About power flushing

[sequence dancer]

I have been told I either need a power flush or a sulution put into my system left two weeks to let it desolve the gunk and then drain it and re-fill it or a full power flush.

my boiler is clogged up so the engineer as told me, a spring that lets the water go to the central heating cystem is not working, due to sludge,so the boiler is turning itself off after 1 minute, and stays off for about five minutes and then repeats the process.

can anyone advise me if the power flush at £500 or the sulution to desolve the gunk at £200 would work.

powerflush at £500 who quoted you that? thats very expensive.. how many rads do you have...
I spose if is definitely sludge is the cause then i would say go for the full power flush but not at 500 notes, look around i would expect to pay 200-300 and would take around half to a full day to do properly as stated by the large firms like kamco ...

So for all you powerflushing people i am after a new flushing machine, is there any reccommendations.
My obvious choice is the kamco, (and dont even say the ones that have the same motor as them as they are rubbish)
So what have you got, any good and reliable...
