This product is designed with an integrated heating tube at the bottom of a stainless steel boiler. It is specially developed for high-efficiency steam generation scenarios (such as coffee machines, hanging irons, and sauna equipment) to enhance durability and thermal efficiency. It uses a 304 food-grade stainless steel body and a high-temperature resistant alloy heating tube, which increases corrosion resistance by 50% and supports continuous high-temperature operation; the PID temperature control system achieves 3-second heating and ±1°C precise temperature control, which is suitable for steam explosion-type home appliances. The bottom spiral heating tube structure optimizes heat conduction, reduces the risk of local overheating, and is equipped with an anti-scaling coating to reduce maintenance frequency. Modular installation is compatible with compact models, complies with CE and RoHS certifications, is safe and reliable, and helps to improve the life and energy efficiency of steam equipment.

Our Stainless Steel Boiler Bottom with Heating Tubes is a critical component of electric boiler heaters, serving as the primary heat transfer and energy conversion module in steam generation systems. Designed for integrated installation at the base of boilers, it combines a durable stainless steel base with embedded heating tubes to efficiently convert electrical energy into thermal energy, heating water to produce high-quality steam. Widely used in household appliances (e.g., steam irons, espresso machines, electric steamers, humidifiers) and commercial/industrial systems (industrial steam generators, commercial instantaneous steam systems), it ensures stable, rapid steam output while withstanding prolonged exposure to water, heat, and mechanical stress.
