SERN 17cm 1 1/4 Inch Screw Plug Dual Heating Element 2500W 1250W plus 1250W 230V CR304 Stainless Steel Immersion Heater
The SERN 17cm dual-circuit screw plug immersion heating element is engineered with high-grade industrial quality for water heaters, commercial boilers, buffer tanks, and catering equipment. Delivering a total output of 2500W (split into twin independent 1250W + 1250W circuits) at 220V-240V, it reflects SERN's commitment to reliability by offering flexible power management and rapid fluid heating. Constructed from premium CR304 (Grade 304) food-safe stainless steel, this element demonstrates superior SERN manufacturing standards with extreme resistance to water corrosion, lime-scale accumulation, and continuous thermal stress. Its compact 17cm immersion length combined with a standard 1 1/4 inch threaded screw connection ensures a seamless, leak-proof fit in compact tank housings.
Technical Specifications: Brand: SERN Product Type: Screw Plug Dual Immersion Heating Element Immersion Length: 170 mm (17 cm) Power Rating: 2500W Total (1250W + 1250W Twin Circuit) Operating Voltage: 220V - 240V AC (Standard UK Mains) Body Material: CR304 Grade Stainless Steel (Food Grade) Thread Size: 1 1/4 Inch BSP Screw Plug (Vidalı) Terminal Type: Dual Circuit Threaded Screw Terminals Applications: Commercial water boilers, domestic immersion tanks, buffer vessels, catering water heaters, and industrial fluid tanks
Advantages: Built with genuine SERN quality engineering for heavy-duty thermal performance and extended operating lifespan. Twin 1250W + 1250W circuit design permits staged power activation or full 2500W dual heating capacity. Premium CR304 stainless steel resists pitting, lime-scale, and aggressive water mineral deposits. Standard 1 1/4 inch screw plug thread allows easy installation into existing threaded boss connections. Compact 17cm insertion depth enables fitting into tight water vessels and space-restricted containers. Fully compatible with standard UK 230V-240V single-phase electrical mains installations.
Disadvantages: Thread diameter (1 1/4 inch) and tank depth clearance (17cm) must be measured before ordering. Intended strictly for liquid immersion; operating without water coverage (dry firing) will void element life. Electrical installation and dual-circuit wiring should be conducted by a qualified technician.
