If You’re in a Hurry – My Top Picks at a Glance
How Does an Electric Sauna Heater Work?
Electric sauna heaters are the most widely used type of heater, so they’re the ones that people are most familiar with. Gas, wood, and electric sauna heaters all heat the space using convection. With an electric heater, the electricity is transferred through resistive elements to generate heat.
The resistance means the electric energy is converted to heat energy, resulting in the elements heating up. The heat is transferred from the heating elements to the sauna stones that are placed on top of them. These sauna stones retain heat and are responsible for heating the surrounding air.
Thanks to the direct contact between the sauna stones and the heating elements, the heat is efficiently transferred. When the sauna stones get hot, water is slowly added which immediately evaporates, creating steam. This is then circulated around the sauna, creating that coveted hot and humid environment.
Compared to a gas or far-infrared sauna heater, electric sauna heaters don’t respond to thermostat adjustments because of how long it takes for the heating elements to heat up and cool down.
However, this isn’t a problem in saunas as precise regulation of the temperature isn’t required, unlike in an appliance such as an oven.
How do Other Heater Types Compare?
Next, let’s look at how other types of sauna heaters compare to electric ones. We’ll take a look at the pros and cons of gas, wood-fired, and infrared sauna heaters.
Infrared heaters are great for home saunas as the temperature range can be controlled easily. They create a comfortable environment for the user as infrared technology targets the body directly, rather than heating the surrounding air.
They’re also cheaper to run and maintain, are very eco-friendly, and are easy to operate. With that said, they are more expensive to set up, meaning they may not be great for commercial use.
Next, we have gas sauna heaters. Similar to wood-fire sauna heaters, gas heaters are ideal if you have limited electricity or none at all, but you have LP or natural gas available. Because of their higher price tags and the fact that there aren’t many gas sauna stove manufacturers in the US, gas heaters aren’t usually the first choice for home sauna owners.
Just like wood-burning sauna heaters, gas heaters aren’t made for small sauna setups. This is not only because they’re expensive, but because they need a gas plumber or AC technician to make sure that the venting and gas lines are installed correctly.
They’re more commonly used in large commercial sauna rooms, such as hotels, gyms, and spa centers. In these establishments, it’s common for the saunas to be in demand 12-24 hours a day. Because of this, gas sauna heaters are often the most reliable choice.
Gas heaters also need regular maintenance which can work out very expensive. They aren’t very eco-friendly, especially if you’re using petroleum-based gas and they can be a little bit more complicated to operate than wood or electric sauna heaters.
For traditionalists, wood-fired sauna heaters are a great choice. Lots of long-time sauna owners and users prefer the smell of wood smoke because it reminds them of early memories of using a sauna. These typically work best in larger saunas, as the heat they generate can be a little tricky to regulate.
Wood-fired sauna heaters are very popular with outdoor sauna owners. They’re also suitable for cabins or in locations where there’s no available electricity. Many of them include optional water tanks too, making your sauna heater more versatile.
Recently, living off the grid has made a comeback and this has made people rediscover the joy of wood-fired sauna heaters.
A wood-fired heater is relatively cheap for its size, but it’s essential to take the shipping costs into account. Most wood sauna heaters will come with a hefty amount of sauna rocks, usually around 150 pounds!

Sauna Heater Buying Guide
Now that we’ve looked at the best sauna heaters on the market, let’s take a look at what you’ll need to think about before you rush to buy one. There is more to buying a sauna heater than you probably think, but it doesn’t have to be a frustrating task.
Read on to find out about some important factors to consider before buying one!
Probably the most important factor to think about is the cost of your new sauna heater. It’s easy to get carried away and spend a fortune on a heater that is out of your budget. The sauna heater cost will mainly depend on its heating capacity and the type of heat source it uses.
Gas and infrared sauna heaters typically come with the highest price tags whereas an electric sauna heater would be affordable for a home sauna.
A wood-burning sauna heater may be cheap initially but its running costs can be very high unless you can collect wood yourself – in which case it would be a very cheap option! Ultimately, an electric sauna heater is the most cost-effective option for home sauna setups and even commercial ones.
To prevent overspending, set a budget before you decide on your final purchase. This avoids procrastination and viewing products that are too expensive!
Be sure to pay attention to how many cubic feet of space the electric sauna stove can cope with. Compare this with how big your sauna is and you’ll have a good idea of the size of the heater you’ll need.
To work out the volume of your home sauna room, use the formula length x width x height. Work out the square footage of your floor and multiply it by how tall your sauna is. This will give you the total size of your sauna in cubic feet.
It’s a good idea to choose a heater that can cope with a sauna room bigger than yours, as this will ensure it can get hot enough without it working on full blast continuously.
Next, pay attention to how easy the sauna heater is to operate. These days most sauna heaters are fairly uncomplicated to navigate. Some have mechanical knobs that have to be manually adjusted, while some will come complete with a digital controller.
Think about what is easier for you and what you prefer. If you don’t want to keep getting up to adjust the timing and temperature, be sure to choose a model that has a digital controller.
Electric sauna heaters are usually programmable and some of them can be connected to your smartphone, making them even easier to use. Ultimately, the best sauna heater will be straightforward to use, so be sure to check the controls before you make your final purchase.
The stone capacity determines how powerful your sauna stove is. It means that the sauna heater can heat a certain weight of sauna stone materials, whether that’s rocks or stones. The higher the stone capacity number, the more power your stove will have!
Another benefit to having a sauna heater with a higher stone capacity is the steam quality. A heater with a high stone capacity will produce softer and more pleasant steam, giving you a better and more relaxing sauna time.
Like most sauna users, you probably want your sauna stove to heat up as quickly as possible. The best sauna heater will be capable of going from zero to full blast quicker than their less powerful counterparts.
But remember that the faster your sauna heater fires up, the weaker the heat will be. Electric heaters that take longer to heat up will be made with materials that have more thermal inertia. This means the heater will stay hotter for longer.
If you don’t know if the sauna heater is fast or slow, or if it’s working properly, be sure to measure it with a thermometer.
Easy to install?
Last, but not least, consider how easy or difficult the initial installation of the sauna heater is. Do you want to be able to install it by yourself? If so, be sure to look for one that is easy to assemble.
However, if you’d like to have a professional fit your heater, then the complexity of the installation shouldn’t matter. This is probably the best option for electric heaters as they need to be connected to your electricity. Since you may be pouring water onto the heater, it must be safe!
Our pick of the best sauna heater overall is the Finlandia FLB-60 Sauna heater. When it comes to sauna heaters, you can’t go wrong with a model from Finlandia.
Manufactured in Finland, the FLB-60 model is small but very powerful and for complete convenience, it comes with a sauna rock collection for lasting heat.
It’s been designed by following the techniques found in traditional saunas but it boasts modern and state-of-the-art materials, including a stylish stainless steel body. Those who want an easy-to-use sauna stove will be pleased to know it has simple controls that let you preset future starting times.
This means you could come home from a long day’s work and have the sauna ready to go for a relaxing and peaceful unwinding session!
If you have a home sauna, you’re probably going to want an affordable heater. Our best sauna heater pick, the Finlandia FLB-60 Sauna stove is not only affordable but very functional as well.
With its tough stainless steel exterior and ability to heat up to 300 cubic feet, it would be a great addition to any home sauna. However, if you’re really trying to tighten the purse strings, our best budget pick, the Vevor 2kw sauna stove would be an excellent option.
Perfect for dry sauna users, the Vevor sauna stove has a strong 430 stainless steel shell and is capable of heating up to 106 cubic feet of space. It can also be wall-mounted, which will prove to be incredibly useful for those with limited space!
When choosing the best sauna heater for your setup, it’s important to buy one that’s powerful enough for the size you have. Sauna heaters are all designed for different sauna sizes and if you choose one that’s too small, it won’t be able to sufficiently heat your sauna.
On the other hand, if you buy one that’s too powerful, you may have difficulty maintaining the humidity and temperature at comfortable levels. Not only that but it may cause your electricity bills to be much higher than you expected.
Remember that in cold climates or for outdoor saunas, a bigger sauna heater may be needed. Kilowatts are used to measure how powerful a heater is, and most manufacturers will provide information on the number of cubic feet that each one is capable of heating.
As well as kilowatts, it’s important to pay attention to the voltage levels of the sauna heater. Typically, they’ll either be 220v or 110v. If the heater is 110v, it won’t be as powerful and it’ll simply plug into a regular electric outlet and you won’t need an electrician or any special wiring.
On the other hand, 220v heaters are much more powerful and can heat larger spaces. But you’ll most likely need a professional to fit it and wire it for you, which can work out to be expensive.
Electric heaters are the most common these days and they’re great because the heat inside can be easily maintained. They’re also cheap to run, making them excellent choices for home sauna setups.
If you’re new to using a sauna, an electric heater is a great option as it’s easy to use and doesn’t require much setting up. They’re better for indoor saunas and they require very little manual effort to operate!
Gas sauna heaters are much less common but are usually cheaper than electric units. But are gas sauna heaters safe? Gas creates fumes when it burns, so your gas heater would need to have a flue to clear these exhaust fumes outside.
As well as this, the heater would need to have an external air intake, separate from the main ventilation system of the sauna. Because gas is highly volatile, you’ll need a qualified gas fitter to install and connect the heater to your gas supply.
Ultimately, electric heaters are easier to come by, are safer, and are much easier to install than gas units.
