Anyone able to point me to a source of radiator output figures please?

I've got an old double radiator 600mm x 1920mm (no fins) that I need to
replace and want to match the output.

Radiator manufacturer web sdites.

Find something close to what you have. Scale it's output in terms of area.

If you have a conventional boiler running at 82 degrees, then the
actual heat output is about 80% of the nominal quoted figure

Thanks. I've done that but I can't find any listings which include
radiators without fins.

Looking at figures for double panel with single fins and a single
panel no fins; a figure of 2200 watts would seem a reasonable guess
for a 600mm x 2000mm double panel rad.

If replacing one rad , there is no need for an accurate calculation.
Consider whether the present one gives enough heat out on the coldest
days and whether it heats the room up quickly enough and adjust
accordingly.

Also what space do you have available, do you want a physically
smaller rad ....

If in doubt go for a higher output, the extra cost is negligeable.

Although they don't do double panels without convectors now you can get
a reasonable guide by doubling the figures for a single panel and taking
away 10%. This is roughly the difference you see in figures between single
and double convectors.

Thanks, that's what I'm doing: no need for a calculation when I've got
empirical evidence.

You're welcome

Don't forget that it doesn't matter if you oversize within reason.
For example, you could get the same heat output for smaller wall area
by going for a single panel radiator with fins or get a bit more in
reserve by going for one of the same size with fins.
Once you put a thermostatic valve on the radiator, all that will happen
is that the room will warm up a little faster and then the TRV will
back it off.
That may be attractive.
