The above figures are for a design of 0 degrees F.
Add the following watts per square foot for the following temperatures below zero.

-5       Add 0.75 watts per square foot.
-10      Add 1.50 watts per square foot.
-15      Add 2.25 watts per square foot.
-20      Add 3.00 watts per square foot.

IMPORTANT: The above table is designed for a mounting height of 9 feet above floor level. For higher mountings add 10% of the total watts for each foot above 9 feet. For lower than 9 feet mountings deduct 10% of the total watts for each foot below 9 feet.
