The tubular plug-in water heating element is designed for water storage tanks. It adopts a stainless steel (304/316L) tube body and a nickel-chromium alloy resistance wire combination process. It has a built-in magnesium rod for corrosion protection, an integrated PID temperature control module and an NTC temperature sensor, which can achieve rapid heating (average 3-5 minutes), energy efficiency ≥96%, an operating temperature range of 50℃–80℃, and supports power (1500W–5000W) customization. The surface has double-layer insulation protection, meets the IPX4 splash-proof standard, has anti-dry burning, anti-scaling coating and anti-leakage protection, is suitable for high-frequency water storage heating scenarios, has a lifespan of more than 50,000 hours, and complies with North American UL and EU CE certification.
