How it works
The design of this type uses the all-glass evacuated solar collector tubes as the heat absorb element. The high vacuum degree of the clearance between the outer and inner tube can reduce the heat emission which caused by convection and conduction to a very low level. All-glass evacuated tube transfers sun energy into heat energy by high absorption rate and low emittance rate of layer films. Depend on the different density between the hot water and the cold water, a cycle created in the tube which hot water ascending and cold water descending status. Keeping natural circulation like this, the water in the tank will be heated.



non-pressure solar hot water heater for family

It is one of the most common used solar water heating system for household, hotel, hospital, project application etc. It has simple structure and working principle but is the most economical.
It is easy to be installed on the roof to get enough water flow pressure, because the compact system is non-pressurized, water flow depending on gravity water head. This system matched with vacuum tube solar collector. Water flow inside and complete a circulation on it own without given pressure, that is how the name comes from.

1. It takes advantage of the tap water’s pressure. More pressure more comfortable. 


2. The water is heated in short time and meeting your demand for hot water. 


3. It can produce more hot water than the general types with continuous hot water coming.
