  • Is your boiler down low or up high?

    Out boiler is in the loft and the return, uphill, side of the house has cold radiators. I am told it is due to gunk collecting at the bottom of the loop and robbing heat from the water.

    I need to install a filter apparently, but that means ripping out the carpentry in my cellar.

  • Is in kitchen, ground floor.
    Only have 2 floors.

    I think it's something to do with having two massive rads in the back room (living room).
    I think the flow goes boiler, split, upstairs front, downstairs hall, upstairs back rooms, downstairs.
    but fuck knows. I'm not a plumber.

  • Which is the hottest rad ;)

  • Balancing it is apparently a piece of piss. Turn the heating off and wait for the radiators to cool down. Then switch the heating on and check if any of them get extremely hot very quickly (probably the ones nearest the boiler, downstairs). If they do, shut the valve off on that radiator (not the thermostatic valve, the one on the other end) and then open it again by a half a turn. It should then heat up slower than the others but eventually reach the same temperature. Do that until all the radiators heat up.

    That's the "DIY-person-who-knows-nearly-nothing-about-plumbing" technique anyway, I believe.
