Tech Tips

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

Temperature Conversions:

Converting degrees Celsius to degrees Fahrenheit:         °F = 9/5(°C) +32
Converting degrees Fahrenheit to degrees Celsius:         °C = 5/9(°F -32)
Converting degrees Fahrenheit to degrees Kelvin:           K = (°F +460)/1.8
Converting degrees Celsius to degrees Kelvin:                   K = °C + 273


Conversion Factors:

1 KW = 1000 Watts
3412 BTU = 1 KW-HR
1 HP = 746 Watts
1 Boiler H.P. = 9.8 KW
