1 How Much Heat Do You Need?
Estimated Heating Area information included on this guide assumes the area to be heated has a 10 ft ceiling.
If the area to be heated has a higher or lower ceiling, calculate the amount of BTU’s required by using the following method:
TEMPERATURE
RISE = 42ºC
1. Measure the space’s dimensions to determine |
cubic feet. (Length x Width x Height = Cubic Feet) |
CUBIC FEET
BTU’S REQUIRED TO HEAT SPACE TO DESIRED TEMPERATURE
2. | Subtract the outside temperature from the |
| desired inside temperature to determine the |
| temperature rise. |
3. | Use the chart on the right to match the size of |
| the heating area (cubic feet) with the desired |
| temperature rise to find the amount of BTU’s |
