central heating radiators

[dan007]

I want to replace my combi boiler in my house is there a way i can work out the btu rating of each of my radiators they are all fairly new but i dont know there btu outputs .
I wondered if there is a formula using the height of the rad and the width of the rad and whether they are doules or singles to calculate these.
All the plumbers merchants have calculators and charts to work out what size rads i need for each room, but i want to check the ones i already have to see if i can reuse ant of them please help
