Solar heating belts cannot be turned on frequently.
The most commonly used solar electric heating tape is 220 V AC. Excessive use of the solar heating tape will increase the temperature of the heating tape, which may cause fire and other dangerous hazards. This will affect and shorten the service life. The solar electric heater temperature setting is not suitable to be plugged in for a long time. It determines the automatic opening and closing of electric heating energy through temperature adjustment.
Therefore, in order not to affect the service life, the solar heating belt cannot be powered on frequently.
It is recommended to turn off and cut off the power supply if it is not used for a long time. It mainly plays the role of compensating the heat dissipation of hot water in the canalization and prevent the water in the pipe from freezing (when the temperature is below zero).
Detailed information:
Advantages of heating tape:
1. the pipeline is uniform, it will not overheat, is safe and reliable; during intermittent operation, the temperature rises and starts quickly; installation and operating costs are simple;
2. is convenient for automatic management; no environmental pollution.
Precautions for use:
1. The maximum length of the solar heating belt is related to the size of the load and the cross-sectional size of the conductive core of the heating belt. the pipe length exceeds 10m, heat tracing should be referred to the design manual for thermal design selection to avoid misuse.
2. The rear end of the heating tape should be madee of a flame-retardant heat-shrinkable tube which has been cross-linked by irradiation. If electrical tape is used, it will cause a short circuit over time. Special heating tapes for solar water heaters are provided to users.
