The Ultimate Guide to Choosing the Right Type of Sauna Heater for Your Home

Welcome to the world of relaxation, rejuvenation, and warmth.

We're talking about the world of home saunas.

A home sauna is a sanctuary, a space to unwind after a long day, and a place to rejuvenate your body and soul. But the heart of this sanctuary is its heater - the engine behind the heat that makes the sauna experience truly therapeutic and beneficial.

Why is the sauna heater so crucial? It determines the heat quality, energy usage efficiency, and, ultimately, your overall sauna experience. Today, we're diving deep into understanding sauna heaters and helping you choose the right one for your home sauna.

Understanding Sauna Heaters

A sauna heater is more than just a heat source.

It's the cornerstone of your sauna experience. The heater determines how quickly your sauna reaches the desired temperature, the nature of the heat (dry or humid), and the overall energy efficiency of your sauna.

There are different types of sauna heaters, each with its unique characteristics, pros, and cons. Let's explore them further.

Types of Sauna Heaters

Sauna heaters can be primarily categorized into four types:

  1. Electric Heaters: Electric sauna heaters are popular in urban areas for convenience. They're easy to install, control, and maintain. However, they do require a suitable electrical setup and can lead to increased energy costs.

  2. Wood-Burning Heaters: A traditional choice, wood-burning heaters are loved for the authentic sauna experience they offer. The aroma of burning wood and the nature of the heat produced is unmatched. They're ideal for outdoor saunas or homes in rural areas with ample wood supply.

  3. Infrared Heaters: Infrared heaters are a modern solution. Instead of heating the air, they heat the body directly, offering a different kind of sauna experience. They're energy-efficient and can be installed in smaller spaces.

  4. Gas Heaters: Gas heaters are less common for home saunas but are a viable option if you have access to natural gas or propane. They're efficient but require professional installation to ensure safety.

Each type of heater has its advantages and disadvantages, and the right one for you depends on various factors.

The Sauna Experience: From Heat to Steam

Sauna heaters provide the heat necessary for the sauna experience. They warm the sauna room, often to levels of heat ranging from 70 to 100 degrees Celsius. This heat promotes sweating, which many sauna enthusiasts believe helps with detoxification and relaxation. The process of sprinkling water on the sauna rocks creates a steam room effect, increasing humidity and enhancing the relaxing sauna atmosphere.

In traditional saunas, the crackle of a wood-burning heater adds a sensory element that many users enjoy. The combination of heat, steam, and the gentle crackle of fire contributes to an authentic sauna experience that sauna purists cherish.

Each type of heater has its advantages and disadvantages, and the right one for you depends on various factors.

Factors to Consider When Choosing a Sauna Heater

Choosing the correct sauna heater is a process that requires careful consideration of several factors. Let's explore some of those factors so you can make the best decision around your sauna heater purchase.

Type of Sauna

Firstly, the kind of sauna you have or intend to build will significantly influence your choice of the heater.

Infrared saunas require infrared heaters, while traditional saunas can accommodate electric or wood-burning heaters. Outdoor saunas often benefit from wood-burning heaters, though electric heaters are also possible if you have outdoor electrical access.

Size of Your Sauna

The size of your sauna plays a significant role in choosing your heater.

A larger sauna will require a heater with more power to heat the space efficiently. Similarly, a smaller sauna should not be paired with a powerful heater as it could unnecessarily make the temperature uncomfortably high or increase energy consumption.

The output of sauna heaters is measured in kilowatts (kW), and a general rule of thumb is that you'll need 1 kW of power for every 45 cubic feet of space in your sauna. Always check the manufacturer's recommendations to ensure you choose the correct size.


Your budget is a critical factor when deciding on a sauna heater.

  • Electric heaters can have a lower upfront cost but can lead to higher energy bills.
  • Wood-burning heaters require an investment in the heater and installation, but wood costs are typically lower than electricity, making it more affordable in the long run.
  • Infrared heaters are energy-efficient, leading to lower ongoing costs, but they can be expensive to install.
  • Gas heaters require professional installation and access to natural gas or propane, which may not be convenient or affordable for all.

It's important to consider the upfront and ongoing costs when choosing a heater for your sauna.

Ventilation and Safety

Ventilation and safety are paramount when choosing a sauna heater.

Electric heaters and infrared heaters are generally considered safe as they don't emit gases and require minimal ventilation. However, they must be correctly installed to avoid electrical hazards.

Wood-burning heaters create a genuine sauna experience but require good ventilation to exhaust the smoke and gases produced safely. They also need a chimney, adding to the complexity of installation.

Gas heaters, while efficient, require proper venting for the combustion gases. Professionals must install them to ensure safety and compliance with local regulations.

Ease of Use and Maintenance

Lastly, consider how easy the heater is to use and maintain.

Electric heaters and infrared heaters are straightforward to operate, often with digital controls, and require minimal maintenance.

Wood-burning heaters offer a more hands-on experience. Some people enjoy the process of tending to the fire, while others may find it cumbersome. They also require regular cleaning to remove ash.

Gas heaters are easy to use but require regular maintenance to ensure they burn efficiently and safely.

Making an Informed Decision

Now that you understand the different types of heaters and the factors to consider, it's time to make an informed decision.

Remember, your ultimate goal is to enhance your sauna experience. Your heater should align with your sauna type, size, budget, safety requirements, and personal preferences. Consider consulting with a sauna professional or doing further research if you're unsure.

Installing Your Sauna Heater

Once you've chosen the right sauna heater, the next step is installation.

While it might be tempting to install the heater yourself, it's often best to leave this task to professionals, particularly for gas and wood-burning heaters. Professional installation ensures safety, efficiency, and compliance with any local regulations.

Suppose you've chosen an electric or infrared heater. In that case, these can be installed DIY, but always follow the manufacturer's instructions closely, and don't hesitate to call in a professional if you're unsure.

Maintaining Your Sauna Heater

Once your sauna heater is up and running, maintaining it is key to ensure longevity and optimal performance.

Regular checks of the electrical components and cleaning of the heaters are typically sufficient for electric and infrared heaters. Wood-burning heaters require regular ash removal and inspection for any soot or creosote build-up in the chimney. Gas heaters should be inspected periodically to ensure the gas burns cleanly and the venting works correctly.

Final Words

The perfect sauna heater for your sauna ultimately depends on your preferences, available utilities, and intended use. A wood-burning sauna heater could offer an authentic, traditional sauna experience, while an electric sauna heater provides a modern, convenient solution. Gas sauna heaters can quickly heat larger saunas, and infrared sauna heaters provide a unique, direct-heat experience.

Whether you're considering a traditional Finnish sauna, a contemporary electric-heated sauna, or an innovative infrared sauna, the correct sauna heater type can significantly enhance your sauna sessions. Consider the different types of sauna heaters available, consider your preferences and practicalities, and consult a reputable sauna company to ensure you choose the right sauna heater for your sauna room, creating an ideal, relaxing sauna experience.

With this guide, we hope you are now equipped to make an informed decision. Remember, the journey to relaxation and rejuvenation begins with the right heater. Choose wisely, and your home sauna will become a cherished sanctuary for years to come.

Enjoy your sauna journey!
