Note:
The amount of heat introduced into the room is dependent upon the 'Free Area' of the register or diffuser. When they have been in use for a number of years, the free area is reduced by decorating. This reduction can be as much as 50%. Therefore, improvements can be made to an existing system by simply replacing the registers or diffusers.
