How Electric Infrared Heaters Work?

Maybe you have chose to build an infrared sauna in your house or office, and you are now wondering about the various electric infrared heaters available to you. Or you are just interested in how infrared heaters work. Whatever the reason for wanting to know more, this information is an ideal source for infrared heating unit information.

Infrared heaters are composed of thin, flat sheets or plates. It is imperative with infrared radiation that the large surface area is covered. The widest, tallest infrared heaters will normally be the best at doing their jobs and effectively emitting the infrared radiation the sauna needs. Some infrared heater manufacturers make infrared heaters which come in the form of incoloy rods, but these will not be effective or efficient because of the small area that they cover.

Most infrared heaters are made from carbon fiber, but there are ceramic and steel heaters too. There are numerous claims available about what material is best for a heater, but one sure way to know how one heater compares against these guys researching its emissivity. Emissivity may be the way of measuring an object’s ability to emit far infrared radiation. It ranges from 0 to some perfect blackbody 1.0. Ceramic heaters have the highest emissivity value, meaning that they are best able to emit far infrared radiation. Considering the light spectrum can have that there is both infrared radiation and far infrared radiation. Though any of the standard materials will heat the sauna, the health benefits of infrared will be most pronounced with ceramic heaters.

Placement of the heating elements in an infrared sauna can also be an influential factor in how well they work. Infrared saunas require multiple heaters so they are emitting radiation evenly all throughout the sauna. One disadvantage to infrared radiation is it doesn’t travel very far, so the heaters have to be placed relatively close to users. At the minimum, the sauna room will need an appropriate number of heaters for its area. Sauna users should be absorbing the light from all around them, such as the back and the front.

Something to know is the fact that infrared heaters work differently than traditional saunas. Traditional saunas are heated using a box filled with hot coals or rocks that heat up the sauna room. Heating elements reach surface temperatures as high as 180 to 220 degrees F. They often require 30 to 1 hour 30 minutes of warm-up before they are fully hot and working at peak efficiency. Infrared heaters, however, really are a revolutionary method to power a sauna. They emit infrared radiation, that is an invisible type of light around the light spectrum. It directly heats objects, not requiring the air to obtain hot to be able to work.

By eliminating the necessity to heat the air and just directly warming the people within the sauna, infrared heaters are able to work quicker, more efficiently, and at lower surface temperatures than traditional heating elements. Infrared heaters usually measure between 110 and 140 degrees F while operating, and only require typically 20 minutes of warm-up before they’re ready to use. Their low surface temperature makes them more energy-efficient (and therefore, cost-effective) to use by 30% to 50%.

There are several major differences between traditional sauna heating elements and electric infrared heaters. Infrared saunas work in an entirely different way, therefore it stands to reason the heaters do too. Their construction, area, and site in the sauna all really make a difference in their ability to work well.
