Efficient Wood-Burning Heating
At the center of the Model S6B is a high-efficiency stainless steel wood-burning stove engineered to transfer heat into the water without requiring an electric heater.
The stove uses a secondary combustion chamber to capture additional heat from the combustion process. SaunaLife states that this design can reduce wood consumption by up to 50% compared with conventional wood-fired hot tubs while helping accelerate the heating process.
Cooler water enters the heater through a lower channel and heated water returns through an upper channel, creating natural circulation and helping distribute heat throughout the tub.
Fast Heat-Up Time
Under SaunaLife's stated operating conditions, the wood-burning heater can heat the tub's 436 gallons of water from approximately 40°F (5°C) to 95°F (35°C) in approximately 1.5 to 2 hours. Actual heating time can vary based on outdoor temperature, starting water temperature, fuel quality, wind, and operating conditions.
