"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 177 - 318 ft³, which includes most 3-4 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 6.0 kW heater has sufficient power to heat your sauna.

Adj. VolumeAdjusted Sauna Volume
This column shows the maximum adjusted sauna volume (after an adjustment to account for "cold surfaces" in the sauna) for which each sauna heater is rated. "Adjusted sauna volume" is the volume (i.e. Width x Depth x Height) of the interior of a sauna PLUS an adjustment 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 (for example, if your sauna has lots of windows). Want to verify your sauna's adjusted volume? Use this 20-second calculator to make sure the heater you buy has enough power (measured in kilowatts, or kW). Adj Volume |
Sauna SizeMaximum Sauna Size
This column provides a quick-reference estimate of the maximum sauna capacity (i.e. 3-person sauna, 4-person sauna, etc.) for which each sauna heater is rated. Again, this is only an estimate 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 (which is much more precise) to make sure the heater you buy has enough power (measured in kilowatts, or kW).
