electric water heater element

Product Applications

Home appliances: water storage electric water heaters, instant water dispensers, solar auxiliary heating modules, embedded coffee machines.

Industrial equipment: commercial boiler circulation systems, swimming pool thermostats, food processing high-temperature sterilization equipment

Product parameters and specifications

Power range:
    Household: 1.5kW–5.5kW (storage/instantaneous)
    Commercial: 6kW–20kW (hotel/swimming pool/industrial hot water system)

Working voltage: 110V/220V single-phase AC or 380V three-phase AC (global power grid compatible, error ≤±5%).

Resistance value: 3Ω–40Ω (accurately matched by voltage and power, error ≤±3%).

Working temperature: Continuous and stable operation of 75°C–95°C (short-term tolerance of 120°C, suitable for high-temperature disinfection needs).

Material:

    Heating element: food-grade stainless steel 316L (corrosion-resistant, anti-scale deposition) or copper-nickel alloy (extremely fast heat conduction, high-temperature oxidation resistance).

    Insulation layer: high-purity magnesium oxide ceramic (hydrolysis-resistant, thermal shock-resistant, and leakage-proof).
​​Dimensions: Length 150mm–600mm, diameter Φ10mm–30mm (supports U-shaped, spiral, plate or special-shaped customization).
​​Service life: 10,000–35,000 hours (based on water quality and cleaning frequency, anti-scaling coating extends life).
​​Customizable services: support power, voltage, shape adjustment, optional anti-scaling coating, dual-zone temperature control, explosion-proof certification, etc.

Core advantages

Extreme anti-scaling performance:
Magnesium oxide ceramic insulation layer + stainless steel/copper-nickel alloy material, anti-calcium magnesium scale deposition efficiency ≥95%, reducing cleaning frequency by more than 80%.
Surface nano-hydrophobic coating technology, anti-scaling performance is 4 times higher than traditional heating tubes.
​​Extreme heating and energy saving:
The thermal conductivity of the copper-nickel alloy heating element is ≥180W/m·K, and it heats up to 90°C within 30 seconds, which is suitable for instant electric water heaters and reduces energy consumption by 15%.
​​Precise temperature control technology​​:
±0.8°C temperature control accuracy, supports segmented heating (preheating/constant temperature/fast heating), prevents overheating or hot and cold, and is suitable for constant temperature shower/bathtub needs.
​​Super corrosion resistance​​:
316L stainless steel is resistant to hard water corrosion (pH 5–9), copper-nickel alloy is resistant to high temperature oxidation, and its life is more than 50% longer than ordinary models.
​​Multiple safety protections​​:
IPX7 waterproof rating, triple protection for overheating/overvoltage/dry burning (≥90°C automatic power off), compliant with CE, UL, CCC, RoHS certification.
​​Compact adaptable design​​:
The ultra-thin spiral design is seamlessly embedded in the water storage tank or instant module, and is suitable for split/integrated electric water heaters.
​​Smart control compatibility​​:
Supports PWM power regulation and IoT access (APP remotely controls water temperature/mode), and is suitable for smart water heater systems.
​​Global market adaptation​​:
Compatible with 110V/220V voltage, supports CE, FCC, CB certification customization, and adapts to European, American, Asian, and Middle Eastern market standards.
