Slim double radiator?

[xyz321]

Hi, I am. Looking to replace all 6 radiators in house. For replace mostly it will. Be type 22 (double panel double convector). Question is are there any brands which are slimmer than others? I just want to Minimise the wasted space.

Also are there any slimmer brackets for use?
Thanks

I like type 21 rads.

Have you done a heat loss calculation to check that you are buying the correct size rads? You may find your existing rads are oversized, so installing double convectors is unnecessary.

Thanks. No I haven't done calculations . Any recommended calculatiors? I tried a couple, one from plumbnation and other from. B&q and got different results for Btu required (difference was almost 20%). Not sure which one is right.
Thanks
