Nature provides us liberal amounts of energy.The sun is just one source.Solar water heater collect the energy from the sun to heat air or a fluid. The air or fluid then transfers solar heat directly or indirectly to your water supply. Solar water heating technologies are a simple, reliable, and cost-effective method of harnessing the sun's energy to provide for the energy needs of homes.





PEX stands for cross-linked polyethylene or XLPEl. PEX is commonly used for hot and cold water in homes, and for hydronic heating systems (such as radiant under-floor systems) due to its resistance to hot and cold temperatures. PEX is widely used now for its competitive pricing, ease of use, and the long rolls of piping that it can come in. PEX can be joined in many different ways including push-fit fittings and specialty PEX tools used with crimp rings to secure the joints. 

PAP pipe, also known as Perforated Aluminum Pipe,or PEX-AL-PEX pipe. is a five layer pipe composed of plastic, adhesive and aluminum.PAP pipes have expansion properties similar to copper.

Advantages: the price is cheaper, can be arbitrary curved bow, smooth surface, construction is convenient.

Disadvantages: easy to aging, the use of hidden trouble is much, use fixed number of year is short, the practice has proved that in the use of a year later, the pipe joint leakage phenomenon appear easily.


PPR Pipe,Pipe made of Polypropylene Random Copolymer (Polypropylene Random)

As a new type of pipe material, PPR pipe has a unique advantage.It can be used as a cold water pipe, hot water pipes can also be used.PPR pipe interface with hot-melt technology, fully integrated between the tubes together.

Advantage:moderate price, stable performance, heat insulation, corrosion resistance, smooth inner wall, safe and reliable, does not penetrate, use fixed number of year can be up to 50 years.

Disadvantages:the construction technical requirements higher, need to use special tools and professionals to undertake construction in order to ensure system safety.


Stainless steel pipe is an expensive material for piping, especially since copper is a much more appropriate choice. One beneficial characteristic is that stainless steel is better able to withstand the corrosive nature of salt water over other pipes, and it is often used in marine environments for that reason.


With the improvement of people living standard and the consciousness of environmental protection, safe and green  pipes is more and more popular for people and society.Composite pipes, have both the advantage of metal and plastic, because of different expansion coefficient of them, long-term use lead to pipe layer cause hidden trouble;Plastic tubing ,best insulation in all of pipes, because of its main ingredients is polymer and  may be toxicity, if used in direct drinking and will cause harm to human body.Stainless steel is the first selection used in plumping pipes of solar water heater because of its high strength, corrosion resistance, smooth and delicate appearance, tort health and long life.The birth of the thin-wall stainless steel tubes have created favorable conditions for the stainless steel to enter residential market.In recent years, with the elegant appearance and excellent performance, stainless steel pipe will be a final development trend for solar water heater.
