How much heat do you need?
Calculate the amount of BTUs required by using the following method:
DESIRED INSIDE TEMPERATURE
- OUTSIDE TEMPERATURE
= TEMPERATURE INCREASE
1. Measure the space's dimension to determine cubic feet.
(Length x Width x Height = Cubic Feet)
2. Subtract the outside temperature from the desired inside temperature to determine the temperature increase.
3a. If you have measured temperature in FAHRENHEIT, calculate the required BTUs with this formula:
(cubic feet x temperature increase x .133 = Required BTUs)
3b. If you have measured temperature in CELSIUS, calculate the required BTUs with this formula:
(cubic feet x temperature increase x .2394 = Required BTUs)
