for saunas with 318-635 ft³ adjusted volumeFor Saunas With an Adjusted Volume of 318-635 Cubic Feet (ft³)
"Adjusted volume" is the interior volume of a sauna (i.e. Width x Depth x Height) plus an adjustment to account for "cold surfaces" in the sauna (i.e. glass, tile, stone, etc. — but not including the floor). This adjustment is typically around +20% but can be more if your sauna has lots of cold surfaces (i.e. multiple large windows).
This heater is rated for use in saunas with an adjusted volume of 318 - 635 ft³, which includes most 7-8 person saunas (based on average sauna sizes, layouts & interior cold surfaces). Your sauna may differ. We strongly recommend taking 20 seconds to verify your sauna's adjusted volume to ensure that this heater has sufficient power to heat your sauna.
If your sauna's adjusted volume is more or less than this heater's 318-635 ft³ range, click here to see other kW powers available for this same heater.
