# How the Radiant Health Always-On Infrared Heating System Works

Radiant Health’s Always-On Infrared Heating System delivers smooth, consistent warmth through precision engineering at every level: 

1. **Smart Heater Design**:   
   Redesigned lower-wattage heating panels (100–150 W) with increased surface area create a broader, more evenly distributed heat field for enhanced comfort.
2. **Optimized Airflow Management**:   
   Integrated wall ventilation channels circulate warm air across each heater, promoting uniform heat distribution throughout the sauna.
3. **Advanced Dual-Control Technology**:  
   Rather than relying on a cycling thermal fuse, the system utilizes a dual-control design that combines a high-limit thermal switch with a room thermostat for precise temperature regulation and enhanced safety.
4. **ETL-Certified Performance and Safety:**   
   All heaters undergo rigorous testing to verify that surface temperatures remain within safe operating limits, including under conditions of up to 105% of rated input power.
