Semi IKI stove is best suited for smallish, 7-12 cubic metre sized, saunas. Semi IKI has a fire pipe extension on the top of the furnace the same way as the Mini IKI stove.The fire pipe is surrounded by stones and throwing water on the pipe gives a warm, relaxing steam. However throwing water on the lower part of the stove makes for a much hotter and highimpact steam. In the Semi IKI stove the amount of stones can be up to 180 kilos depending on the size of the individual stones. The distinguishing feature of the Semi IKI is the notably larger furnace, which enables the burning of longer pieces of wood. Air flow can be easily controlled by a switch on the door.
