Considering that solar water pipes must be antifreeze, meaning they cannot freeze and crack under normal circumstances, there are only three pipe materials on the market: true PEX pipes reticulated, PERT pipes and PB pipes.
At present, most of the market uses PEX as solar water pipes, because it is frost-resistant and its price is relatively low. However, over the past couple of years, many manufacturers have reduced their crosslinking. degree a lot in order to compete for the market, so The cost is reduced, but its antifreeze performance is also greatly reduced. If you use it, it is recommended not to choose one with less than 140 yuan. -the freezing performance of PERT is better than that of PEX, but its cost is relatively higher, so it is now very popular in the market. It is rarely usedseated for solar energy and PB pipes should be considered the best antifreeze; on the market. They are now used in many high-end underfloor heating projects. Of course, their costs are higher and they cannot be promoted in the solar energy sector at present.
Therefore, it is recommended to choose higher quality PEX cross-linked pipes, as long as you are not trying to be cheap.
PPR cannot be used as solar water supply and drainage pipes. It can freeze and crack in one winter in the north (it can be used in the south). it does not work.
Aluminum-plastic pipes are not good either. Foshan Rifeng and Jinde used them for only four to five years in the north and south of the Yellow River, and only two or three years in the northeast. .
But indoors, for aesthetic and temperature reasonshigh internal re, PPR or aluminum-plastic pipes can be used.
I hope the above answers are helpful to you.
Solar water heater\x0d\ There are many options for installing water pipes, such as PPR water pipes, copper pipes, copper-plastic pipes (pipes aluminum-plastic), PVC pipes, iron pipes, etc. \x0d\In fact, considering various factors, PPR water pipes are quite ideal. The reason is also very simple. Firstly, the quality of good PPR water pipes is very reliable, which is quite comparable to that of copper pipes. Secondly, the price is more acceptable and much lower than copper pipes; that it is healthy, without any rust or patina. \x0d\Note, the water line must be 6 points. PPR water pipes are divided into cold water pipes and hot water pipes. The key is the thickheart of the pipe wall. It is recommended that everyone use hot water pipes for drainage at home. the price is not much more expensive. \x0d\ Considering that solar water pipes must be antifreeze, meaning they cannot freeze and crack under normal circumstances, there are only three types of pipes on the market: true reticulated pipes PEX, PERT pipes and PB pipes. . \x0d\At present, most of the market uses PEX as solar water pipes, because it is frost-resistant and the price is relatively low. However, over the past couple of years, many manufacturers have significantly reduced their degree of crosslinking. in order to be competitive in the market, thereby reducing costs. But at the same time, its antifreeze performance has also been significantly reduced. If you use it, it is recommended not to choose one that costs less than 140yuan. the anti-freeze performance of PERT is better than that of PEX, but the cost is relatively higher, so it is rarely used for solar energy in the market, and PB pipe should be regarded as the best anti-freeze pipe in the market; walk. Today, many high-end floor heating pipes are used in many projects. Of course, its cost is higher and it cannot be promoted in the solar power industry at present. \x0d\ Therefore, it is recommended to choose higher quality PEX cross-linked pipes, as long as you are not trying to be cheap. \x0d\PPR cannot be used as solar water supply and drainage pipes. It will freeze and crack in one winter in the north (it can be used in the south). \x0d\Aluminum-plastic pipes are no good either. Foshan Rifeng and Jinde used them only four to five years in the north and south of the flYellow river, and only two or three years in the northeast. \x0d\But inside, for the sake of appearance and high indoor temperature, PPR or aluminum-plastic pipes can be used.
