Electric Water Heater Heating Rod with Double Heating Tube

Heating Rod for Electric Water Heater with Double Heating Tube

High efficiency electric heating rod with two heating tubes for quick heat transfer and excellent energy economy. Intended for residential, commercial, and industrial water heating systems, this dual-tube construction maximizes thermal output and reduces scaling and thermal stress. Perfect for demanding uses fast recovery and consistent performance call for.

Important attributes

Dual heating tubes
Two separate heating pipes, three kW–fifteen kW each, running concurrently to raise power to over 30 kW for fast heating.
​Should one tube fail, the other guarantees continuous hot water supply by operating.
Balanced thermal load helps to reduce hot spots and increase tube longevity.

Advanced Materials and Coatings:
Materials: Anti-scaling nano-ceramic coated corrosion-resistant stainless steel 304/316L or nichrome (NiCr) tubes.
Thermal Efficiency: ≥96% efficiency (limescale-induced loss <4% annually).
Continuous operation at 80℃–100℃; short-term at 120℃.

​Smart Safety & Control​
Overheat Protection: Automatic shutdown at 120℃ (adjustable via thermostat).
​IPX4 Waterproof: Protection against splashing and humidity.
​Optional Thermostat: Precision temperature control (±1℃) with adaptive learning.

​Customization Options​
​Power Range: 3kW–30kW per rod (dual tubes); scalable for industrial systems.
​Voltage Compatibility: AC 110V–240V/DC 12V–48V; supports global standards.
​Mounting Designs: Flange, threaded, or U-bend configurations (Φ8–30mm × L500–2500mm).

​Applications​

​Residential Water Heaters​

​Tankless Systems: Instantaneous heating for high-flow households (e.g., 6kW–12kW dual tubes).
​Hybrid Systems: Combined with heat pumps for energy-efficient domestic hot water.

​Commercial & Industrial Use​

​Hotel/Spa Boilers: Dual-tube setups for 80℃–100℃ sustained temperatures in large volumes.
​Food Service: Sanitization and steam generation in restaurants and laundries.

​Specialized Scenarios​

​Hard Water Areas: Anti-scaling coatings reduce maintenance by 50%.
​Off-Grid Systems: Solar/wind-compatible designs with battery-powered thermostat control.

​Advantages Over Single-Tube Heating Rods​

​Faster Heating: Dual tubes reduce heat-up time by 30% (e.g., 3kW model heats 50L water to 60℃ in 8 minutes).
​Higher Power Density: Ideal for high-capacity systems without increasing rod size.
​Enhanced Durability: Even heat distribution minimizes corrosion and thermal fatigue.
​Cost-Effective: Parallel operation lowers energy consumption by 15% vs. single-tube models.
