    for saunas with 106-177 ft³ adjusted volumeFor Saunas With an Adjusted  Volume of 106-177 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 106 - 177 ft³, which includes most 2-3 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.

                                                    Like this heater but need more (or less) kW power?

                                                    You have options! This table lists all of the heaters in the HUUM Steel series and tells you the kW power and sauna size (adjusted volume) for each model. Please note that while the Steel Mini 4 is a "standing wall mount" heater (meaning it sits on the floor but is right up against the wall), the Steel 6, Steel 9 and Steel 11 are all free-standing heaters.

                                                    This column shows the adjusted sauna volume range for which each sauna heater is rated.

                                                    "Adjusted sauna volume" is the volume (i.e. Width  x  Depth  x  Height) of the interior of the 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 multiple large windows).

                                                    Want to verify your sauna's adjusted volume?  Use this 20-second CALCULATOR to make sure the heater you buy has the correct power (measured in kilowatts, or kW).                                                     Adj. Vol.Adjusted Sauna Volume

                                                    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).
