Product Description

 It is one of the most common used solar water heating systems for household,hotel,hospital,project application etc.It has simple structurer 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, which is how the name comes from.

Advantages

 1. Simple structure and working principle

2.Inner tank  are welded by argon arc strictly,so the quality is guaranteed.

 

3.The backet and vacuum tube are adustable,so power bearing is average.

 

4.Non-pressurized,take advantage of tap waters' pressure

Working Principle
