Best Sauna Heaters Types

Did you know that there are different kinds of sauna heaters? They use different sources of heat. Different sauna heaters also give different kinds of experience. The setup from one to the next would be different too.

One of the first things you should decide on shopping for the best sauna heaters is deciding what type of sauna heater you want to use.

Wood sauna heater

If you want to stick to traditional sauna heating methods, you can get an authentic sauna experience with a wood burning sauna heater. It is excellent for houses that have a charming, rustic feel.

For this type of sauna heater, wood is placed in an enclosed steel frame where it burns to generate heat for your sauna. The best thing about using a wood-fired sauna heater is the aroma, a great ambiance booster.

Wood home sauna heaters are affordable. However, operating this type of sauna heater takes up more work and effort than how the other types operate. They are best for outdoor saunas. In fact, this type of sauna heater is the only option for areas that do not have access to electricity,

Electric sauna heaters

For those who lack the time and dedication required to maintain traditional sauna stoves, an electric sauna heater is the best option for you. They are the most common type of sauna heater that you can find in the market.

Electric home sauna heaters are affordable, easy to use, and easy to maintain. They also come with a lot of features. The only major drawback is that they can eat up a lot of power, which could impact your usual energy bills.

This type of heater is best for indoor saunas.

Gas sauna heater

This is the type of sauna heater being used in most spas, gyms, and hotels.

You have to know that this type of sauna heater is mostly expensive because they are made for commercial purposes. They have a high initial, maintenance, and operational cost. The installation process is also known to be very complicated and should be left to the professionals.

The gas sauna heater is best for areas that have an abundance of natural or LP gas. This is best if you plan to do a business out of it, but it could be a poor choice for home saunas.

Infrared sauna heater

The infrared sauna heater, also known as the far-infrared (FIR) sauna heater, is a new industry development. You may find that some significant sauna societies have not recognized them yet.

Despite being new, infrared saunas have been trending as they claim to give the most health benefits among the sauna types we have on the list since this type of sauna heater does not use steam.

However, maintenance and repair could be expensive. If you choose an infrared sauna, you need to take good care of it all the time. You should also know that infrared sauna heaters are only suitable for dry sauna setups and indoor infrared saunas.

There are cheaper and portable versions of an infrared sauna that are also easy to use. These infrared sauna heaters allow you to enjoy the sauna experience without having a dedicated sauna room. However, they often can be tacky and weird looking.

Best sauna heater buying guide

Do you now have your pick from the recommended sauna heaters above? Before you make a purchase, check out this buying guide to ensure that you pick out the best sauna heater for your needs.

Factors to consider

Here is a list of factors that you should consider before buying a sauna heater


You should consider two sizes: the size of the sauna heater itself and the size of your sauna room. Sauna heaters must be a good fit so that they do not not ruin the design and ambiance.

Check the product specifications for the recommended room size. If your sauna room is bigger than the number, the product is too weak for your needs.


For something that deals with heat, quality should be the first and foremost feature that you should look into when shopping for the best sauna heaters in the market. Try to get sauna heaters that are made out of stainless steel. This is one of the strongest and most durable materials. Stainless steel is also rust-resistant, which is essential since sauna heaters are exposed to moisture, water, and humidity.

Heating time

It’s a fast-paced world, so it is no wonder that people would not want to waste time waiting for their sauna room to heat up.

Although there are sauna heaters that can heat up a room instantly, they are actually not recommended if you want a unit that will last for a long time. You see, the faster the sauna heater fires up, the less durable the sauna heater will be.

It is safer to stick with sauna heaters that will take time to heat up since they are usually made out of materials that can handle more temperature inertia. These type of sauna heaters also end up keeping the room hotter for a longer time.


Do you plan to install the sauna heater yourself? Then you should consider how a product is installed. Are the instructions clear enough? Is it a simple installation? A product with an easy install is best for those who love to DIY their home projects.

But if you really want a particular product but could not deal with the complexity of the setup – you should not let that hinder you from getting the best sauna heater. You can always hire a professional to do the installation for you.

Stone capacity

This identifies how much sauna stones the heating unit can handle. The higher the stone capacity, the more powerful the unit is.


People do not think much about this, but the type of controller your sauna heater has can make or break your sauna experience.

You can find a lot of sauna heaters with controls on the bottom. This is relatively fine, but if you are dealing with a cheap product without heat protection, they can get very hot by the time you want to turn off the sauna heater and could burn you.

To be on the safe side, try to get sauna heaters that have external controllers too so that you do not have to go near the sauna heater itself when you need to make some adjustments.


Of course, you have to consider your budget. The cost of a sauna heater mainly depends on its heating source, capacity, and features.

Gas sauna heaters are considered to be the most expensive because they are mainly produced for commercial use.

Electric sauna heaters are the most common and most affordable for private saunas at home.

Wood sauna heaters do come with an affordable price, too, but they also have a high operational cost.


When it comes to major purchases like sauna heaters, a warranty is an essential factor. Warranties are a big help when you have to repair your sauna heater later on.

All manufacturing companies that offer premium sauna heaters give warranties with their products. The usual warranty period that you can get is at least 2 years.


Remember, sauna rooms will only be as good as the sauna heater that is being used. To make the most out of your spa room, you should invest in a good sauna heater to boost its capacity to help you rest and relax.
