How does an outdoor tub stove work?

An external hot tub stove is mounted next to the hot tub and connected to water connections. The water enters the stove by natural circulation, heats up from the combustion chamber, and returns to the hot tub.

1. Water from the tub falls into the stove.
2. The water heats up quickly in the combustion chamber.
3. The dried water returns to the tub.

Integrated air circulation pipes improve heat exchange, making water heat more efficiently and evenly.

Advantages of AISI316 stainless steel

AISI316 stainless steel is recommended when disinfectants, chlorine, bromine, active oxygen, foam, or other water treatment additives are used in the tub water. Compared to AISI304, AISI316 better withstands a more aggressive water environment.

This stainless steel hot tub stove features a door with 4mm tempered glass, adjustable air supply, and concealed structural legs. This ensures convenient use, a tidy appearance, and long-lasting performance.
