested not having a powerflush to keep costs down. He said if I turn off every radiator except one and take it in turns to go through every radiator in the system like this ,it will force most the gunk in the system into the Magnaclean filter.
For me the logic is sound as long as the Magnaclean lives up to it's reputation.
How good are these devices? Is the Magnaclean likely to let any gunk through into the boiler?

Why bother having half a job done, if something goes wrong in 6 months time your installer will say, "you didn't want it power flushed, sorry it's not covered"

Did you get 3 quotes? and much were they?

You will still have sludge lying in the rads. It needs power flushing.
