Types of sauna heaters
A variety of sauna heaters are now available on the market. Your first step in choosing a heater is to decide on what fuel type you would like to use. Sauna's are sometimes heated by gas or oil heaters, although the most common fuel sources are wood and electricity. Electric heaters are most often left on for the whole duration of the sauna bath.
In most cases, atop the sauna heater is a layer or multiple layers of stones. The stones are heated by the heater and are more able to retain heat and keep the sauna hot. The stones are also where water is splashed in order to create the steam for a steam sauna. The addition of steam to a sauna increases the feel of heat as a higher humidity will feel hotter than a lower humidity. Water also transfers heat much better than air so you will notice a sudden difference in temperature when adding water to the stones.
Infrared sauna heaters
Infrared sauna heaters work on a completely different principle than traditional sauna heaters. Instead of heating rocks and the air in the sauna, infrared sauna heaters use infrared light to heat the objects in the sauna, including the people. This allows for a much lower air temperature in the sauna, with the same feeling of warmth and same sweat inducing heat.
