Gas Sauna Heaters

A gas sauna heater is a powerful way to heat a traditional sauna, offering fast warm-up times, strong heat output, and excellent steam potential. Gas sauna heaters are a popular option for larger sauna rooms, commercial sauna builds, and installs where customers want reliable performance without relying on electric heating elements.

Our gas sauna heaters can be configured to run on either natural gas or liquid propane, giving you flexibility based on your home or facility’s fuel source. Whether you’re building a residential backyard sauna or upgrading a high-traffic commercial sauna, gas heating delivers consistent high-temperature performance.

Choosing the Right Gas Sauna Heater Size

Gas sauna heater sizing depends on your sauna room’s cubic footage, insulation levels, and the amount of glass or exterior wall exposure. If your sauna has a lot of glass or poor insulation, it’s usually best to size up for better heat-up time and stronger overall performance.

• 40,000 BTU gas sauna heater: Best for medium-to-large sauna rooms
• 80,000 BTU gas sauna heater: Best for large sauna rooms and commercial saunas

Installation Requirements (Important)

Gas sauna heaters require proper ventilation and combustion air to operate safely. These heaters require fresh air intake and exhaust venting to the outdoors and must be installed by a licensed HVAC professional.
