The solar defrost takes about 30 minutes to enter the water. Typically, it takes 15-30 minutes for the heating tape to thaw. When you start the heating tape, turn on the hot water faucet. Once the hot water tap is out, turn off the heating tape. of the heating tape is 70 degrees and the power is 25 watts per meter. The longest duration is only 2 hours.
If there is still no water in the water after 2 hours, it means the heating tape is broken and the insulation is not working. Or the external insulation has fallen off, exposing a water pipe. Go up to the roof and see if the place where the water outlet at the bottom of the water tank connects to the upper and lower water pipes is exposed. If the insulation falls off, simply rewrap it again. There is no need to replace the heating tape.
Advantages of solar energy
1 Universal, the sun shines on the earth and has no geographical area. Restrictions exist everywhere, whether on land or in the sea, on mountains or islands. They can be directly developed and used, easy to collect, and do not require mining or transportation.
2. It is harmless. The development and use of solar energy will not pollute the environment. It is one of the cleanest sources of energy today, while environmental pollution is becoming more and more serious.
3. Huge. The energy from solar radiation that reaches the Earth's surface each year is equivalent to approximately 130 trillion tons of coal. Its total quantity is the largest energy that can be developed in the world today.
4. For a long time, according to estimates of the rate of nuclear energy produced by the sun, hydrogen storage is sufficient to last for tensnes billions of years, and the lifespan of the Earth is also about several billion years. In this sense, we can say that the energy of the sun is inexhaustible.
