The external design does not take up space inside the hot tub, leaving all the space for comfortable relaxation.<\/p>\n<h2>How does an outdoor tub stove work?<\/h2>\n<p>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.<\/p>\n<ol>\n<li>Water from the tub falls into the stove.<\/li>\n<li>The water heats up quickly in the combustion chamber.<\/li>\n<li>The dried water returns to the tub.<\/li>\n<\/ol>\n<p>Integrated rear air circulation chambers improve heat exchange, making water heat more efficiently and consuming less firewood.<\/p>\n<h2>Advantages of AISI304 stainless steel<\/h2>\n<p>AISI304 stainless steel is one of the most commonly used materials in the production of hot tub stoves. It is resistant to moisture, corrosion, and temperature fluctuations, making it suitable for long-term outdoor use.<\/p>\n<p>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.<\/p>\n<h2>Hot tub stove 45 kW AISI304 for intensive use<\/h2>\n<p>The 75 cm model is ideal for larger outdoor hot tubs, country homes, SPA areas, and hot tub rental businesses.
