There are lots of heat loss calculators on the www that will help you calculate the requirements. Just know your delta T so that you can pick the correct one. E.g. for a given room with the same heat loss, a radiator on a condensing boiler would need to be about 40% larger than one that would be running hotter on a standard boiler.
