How to Choose A Sauna Heater? (Buying Guide)

Choosing a sauna heater is not easy. Below, we have compiled a list of things you need to consider before purchasing one.  

1. Quality

The first factor to consider is the quality of the sauna heater’s build. What are the materials used in its construction? The heater will be exposed to high temperatures, therefore you want something durable. You’ll also want to make sure that you can pour water on it without exposing it to rust or corrosion. From years of experience, we can tell that the best material for a heater is stainless steel because it is resilient and long-lasting. 

2. Heater Type 

a. Heater & Room Size 

Sauna heaters come in various sizes. A small heater will serve a small sauna room that accommodates only a handful of people. And of course, a large heater is built for a large sauna room. But they are difficult to handle and move about. 

b. Heat Source 

There are four different heat sources to choose from. Those are wood, electricity, gas, and infrared. 

Wood sauna heaters offer a traditional experience whereas electric sauna heaters are modern and easier to control. Gas sauna heaters are your best option if you want a short heat-up time. And the infrared heating panels are the most eco-friendly and low maintenance. 

c. Heat-Up Time

Some sauna heaters take longer to heat up than others. Some retain heat longer than others. Ideally, you should choose one that heats up quickly and retains heat for a long time. Wood sauna heaters take over an hour to heat up and they don’t retain heat for a long time. Electric sauna heaters and infrared panels also take a significant time to heat up but when compared to wood heaters, they are quicker and can retain heat for a long time. Gas heaters are the quickest heaters in the market which is why they are popular in commercial spaces. 

d. Stone Capacity

The power of a sauna heater is often measured by the weight of sauna rocks it can accommodate. A small-capacity heater won’t do well for a large sauna room, and a large capacity could provide a lot more heat than you need. So, it’s important to consider the rock capacity, the size of the room, and the amount of steam you want. Additionally, the weight of the rocks will make the sauna heavier to handle, so you’ll also want to consider a stone capacity that is light enough for you to carry without difficulties.

Electric Heater Voltages

If you are planning on buying an electric sauna heater, their voltage capacities are worth noting. Electric heaters come with one of two voltage capacities – 110v or 220v. 

110v Sauna Heaters

A 110v sauna heater is perfect for a small sauna room. It’s easy to set up. You can plug it into a power outlet and switch it on. That’s it. 

220v Sauna Heaters

A 220v sauna heater packs twice as much power so it’s best suited for larger sauna rooms. It takes a while to heat up but you’ll need a qualified electrician to set it up properly.

3. Cost 

The primary factors that determine the cost of a sauna heater are the source of heat and the heating capacity. If your budget is high, go for a gas-powered sauna heater. Otherwise, get an electric sauna heater which is much more affordable. Traditional wood heaters, unlike popular belief, are not economical. There is a low initial cost, but they are expensive to operate and maintain. 

4. Look 

Select a sauna heater that matches the style of your sauna. An elegant unit can make the room more interesting and add a welcoming feel to your sauna. A pain one can help your sauna look fuller without drawing attention to the unit.

5. Assembly

You’ll need some level of expertise to assemble a sauna heater correctly. For instance, setting up an electric heater requires help from an electric expert. Alternatively, you can opt for a pre-assembled heater. Such heaters are costlier, it’s not a hassle to set them up. 

6. Extra Features 

Look out for additional features like remote control settings on electric heaters and hot water tanks on wood sauna heaters, among other things.

Wet vs. Dry Sauna Heaters 

A wet sauna heater is one where you splash water over the sauna rocks and it produces steam to fill the room. If you restrain from using water, the heater becomes a dry sauna heater. Wood or electric sauna heaters can function both as wet and dry sauna heaters.

Types of Sauna Heaters

There are four types of sauna heaters: wood, electric, gas, and infrared. In the following section, you will find an overview of each type of heater. Let’s dive in:

electric, gas and wood burning stoves
Electric, gas, and wood-burning sauna heaters

1. Traditional Sauna Heaters (Wood)

Wood-burning sauna heaters are affordable and offer a traditional sauna experience. The units are quite powerful and can be used in large sauna rooms. You can use a traditional wood sauna heater for both wet and dry sauna experiences. 

2. Electric Sauna Heaters 

An electric sauna heater comes equipped with simple controls and it’s pretty straightforward to use. For indoor saunas, electric heaters are an ideal choice. That said, electric saunas are expensive. The initial cost is often high and its frequent use will lead to spikes in your electric bill. Luckily, this type of sauna heater has a wide temperature range, allowing you to customize your heating experience and reducing your bill. 

3. Gas Sauna Heaters 

Gas sauna heaters are ideal for commercial sauna spaces. These types of heaters can heat up quickly, and they are quite durable. Unfortunately, the heaters are not very eco-friendly because they use petroleum-based gas. Plus, operating the heaters requires technical expertise.

4. Infrared Sauna Heaters

Infrared sauna heaters are both eco-friendly and easy to operate. They are low maintenance and therefore very cost-efficient. The biggest downside of an infrared sauna is that you can’t produce steam. It’s strictly a dry sauna.

Electric vs. Far Infrared Sauna Heaters 

Electric and infrared sauna heaters are the most common type of sauna heaters. As the name suggests, electric heaters use electricity to produce heat and infrared heaters use infrared radiation. Unlike an electric heater, an infrared heater heats the person and not the atmosphere. 

Beyond this, there are differences in temperature, heat-up time, and even the social experience. The temperature will range between 150 and 185º F in an electric sauna and in a far infrared sauna it will range between 120 and 140º F. A traditional electric sauna can take up to 40 mins to heat up whereas an infrared sauna starts heating the body almost instantly. Electric saunas lend themselves for an intimate social gathering but infrared saunas are meant to be a private escape. Learn more.
