Cozy Heat Thru-Wall Sauna Heater

The heater is installed through a partition wall, allowing you to feed firewood into the firebox from an adjacent room or outside. This keeps your sauna interior clean from wood debris and ash while maintaining a clutter-free aesthetic.

The Cozy Heat heater is designed with minimal safety clearances, making it suitable for smaller sauna spaces. However, you must always consult the included installation manual and your local building codes to ensure proper distance from combustible materials.

This model requires 265 lbs of sauna stones. Using the full capacity is essential for achieving the signature mild, long-lasting heat that this heater is designed to provide.

Yes, the unit features a top flue connection and includes a chimney pipe, but it must be connected to a properly rated chimney system. We recommend having a certified professional handle the installation to ensure the flue meets safety and ventilation standards.

The heater is engineered for 6x cleaner smoke emissions and higher fuel efficiency, which results in significantly less creosote buildup in your chimney. While you will still need to perform routine inspections, the cleaner burn reduces the frequency of heavy-duty chimney cleanings.

The 5mm stainless steel flame cutter is built for longevity and high-heat resistance. It is designed to withstand the intense thermal stress of daily wood-burning cycles, ensuring the structural integrity of the firebox over time.
