Wood vs. Electric Sauna Heaters: What’s Right for You?

When designing your sauna, one of the biggest decisions you'll make is the type of heater you install. The heater is the engine of the sauna—it dictates how quickly your sauna warms up, the kind of experience you’ll have, and how much effort it takes to maintain.

At The Sauna Store, we carry both electric and wood-burning sauna heaters, each with their own advantages depending on your space, preferences, and lifestyle.

In this article, we’ll compare wood and electric sauna heaters across several key categories to help you make an informed decision.

Installation Requirements

Electric Sauna Heaters
Electric heaters are generally easier to install—especially indoors. They do require access to a 240V/1PH electrical connection and must be installed by a licensed electrician. Modern electric heaters often feature digital controls or smartphone integration, making them highly convenient.

Wood-Burning Sauna Heaters
Wood stoves require a chimney or flue for proper ventilation and must be installed in compliance with local fire codes. These are better suited for outdoor saunas or off-grid cabins where electricity may not be available. You’ll also need regular access to dry firewood.

Heat-Up Time

Electric Heaters
Most electric heaters will heat a well-insulated sauna in 30–45 minutes. With smart controls or scheduling, you can set the sauna to heat before you arrive—ideal for busy schedules.

Wood Heaters
Wood stoves generally take longer to heat—often 45 minutes to over an hour depending on the size and outdoor conditions. However, the wait is part of the charm for many sauna traditionalists.

Experience & Atmosphere

Electric Heaters
Electric heaters offer precision. You can control exact temperatures, and some models include Wi-Fi apps for remote monitoring. They create clean, dry heat and tend to be more consistent.

Wood Heaters
Nothing beats the ambiance of a crackling fire. The soft aroma of burning wood, the flickering flame through a fire window, and the organic feel make wood-burning heaters a favorite for purists. The steam (löyly) from wood heaters tends to feel softer and more natural.

Maintenance & Operation

Electric Heaters
Low-maintenance. Once installed, electric heaters require minimal upkeep aside from cleaning stones and checking wiring annually. Operation is simple—just press a button or set a timer.

Wood Heaters
Wood heaters require more hands-on effort. You’ll need to chop or purchase wood, clean ash regularly, and inspect the chimney. The extra work is worthwhile for those who enjoy the process.

Cost & Efficiency

Electric Heaters
Upfront cost is often lower, but you’ll see a small increase in your electricity bill depending on sauna usage. Over time, electric operation is efficient for those who sauna frequently.

Wood Heaters
Wood heaters can be more expensive to install due to chimney and ventilation requirements. However, if you have access to free or low-cost firewood, ongoing operation costs may be lower—especially off-grid.
