Infrared Heaters / Emitters
A number of sauna companies have extensive woodworking experience, but no other sauna company comes close to our extensive experience in either health or electronics. That experience means our custom emitter designs are only ready for use in products once they meet our strict requirements for efficacy, functionality, durability, and safety. Efficiency in heater design, relatively speaking, is not difficult from an engineering perspective. After those considerations, the remaining variables can be decided by personal preference.

What to Avoid in Infrared Emitters
NEAR INFRARED (NIR)
LOW DURABILITY / LOW RELIABILITY
Ceramic block and ceramic rod heaters are prone to absorption of moisture over time, ultimately leading to their failure and need for replacement. Their fragile nature also means they can break during transportation. Our Bio-Resonance ™ heaters inside our Thermal Life saunas use Ceramic Inside Metal Sheath heaters that do not have these problems.
Typical carbon (sometimes called “laminant”) heaters do not have very good reliability and will fail over time too. The reason is that they are not manufactured and tested to meet high enough tolerances. Unlike ceramic-style heaters, which require significant manufacturing knowledge and investment to produce, carbon heaters can be made inexpensively enough that the same factory that does the woodwork almost always makes the heaters too. As you would expect from people skilled in woodwork and not heaters, the typical depth of knowledge is very limited. An unfortunate side effect of all this is that the factory can make enough extra profit on the heaters that they can afford to simply replace heaters later when they fail, as opposed to needing to design in reliability to begin with – they count on the fact that there is no way for a consumer to know whether they are buying one built to be reliable or not, and that many people will not bother to get their sauna fixed in the future. Our Bio-Resonance C™ heaters used inside our Transcend saunas are carbon heaters designed, manufactured, and tested to be durable and reliable and worthy of our name. We extensively rely on word-of-mouth to conduct business and therefore have a reputation to protect – that means we have no choice but to design in reliability.
One of the biggest drawbacks to carbon heaters is their exceptionally high EMF compared to other heater technologies. Carbon heaters have been around for as long as far infrared saunas have been around, but without solving the EMF problem, High Tech Health would never consider using them. The ONLY WAY to reduce the EMF on a carbon heater is to do it by design. You can tell if a company has designed their carbon heaters this way because the result is a heater that emits virtually no EMF. Our Bio-Resonance C™ heaters, the carbon-style heaters that are found in our Transcend saunas, by design emit virtually no EMF.
Other Heater Considerations
After solving the important engineering problems inherent to carbon-style heaters (high EMF and low reliability, described above), we asked our designers to explore what could be done with them. Our Transcend sauna, with its unique geometry, is the result and it is only possible with the use of carbon-style heaters. Other heater technologies would have been too bulky to use and impossible to hide in walls with so much glass. Furthermore, any other heater would have robbed the design of some of its elegance and simplicity.
