How to choose a solar water heater

1. Check the craftsmanship. Solar water heaters need to be used frequently. If the workmanship is not good, it is easy to leak. Therefore, when purchasing, you should carefully check the various interfaces of the solar water heater.

2. Check the weight of the vacuum tube. High-quality vacuum tubes weigh more than 100 grams than ordinary vacuum tubes. You can feel it clearly by weighing it with your hand. This is directly related to its material and thickness. Even if the same interference coating technology is used, insufficient film thickness, insufficient outer wall thickness and excessive metal ion content will also affect the quality of the tube.

3. Look at the thermal performance indicators of the product. The thermal performance indicators that are closely related to the interests of consumers are the average thermal efficiency and average heat loss coefficient of solar water heaters. These two indicators are key indexes that determine the heat collection and heat preservation capabilities of solar water heaters. Generally speaking, the higher the average thermal efficiency, the higher the heat collection capacity of the product; and the lower the average heat loss coefficient, the stronger the heat storage and heat preservation capacity of the product.

4. Check whether the water heater meets the national standards. When choosing any solar water heater, we must look at the information in it. This is mainly to see whether the solar water heater meets the national standards. We must also look at the qualifications of the merchant, because the solar water heater market is very chaotic now, and we must pay attention.

How to clean a solar water heater

1. Remove the sealing ring and use a plum blossom screwdriver to slowly remove it.

2. Dismantling the solar tube is laborious due to rust over the years. Please remove it slowly and carefully. If possible, wear gloves to prevent scratches.

3. Pour out the waste water and dirt in the pipe, clean the scale with a slightly blunt tool, pay attention to protecting the inner tank, and use plenty of clean water to clean the scale.

4. Apply a little diluted detergent on the top of the solar tube and carefully reinstall the solar tube.

How to use solar water heater

1. First, we find the power switch of the solar water heater (it is best to turn off the power switch after each use of the solar water heater. This is not only energy-saving, but also safer. Safety is more important and should be formed into a habit).

2. Find the switch of the water heater and the main valve, and open them (just pull the water heater switch and the main valve upwards, it is quite simple).

3. Then the temperature setting meter of the solar water heater lights up (it is the dial above).

4. Then we will see a set temperature, which is the highest temperature you want to set, which is the temperature you need when taking a bath.

5. There is an up and down button, which is used to set the temperature. Up means increasing the temperature, and down means decreasing the temperature.

6. Then click on the instant heating button to start boiling water using the stored solar energy. It will take a few minutes for the water to start heating up.

7. You can take a shower when the actual temperature is consistent with the set temperature. Of course, you can also measure it with your hands and take a shower if you think it is appropriate.
