Load Calculation For Gas Fired Radiant Infrared bleating for Commercial, Industrial, Agricultural, and Military Applications

The capacity of a gas, radiant tube-heating system depends upon the value of the heat loss. Our program needs to learn some basic building specifications, geographic locations, and the desired indoor temperature. Complete the following form and our program will create a report with an estimated heat loss for the building, and annual fuel cost comparison between traditional forced air heating versus our gas, radiant tube-heaters.

Equipment Sizing

OUTSIDE AIR

Are you using outside air for combustion?
(This will be used for capacity sizing. As a general rule, using outside air adds 3% to the total load.)

No Yes

MOUNTING HEIGHT

What is the mounting height of the heaters?
(As a rule for Infrared heating, for every foot over 15 feet, the total load is increased by 1%.)

(The efficiencies listed are "Cyclic" efficiencies. This is defined as an average efficiency for an average system run time (15 min.).)

Omega II® (85% efficient)
Reflect-O-Ray® (90% efficient)

Note: The heat loss calculation program is derived from data supplied by the user, and our heat loss is intended to provide estimates only. An annual fuel audit would be required to obtain precise fuel consumption data.
