Heating Your Sauna: A Guide to Different Methods

When setting up a sauna, the way it’s heated makes all the difference. Traditional saunas use a fire under rocks to create moist, therapeutic heat. This method, dating back centuries, involves heating stones with fire and then letting the residual heat from the embers warm the space. Modern advancements introduced the electric sauna heater, making the process more convenient by warming air and stones with the flick of a switch. In the last 20 years, infrared saunas have changed the game by using infrared wavelengths to heat the body directly, offering a dry heat experience that’s different from the moist warmth of conventional saunas. Choosing between wood-fired, gas, electric, or infrared heating depends on your personal preference, the sauna location, and the type of warmth you find most relaxing.

Each method, from the traditional to the infrared, offers a unique sauna experience. Whether you’re drawn to the rustic charm of a wood-fired sauna, the ease of an electric model, or the gentle warmth of infrared, understanding these heating methods is crucial for building the sauna that best suits your needs.

Wood-Fired Saunas: The Classic Way

Wood-fired saunas are the true, old-school way to enjoy a sauna. They use a traditional wood-burning stove, made of steel or cast-iron, that burns wood. This heat from the fire goes to a basket of rocks on the top of the stove. These rocks warm up evenly and make the sauna feel nice and soft. To add moisture to the air, you sprinkle water on the hot rocks. This makes steam and raises the overall temperature in the sauna. It’s a classic way to heat a sauna and many people love it for its simplicity and the cozy feeling it gives.

Electric Sauna Heater: A Modern Choice

The electric sauna heater is now the most common way to heat a sauna. It’s said that 95% of saunas use electric heaters instead of a wood-fired stove. These heaters work a bit like a baseboard heater but warm a basket of rocks to raise the ambient temperature inside the sauna. They often need 20-, 30-, or 40-amp dedicated circuits in your home, and many models come with control modules that can be built into a wall-mounted unit. This makes them a popular choice for indoor use because they are clean and cheap to run.

The elements in the heater heat the stones, which are placed on top to radiate a gentle heat. When water is splashed on these hot stones, it creates löyly, which is the steam that increases humidity and enhances the sauna experience. One big advantage of these heaters is that they are thermostatically controlled, making them easier to set to a temperature that suits you. They come in either free-standing or wall-mounted options, with a range of sizes to match the amount of heat they give out. For an average family sauna, a 6Kw stove is typical, but manufacturers will provide details to help you choose the correct size for your needs.

Infrared Sauna Heater: A Newer Technology

The Infrared Sauna Heater is a newer approach to sauna heating technology that has been gaining steam (pun intended) in recent years. Unlike traditional methods that heat the air around the user, infrared heaters warm the body directly. They do this with light frequencies, a type of electromagnetic radiation, which means the air stays cooler while the body heats up.

Infrared saunas produce less heat than other saunas, usually staying right around 140 degrees. This makes them a great option to be retrofitted into areas as small as a closet space. They use special modular lighting panels that emit infrared light, providing a gentle, direct warmth that many find soothing and beneficial for health.

Gas Sauna Heater: Efficient and Fast Heating

Gas saunas use natural gas or propane as their heat source. They are typically larger than both wood and electric saunas and tend to cost more upfront. However, they require less maintenance in the long term and are cheaper to operate. One of the main benefits of gas heaters is that they heat up faster than other types of sauna heaters, making them a convenient option for those who want to enjoy their sauna without a long wait.

The Sauna Stove: A Touch of Tradition

Sauna stoves bring a traditional feeling to the sauna experience. You heat the stove with logs, and rocks sit on the top. This method is used almost exclusively in outdoor cabins, bringing users closer to the original concept of sauna with very little maintenance. Just check the chimney and flue to keep them clean and unrestricted. The cost of running a sauna stove is dependant on wood. If you’re lucky enough to chop your own wood, the cost comes down to zero. Birch logs are traditionally the choice for firewood, essentially because of their high heat output and pleasant aroma. When water is splashed on the stones, it vaporises on contact, helping bathers sweat in a humid atmosphere. This process, known as löyly, enhances the sauna experience by increasing the humidity and heat through the evaporation of water.

Tips to Increase Sauna Temperature

Heating a sauna to the right temperature makes the experience best. Some ways to increase the temperature are simple yet effective. Here is how you can make your sauna hotter.

First, to get more heat, discover how to tweak the settings. Most saunas let you tweak the temperature to your liking. This is a straightforward and powerful method. It lets you control how much heat you want.

Using these techniques, you can enjoy your sauna sessions more. Everyone has their own liking for how hot they want their sauna. With a bit of adjustment, you can find the perfect setting for you.

Remember, the key to a good sauna experience is to adjust and find what works best for you. These tips are from my own experience. They have helped me and many others enjoy our sauna sessions more.

Inspect Power Output

To heat a sauna, it is essential to consider the heater’s appropriate power output. The size of your sauna room, its volume, ventilation, insulation, and the presence of windows all contribute to determining the required power for your heater. To increase sauna temperature effectively, the heater must have adequate specifications to heat the space.

Adjust the Settings

For the best sauna sessions, placing the heater five to seven inches off the floor is recommended. This setup helps achieve even heat distribution in the room. As warm air rises, cooler air replaces it, creating a convection current. With the heater closer to the floor, rising warm air can spread more evenly across the room, reaching the ceiling and making the sauna hotter.

Investigate the Thermostat

To ensure your sauna’s thermostat is functioning correctly, follow these guidelines:

  • Position the thermostat sensor one to two feet from the heater to avoid direct heat influence.
  • Place the sensor approximately one inch from the ceiling to capture the warmest air in the sauna.
  • Recalibrate the thermostat if necessary, following the manufacturer’s instructions. If recalibration doesn’t resolve the issues, consider replacing the thermostat with a compatible model.

Maintaining the correct position and calibration of your sauna thermostat ensures accurate temperature control, providing a safe and enjoyable sauna experience.

Add Insulation

Insulating your sauna walls helps prevent heat from escaping, a key factor in learning how to get your sauna hotter. Insulating the walls, ceiling, and door with appropriate materials like mineral wool or ceramic fiber helps prevent heat from escaping. Sealing any gaps or cracks around windows can further improve insulation. With adequate insulation, your sauna is better equipped to maintain a higher temperature, allowing you to enjoy a more intense, invigorating sauna experience.

Preheat the Sauna

Preheat the sauna for 30 to 45 minutes for traditional saunas or 10 to 15 for infrared to ensure the rocks are thoroughly heated. This is essential for a comfortable and hot environment. Retain heat and allow the temperature to rise to the desired level for a subpar experience. In wood-burning saunas, add wood to the stove, choosing birch for effective heating over pine wood.

Increase Humidity

Increasing humidity directly affects how hot the sauna feels and hampers sweat evaporation, which cools the body. Add water to the rocks to increase moisture in the air, slowing the cooling process and making the temperature seem higher.

Exercise Beforehand

Engaging in physical activity before entering the sauna can raise your body temperature. Keep the session short to avoid dehydration and excessive sweating.

Adjust Vents

Open the vents as the sauna heats up to avoid triggering the high-limit sensor too early. Close them to retain heat. If it gets stuffy, briefly open them for fresh air.

Pick the Right Stones

Replace your sauna stones with dark-colored, medium-sized, rough texture stones with no cracks. Rinse and combine medium and small stones to fill gaps for adequate airflow. Suitable rocks like Vulcanite, Olivine-diabase, Peridotite, Olivine, and Ceramic volcanic can withstand high temperatures and efficiently retain heat, creating a comfortable, enjoyable environment. Avoid random rocks from rivers or your backyard, as they are a safety hazard; river rocks can trap water, and when heated, may crack or explode, becoming dangerous.

Maintenance and Cleaning

Regular cleaning and maintenance are vital for optimal sauna performance. Over time, dust, debris, and mineral deposits can accumulate, affecting the sauna’s heating capabilities. This ensures a more intense and satisfying sauna experience.

By understanding these simple yet effective tips and techniques, you can tweak your sauna’s temperature to your liking. It’s straightforward and powerful to discover how to increase the temperature and enjoy your sauna sessions to the fullest. Always ensure your sauna’s heater has the appropriate power output for the size and volume of your sauna room, considering ventilation, insulation, and the presence of windows to heat your space effectively.
