    Determining the last radiator in the downstairs radiator run

    I am attempting to find out which one is the last radiator by using a DMM connected to a themocouple. All the valves are completely open.

    Radiator flex pipes

    Could I pull these flex pipes up by cable tying them onto the back of the radiator (it’s a double rad) Just wondering if the heat against the cable ties would be ok. I’ve seen the cable clips you can get but not much room for them. Any help appreciated

    Draining radiator?

    I’ve got this radiator that I need to drain down & remove to clean out due to sludge. Can I drain it with that drain valve on the left because as you can see that it connects to the radiator but that pipe also runs along past the radiator on the right?

    Radiator size

    Hi. Currently have 3 small double radiators (500x600) in our open plan living room/kitchen diner. Would like to change them for single panel designer radiators. Do I just need to double the size (1000x600) to achieve the same heat output? Thanks in advance for your help.

    Would one radiator in this space be enough for 6.5 x 3.8m room?

    Hi all! So I've got a 6.5m x 3.8m front room, it's an extension incorporating half of the original living room. I've worked out the BTUs needed but my question is will one rad in this space be enough? Putting two in at half the BTUs each will be a awkward mission but I'm a little apprehensive...

    Replacing one central heating radiator with two

    I want to replace one radiator underneath the window (which is useless when it's cold and dark becuase it's behind the curtains) with one tall radiator at each side of the window. I imagined plumbing them in parallel like this. (The dark squares in the middle are where the existing pipes go...

    What's happening to this radiator, paint flaking off?

    Rad is only a few years old. Paint is flaking away at the top curved section and it looks like faint spots of rust where the rad is now bare.
