I have a ferroli Falcon boiler in situe in my two bedroom house. I want to put bigger convection rads in some of the rooms. The user manual for the ferroli falcon boiler says that the heat output is 23,3 KW / 9,7KW and the heat output is 25,8KW / 11,5kw. I have added up the btu for the existing rads which is 20,056 btu / 6,665 watts. do i have the capacity to upgrade?

Yes you do, just watch the amount extra that you put on.
