Thanks to the durable AISI316 stainless steel, this external hot tub stove is perfectly suited for use with chlorine, bromine, and other hot tub chemicals.<\/p>\n<p>This model does not take up space inside the hot tub, leaving all the space for comfortable relaxation. Due to its higher power, the stove is perfect for larger volume hot tubs, homesteads, SPA areas, and hot tub rental businesses.<\/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>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.<\/p>\n<p>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.<\/p>\n<h2>Why choose AISI316 stainless steel?<\/h2>\n<p>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.<\/p>\n<p>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.<\/p>\n<p>If you are looking for a reliable <strong>wood-fired oven 45 kW AISI316<\/strong>, this IGNISTA model ensures fast water heating, durability, and efficient heat transfer in all seasons.<\/p>\n<h2>Technical data<\/h2>\n<ul>\n<li>Galley: 45 kW<\/li>\n<li>Efficiency ratio: up to 80 %<\/li>\n<li>Length: 750 mm<\/li>\n<li>Height: 660 mm<\/li>\n<li>Width: 485 mm<\/li>\n<li>Mushroom thickness: 1.5 mm<\/li>\n<li>Material: AISI316 stainless steel<\/li>\n<li>Chimney opening: \u00d8125 mm<\/li>\n<li>Water connections: \u00d848 mm<\/li>\n<li>Door with 4 mm heat-resistant glass<\/li>\n<li>Integrated rear air circulation chambers<\/li>\n<li>Hidden structural feet<\/li>\n<\/ul>\n<p>This AISI316 model is one of the best choices in the IGNISTA range when a powerful, resistant, and durable outdoor hot tub stove is required.<\/p>\n<p>Not sure which stove is best for you?<br \/>\n<a href=\"https:\/\/ignista.lt\/en\/integruota-ar-isorine-kubilo-krosnele\/\" target=\"_blank\" rel=\"noopener\">Read our guide to integrated and external hot tub stoves<\/a>.\n<\/p>\n<p>Check out our other<br \/>\n<a href=\"https:\/\/ignista.lt\/en\/product-category\/krosneles\/\" target=\"_blank\" rel=\"noopener\">Baking oven<\/a><br \/>\nat<br \/>\n<a href=\"https:\/\/ignista.lt\/en\/product-category\/kubilu-priedai\/\" target=\"_blank\" rel=\"noopener\">tub attachments<\/a>.\n<\/p>\n<p>Learn more about the properties of stainless steel<br \/>\n<a href=\"https:\/\/worldstainless.org\/\" target=\"_blank\" rel=\"noopener\">World Stainless<\/a><br \/>\non the website.<\/p>","protected":false},"excerpt":{"rendered":"<p><strong>Wood-fired stove 45 kW AISI316 75 cm<\/strong> \u2013 our most powerful external hot tub stove, made of AISI 316 stainless steel.
