Water heater heating elements
Differences in heating of electric heating water heaters
The design and technological adaptation of heating accessories is the fundamental distinction of electric heating water heaters: The water storage type is suited for centralized water usage in homes; the instantaneous type depends on the highpower rapid heating of the integrated heating module to satisfy immediate needs; the electric-assisted solar water heater is bolstered by auxiliary electric heating tubes to balance the instability of solar energy.
When deciding, you should take into account the family’s water consumption patterns (such as the number of individuals and the timing of water use), local climate (such as winter temperature and daylight duration), and installation circumstances (such circuit load and room size). Prioritize the material of the heating accessories (such as nickelchromium alloy corrosion resistance and copper thermal conductivity), safety design (such as waterelectricity separation and leakage protection), and energy efficiency level (such as level 1 energy efficiency models are more energyefficient).

Electric water heater heating elements
The core heating accessory of the storage-type electric water heater is the built-in electric heating tube (also known as the heating rod), which is composed of a resistance wire (nickel-chromium alloy), an insulating layer (magnesium oxide powder) and a metal shell (stainless steel or copper). Its working principle is: the current passes through the resistance wire to generate Joule heat, which is transmitted to the shell through the insulating layer to directly heat the water in the water tank.
Key features:
Common power is 1500-3000W, the higher the power, the faster the heating; the stainless steel shell has strong corrosion resistance, and the copper shell conducts heat faster but the cost is high; after long-term use, the inner wall of the water tank is prone to scale and needs to be cleaned regularly; the water tank capacity is 40-80L, which is suitable for continuous water use by multiple people in the family, but it needs to be preheated in advance and occupies a large space (diameter 50-70cm).
Solar water heater heating elements
Electric-assisted solar water heaters are mainly solar energy collectors, supplemented by electric heating. Its core heating accessories are auxiliary electric heating tubes (built-in water storage tanks), usually nickel-chromium alloy heating rods, with a power of 1500-3000W (similar to water storage type).
Working logic:
On sunny days, the solar collector absorbs heat through vacuum tubes/flat plates to heat the water tank; on rainy days or in winter when the water temperature is insufficient, the electric heating tube starts and heats to the set temperature through electric energy.
High-efficiency electric heating element meant to complement solar water heating systems guarantees consistent hot water supply even under low sunlight or overcast conditions.

Instant electric water heater heating elements
The core of the instant electric water heater is the integrated heating module (heating body), which is composed of a high-power heating tube (nickel-chromium alloy or copper tube), a fin/flow channel structure and a temperature control system, which heats the water flowing through it in a short time with high power.
Technical highlights:
Power 6000-12000W (far exceeding the water storage type), it is necessary to match independent wires of more than 4 square millimeters and leakage protection devices to ensure electricity safety; the heating tube is physically isolated from the water flow channel (such as the insulation layer of the copper tube jacket) to avoid the risk of leakage; the built-in temperature sensor and electronic temperature control chip can adjust the heating power in real time (such as automatically reducing the power when the water temperature is too high) to prevent dry burning or scalding;
