evacuated tube solar water heater - JNQG

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.
