Types of Sauna Heaters

The three primary types of sauna include – wood, gas, and electric.

We will address each one of these heaters in-depth and their respective pluses and disadvantages.

We have listed, measured, and reviewed 11 of the industry’s best sauna heaters in this report, and each one of them has its own advantages and disadvantages. So, without further ado, scroll down and learn more about sauna heaters in detail.  

Traditional Sauna Heaters (Wood)

This sauna heater is easy to assemble because wood is burned to produce heat for an incredible sauna bath experience. The best thing about it is the scent of the wood, an adamant element in a sauna bath for sauna lovers.

There are high running costs for these home sauna heaters, although they may initially come cheap. Traditional sauna heaters are a perfect option to be kept in those areas where no electricity is found.

Although these heaters are unable to control heat production, the experience is always better than an electric sauna.

Many businesses outfit it with hot water tanks to double the user’s experience.

Gas Sauna Heaters

Gas sauna heaters are perfect for those areas with LP gas or natural gas in abundance.

As they are essentially designed for commercial purposes, they are mainly found in gyms, hotels, and spas.

Their high cost of original, operating, and maintenance makes them not very suitable for home use.

However, these saunas can turn out to be the most cost-effective alternative in commercial areas where 8-12 hours of regular heating is required.

Another big downside is the difficulty of installation and of routine maintenance.

You will need to have a trained technician, especially for its routine repairs to ensure its good condition.

Electric Sauna Heaters

Electric sauna heaters are the ones in high demand on the market, and there is a very compelling explanation for that.

They are inexpensive, easier to run and maintain. Apart from that, this type of heater offers a wide variety of phenomenal features and specifications.

For example, by programming it or controlling it from your mobile, you can skip the sauna’s waiting period to heat up. However, you must invest in a reliable electric sauna heater for this.

For indoor saunas, electric sauna heaters are the most appropriate. All you have to do is plug the switch in and wait to heat up the sauna.

The great downside of this type of sauna is energy consumption. Your electrical bills would significantly increase when using it.

Infrared Sauna Heaters

Infrared sauna heaters have completely different operating modes than the rest of the saunas that are mentioned above. Instead of heating the air around it, they directly heat the body.

Thanks to their reduced operating cost and simple installation, the infrared sauna heaters are rapidly gaining popularity.

Most of the time, the infrared heaters can be found from indoor saunas. It has a more intense performance in a low-temperature range.

And you can also miss waiting for 15-20 minutes until the sauna heats up.

  • Capacity Stone

One way of calculating a sauna heater’s power is to find out the potential of its stone or rock.

To put it in simple words, the stone power means that the sauna heater is capable of heating up a specific equivalent of the weight of the sauna stones.

The more efficient a sauna heater is the higher its capacity.


The cost of sauna heaters primarily depends on their heating ability, the type of heat source, and its body.

The most expensive is gas sauna heaters, while the most economical are electric sauna heaters which are ideal for home uses.

Frequently Asked Questions

How is the ventilation arranged when an electric sauna heater is installed in the sauna?

Traditional or natural ventilation that uses the hot air’s natural flow. An inlet of fresh air under the radiator and an outlet high up on the opposite wall of the ceiling. This gives the floor and the lower benches a decreased temperature. It is usually used with heaters for wood burning, but it can be used for all heaters.

Forced mechanical ventilation is based on the fresh air intake right above the heater or above the heater in the cell. This gives the sauna a more uniform temperature. This ventilation technique cannot be used for Tylo Sense heaters as they contain traditional ventilation.

How to calculate the volume of the sauna when fitting an electric sauna heater?

Multiply the width and length by the height. After that, add the volume of cold surfaces, such as to measure the stone, and the surface of the glass is and then multiply by 1.5. The effect is a cubic meter, which you then add to the sauna’s volume. Pick the performance of a sauna heater according to the outcome.

Which is the best stone for sauna heaters?

You can always get to know about the best stone of the sauna heaters with the help of its manufacturer. For example, Tylo heaters suggest vulcanite mineral, which is ideal for the sauna heater and safe for this stone consistency. Always make sure to go through the instructions before buying the stone for the sauna heater.

Do I need to have stones in my heater?

Most heaters come with an optional characteristic of how many stones are appropriate for that heater. For your chosen heater, please see the technical specifications.

How often should I reset the sauna heater stones in regular use?

For stone resetting, you should adopt these rules.

  • If you use the sauna once a week, reset the stones at least once a year. Similarly, if you use the sauna twice a week, replace the stones twice a year.
  • When rearranging the stones, cracked and sand-surfaced stones are eradicated and substituted by new ones. Hence, it is essential to re-stack the stones regularly to allow the air to flow freely amidst stones.
  • Check the stone compartment at least once a month and replace the stones if necessary.

How frequently should the stones in a sauna be swapped?

This relies heavily on how much the sauna is used. The stones should be swapped at least once a year if it is a private sauna. Good air ventilation is important to make sure the heater works appropriately and improves the life of the heating elements. Apart from that, it is suggested to examine the stone compartment at least once a week or twice a month.

What happens if I pour water on top of the heater?

You can pour water over the stones when your heater is hot enough to improve the sauna’s humidity. The water quantity that you pour each time on the stones will depend somewhat on the heater size. One scoop of water, 15 cl. or so, is perfect. If the water flows out of the heater’s rim, it means you’ve poured too much water, or it doesn’t make the stones hot enough.

What factors should I look for when my heater suddenly stops working?

First of all, check if the circuit breaker has tripped or the fuse of the heaters has blown. If that’s not the reason, the heater could have been switched off by overheat security. Tylö’s sauna heaters come with a temperature regulator at the bottom of the furnace built into the switch case. If there is some danger of overheating, it activates automatically. Always contact a licensed electrician to reset the temperature regulator if you can not reset it outside of the heater.

What are the supposed benefits of infrared saunas?

The supposed benefits of infrared saunas are almost similar to those of traditional saunas. These include:

  • Relaxation
  • Detoxification
  • Relief from sore muscles
  • Clear and tighter skin
  • Weight loss
  • Improved circulation
  • Relief from joint pain such as arthritis
  • Help for people with chronic fatigue syndrome
