Our tankless solar water heater also called Integral vacuum tube solar collector,which is made of 137mm large-diameter vacuum tube.As its name suggests,in an integral vacuum tube collector storage system,the collector and tank are combined into one single unit .Because the diameter of solar vacuum tube is very big.So it works not only as a solar collector, but also a water storage tank.So the household tap water is heated and stored within the combined heat storage and collection unit.

There is a stainless steel tank inside the solar vacuum tube ,which guarantees the security and efficiency .Because the water is stored in the stainless steel tank and there is no water in the vacuum tube, so it has the characteristics of high pressure resistance, strong impact resistance, high safety performance, less heat loss, no scaling, and more convenient use.

As soon as the hot water been used,the cold water enters into the solar vacuum tube instantly and been heated by solar energy immediately.So the tankless solar water heater is high efficiency .
