Advanced Heater

The Advanced Residential Heater comes ready to install with built-in controls and a protective stone guard, making this an ideal heater for smaller sauna spaces. Built with a stainless-steel body, the Advanced Heater has a large stone cavity for maximum heat release, and the dual wall construction allows the exterior to remain cool to the touch. The easy-to-use built-in controls will enable you to set your heater up to 8 hours in advance. To experience a burst of humidity and to transform your sauna from dry to wet, sprinkle water over your heated sauna stones. This is an age-old Finnish tradition and safe to do on all ThermaSol sauna heaters.
