Hi.

I have an old single panel non convector rad in my dining room which is
150cm wide and 64cm tall. Anyone know what the BTU output of this rad would
be, so I can spec a new one.


TIA

3700 +/- quite a bit.

Older radiators are less efficient than their modern equivalents, so
there's no formula which directly converts rad size to output
(model/brand will affect it too). Suggest you'd be better off starting
from first principles and calculating how many BTUs you need for the
room (plenty of calculators available online).

If you fitted a new one of the same dimensions, it would certainly be
more efficient than the one you've got, so at least the room wouldn't be
cold...

Ignore the size of the old one and calculate the rad size required
from the size of the room.
There's nothing to say the old one isn't incorrectly rated.

Thanks. The room is semi open plan joining the lounge. Do I just size the
room as if it was self contained and take into account windows, etc?

Assuming the adjoining room has been calculated in the same way yes.
If the room through the other half has a woefully underspecced rad
then it might be worth changing that one too.

The lounge was "re-radded" by the plumber a couple of years ago, so that is
up to date.

Thanks for your help
