Cozy Heat O Thru-Wall Sauna Stove

This design allows you to mount the stove so that the firebox is accessible from an adjacent room or outside, while the main body of the heater remains inside the sauna. It effectively saves floor space inside the sauna room and keeps the mess of wood loading and ash removal outside your bathing area.

This unit is rated for sauna volumes between 317 and 635 cubic feet. Before purchasing, calculate your room's total volume to ensure it falls within this range, as an undersized stove won't heat properly and an oversized one can overheat the space.

The Cozy Heat O has a stone capacity of 353 lbs. You will need to purchase these stones separately, as they are not included with the stove.

Because this is a wood-burning appliance, it requires a certified chimney system capable of handling the temperatures produced by an 18 kW stove. You should consult with a local professional or your local building codes to ensure your chimney installation meets safety standards.
