    Hey all,

    Looks like we need to get our system flushed as we have a couple cold spots and areas on our radiators.

    I'm getting quoted 450 for 6 Radiators - 2 bed Flat.

    That's including VAT.

    Now this company does come highly recommended, has been around for quite a bit and guarantees that the system will be clear for 5 years.

    From plumbers and others who know about these things, does this sound good to you?

    From doing research online it seems perhaps slightly on the high side (50-100 more than some would expect).

    BUT - A big concern of mine is that this isn't just a company that half arses this, I want something that will last.
    Reason for that is that the last time this system was flushed was 2010 and it's already showing these signs. (previous owner).

    Some of the cheaper quotes you've seen might be as part of a new boiler install?

    Oh really?

    So you feel that for the size of my place 450 is okay?

    No, I'm horrified at that price :( Just trying to think of a reason why prices differ so much.

    How old is the boiler, how many rads are affected?

    As with all of these things, if you don't like the price then simply do it yourself.

    As in take the radiators off or hire a power flushing machine? I've got a dead radiator and I'm probably just going to take it off the wall and give it a damn good thrashing Basil Fawlty style.

    I've taken a couple of radiators off in my old house before. Took them outside and bodged a hose in them with the rad upside down and waited until the water ran clear. Takes a while but did the job.

    I've just been quoted a power flush at £360 + Vat for the same house which I now rent out as the bathroom rad was cold even though it was bled. I got someone else to go and look and they replaced the valve for £70 and that did the trick.

    I have also texted my plumber today about 4 of my downstairs rads as they are hot at top and cold/warm at the bottom. He has said they may need balancing but is coming tomorrow and if not I will ask him how much to powerflush.

    Take them off and get the hosepipe on them and then whack them with a rubber mallet.

    Personally I'd hire a powerflush machine and then use the chemicals but I am able to do it. If you can't then you have to cough up and pay someone.

    Remember, it's not just the cost of doing the job, that's probably only worth £300 but the rest of the cost is knowing how to do the job.

    Was it a TRV valve? I had the same problem with a rad and my guy told me to unscrew the TRV valve which exposed a small basic pin underneath. Small pair of pliers gripping it then up down up down up down with the pin which freed it up, back on with the valve head et voila. In my case it was simply that the pin had set in its lowest position and wouldn't rise

    No, it was a valve on a chromed towel radiator.

    Does it have to be a powerflush, or simply a full drain down and refill? If it's the latter then it's fairly easy to do yourself if you have the time / inclination. You just need a decent length of hose pipe and a bottle of the chems from B&Q or Screwfix. I did this at my last house, worked a treat. I avoided a powerflush as this can cause problems with old radiators.

    My neighbours heating packed up a few weeks, they called out a plumber and he got it working of sorts, charged £180 for this and then explained that they needed a power flush and gave them the quote to do this....Ready ? ..................£1100+VAT :eek:
    I nearly spat my drink out when they told me, not a big house at all and would all be done in a day.
    I urged her to get other quotes but she don't do that sort of thing and promptly whipped out her cheque book.
    The prices above in the thread don't sound that bad to me but this was just taking the P :thumbsdow

    I charge between £150-£800 for a power-flush, depends on the type of system, combi's are easier than open vented for instance, 15mm-35mm easier than micro-bore, copper better than plastic. Old rads have more potential problems than new rads, sole trader will be cheaper than a larger company, man with a signed up new van will be more expensive than a chap with a banger..
    Guy with a Kamco machine will charge more than the bloke with a hose pipe and some BQ chems etc, etc..
    Distance to job, access, parking, site issues such as access to bolier, rad or pump, access to drain and mains all affect the price.
    There are plenty of trades, if you don't think the price given represents good value, either find another who does or do it yourself.

    I think a few people here think that I think the price is too high.

    I don't think it's too high/a rip off, I'm just trying to do my due diligence to ensure it's a fair price (as I have no idea!)

    Thanks all for the feed back. - sounds like I'm on the right track.

    @neilios Yes these people seem to have all the proper stuff - Kamco Machine, PH levels before and after, 5 year guarantee on their work etc etc.

    Hi my Mum had to get one of these done and sorry to say, she paid between 600 and 700 quid. That was Scottish Gas, property is coming up for 20 years old (1997) so as such so is the boiler.

    That does sound quite high - unless she has a big house?

    No infact she only has a small 2 bedroom house up and downstairs, but i think the issue was the house builder failed to put the solution into the system to prevent rusting so as such there was mountains of crap inside the pipes which had to come out

    This thread resurection reminded my to clean out my Magna Filter.
    A while ago i got a new boiler with a flush and afterwards, i had a couple of old radiators with cold spots. I just replaced them with new ones, since i was taking them off anyway, and less hastle than cleaning them out and "maybe" would work after that.

    I was going to clean out the filter before winter hits and this thread has reminded me to do that!

    Apologies if this is a stupid question ;)

    People are speaking of power flushing and cold spots or dead rads.
    Ok, let's put dead rad to one side as that's a bit obvious.

    But what exactly would you describe as a cold spot which would be cured by power washing?

    If you have older rads, which are thicker steel, as I understand it, they will take longer to fully heat up to "OMG if I touch it, it hurts" temperature.
    Heat / hot water rises so the top of the rads will get warmer than the bottom, likewise I guess the middle of the bottom will be the last to get up to temp?

    How long for the whole rad to get all up to the same temp, with a old thick steel rad would be considered normal?
    Probably hard to answer as depends on the size of the rad, and one of mine is about 2.5m long!

    I guess I'm just trying to get an idea of what is just normal, and expected, as these things all take a while to fully get up to temp, and what would genuinely be considered a cold spot, which would be fixed by flushing.
