    I'd love to move this radiator from this wall to under my window in order to gain this wall space and also get the radiator to less obvious and more discrete place.

    From here...

    To this wall...

    I'm confident with plumbing radiators and if I had floorboards I'd be happy to move it if I could lift floorboard to run the pipes but as it's a solid floor, is it possible to still move it? Any help and advice is really appreciated please.

    You could just dig up the floor?
    It need not wreck the entire floor, I had to chisel the kitchen floor back so my gasman could accesss the cooker feed to move it. The screed isn't too hard.

    I also dug up about 6" wide x 8 feet when fixing parquet

    All my downstairs rads are fed from above, is that an option for you?

    Not a plumber.

    I wouldn't want to drop the pipes form upstairs as it doesn't look very nice having boxed pipes in my opinion.

    I'd be happy to chisel out in order to run the pipes but I'd need to know what dimensions I would to need to go for and then how to put the pipes back in. Thanks.

    Unless somebody who does this for a living chimes in, I would just chip away delicately to see where the pipes go.

    Size wise, you would be lucky to keep it under a couple of inches, depends on the pipes under the concrete

    Grinder or chasing machine on the floor to cut a chase wide and deep enough for two 15mm pipes with lagging on them.

    Or drop down from above and chase into the wall.

    Lots of dust and debris so room will need clearing and protecting as well as doors sealed up.

    Not sure why you're bothered about drop feeding from above, the pipes will be mostly concealed by the curtains.

    MikeCip & dilalio...

    A few questions...
    1. Would you suggest to use 15mm in copper or plastic?
    2. What are you thoughts on the lagging to use? Any suggestions?
    3. Should I be worried about any leaks? I guess I would try to do the run with no joints (only bends) in order to avoid the use of joints?
    4. You say to use one channel, would you not run two across the floor so the pipes start and end in the right place?
    5. What would you screed back over the channel using?

    PullerGas - I know what you mean about the curtains covering most of it but they would still be seen so I'd rather not if possible. Also, the carpet is coming up in the next couple of weeks for a laminate floor to go down so I thought this would be a good opportunity to do the floor work. I'm also not sure how many radiators upstairs are run from 15/22mm pipes so wouldn't know whether there would be enough pressure to feed that lounge radiator so I guess keeping the same configuration makes sure it'll work?

    Thanks for the all the ideas and help guys.

    Have you considered a vertical rad? Some of them are fully pumped and have quite high outputs afaik.
    Ask your plumber for advice or go to your local specialist rad supplier.
    Or just stack 3 small rads on top of each other in a ladder arrangement.:idea:

    Thanks Roger but I'm just looking to move the current rad over to the under the window rather than change anything. Thanks though.

    Copper, end feed, duct tape and felt lagging, one channel for both pipes about 70mm wide and 50mm deep. Back fill with a screed-type mix and trowel to flat.

    Thanks for that dialaio. So there's no need to worry about leaks a long as I do my solders well lag the pipes correctly? No need to bend I can just use right angle end feeds or would you advise to bend the copper instead? I saw a few examples of people using the while plastic pipe clips and the foam lagging. What's your thoughts on these? If I was to go down this route what size channel would you suggest? Thanks again, really appreciate the help/advice.

    I've just advised what I'd do.
    Test the pipes before backfilling and leave them pressurised for a day or so.
    Well soldered joints are as good as pure copper.
    Felt lagging is fine as you don't need such a deep chase.... hopefully you will have a good depth of screed before concrete else it gets very tough to chase... been there and done that and it knackers your breaker and chisels.

    Perfect, thanks. Good advice and suggestions, I appreciate it. You mentioned duct tape and felt lagging. are you meaning wrap the pipe in duct tape before lagging or it the duct tape just used to hold the felt lagging on etc? Also, would you take the pipes across the center of the room or does it not really matter? Thanks again.
