    Bleeding rads on open vented system

    On a thread I started recently , cannot find which one, somebody mentioned that bleeding of the rads on an open vented system should be done with the pump off so as to not possibly draw air into the system. Do I read into this then that auto bleed valves are not a good idea on that type of...

    Very loud noise of rushing water in rads.

    We recently moved to a rented property. Last Spring it was converted from oil to gas central heating. The property is a 1960'S chalet bungalow. The current boiler is made by Ideal and was new last Spring. The heating works and heats the house very well, but the noise is unbearable. The bedroom...

    Evenin' I drained, removed and then replaced 2 large rads upstairs to decorate. And now they're only getting warm, and in patches, not evenly. The bottoms are almost cold, and some upper areas are actually quite hot. It's a conventional boiler, gravity fed system. I didn't touch anything in...

    Measuring rads W x H or H x W

    Ok, so if your in the Gas Safe forum you can view my worst week ever. One of the jobs that went wrong in that week was a basic rad single panel for double swap, should have been nice and easy, plenty of movement on the 10mm pipe. Only it went wrong because I turned up with a 600w by 400h rad...

    Hot flow and return pipes, hot upstairs rad but cold rads downstairs

    As in the title, the flow and return pipes both get hot when the heating is turned on, yet only the upstairs radiators get hot. I am very puzzled by this. Even turning off all thermostatic valves upstairs, none of the downstairs rads get hot. Our plumber says there must be a blockage looking...

    Cast Iron style rads on 10mm

    Hi, A customer wants cast iron style rads throughout, 9 or 10 in total but currently has 10mm pipe . Is there any problems installing this type of rad on mircobore? I'm worried about the water content being much higher and it not circulating? Anyone else installed these on mircobore? Cheers
