Select the Baseboard
Read the manufacturer’s literature. Find the rating per linear foot of baseboard at the average water temperature. Find the required length of baseboard for each room by dividing this rating into the room heat loss. You may specify any water temperature the heat source can maintain. If you use lower water temperatures, you will have to install more baseboard. If you install more than the required amount of radiation, you will overheat the room. heating the walls and windows prevents drafts and increases the feeling of surroumding warmth, so place the radiation under thewindows and on the walls.
For example: You might choose to use a design water temperature of 200F. You calculated that the heat lost from the roomsurfaces during the average coldest days is 3810 btuh. The baseboard rating (from the example rating table 1 below) is 710 btuh per linear foot at 200F.

Install a total of 6 feet of baseboard in this room. (3810 divided by 710 equals 5.4 linear feet of baseboard required.)
