I can only see the outside, I'm not sure what it is. Typically, solar has two pipes, one for the upper and lower water lines and one for the overflow pipe. In the photo, you can see that one of the two pipes at the top is a water supply pipe for solar water supply, and the other is a downstream pipe for hot water supply. The valve on the water supply pipe is closed when water passes through it. The water valve is usually open and the bottom one without a valve is usually used to receive return water (i.e. overflow water after the solar system is filled with water) . ). You need to check, you can't be sure from the above.
Is there a solar water pipe?
In summer, 16 pipes are enough, but in winter, the water consumption is large and three people need of at least 20 pipes. BestWater heater brands include Huangming, Taiyangyu, Tsinghua Sunshine, etc. Huangming is more expensive, but the quality is the best. Solar water heaters come in different capacities and prices, ranging from around 3000 to 4000 for an average household. the brands are between 2000 and 3000.
The solar water supply pipe and the downspout are not actually the same water pipe. One is the water inlet pipe and the other is the water return pipe. The two methods of use and installation are very different. If you do not understand the specific installation method during the initial installation, you will need to find a professional to install and maintain it to ensure normal solar heating effect, and allow you to use hot. water normally every evening, and you also need to clean and clean it regularly.
