I'm thinking of getting a stove and running 4 double rads from it ..
I can measure the size of the existing rads, from that, how do I calculate the BTU of each rad ? - I assume I need to total all the rads BTUs to determine what size stove I need ?..
Also, when a spec of a stove mentions it can run 6-8 rads - does that means single rads or double rads ?
Go to plumb center and beg one of their catalogs, this will give you a fair guide to the output of different sizes of radiator.
The stove you are considering should give the specified output from the back boiler - you can then see how many radiators it will run (if it is a multifuel stove the output will be linked to a percentage of full firing output.
