    Cozy Heat

    A complete heater-and-stones package

    This Cozy Heat O Thru-Wall package combines the exact wood-burning stove with the stone quantity assigned to that model. Choose 12 or 18 kW, then split-face or rounded olivine diabase stones. A chimney system, floor/wall protection, and model-specific installation components are separate.

    Package option Stone boxes Manufacturer stone mass
    12 kW + split-face stones 5 boxes 243 lb required by the current model drawing
    12 kW + rounded stones 5 boxes 243 lb required by the current model drawing
    18 kW + split-face stones 8 boxes 353 lb required by the current model drawing
    18 kW + rounded stones 8 boxes 353 lb required by the current model drawing

    Current rounded-stone source data conflicts on per-box weight: one field says 44 lb while the included-items, product-weight, and shipping-weight fields say 33 lb. Sauna Marketplace therefore publishes the exact package box count and the heater’s required total stone mass, but does not promise a per-box rounded-stone weight until the source is corrected.

    Choose the heater size first

    12 kW covers 212–424 cu ft; 18 kW covers 318–636 cu ft. Adjust for glass, masonry, tile, concrete, and massive-log construction using the current Cozy manual before selecting a package.

    Installation resources

    The Manuals & Documents tab contains the current English installation and operation manual, inch-reference edition, limited warranty, and exact drawings for both heater sizes.

      PLAN THE WHOLE SAUNA

      The room and heater still have to work as one system.

      Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.

      Compare sauna heaters

      See electric sauna heaters by output, stone mass, control style, and installation type. Size from adjusted room volume, not floor dimensions alone.
