Buyer’s Guide

Shopping for a sauna heater can be quite challenging. They are not the kind of products that we would regularly buy. It’s even harder to ask for advice from other people because not everyone has a sauna at home.

To ensure that you get a reliable sauna heater, we listed some of the factors that you need to consider when making your purchase. You’ll find this guide extremely helpful regardless of whether you are a first-time buyer or not.

1. The Size of the Sauna

Sauna heaters are built for different sauna room sizes. That’s why you have to know the dimensions of your sauna room before you make a purchase. If the two do not correspond, you’ll end up with an under-heated or overheated sauna room.

You can refer to the heater’s product description to check if the manufacturer has provided any information about its heating capacity. In case you fail to get the information you need, you can also contact the manufacturer directly and have them address some of your concerns.

2. Type of Sauna

You can’t settle for a random sauna heater when there are different types of saunas on the market. If you do, you might end up with a heater that you can’t use.

Purchase an infrared sauna heater if you have an infrared sauna. Even though it might have higher maintenance costs compared to other types of heaters, it is the only model that is compatible with such a sauna. You’ll also get to experience all the health benefits associated with infrared saunas since you’ll finally be able to make use of your sauna room.

You should consider wood-burning sauna heaters if you are after a traditional or authentic sauna experience. However, if you rarely have the time to set up such heaters, you also have the option of getting an electric sauna heater. Their initial cost is low and they are also easy to maintain. The only catch is that you’ll have to deal with an increase in your electrical bill if you choose to do so.

3. How Fast the Sauna Heats Up

Some sauna heaters take longer to heat up compared to others. However, this doesn’t necessarily mean that a model that heats up quickly is always the best option. Depending on the material used, a heater can have more temperature inertia. What this means is that the heater is likely to have better heat retention even though it might take a while for it to heat up.

An ideal heater should be balanced in terms of how long it takes to heat up and the amount of time it can retain its heat. That way, you won’t end up with a model that will have you waiting impatiently or one that can only keep the sauna hot for a limited time.

4. Features

You should also look at features such as the power rating of the sauna, the controls, or whether or not it’s a stand-alone or a wall-mounted heater.

The space you have available should also help you decide whether you want a stand-alone or wall-mounted heater. Wall-mounted heaters are great for small saunas. You should consider getting such models if you are dealing with space constraints.

Set some time aside and discuss matters relating to power requirements or ratings with a professional. As for tech, check whether the heater comes with programmable controls or if you can preset/ automate it for added convenience.

5. Installation

You should get a sauna heater that you can easily install without the help of a technician. Avoid going for something that has a complex set up unless it’s necessary.


1. What is the best sauna heater?

The best sauna heater is one that is compatible with your sauna. It should have the capacity to heat your sauna room efficiently. The model should also heat up within a reasonable amount of time, and needs to have excellent heat retention. If possible, make sure you go for a heater that has convenient controls and programmable settings.

2. Can I make a sauna heater at home?

Yes. It’s possible to make your own sauna heater. There are several credible sites on the internet that can help you build a DIY sauna heater. You just have to make sure that you do your due diligence and use information from reliable sources.

3. Is it safe to use water on an electric sauna heater?

Yes. You can use water on an electric sauna heater. The heaters are designed to produce steam when water is sprinkled on the sauna rocks. So you shouldn’t worry about it being a possible shock hazard.

However, you need to practice caution so that you do not add too much water at once. Otherwise, you will end up reducing the heat in the sauna room because the rocks will cool off quickly. You should also know that adding water to your heater may reduce the life span of the heating elements.


We recommend the Finlandia FLB-60 as the best sauna heater. It features professional-grade heating elements and is certified by the CE and ETL. You can also preset it up to 8 hours, giving you more than enough time to schedule your sauna session in advance. The heater also comes with 50 pounds of sauna rocks, and the brand offers excellent customer service.

The Harvia M3 Wood burning sauna heater is also worth considering. It’s a great choice for people who have large sauna rooms and provides efficient air circulation and even heat distribution. You’ll also like its durable exterior and glass door design.
