This design helps to retain heat inside the stove for longer, resulting in more heat transfer to the water and more efficient wood consumption.<\/p>\n<h2>AISI316 bathtub heater 37 kW \u2013 main advantages<\/h2>\n<ul>\n<li>37 kW heating capacity<\/li>\n<li>75 cm overall length<\/li>\n<li>480 mm pakura<\/li>\n<li>AISI 316 stainless steel<\/li>\n<li>Increased resistance to chemicals and moisture<\/li>\n<li>Combustion partition for more efficient heating<\/li>\n<li>Fast hot tub water heating<\/li>\n<li>Lower wood consumption<\/li>\n<li>Wood-fired<\/li>\n<li>Suitable for intensive use<\/li>\n<\/ul>\n<h2>Why choose an AISI316 hot tub stove?<\/h2>\n<p>AISI316 stainless steel is recommended when care products, disinfectants, foam or other additives are used in the hot tub water. Such an environment can be more aggressive towards metal over time, making AISI316 steel a safer choice for greater resistance and a longer lifespan.<\/p>\n<p>Compared to AISI304 steel, AISI316 offers better resistance to chemical environments. This makes this oven particularly suitable for rural tourism farms, spa areas, rental hot tubs, and intensive use.<\/p>\n<h2>AISI316 bathtub burner with combustion baffles<\/h2>\n<p>The combustion baffles installed inside this model prevent hot combustion gases from immediately exiting into the chimney. The heat moves longer inside the stove, thus transferring more energy to the water.<\/p>\n<p>This solution helps to heat the hot tub water faster, reduce wood consumption, and improve overall heating efficiency. This is especially relevant when using the hot tub during the cold season or when heating a larger amount of water.<\/p>\n<h2>How does an AISI 316 hot tub stove work?<\/h2>\n<p>The heater is installed next to the tub and connected to the water inlet and outlet. Water circulates naturally through the heater, is heated by the combustion chamber, and returns to the tub already warmed.<\/p>\n<ol>\n<li>Water from the tub goes into the stove<\/li>\n<li>Heat is transferred through stainless steel walls<\/li>\n<li>The drying water returns to the tub<\/li>\n<\/ol>\n<p>Due to natural circulation, the system operates simply, reliably, and does not require complex additional solutions.<\/p>\n<h2>AISI316 hot tub stove \u2013 technical information<\/h2>\n<ul>\n<li>Stove type: external log-fired<\/li>\n<li>Power: 37 kW<\/li>\n<li>Length: 75 cm<\/li>\n<li>480 mm<\/li>\n<li>Material: AISI316 stainless steel<\/li>\n<li>Fire partition: yes<\/li>\n<li>Heating: firewood<\/li>\n<li>Exhaust connection: \u00d8125 mm<\/li>\n<li>Water connections: \u00d848 mm<\/li>\n<li>Outdoor hot tub covers<\/li>\n<\/ul>\n<h2>AISI316 vs. AISI304 \u2013 which to choose?<\/h2>\n<p>AISI304 steel is an excellent choice for standard hot tub use when water treatment chemicals are used moderately. However, the AISI316 version is recommended when greater chemical resistance, more intensive use, and a more aggressive water environment are desired.<\/p>\n<p><strong>AISI316 bathtub stove 37 kW<\/strong> With a 75 cm long body and a 480 mm firebox, it is designed for intensive use. AISI316 steel offers greater resistance to water chemistry, making this outdoor hot tub stove ideal for use with disinfectants and other water treatment products.<\/p>\n<h2>Who is this external hot tub stove suitable for?<\/h2>\n<p>This model is suitable for both private use and rural tourism homesteads, spa areas, or rental hot tubs. It is a good choice when the hot tub is used frequently and various cleaning agents are used for water maintenance.<\/p>\n<p>If customers frequently use foams, fragrances, sanitizing agents, or other spa water additives, the AISI316 version is a safer and more durable choice.<\/p>\n<h2>Why choose an Ignis stove?<\/h2>\n<p>Ignista furnaces are manufactured with a focus on efficient water heating, reliable construction, and durability.
