    for saunas with 494-1271 ft³ adjusted volumeFor Saunas With an Adjusted  Volume of 494-1271 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 494 - 1271 ft³, which includes most 10+ 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 31.0 kW heater has sufficient power to heat your sauna.

    Harvia 36 DUO Pro Series Wood-Burning Sauna Stove & Fireplace (31.0kW)

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

    You have options! This table lists all of the heaters in the Harvia series and tells you the kW power and sauna size (adjusted volume) for each model.

    Model        Model
    Power        Power
    Adj. VolumeAdjusted Sauna Volume

    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

    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).
