If the heat loss of the perimeter space is less than 450 Btu/hr per linear foot [430 W per linear meter] of outside wall, downdrafts are less problematic and heated air supplied through ceiling diffusers can provide a satisfactory solution.

Again, the rate of heat loss is used to determine the proper diffuser location. If the heat loss is between 250 and 450 Btu/hr per linear foot [240 and 430 W per linear meter] of outside wall, diffusers should discharge directly downward and blanket the perimeter walls with heated air.

If the heat loss is less than 250 Btu/hr per linear foot [240 W per linear meter] of outside wall, diffusers can be located in the center of the room and still provide adequate blanketing to handle the heat loss.
