Differences Between Commercial Sauna Heaters: Gas Heater or Electric Heater

Saunas have evolved over the centuries. Most notably are the commercial sauna heaters used in our modern-day saunas. In today's saunas, there are primarily two different types of commercial sauna heaters available. Let's break down the differences between Am Finn's Sauna Heaters. 

Gas Sauna Heater

The Ultra Gas Sauna Heater is 100% stainless steel. It features an extra-large rock tray that instantly transforms the sauna into a steam sauna. More efficient than traditional electric heaters. 

The Ultra Gas Sauna Heater does not require the continuous replacement of costly elements. 

The proprietary sealed combustion heaters require no gas or flue connections within the sauna's interior space. This eliminates the possibility of oxygen depletion or flue products leading into the sauna. 

Electric Sauna Heater

Electric Saunas Heaters do not rust and require less maintenance than other heaters on the market. They offer better airflow, heating the room rapidly and efficiently, thus extending the life of the elements. The sleek, compact, and stainless steel design creates an as beautiful heater as it is functional. 


These units also incorporate an elevated rock tray to prevent damage during the application of water and utilize a convection-style airflow. Electric heaters are wall-mounted, wire directly into the building, and include wiring connections and lead rated for high-temperature applications. 

So what is the best heater for a commercial sauna? A Gas Heater or Electric Heater? 

If possible, a gas sauna heater is an ideal choice. Gas heaters generate a quality of heat that an electric heater cannot achieve. Gas offers a warm, friendly heat that significantly enhances the sauna experience. In addition to quality, it costs less to operate in most parts of the world than electric heaters (up to 50% less). The LTV (lifetime value) of a gas sauna heater is substantially greater than electric heaters from an operational and maintenance point of view. Whether you plan to place your sauna off the grid, our heater is not power required. You will only need a refillable propane tank, and you will be ready to enjoy your sauna. 


Annual Energy Costs 

Commercial sauna installations have considerably higher associated energy costs. According to the Tennessee Valley Authority, electricity costs approximately US $5,250 over five years for a 7'x6' sauna. The same size sauna using a gas heater will cost about 3280 USD. Besides energy savings, gas heaters do not have elements like electric heaters that require frequent replacement.
