The water supply valve can be connected to the aluminum-plastic pipe of the same size. But in terms of service life, it is recommended to use PEX pipes from the downpipe of the solar water heater to the water supply valve. The price of ordinary PEX pipes is about one yuan per meter, and thickened and low temperature resistant ones are lower. more than two yuan per meter. Compared with aluminum plastic pipes, PEX pipes can withstand temperatures from 110 degrees to minus 20 degrees, and their service life is much longer than that of aluminum-plastic pipes. Please accept it, thank you.
Yes.
From an installation point of view. Aluminum-plastic pipes are more convenient to install. The inner diameter of aluminum-plastic pipes is small. Generally, solar power is installed using 1216. During use, there is less cold water and moreuse hot water.
It is easy to maintain and does not require professional tools.
ppr typically uses 20 and requires professional tools for installation. Aluminum-plastic pipes are tight, so there is a greater chance of loosening and leaking during use. The PPR is welded and there are virtually no leaks. In terms of cost of use, high-quality aluminum-plastic pipes are much more expensive than PPR.
In terms of service life, the service life of high-quality aluminum-plastic pipes can completely guarantee that there will be no problems at the end of the heater's service life. solar water. However, the products on the market are now mixed, and the prices of many pipes are very low, so the quality is naturally not guaranteed, not only aluminum-plastic pipes but also ppr.
