Sauna Heaters Sizing & Selection

Measure the length, width and height (in feet) of the sauna. Multiply the three measurements together to get the basic room volume in cubic feet.


Divide the CUBIC FOOTAGE BY 50 = Kilowatts Required

(Select the next size of Saunacore model stove which exceeds the calculated room cubic feet.)

7ft length, 5 ft wide, 7 ft high (7 x 5 x 7 = 245)
245 divided by 50 = 4.9 KW
A 5 KW (5000 WATT) is required.

If there is any doubt in size, we always recommend the next larger size. (This is a general guideline.)


Ventilation System [IMPORTANT!]

Ventilation in a sauna room is extremely important to achieve the utmost in satisfaction and pleasure. It will also speed up the preheating of the sauna room. Lack of fresh air due to insufficient ventilation or poor management of ventilation can create an uncomfortable feeling. This often results in the symptoms of difficulty in breathing or burning of the skin. 

The expanded hot air in the sauna contains proportionately less oxygen than the denser atmosphere outside. Bathers sometimes experience faintness unless the air is changed regularly. An amount of fresh air enters each time the door is opened; this is insufficient, however. Normally two ventilators are built into the walls. 

The diagram shows the proper location of the vent openings. The inlet should be located below the heating unit (or close to it) and the outlet is located on the opposite side, on the ceiling or just below the ceiling. Recommended ventilation openings are 4” to 6” diameter, depending on the size of the sauna room.
