Suggested Heat Load
Example:
A work counter for light assembly is 15 ft x 25 ft. (4.5 m x 7.6 m)
Ambient air temperature 40°F / 4°C, located near shipping doors.
Approximately 170 BTU/hr/sq. ft x (15x25) sq. ft = 63,750 BTU/hr
Two heaters at opposing locations would be preferred
Full Building Heat
Calculate the total heat input required, ensuring the inclusion of any unheated make-up air due to exhaust fans.
Use the following chart as guidance to heater placement.
