How Does a Wood Fired Hot Tub Work?
A wood-fired hot tub operates through a straightforward yet efficient mechanism that utilizes wood as its heating source. Here’s how it works:

Temperature Control: Users can adjust water temperature by controlling the intensity of the fire. More firewood results in quicker heating, while reducing the fire will cool the water gradually.
-
Thermal Efficiency: Wood-fired hot tubs tend to retain heat effectively due to their insulated designs, allowing for longer use without needing constant replenishment of firewood.

Natural Experience: The wood-burning process imparts a rustic charm, enhancing the experience with the ambiance of flickering flames and the natural scent of burning wood.
