Calculating BTU of radiator

redser7 · 2015-03-13 12:54:44

Hi - I wonder is it possible to calculate the BTU of an existing radiator (approx. 15 years old). It is a double rad 110 cm long x 45 cm high. We're getting an extension in a while and want to keep this rad so want to work out how much extra heat we will need for the new layout. Cheers

You must be attaching a blow heater to it.
