2. In order to improve the ability to absorb sunlight, hot water bottles are usually made from black materials.
3. When using hot water indoors, you can use the relationship between flow and pressure to adjust the hot and cold degree of the water.
I am a practitioner of solar water heaters. I don't know if the solar hot water bottle you mentioned is the black plastic bag commonly used in Shandong and other regions.We can go swimming on the roof. If so, it's simple: it is a closed black plastic bag to which two pipes are connected, one for the water inlet and the other for the return signal pipe. 'water. When using, first place the plastic bag on the roof with direct sunlight and use the tap water pipe to fill the plastic bag with water through the water pipes upper and lower. When the water is full, water will flow out of the signal pipe. , and the tap water will be turned off. As the black plastic bag absorbs heat easily, it naturally heats the water inside and can therefore be washed in the evening.
This thing is relatively cheap and can usually be bought for a few dozen yuan. However, since it cannot retain heat, it can only be used in summer, and due to the aging of rubber, it is used. can generally only be usedeu for one year.
