What Are the Differences Between Wet and Dry Sauna Heaters?

The primary difference between wet and dry sauna heaters is the amount of moisture in the air. A dry sauna heater heats the air in the sauna, creating a hot and dry environment. A wet sauna heater, on the other hand, produces steam, which adds humidity to the air, creating a more humid environment.

Here’s a table with the main information about dry and wet sauna heaters:
