Nowadays, PEX pipes or aluminum-plastic pipes are more commonly used in 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 will frequently occur 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, the pipes often alternate between hot waterand 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 is in 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 hardThe life 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 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.
