     ### Step-1# Calculate your room volume 

The sauna heater, being the heart of the sauna, must be the correct wattage to be efficient and to meet electrical codes. To determine the heater you require, calculate the room size and use the chart below for reference.

Example: a sauna room measuring 5 ft X 6 ft X 7 ft high, equals 210 cubic feet. This room will require a model SE-5 heater.



















### Step-2# Pick the matching heater and control
