Heaters Help

If you do not know how much BTU you need to heat your space a simple formula can be followed:

1. Figure cubic square feet of space to be heated

Length x width x height
Example: 50' long x 30' wide x 15' high= 22,500 cubic square foot of space

2. What is the average temperature outside?

This could be approx
Example: outside temp is 15 degrees

3. What do you want the temperature to be in the building?

Example: 55 degrees

4. .The heat rise is (55 degrees inside - 15 degrees outside) = 40 degrees.

5. Multiply the cubic square foot by the heat rise.

22,500 x 40 degrees =900,000

6. Multiply by .133

.133 x 900,000 = 119,000 or approx 120,000 BTU./HR needed to heat the building
