Air channels between the outer mantle and core guide the air heated in the fire box through
slits into the stone compartment.The result is quick,smooth heating of the saunastones which, in
turn, ensures plenty of steam and effective heat circulation for the sauna. As the fire dies down,the fire box walls cool and the air stops rising to the stone compartment (the Coanda effect).
This keeps the cooling effect away from the stones, helping them retain their heat longer.
Surprisingly, the hottest part of the stove is not the top of the fire box but the back wall, where the heat gets sucked due to the air flow. All Kastor stove have an air guide plate in the back of the fire box. This not only reinforces the hottest, most stressed point of the stove, it provides an insulation layer that improves heat capture and saves on wood. Air Guide sets off/control fire and woods are not burning too fast.
DEEP AND OPEN STONE COMPARTMENTS
Water should come in contact with hot stones—not metal —to generate billows of soft, rich steam. Our sauna stoves are designed with deep and wide stone compartments that ensure water hits stones without contacting the metal walls and cooling the heat source. Besides smoother steam output, the deep stone wells store more heat more effectively, saving on wood.
DOUBLE MANTLE CONSTRUCTION
The Kastor Incendo sauna stoves boast an advanced double mantle structure, in which air flows between the inner and outer mantle. The inner mantle insulates heat from the outer mantle, which stays safely cooler. Although the outer mantle does heat up as temperatures rise in the sauna, it never gets as scalding as the inner walls can—which means you can plan a sauna with smaller safety distances than usual and make more use of your sauna interior.
