As long as it is a special solar pipe, it is a PEX pipe. Solar power produced by regular manufacturers (such as Huangming) has dedicated pipes marked by its own manufacturer (the upper and lower water pipes installed by Huangming have "Huangming Solar" special "words"). The quality of this type of pipe is guaranteed and even if there is a problem (water pipe break, frost crack, deformation due to hot water), the manufacturer will pay the claim. Unlike some manufacturers, they guarantee the product when you buy it and accept no responsibility in the event of breakage. Actually, for a small problem, you have to pay 30 or 50 yuan, and if the water leaks and the upstairs or downstairs is flooded, you have to pay 8,000 or 10,000 yuan. The manufacturer is like any other. person, acting like a thug, and you don't have to pay. The solution is to say it's not their pipeline and they are not responsiblecompensation. Huang Ming can't do anything without compensation. Not only the pipes, but also all the installed copper fittings have the word Huang Ming on them. They also take the initiative to compensate for water leaks. After all, the reputation of the product is at stake. more important than anything else. Plus, big brands rarely break. Try not to use aluminum-plastic pipes. There are many poor quality, peeling and leaking pipes that are not suitable for solar energy.
What is the best pipe to use to connect the solar hot water connection pipe to domestic water?
Nowadays, PEX pipes or aluminum-plastic pipes are more commonly used for solar water heaters.
PVC is generally used on non-pressure cold water pipes and should not be used on solar water heaters, otherwise water leaks may occur.will occur frequently during repairs.
PEX pipes have relatively good frost resistance, but they are easily oxidized and become brittle when exposed to sunlight, so the external insulation of the pipes must be good to avoid so that they do not crack due to the sun.
Aluminum-plastic pipes have poorer frost resistance, but if the pipe's insulation cracks, its oxidation resistance is better than that of PEX pipes.
Pipes are plastic products subject to bad weather and particularly brittle when exposed to sunlight. Additionally, pipes often alternate between hot and cold water, which is more likely to shorten their lifespan.
When resellers sell solar, the retail price primarily includes installation and material costs. Customers also hope that the price is cheap and the installation isin place. Some dealers factor in the cost of installation hardware during installation. solar energy for customers. Cost, often using average quality products and not taking sun protection measures, resulting in pipeline damage. Customers are recommended not to consider a temporary cheap price when purchasing solar power, which will cause after-sales problems. the future.
You can consider using normal PVC water pipe to connect it to solar energy in one step, and then make the necessary insulation and sunscreen materials. In this way, the lifespan of the pipe will be greatly improved. improved and after-sales problems will be reduced. Of course, the cost will also be reduced, depending on the wishes of consumers.
Cleaning and maintenance A solar water heater is a device that uses solar energy to heat water.water from low temperature to high temperature. Solar water heaters have become an indispensable part of people's lives due to their time, electricity and energy saving features.

Should solar sewer pipes use PEX pipes or aluminum-plastic pipes to resist freezing in winter?
PEX pipes for solar hot water
The advantages are: 1. Resistance to hot and cold shock, from -70 degrees to 110 degrees
2. energy to mixed water The valve is connected to a pipe, without pipe connections in the middle, so there is no leakage or dripping in the middle
PPR for domestic water< /p>
The advantage is: the pipe is relatively hard, plus the elbows and other connecting parts. Finally, it can be manufactured horizontally and verticallyement, and beautiful.
Generally, aluminum-plastic pipes are not used due to their high cost. PEX pipes are used. The exterior of the pipes must be covered with a layer of insulation. I also teach you a trick to use it under solar energy. Install a 3-way fitting near the water line outlet: 1 solenoid valve, 2. connected to the water line, and 3 connected to atmosphere. In this way, when no water is used in winter, close the solenoid valve, open the indoor faucet and drain the water into the pipe, so that the pipe does not freeze. .
