Power flushing system with mixed pipe sizes

    As mentioned in a previous thread my radiators are not getting hot enough - they are warm but not hot although they seem warm overall,not just at the top. It was suggested that a power flush of the system might be needed but 3 of the radiators are connected to the 15mm loop by 8mm pipe ( don't ask why, they were like this when we moved in) and I read somewhere that power flushes don't work with 8mm pipe.
    Is it worth the cost of flushing or is it worth trying a descaler such as X400?

    <<<<<<power flushes don't work with 8mm pipe.>>>>>> I'll go further than that and say, powerflushed don't work on any size of pipe, they are a circus act, invented by out of work zeppelin designers when the world no longer believed their stories of air travel they found another way to convince people of their worth, " lets clean stuff from the inside, that way nobody can see if it works or not" was the opening speech from the first ever meeting they had,
    and the rest is history, :rolleyes:

    If they are done correctly, they can make a big difference to a heating system, especially now we have portable thermal imaging cameras to show customer before and after.
    Get back with them Dinosaurs Tom :(

    Bet you didn't move with the times when they brought out PTFE instead of boss white and hemp. But I bet you did. Prob still using junior hacksaw instead of pipelice. Sooner use powerflush than taking radiators off the wall and trail black sludge over Lounge carpet.;)

    catchup, my arguement about buying gadgets is YOU have to charge more to the customer to claw back the cost, nobody gives you a powerflush or a thermal camera or a fga, therefore you have to charge more to pay the maker of gadgets who's convinced you that, " your actually doing the customer a better service with these groundbreaking tools" instead of the truthfull " you're lining my pockets, here. why not buy a tie with powerflush king on ":)

    Well her indoors was not having WORK DONE over the xmas period.
    The Intergas rep was calling last week on his way south from Scotland but never appeared.
    I just wanted to see one in the flesh as it was as he carries one in the boot of his car Lol.
    Its all stripped in one of the local sales places so you can see what is NOT in it.
    I am just concerned about it being a bit of a "rare bird"
    The old Potterton has worked for 36 years so why not a few more weeks.
    Lots of BS advertising around on boilers to.

    But I will get Santa over first.

    In passing the comments on Boss White.
    My overalls were stiff enough to stand up on there own with always
    wiping my fingers on them lol.

    Have a nice Xmas.
    This is quite a nice place to look around .

    Merry Xmas all you guys.

    Hi JM, refreshing to hear someone who knows that adverts are there to con people and not to help at all, but don't worry about Itergas, they ave a good reputation thou I've never fitted one, you smell like a good plumber, wemen love that combination of boss white cutting oil and plumbers sweat , if any of the leading perfume makers think of bottling it, they'll make a fortune, well anyrode nice chatting see you around, gotta go an earn a crust,;)

    Hi, this discussion seems to have evolved some way from my original question. There seems to be a consensus that power flushes do work - does this include a system with some 8mm pipe? Which raises the question of why is 8mm pipe fitted into a 15mm circuit in the first place.

    Do not pay for a power flush on 8 mm pipe, it just wont work. A powerflush works by flow throughout a system 8mm pipe is too small.

    Thanks for that Dave, that's saved a few bob. What was the point of mixing pipe sizes in the fist place as they are only short lengths of 8mm t'eed from 15mm pipe?
