The description, wattage and schematic indicate that this unit has 10 heaters. However from the pictures it looks like the same heater configuration on the walls as your 8 heater (darker wood) unit. Is this just an error in the photo or ???
" The picture is still from the previous version of this model. The new version has 6 wall heaters instead of the 4 as seen in the main photo. Your sauna will definitely have the 6 wall heaters as that is all we stock now for this model. "
