Ceramic heaters

Ceramic heaters consist of a husk made of white or black ceramic which is about 30 – 65 centimetres long and 12 to 14 millimetres in diameter. The husk is about 2-3 millimetres thick. Ceramic is a kind of porcelain that has been baked at very high temperatures. The husk consists of a mix of 15 different minerals, sand and magnesium oxide. Inside is a coiled tungsten wire, which – if pulled straight – would be 16 metres long. Each heater is placed inside a shell that consists of a concave reflector made of polished aluminium.

Ceramic heaters were first used for commercial infrared cabins in Japan in the 70s.  These were generalized forms of medical heaters developed by Dr Tadashi Ishikawa. The spectrum of infrared heat they emitted correlates with the natural spectrum of a hot stone mass such as they were used in Indian sweat lodges or in traditional soap stone ovens. This is why they are also known as organic ceramic heaters. For more than 40 years ceramic heaters have proven to be secure and efficient.

Ceramic heaters contain a progressive structure of different infrared frequencies. They radiate a pleasant and soft energy which deeply penetrates the skin and feels like natural warmth and comfort.


IR-C 87% long wave (“far” infrared)
IR-B 22% medium wave  (“medium” infrared)


Like ceramic heaters, heaters made from stainless steel, aluminium or Incoloy® belong to a group of long and medium wave dark heaters. The percentage of effective short waves is minimal and they will only become active towards the end of the session when the heaters reach maximum temperature.

The structure of the heater is nearly identical to a ceramic heater but the husk that surrounds the coiled wire is made of stainless steel, aluminium or Incoloy®. The husk is about 7 millimetres in diameter and 0.3 millimetres thick. There is only pressurized magnesium oxide inside and around the tungsten wire. Outside the metal husk is a thin ceramic sheet to create infrared frequencies. Unlike ceramic heaters metal heaters can be manufactured in different shapes. It is necessary even to create U- or M-shaped husks to manipulate the temperature and length of the heating element into creating the same frequencies as a traditional straight ceramic husk.

Incoloy® is a popular version of a stainless steel heater.  Incoloy® is a registered trademark held by the American Special Metals Corporation which manufactures this nickel-chromium-aluminium alloy. Incoloy® is not directly related to infrared heat but merely used as a stable alloy for manufacturing electric resistance in chemical industries. Incoloy® resistances can be found in many household goods, for example to heat water for the dishwasher or coffee machine or to grill meat on an electric grill. To create healing infrared frequencies a regular Incoloy® resistance has to be covered by a ceramic sheet and formed to a certain length. Incoloy® are U- and M-shaped and built into reflectors. Compared to ceramic heaters Incoloy® heaters emit a little less medium and short wave infrared heat.


IR-C 95% long wave
IR-B 5% medium wave


The best-known Full Spectrum heaters are Philips Vitae lamps. Unlike the “dark radiators” described above these lamps emit visible red or orange-yellow light. The tungsten wire is not covered by a ceramic or metal husk but by a glass husk like a halogen lamp. No thermal isolators like sand or magnesium oxide are being used.

Our Full Spectrum lamps emit a maximum of 27% short wave radiation and thus a lot more than ceramic or metal heaters. This helps the body to warm up much faster and boosts long-term efficiency. An infrared cabin equipped with these heaters doesn’t have to be pre-heated and causes the same intensive sweating of the body in 15 minutes for which a cabin equipped with dark radiation heaters will need 30 minutes.

Short wave heaters penetrate the skin deeper, in some cases up to 6 millimetres. During tests under laboratory conditions it is possible to create temperatures of more than 1650 degrees with 80% IR-A and water-cooled lamps. Penetration of more than 6 millimetres could be observed in dead organic matters. Short wave heaters are therefore often used for therapeutic treatment as people report a reduction of pain in their joints and muscles.

Full Spectrum heaters have another advantage in that they don’t need to be pre-heated. A session is much shorter compared to long wave heaters thanks to the Full Spectrum’s high intensity. As a general rule Full Spectrum heaters are used for medical and therapeutic treatments while long wave heaters are used for relaxation.


IR-A 27% short wave
IR-B 58% medium wave
IR-C 15% long wave


Duo heaters are heaters that contain two different heaters in one shell. Our duo heaters consist of one magnesium heater and one Full Spectrum heater, so you get the best of both worlds. Choose between both with the simple press of one button.
