Just clean, efficient DC Sauna™ heat.
Sauna Anywhere the sun shines.
Why Change Now?
Save money: the DC Sauna Heater™ pays for itself in energy bill savings! From longevity and longer warranty; to low voltage safety; and the environmental reasons are vast. Knowing your sauna sessions aren't a burden on the planet is valid and powerful. The reduction of "eco-stress" is a real health benefit AC saunas can't claim.
Join the DC Sauna™ Revolution!
For decades, AC sauna heaters in the U.S. have been limited by outdated grid-based architecture: high electric bills, no drains, no ventilation, and warning signs telling users not to pour water on the heater. These failures come from flawed room design, not tradition or as a result of the technology.
DC Sauna™ technology eliminates every limitation. Our heaters are fully waterproof and engineered for heavy water use, proper löyly, and real heat. With Solar-Sauna™ LLC Kits, daily sauna use becomes free, clean, and carbon-independent. AC saunas waste energy. DC saunas create energy independence.

Most American gyms run at 145–155°F, preventing the temperature-based gains proven in long-term research.
The DC Sauna Heater™ is engineered to produce the temperatures needed for measurable results.
Major peer-reviewed health benefits include:
• Reduced risk of heart attack, stroke, dementia, and Alzheimer’s
• Lower inflammation and blood pressure
• Increased heat-shock proteins and cellular repair
• Improved cardiovascular performance
• Faster athletic recovery
• Better mood, better sleep, stronger immune system
• Longevity gains confirmed in long-term studies
