Someone please put me off...

Am considering building my own powerflusher machine using a load of lever valves and an old Grundfoss 10-60 circulator. They seem to coat £300 second hand otherwise.....

Is this wise??

 

[swbjackson]

Have you got a mop and bucket or preferably a wet vac. You'll need one if you try to cobble your own machine together.

 

[gaswizzard]

You need a 'pump' not a 'circulator' , BIG difference.

 

[Boilerman2]

Are you for real??? DO NOT DO IT
you would need a Grunfos CP4 Pump at least to provide the head pressure required for power flushing, these cost more as a component than a Kamco CP90!!

 

[Axel]

Ok then, it's just a 'flusher' that circulates chemicals around rads at the same rate as a boiler, with option to reverse flow and dump.

Don't need one mate.

Mains cold water, hose pipe, two drain cocks.
Cheap as chips. Powerflushing is grossly overrated.

DC, are punters gonna pay £700 for BG to do that?, or me a 'mere' £400. They expect to see summat a bit, well, hiTech-ish. With a bit of mumbo-jumbo, some clanking around in the roof space for a coupla hours. Numerous visits to 'check flow direction/chemical concentration levels etc'

Bingo, Bongo, Bango - job done, roberts your mothers brother - and out comes the invoice book.

You trying to bite the hand that feeds you?

It is overrated, but with your suggestion the water simply passes through the open paths of the system without collecting any sludge. All it shifts is what's already suspended in the water. Only chemical breakdown or physical shaking will disturb the stubborn stuff.

Op you've gotta do it, especially if you're going to sign the ticket that a powerflush has been done as part of one of your installs.

The boys on here laughed at me, and yet I have a small rad in a cupboard with a shedload of neodymium magnets on it which I take off and flush through a couple of times a year (got a couple of inline full bores to help this). Dries my towels and better than a magnaclean at a fraction of the price.

I can laugh at that too!

Putting a magnet on the OUTSIDE of a steel rad will mean that virtually all the magnetic flux will pass along the radiator steel and not go through it as you hoped !

Unless you close the boiler valves and intercept the boiler flow pipe to drain (assuming the filling loop is on the return) and close all but one rad one by one.

Scoff you may, but it works extremely well. Back to school for you Tony

 

[Nige F]

those magnets must be real powerful Have you ever put them near your `leccy meter

No need to - I bypass the meter anyway
