What is the difference between the Ceramic Heaters and the Carbon Heaters?
Both heaters will provide the same health benefits and will do the same job. However, the heat distribution differs between the two heaters. If you are interested in using the sauna for a quick intense sweat, ceramic would be the best choice. Carbon is favored as the heat is more comfortable and makes it easier to relax in the sauna longer and will still provide an intense sweat. Carbon heaters are also more commonly used for those with a condition or disease in which the infrared can improve health and well-being.
Ceramic Heaters
- Have a high emissivity (degree at which material can emit)
- On average lasts about 9,000 hours
- Rod shaped for optimum FIR dispersement
- Made of true ceramic
- Does not have a large surface area but because they are enclosed in a reflective plate the far infrared is able to target a large portion of the body
- Ceramic heaters have the fastest warm up time to produce a very intense heat that will allow you to sweat within minutes
Carbon Heaters
- Have a high emissivity (degree at which material can emit)
- On average lasts about 18,000 hours
- Made of a thin carbon plate for even heat and FIR emmission
- Flexible and less fragile
- Flat surface allows for a more even heat distribution
- Largest flat surface area that infrared heaters offer
- Low wattage carbon heaters give off a more gentle, therapeutic heat
- Same health benefits as ceramic
What is the difference between Hemlock and Cedar?
The wood of the sauna does not add or remove from the saunas efficiency. The choice of the wood is merely for cosmetic reasons. It all depends on what you would like to see every time you see your sauna. If you have any alergic reactions to certain woods, you would want to choose a hemlock wood sauna. Cedar wood does have a natural pleasent smell which may affect a small number of people in the world. Most steam saunas are made from cedar wood for the reason that bacteria will not grow on the cedar, making it a great choice for a sauna.
Hemlock Wood Saunas

- Non-allergenic
- Non-toxic
Cedar Wood Saunas

What kind of output do the heaters provide?
Within this wide spread of frequencies, the 5.6-15µ range is the most therapeutic to the human body, split evenly between the 9.4µ pivot point of peak human output. The Infrared elements are designed to operate within this range to maximize the effectiveness of your therapy. These wavelengths can penetrate the body's tissues to a depth of 1.5 to 3 inches. Due to the deep penetration of infrared rays, a heating effect is observed deep in the muscular tissues and even into the internal organs, meaning you perspire far more than you do in a traditional sauna.
Hard to reach impurities are eliminated through your skin using lower, comfortable temperatures.
Far Infrared Emissions are up to 96% on both carbon and ceramic saunas.
What is the difference between our saunas and more expensive saunas?
There are alot of saunas on the market that claim to be more than they actually are. Many are over priced and make wild claims about their heaters being superior. The fact is that all the heaters are basically the same with all sauna manufacturers. The reason you see the same basic type saunas for thousands of dollars more than the ones listed on this website is simple; the company does not buy direct from the factory. Sometimes there are 2 or 3 companies in the middle marking up the product to such as higher price. We cut all of that away to bring you the best bottom dollar price.
We are all familiar with the phrase "you get what you paid for!" Well that is not the case with our Precision Therapy Saunas. Precision Therapy is one of the oldest manufacturers of far infrared saunas. They pride themselves on quality workmanship at a reasonable price to the end consumer. The fact that we deal directly with the manufacturer, instead of going through a middleman and we purchase our saunas in larger quantities, allows us to pay less. We are able to pass the savings on to you, our customer.
We want you to get the best quality product at the lowest price available and without all the hassle.
Since we do not sell the same saunas as our competitors we cannot speak on their behalf, but we can tell you that our saunas are top quality. The parts and components of our saunas are put through the toughest tests to ensure quality.
We offer the best technical team around that will work with you if you ever have the rare occasion of your sauna malfunctioning. We are open 7 days a week from 8am - 9pm EST Mon-Fri and from 9am - 5pm Sat-Sun. We have 3 sauna technicians on staff to troubleshoot and resolve all of your technical problems. Not many other sauna companies can offer that service.
