General Guidelines and Rules of Thumb:
Quick heat loss calculation: A general rule of thumb for Primary Heating of an insulated commercial or residential room is to use 10 Watts/SqFt of heat.
Example: a 10ft x 10ft room is 100 square feet.
100 x 10 W/SqFt = 1000 Watts.
Note: Supplementing existing heaters such as a forced air furnace system would require less wattage.
Quick IR outdoor heat loss calculation: A general rule of thumb for outdoor heating using quartz lamp infrared heaters is 2 W/SqFt will yield approximately a 1°F perceived temperature rise.
Perceived 10°F Rise requires 20W/SqFt of Infrared heat
Perceived 20°F Rise requires 40W/SqFt of Infrared heat
Perceived 30°F Rise requires 60W/SqFt of Infrared heat
