The figures above are based on a design of 0°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 table
above 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. |
