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.

This stainless steel hot tub stove is ideal for large hot tubs due to its high heat output. AISI316 steel ensures durability even with chlorine, bromine, or other hot tub chemicals.

Due to natural circulation, heating is efficient, and water is distributed evenly throughout the tub. This helps to reach the desired temperature faster and reduce firewood consumption.

Why choose AISI316 stainless steel?

AISI316 stainless steel has a higher resistance to more aggressive environments than AISI304. This steel is recommended when chlorine, bromine, active oxygen, foam, or other water treatment agents are used in tub water.

The doors with 4 mm heat-resistant glass allow you to observe the flame during heating, and the adjustable air supply helps to easily control the burning intensity. The hidden legs give the stove a neat and modern look.
