This 1500W far-infrared sauna heater is designed for dry sauna rooms and uses a graphene heating system that combines convection with far-infrared heat. Under laboratory test conditions, it can reach temperatures up to 70°C, and it operates without traditional sauna stones, so there is no need to add, replace, or maintain stones. The 110-120V plug-in design simplifies installation compared with many traditional sauna stoves, and the natural Hemlock wood enclosure blends easily with wood sauna interiors while helping isolate users from the internal heating components. Temperature and operating settings can be adjusted from the built-in touch panel or through compatible Wi-Fi smartphone control, and the heater can also be operated normally without Wi-Fi. Over-temperature protection and tip-over automatic shut-off provide additional protection during normal operation. This heater is recommended for small 1-2 person dry sauna rooms with an interior volume of approximately 35-105 cu.ft.
