They make a fortune from power flushing.
they dont actually.
The annual service charge whilst expensive is actually a pretty good deal if you have a system that requires constant attention so in order to even things up they push or 'advise' you get a PF done for about £600 but most 'normal' houses could replace all of the rads for that price.
what?? 10 rads plus labour plus chemical plus a lifetime guarantee to to replace those rads again if they go all black again?, you must be losing money hand over fist man.
Why would you spend £600 on old stuff when you can get new stuff for the same money?
see above, in "most cases" you cant.
Never made sense to me however they make it a condition of your contract once they get a 'sniff' of sludge that your contract is limited if you don't have a PF done.
this clearly makes you out to be a poor businessman. something almost entirely out of their control is not covered by the contract, but this makes no sense to you.
Believe they will change a rad once and 'advise' re PF and if you decline then the other rads in they system are no longer covered on the contract
you got something right at least. they will change as many rads as you need, provided the water that comes out of the rads is not in some way contributing to the demise of said rads. not only that but any water part that is subsequently damaged due to that water is also not covered. harsh isnt it
****** you can buy 1400X600 DP rads with tops and sides for £45.
Even allowing for ten of those and etc your talking £500 tops ex fitting.
I know what I would rather have.
Power flushing is but a con mate.
£800 for the machine plus chemicals means you have to push it to people who don't need it.
Customers gain no real benefit from it.
I've been changing boilers for over 18 years and I never do PF and have had very little problems.
Once I did a PF for a mate after the gas board said he needed it done but guess what? The pump was phucked!
I change the rads if they really are that bad and that has only happened once or twice.
I've drained thirty year old systems and you could have used the water to make your tea however systems of that age and older were normally installed properly.
And,BTW I'm a tradesman not a business man but I have managed to remain self-employed for nearly 20 years so I must be doing something right.
