The Science Behind Radiant Health’s Always-On Infrared Heating

Always On Infrared: Consistent Warmth, Perfected

Most infrared saunas use thermal switches that turn heater panels on and off as the sauna reaches temperature. This cycling creates unwanted fluctuations: when panels turn off, users feel an instant drop in warmth, and when they switch back on, users hear the distracting “click” of relays or fuses.

Radiant Health saunas solve this challenge with the development of always on infrared heating, a proprietary design that keeps heat constant, balanced, and quiet.

Why Continuous Infrared Heat Matters

The always-on infrared system was designed to perform more like a traditional sauna, maintaining a stable heat curve that enhances comfort and promotes steady perspiration.

• No Clicking or Cycling: The elimination of thermal switches means no “on/off” noise and no temperature dips mid-session.
• 30% More Distributed Heat: By optimizing heater wattage and adding new air-channel designs, Radiant Health achieved greater total heat dispersion without increasing energy draw.
• Faster Warm-Up: Rooms warm up in 20-30 minutes, a standard that bridges infrared and traditional sauna performance.
• Steady Infrared Signal: Continuous operation ensures the body receives a constant far-infrared wavelength between 7–14 microns, the optimal therapeutic range for deep tissue penetration and detoxification.

This balance of stability and safety allows Radiant Health saunas to deliver one of the most natural and comfortable heat experiences available.

How It Works

Radiant Health’s always on infrared system achieves its smooth heat delivery through precision design at every level:

1. Smart Heater Redesign: New lower-wattage panels (100–150 W) with increased surface area provide a broader heat field that feels naturally even.
2. Airflow Channeling: Built-in wall ventilation channels circulate warm air across each heater, ensuring uniform temperature throughout the sauna.
3. Dual Control Integration: Instead of a cycling thermal fuse, Radiant Health uses a dual thermal control system that combines a high-limit thermal switch and room thermostat for precision and safety.
4. ETL-Certified Safety: All heaters passed extensive testing to ensure surface temperatures remain within safe operating ranges, even under 10% overpower conditions.
   
   

Deeper Comfort With Low EMF and EF

Continuous heating doesn’t mean more radiation. In fact, Radiant Health saunas are designed for ultra-low EMF (≤2 mG) and ultra-low EF (≤10 V/m) levels.

• High-voltage components are relocated to the floor for increased distance from the body.
• Twisted and foil-shielded wiring minimizes electromagnetic interference.
• Printed grounding matrices ensure all panels are safely shielded.
• Every solder point and junction box is contained and grounded for consistent performance.
  
  

This integration allows Radiant Health to maintain always on infrared operation safely, with the lowest measurable EMF and EF readings in the industry.

Bridging Infrared and Traditional Sauna Performance

Traditional sauna users often crave the enveloping warmth of conductive heat, while infrared enthusiasts love the gentle, penetrating energy of far-infrared. The always-on infrared system unites both worlds, providing the steady ambient heat of a traditional sauna with the cell-level activation unique to infrared.

• Deep Sweating: As infrared waves continuously penetrate beneath the skin, the body warms from the inside out.
• Stable Ambient Temperature: The air remains comfortably heated without spikes or cool-downs.
• Improved Thermal Comfort: Even temperature distribution reduces “hot spots” and “cold zones,” especially around the lower back and legs.
• Energy Efficiency: Lower-wattage heaters and smarter distribution mean consistent performance at a reduced cost per session compared to traditional saunas.
  
  

Inside Radiant Health Saunas: A Quiet, Immersive Experience

Beyond performance, always on infrared  creates a noticeably calmer environment. The quiet absence of switching noises allows for full relaxation.

The result: a sauna that simply feels better. Your body stays in flow, your mind stays present, and your sweat response is natural and continuous.

Proven Performance and Certification

Each Radiant Health sauna model using always on infrared heating has been certified to UL 875 and ETL standards for electric dry-bath heaters, ensuring:

• Controlled maximum heater surface temperature
• Safe operation at up to 105% rated input
• Verified insulation and grounding continuity
• One-hour automatic safety timer
• Moisture resistance through water spray and dielectric voltage tests
  
  

These rigorous standards ensure the advanced heating system not only performs beautifully but also meets the highest expectations for safety and reliability.

FAQs

• What makes Radiant Health’s always on infrared different from other infrared saunas?
  Most infrared saunas use cycling heaters that turn on and off during use. Radiant Health’s Always on infrared keeps panels gently energized, maintaining continuous warmth and eliminating temperature drops or clicking noises.

• Does Always On Infrared use more energy?
  No. The system uses optimized, lower-wattage panels that balance total energy draw while delivering 30% more distributed heat. It’s both more efficient and more comfortable.

• Is continuous infrared heating safe?
  Yes. Each sauna is ETL and UL-certified, ensuring the heater surfaces never exceed safety thresholds even under over-power conditions. Radiant Health’s low EMR and EF levels also exceed international safety standards.

• How does it feel compared to a traditional sauna?
  The sensation is similar in warmth but smoother and less harsh. Always on infrared creates steady, deep heat that feels consistent from start to finish, without the sharp “blast” of hot air found in traditional saunas.

• Does every Radiant Health sauna include Always On Infrared?
  Yes. All current Radiant Health sauna models feature always on infrared technology as part of their advanced heating design.
