As above really, not a chemical flush - a proper power flush. Any ideas? 4 bed house if thats any help...

They all seem to quote a couple of hundred quid.
This was 5 years ago when I was getting quotes to install a new boiler.
Seems over the top for what it actually involves.
Depends what guarantee you want after it's done really.
And the "chemicals" they'll try and sell you 😉
Had our system power flushed last year. Plumber was here all day (about 9 hours). 8 radiators flushed & a couple of new valves fitted. £500 all in. I know that sounds a lot, but it's the labour that costs.
Edit: Oh, and it made a massive difference to the CH. We had to turn it down a couple of levels immediately after flushing. Along with the double-glazing and government subsidised loft insulation we have installed, we're in for a toasty warm winter.
Cheers all. Plumber who fitted our new boiler last year supposedly flushed the system before doing it. Turns out he just poured some chemicals into the system when it needed something more than that and as a result has been amking the new boiler he fitted work overtime!
He quoted £400 to come and do it properly. Told him to **** right off. Couple of hundred quid sounds better. £500?! Jesus christ... I'll buy a bigger jumper.
a proper job takes all day..
you ll see a large pump about the size of a washing machine fitted into your central heating normally in the airing cupboard or by the boiler ech rad will be turned on and off and isolated in turn.
at the conclusion you should be able to drink the water inthe system..
the chemiclas do an important job more of which in a mo.
first consider why you need or think you need or are been told you need a flush..
is your pump or valve or even boiler been affected by ferrous matrial deposits or is you water full of sediment, what size as you pipework to the rads 10 15 22 or 28mm
the water may run clear when you vent the rad but losen a rad valve and it may be black or worse chocolaty
having been convinced that youd like it to be cleaned whats best there are two products central heating cleaner.. which is for new systems and is meant to clear flux and solder deposits and sludge remover which does what it says on the tin
once clear use inhibitor toprotect the insides of your rads and prevent corrosion
theres good bad and ugly two brands stand out fernox and sentinel they will cost approx £18 for each treatment
personally i'd go for a hot chemical flush for best results.. use a sludge remover in the system for up to a week then flush out . drain entire sytem and remove each rad and flush outside with hot water until clean.. be amazed how much muck comes out replace and use an inhibitor for a bells and whistles job add a magnatex or i prefer a fernox fp1 to clear any remaining deposits for ever for free..
dont sppend more than 300 BG will ask you for circa 460 some flushing companies pay plumbers finders fees for flushes so be warned.. and when finished ask what the PH reading is that ll sort out the men from the boys and ask for a certificate explaining the work carried out and the chemicals used and ask for the empty bottles..
dont sppend more than 300
That sounds about how much my mate does it for. With the chemical flush.
