So I’ve used a website to work out what heat output we need from radiators in a room we are renovating. We need 3120 watts in total. If I get 2 big double panel radiators (1.2m long)the combined heat out put is 4664 watts. The next size radiator down (1m long) would give a heat output of 3886.
Which size is best. Can you have too much heat output?
