To get the most out of your sauna, you need a good heater. A sauna heater is what determines the temperature of your sauna room and is essential to ensuring a relaxing experience. Choosing the wrong sauna heater could mean you end up spending a lot of money and time on maintenance and unable to achieve your desired temperature.

To help you find the best sauna heater, we have put together this definitive guide. We will talk you through the best sauna heaters, from our top pick, the Finlandia FLB-60, which features a heating area of 300 cubic feet, to the best budget options, as well as what to look for in a heater.

If You’re in a Hurry – My Top Picks at a Glance

Types of Sauna Heaters

Wood-burning Sauna Heaters

Wood-burning sauna heaters are the most traditional heating method used in sauna rooms. A wood-burner heater is a relatively inexpensive way to heat a sauna, and it provides an ambiance that other heaters fail to.

Wood-burning heaters can also be used in wet and dry saunas, making them very versatile. They are powerful and have a high heating capacity, which means they are suitable for very large sauna rooms as well as smaller domestic spaces.

Wood-burning heaters are best suited to spaces where electricity is not available or is limited, as they work by using logs, sauna stones, and water to produce steam. Burning wood is not environmentally friendly because of the amount of firewood that is used, and the CO2 it produces.

Infrared Sauna Heaters

An infrared sauna heater is a popular choice for home saunas because it is cheap to maintain and control and the temperature is easy to control. An infrared heater works by heating our bodies rather than the environment, so you do not get uncomfortably warm as you may do with other sauna heaters.

The initial installation costs and any necessary repairs can be very expensive, however, so bear this in mind. Some studies have suggested that an infrared heater in your sauna brings with it many health benefits. For example, it can reduce signs of aging, boost metabolism, fight illness, and much more.

Electric Sauna Heaters

An electric sauna heater is a more convenient and easier alternative to a traditional wood-burning sauna heater. Most electric sauna heaters are made with stainless steel and use heating coils. Depending on your budget, you can customize your heater with all kinds of additional features, such as digital controls and ambient lighting.

While an electric sauna stove is more expensive upfront than a wood heater, the maintenance and operations work out cheap. What’s more, electric sauna heaters are very eco-friendly, meaning you can use them as often as you want without having to worry about the environment!

Gas Sauna Heaters

A gas sauna heater is often used by commercial sauna rooms that need to heat up large spaces quickly. These types of heaters can run for a very long time and have a high-temperature range, making them ideal for steam saunas.

Gas sauna heaters require a lot of money and effort to run, so are not used often in domestic settings. The day-to-day operation is quite technical, and often requires the help of a professional. In addition to this, investing in gas can be very costly, and petroleum gas is bad for the environment.

Gas heaters, therefore, are not used as often as other heaters are, and are only typically found on business premises.

Sauna Heater Buying Guide


The size of your heater will depend on the size and capacity of your sauna room. If your room is spacious and big, then you will need a large heater to reach all four corners of it. Generally speaking, 50 cubic feet will require 1 kilowatt of power.


Controls are a very important additional feature to many looking to invest in a heater for their sauna room. They make using your sauna heater much easier and more convenient. Controls will either be built into the heater itself or come separately as a remote and dictate things like timing and temperature.

With many modern electric heaters, you can preset the heating elements to turn on at a particular time, so you do not have to wait around for the sauna room to warm up. The best sauna heaters will also come with a digital display, so you can see precisely what settings you are changing.

Stone Capacity

Stone capacity is a way to measure how powerful a sauna heater is. The stone capacity of a heater means its capability of heating a weight equivalent to sauna stones. If a heater has a high capacity, this means it is powerful.

Heat-Up Time

Different types of heaters take different amounts of time to heat up. If you need a large space heating very quickly, then we advise opting for a gas heater or electric heater, as these have fast heating time and designed for commercial use.

Wood heaters take the longest time to heat up, with an hour-long wait time being typical. They are also the hardest to maintain once operating. However, many find the extra effort and time worth it because of the authentic sauna experience that they provide.

Electric heaters are perhaps the most convenient as they can be set on a timer. For example, if you know you want to use your home sauna at 8 pm, you can set this on the sauna heater so that it is warmed up and ready for you by this time.

Easy to install?

Before purchasing a sauna heater, consider whether you will be installing it yourself or hiring a professional. if you have decided on the latter, then you need a heater that is easy to set up, such as a wood heater. A gas or infrared sauna heater would be less suitable, as the upfront installation and maintenance can be difficult.

If you are planning on getting somebody with experience to install it for you, then you do not need to think about how technical the set-up is. However, you may want to think about how easy repairs and maintenance will be.

The sauna heater cost is one of the most important considerations you will make. How much a sauna heater costs depends on its size and its heating capacity. A gas heater, for example, is the most expensive because it is used for commercial purposes.

An electric sauna heater, on the other hand, is the least expensive domestic option but can cost a lot to get installed. Wood heaters are also inexpensive but have higher running costs than electric sauna heaters do.


What is the best sauna heater?

The best sauna heater will depend on your personal preferences, the size of your sauna space, and the type of sauna heater you want. The best sauna heaters should have a power output of 6KW or more, be able to heat up your space efficiently, and have some kind of control panel so that you can adjust the timings and temperature.

Based on our research, we can say that the overall best sauna heater is the Finlandia FLB-60. Finlandia sauna heaters combine the authenticity of a traditional sauna session with all the mod-cons that one would expect from an electric or infrared sauna stove.

Which sauna heater type is right for me?

The type of sauna heater that you go for will depend on your budget, the size of your sauna room, the heating capacity, and the additional features you need.

If you are buying a sauna heater for your home sauna, then we recommend opting for an electric sauna heater. These are typically designed for domestic use and do not cost a lot to run. In addition to this,

How much are sauna heaters?

A sauna stove can cost anywhere between $100 and $1500. The price of your heater will depend on a variety of factors, including its power output, its additional features, its heat-up time, and much more.

Electric and infrared sauna heaters are relatively inexpensive to maintain, but the upfront installation cost can be very high. On the other hand, a gas or wood burner sauna stove can be cheaper to install but more expensive to run on a day-to-day basis. This is because you have to top up gas and firewood much faster.

Our guide has included the best sauna heater for those shopping on a budget, as well as more premium options as well.

What is the difference between an electric sauna heater and an infrared sauna heater?

An infrared sauna heater uses electricity just like its electric counterpart does, but this is where the similarities end. An electric heater warms up the air around you in order to warm up your body, whereas an infrared heater warms up the body from the inside at a lower temperature.
