To determine the necessary size, or Kilowatts, of the sauna heater required, measure the length,
width and height (in feet) of the sauna. Multiply the three measurements together to get the room volume in cubic feet:
L x W x H = Cubic Feet
Cubic Footage divided by 50 = Kilowatts Required
(always select the next size larger sauna
heater which exceeds the calculated room cubic feet.)
Example:
7 ft length, 5 ft width, 7 ft height (7 x 5 x 7 = 245)
