Sauna heaters
Patented Ultra Low EMF Nano Carbon Heater
Sunmaxx Sauna heaters are produced using Nano Carbon material from Japan. The heaters are backed with a Lifetime Warranty and have been used in Infrared therapy products for 10 years. They are patented in numerous countries including Germany and Japan and have been tested by several independent laboratories to verify their Infrared output. Test results have confirmed the Nano Carbon’s high Infrared output and desirable therapeutic frequency range.
What are “Carbon Heaters”?
Let me briefly explain infrared heaters first. Different heating elements will make a huge difference to your overall experience and the amount of actual infrared that is absorbed by your body. The heating technologies you come across in New Zealand are ceramic heaters and carbon fibre panel heaters. These can vary considerably in their reliability, total heating area, wavelength and quantity of infrared that is emitted.
Carbon Fibre Panel Heaters vs Ceramic Heaters
Carbon fibre panel is the newest infrared technology available and uses large, flexible and flat carbon fibre panels within the sauna. A carbon fibre heater is an ultra thin carbon ink heating board that is light weight and flexible. It only takes up very little space in your sauna. It also lasts a lot longer than ceramic heaters. Due to the high temperatures of ceramic tubes used by other suppliers they tend to have a higher failure rate and have an approximate lifetime of 10,000 hours or 10 years while the expected lifetime of carbon fibre heaters is 50 years or more.
While both carbon fibre and ceramic heaters produce infrared waves, it is generally accepted that the carbon fibre panels will cause a deeper sweat. This is a significant difference to consider, as a proportion of the sweating caused by the ceramic heaters can be attributed to its shear high temperature, which results in more of a surface level detoxification (i.e. It is generally not desirable to have such high heater temperatures as it is the infrared rays more than the increased temperatures that helps to create a deep-tissue detoxification). The hotter operating temperature of ceramic heaters can result in more breathing difficulties and can cause a burning sensation on the skin and eyes if used for prolonged periods. As mentioned earlier, it also increases the heater failure and can cause damage to the wood. Typically, the technology employed in carbon fibre heaters relies more heavily on producing the infrared at a lower temperature that will be more comfortable when sitting beside.
Studies have shown that the carbon fibre heaters often far surpass the heating surface area of ceramic heaters. A total heating area for a sauna with carbon panel heaters is approximately 6 times larger than a sauna with ceramic heaters. Heat via a large panel as opposed to a thin tube helps provide a much larger surface area for the healing infrared rays. This results in a more even distribution of heat whereas ceramic heaters can lead to uneven heat distribution. The large heating area makes sure that nearly every square inch of your body is heated by the infrared rays.
Our Nano Carbon Heaters
All of our saunas use our revolutionary Ultra Low EMF Nano Carbon Heaters, which have some similarities to other carbon fibre panel heaters on the market but BETTER!
The Nano Carbon heating panel uses a sheet that has been impregnated with carbon using a special high temperature pressing technique to produce a resistance that will emit infrared waves at the optimum wavelength of 9.4μm for the human body. In addition, using this in-house vacuum pressing technique, a higher level of infrared can be attained, that also results in an even, safe, surface temperature that is more comfortable for the user. Furthermore, no unhealthy gasses will be emitted during heating due to its unique manufacturing methods. The Nano Carbon heater used for IYASHI saunas was the first to gain patent approval for using nano-technology to create the far infrared heating board.
The Nano Carbon Heater has been thoroughly tested at the National Taiwan Normal University in the Physics department’s far-infrared lab. These studies have demonstrated that the Nano Carbon Heaters produce far-infrared rays close to perfection to work with the natural harmony of the human body resulting in increased health benefits.
Studies have shown that the body naturally radiates infrared between 2-50 microns with the peak output of the body being around 9.4μm. In fact, NASA states that humans emit infrared most strongly at 10 microns, which provides the perfect body resonance.
The Nano Carbon Heaters output infrared in the far infrared 6-14μm wavelength range, which is perfect for humans. Research findings on the Nano Carbon Heaters have shown that the peak output is evenly spread around the optimum 9.4 microns. This results in a natural resonance that directly relates to the peak 9.4μm output of the human body.
Infrared has a large range on the electromagnetic spectrum so check to find the output range and peak output of the heaters from your comparison sauna suppliers and look for an output that is close to the human bodies peak output. Oftentimes, many products have not been tested making it very difficult to verify their safety and peak infrared output wavelength.
So, what’s EMF?
Electromagnetic fields (EMF) are areas of energy that surround electronic devices. The World Health Organization (WHO) explains that the electric fields are created by differences in voltage and magnetic fields are created when the electric current flows. According to WHO, electromagnetic fields affect us because our human bodies have their own electric and biochemical responses (e.g., nervous system, digestion, brain function, heart function). So exposure to EMFs can interact with your body in adverse ways.
Electromagnetic fields (EMFs) can cause symptoms of illness in infants, children and adults, particularly those who already experience low immunity.
If you are sensitive to EMFs, you may experience symptoms like:
- Nervous system symptoms, like fatigue, stress and sleep disturbances
- Skin symptoms, like facial prickling, burning sensations and rashes
- Body symptoms, like pains and aches in your muscles
- Eye symptoms, such as burning sensations
- Foggy thinking and depression
- A variety of less common symptoms, like ear, nose, and throat symptoms and digestive disorders
- Infertility
- Leukemia in children, breast cancer or cancer clusters have been linked to high exposure to EMFs
The heaters used in most infrared saunas emit high EMF – some websites even recommend avoiding all Far Infrared saunas for this very reason. Well, if you’re thinking about purchasing an infrared sauna for the purpose of improving your health and it is actually causing damage to your health due to its high EMF, what’s the point, really? When I was looking for an infrared sauna, I contacted the companies iregarding the level of EMF their heaters are emitting. Their answers were “it’s within a safe range”… It wasn’t convincing to me at all. All the saunas out there are being sold under the assumption that the EMF level is “within a safe range.”
Our saunas are made in China by a reputable manufacturer, Sunmaxx Technoloy Co., Ltd. and their saunas are sold worldwide. One of the companies who sell the same saunas did a test to compare the EMF levels of different infrared sauna heaters. We measured the EMF level at 2 inches away from our patented Ultra Low EMF Carbon Panel Heater, solid ceramic infrared heater, ceramic tube infrared heater and two other carbon panel heaters out in the market. The results were staggering. (NB: The maximum level of EMF that the equipment they used could measure was 100mG.)
Carbon panel heaters with concentrated carbon are expensive to produce and are used in a few sauna brands like ours. Carbon panel heaters with low density carbon are inexpensive to produce, have lower Infrared output and are found in many Infrared sauna brands.
High Intensity Infrared
The quantity of Infrared that the sauna produces and the quantity that hits your body to warm you in the sauna do matter. Carbon panel heaters on the market are made with different qualities of carbon materials and with different manufacturing processes. There are cheaply made, poor performing heaters and there are high quality, high performing heaters.
The performance of a carbon panel heater is determined primarily by the concentration of energy/electricity in the panel. The more concentrated it is, the higher levels of infrared the panel would produce. The specialized ‘nano’ forms of carbon used in our heaters originate in Japan and very few companies possess the technology to process the carbon and produce high performing carbon heater panels.
Carbon panel heaters with concentrated carbon are expensive to produce and are used in a few sauna brands like ours. Carbon panel heaters with low density carbon are inexpensive to produce, have lower Infrared output and are found in many Infrared sauna brands.Cheap low density carbon panels are easily identified in saunas. They cover much of the inside walls of the sauna and extend high up the sauna walls.
