Hi there,
Would anyone happen to know how you calculate (roughly) the BTU output rating of a radiator, when all you know is it's size?
e.g.
530mm x 1450mm (single panel, convector)
530mm x 1450mm (single panel only)
700mm x 950mm (double panel convector)
530mm x 1550mm (double panel convector)
There seem to plenty of online calculators for working out what BTU you need (calculated by room size, etc), but I can't find any for working out what you've actually got! (calculated by the dimensions of your existing radiator).
Many thanks
