I am going to replace an old radiator and I was wondering if anyone would have an idea what its output would be as I can't find any info about old ones.
Really does not matter what the output of old/existing radiator. The thing that matters, is that you size the radiator correctly for the heat loss of the room.
It could well be that it was never done correctly.
