(1) Damage to the stainless steel electric heating tube of the water heater
The heater element withstand voltage is lower than the standard value, the leakage current is greater than 5mA or the insulation current is less than 1MΩ, and it is unrecoverable.
(2) The outer casing has flame emission and melt, severe corrosion on the surface or other damage that is not allowed to be repaired.
The actual power of the heating element is 20% worse than the rated power.
The water heater stainless steel electric heating tube is an electrical component that converts electrical energy into heat energy. Because of its low price, convenient use, convenient installation and no pollution, it is widely used in various electric heating occasions.
