Types of Sauna Heaters
Sauna heaters come primarily in three main types: electric, gas and wood.
Another type, infrared sauna heaters, though in trend these days is not recognized by major sauna societies including the Finnish societies—the birthplace of sauna.
We will discuss each one of these heaters in detail and their respective pluses and drawbacks –
1. Traditional Sauna Heaters (Wood)
They have a pretty simple assembly: wood is burned in an enclosed steel frame to generate heat for a sauna bath.
The best thing about it is the aroma of wood which for the sauna purists is an uncompromisable feature in a sauna bath.
These sauna heaters have high operational cost, though they may come cheap initially.
Best suited for outdoor saunas, these heaters become the only option in areas where there is still no electricity.
The heat produced by these heaters is unregulated, however the experience will be better than an electric sauna.
To get the users dual advantage, many companies equip it with hot water tanks.
2. Electric Sauna Heaters
Electric sauna heaters make the bulk of sauna heaters sold these days and there is a very convincing reason for it.
They are cheap, easier to operate and maintain. Plus, they have a number of exciting features.
For instance, you can skip the waiting time for the sauna to heat up by programming it, or by managing it through your smartphone.
However, you will have to invest in a good electric heater for it.
Electric saunas heaters are most suitable for indoor saunas. All you have to do is to plug in the switch and wait for the sauna to heat up.
The only major drawback of the electric heaters is the operational cost which would contribute heavily to your utility bills.
3. Gas Sauna Heaters
Gas saunas are best suited for areas which have natural or LP gas in abundance.
They are mostly used in gyms, hotels, and spas as they are in essence made for commercial purpose.
Their high initial, operational and maintenance cost makes them a poor choice to be used at homes.
However in commercial areas where there is need for 8-12 hours regular heating, these saunas may turn out to be the most cost effective option.
Another major drawback is the complexity of installation and of regular maintenance.
Unless you are a technician yourself, you will have to hire a certified technician even for regular maintenance.
4. Infrared Sauna Heaters
Infrared sauna heaters have an entirely different mode of operation than the other saunas we discussed above.
They directly heat the body rather than heating the air around it.
They are fastly gaining popularity due to their low operational cost and easy installation.
You will find most infrared heaters in indoor infrared saunas. They provide a more intense while operating at low temperature.
How to Choose The Best Sauna Heater?
This comprehensive buying guide will help you steer clear of making wrong choices.
If possible make a checklist of these features whenever you are out looking for a sauna heater to buy.
The first and foremost features to look into is the construction of the sauna heater.
Most preferably it should be made up of stainless steel which is strong, durable and rust-resistant.
The choice of heater size depends mainly on the size of the sauna it is supposed to heat.
The larger the size of the sauna, the larger the size of heater you will need.
ii. Heat source type
As discussed earlier, there can be three different heat sources of the heater: electric, gas and wood.
The choice of any of them is a personal preference. However, the electric heaters are the most convenient to use and also the most reliable.
iii. Heat up time
The wood heaters take more than an hour to heat up, and are difficult to maintain.
Gas heaters are suitable for commercial purposes, and they also take a considerable amount of time to heat up the sauna.
Electric heaters take less time than others to heat up the sauna, and most importantly, they can be programmed.
So you can even skip the 15-20 minutes of waiting before the sauna is heating up.
iv. Stone capacity
One way to measure the power of a sauna heater is to find out its stone capacity.
In a nutshell, the stone capacity means the sauna heater is capable of heating up a certain weight equivalent of sauna stone material.
The higher the capacity the more powerful a sauna heater is.

The gas sauna heaters are the most expensive, whereas the electric sauna heaters are the most affordable for home saunas.
The wood heaters may come cheap initially, but they have high operational cost.
For home saunas, the worth investing option is the electric sauna hands down.

If you are spending a great amount of money into a heater, it is your right to expect a limited warranty of at least 2 years.
The design and look of a heater has nothing to do with its working, but who doesn’t want to have an aesthetically pleasing heater in the sauna?
Most preferably, the heater should be compact and is of color that matches the interior decor of the sauna.
Sauna heaters usually require manual assembly. In most cases, it requires a certain level of expertise to install the heaters.
When given an option, the preassemble heaters should always be preferred.
6. Extra features
