Proper maintenance and cleaning of water heater electric heating pipes is also a necessary factor to improve life!
The water heater electric heating pipe is considered from the following points:
1. Input power supply, the voltage should not exceed 10% of the rated voltage on various electric heating tubes. If it is lower than the rated voltage, the heat generated by the electric heating tube will also decrease.
2, the selection of electric heating tube should pay special attention to the heating medium. It should not corrode the electric heating shell material.
3. For the heat pipe terminal, use 2 nuts to be relatively fastened during wiring. Do not use excessive force to avoid loosening the screw and damage the electric heating tube.
4. The special electric heating tube should be read in detail before installation and use to avoid damage.
5, should be stored in a dry warehouse, if the surface is damp due to long-term placement, the insulation resistance is measured using the application of a megohmmeter. If it is less than 1 megohm / 500 volts, the electric heating tube should be placed in a 200 degree drying oven for drying.
6.The water heater electric heating pipe is used for a long time. If the surface gathers thick pipe scale, it should be cleaned regularly. Otherwise, the heat transfer performance of the water heater electric heating pipe will be reduced and the heat load on the pipe surface will exceed the rated allowable damage.
