One for the plumbers / Heating engineers

I gave the example as a real word example, the OP mentioned the calculators were giving a huge range. Just checked the spec, 5593 BTUs / 1639 Watts. The room is 15 sq/m with 3 outside walls. It's never cold & the rad is usually set to 4 out of 5. Obviously it's better to have a rad you can turn down rather than one that is too small. In my experience the "designer" ones tend to have lower outputs so you really need to check.

I don't know what the output of the radiator is but it's a vertical designer type double flat panel 1800mm x 400mm, do you think that will be ok.

If it turns out that it's not enough is there somewhere you could put another radiator - could you get the pipes to it etc?

It's tough to know - maybe there's quite a bit of heat coming from your existing kitchen diner. Our ('normal' size) kitchen doesn't have a rad in at all. The plumbing is nearby but we just never got around to fitting the rad and then determined that it didn't need it.

OTOH I was worried that our large and north facing living room would be cold. Put two chunky rads and the tubing for a third buried in the wall but never fitted it. It does take some time to warm up but we don't use that room during the day so it's not an issue.
