The output of a radiator is measured in square feet of radiation. To determine the number of square feet of radiation in a radiator:

1.Measure the height of the radiator.

2.Count the number of columns in a section.

3.Count the number of sections.

Multiply the total number of sections by the number of square feet per section as shown in the following tables:
