Traditional Sauna Benefits

Traditional sauna heaters are one of the most common heaters on the market. They are powered by gas, wood, or electricity. Out of those three the most efficient/durable one is the electric sauna heater. This is the heater that most see in residential saunas at pools and gyms. Majority of these heaters are wall mounted and made with durable steel. They also have teflon coated heating elements that are built to last a few decades.

These types of saunas work by warming sauna rocks that then warm the sauna room by convection. When the rocks are heated the sauna room can reach temperatures as high as 194 degrees F. This whole process takes around 30-45 minutes depending on how powerful the heater is and how small the room is.

Traditional saunas heaters use the most energy compared to other sauna types (such as infrared saunas and portable infrared saunas). This is because of the way they heat the sauna and the temperatures they can reach. Since this is so, most residential heaters operate on 220-240 Volts. This requires the same outlet you would use for a drier. Other smaller home units run off of 110 Volts, which can run off a traditional outlet. Just keep in mind that the higher the wattage, the faster the room will heat up.

These traditional sauna heaters promote settings of dry, very hot, and relaxing environments. Since they use heating elements you can pour water on the rocks to produce steam. This is a plus as it offers many respiratory benefits that other saunas don’t provide. Other benefits that these sauna heaters promote are increased cardiovascular health, weight loss, detoxification of your body, they cleanse your skin, they promote better sleep, boost your immune system, and many more.

Overall these types of saunas are perfect for those looking for a traditional sauna that is going to last decades. Just remember that even though these heaters can be expensive, that they are a wise investment as they improve your health and boost your home’s value.
