Are 48″ Baseboard Diffusers necessary?
Doing flooring and have pulled out the baseboard diffusers from 1959 house. They are 48″ long but the hole in the floor is only 2″ x 12″. Can I replace with a smaller size or is the 48″ length helping to spread the warm air around the room? Note that there are 2 of the 48″ diffusers along the same wall in the 14′ x 17.5′ living room.
Thanks in advance!
