How to Choose a Sauna Heater: Electric vs. Wood-Burning Options

How to Choose the Perfect Sauna Heater: Your Complete Guide
Selecting the right sauna heater is essential, as it serves as the heart of your sauna experience. With a wide variety of options available, making the right choice can feel overwhelming. Whether you’re deciding on the type of heater, power level, or manufacturer, this guide will help you choose the ideal sauna heater to suit your needs.
Electric or Wood-Burning Sauna Heater: Which One is Right for You?
One of the most debated topics among sauna enthusiasts is whether to choose an electric sauna heater or a wood-burning sauna heater. Both options have loyal fans, and the decision ultimately depends on your lifestyle and preferences.
Benefits of Electric Sauna Heaters
Electric heaters are perfect for modern, fast-paced lifestyles. Here’s why they’re a popular choice:
- Convenience at Your Fingertips: Easily start the heater with a button press or via a mobile app for remote operation.
- Consistent Temperatures: Electric heaters automatically maintain your desired temperature throughout the session.
- Low Maintenance: No need for chimneys, firewood, or ash cleanup.
- Space-Saving: Their compact design makes them easy to install in almost any setting.
Electric heaters are ideal for those who want a quick, hassle-free sauna experience without compromising on comfort.

Advantages of Wood-Burning Sauna Heaters
For traditionalists and those who enjoy a hands-on experience, wood-burning heaters offer an authentic sauna atmosphere:
- Traditional Ambiance: The crackling of fire, the glow of the flames, and the aroma of burning wood create an immersive sauna ritual.
- Energy Independence: Wood heaters don’t rely on electricity, making them cost-efficient and perfect for off-grid use.
- Natural Appeal: Many users appreciate the calming effect of tending a fire and heating the sauna as our ancestors did.
Wood-burning heaters are perfect for those who value the process of sauna heating as part of their relaxation.

Choosing the Right Heater Power
Selecting the correct power for your sauna heater is critical for optimal performance. Sauna heaters are designed to heat specific room sizes, but it’s important to consider more than just the measured volume of your sauna.
Key Factors to Consider
- Room Size: Calculate the total volume of your sauna in cubic meters (m³). The general rule of thumb for electric heaters is about 1 kW of power per cubic meter.
- Uninsulated Surfaces: Account for non-insulated areas like glass doors, stone walls, or windows. Each square meter of uninsulated surface increases the heating requirement by an extra 1 m³.
- Location or climate: An outdoor sauna in a cold climate will need more power to heat up than an indoor sauna would, so keep that in mind when choosing your heater.
Failing to account for these factors can result in an underpowered heater, leading to longer heating times and a subpar sauna experience. For example, an overheated wood-burning heater or a burned-out electric heater is often a sign of inadequate sizing. Properly sizing your heater ensures faster heating and an enhanced sauna experience. When in doubt, it is generally recommended to size up your sauna heater.
Sauna Heater Trends: What’s Popular Today?
Current trends favor heaters with a large stone capacity and minimal exposed metal. This design delivers smooth, long-lasting steam for a more enjoyable sauna session. Both electric and wood-burning heaters are available in these styles.
