Working introduction:

Direct-plug solar water heater uses the vacuum collector's high solar absorption rate and the low emission rate coating, transforms the solar energy it absorbs to the heat energy. It uses the features that the cold water density is bigger than the hot water, forms the circulation that the cold water flows from top to bottom while the hot water flows from bottom to top in the vacuum heat collector,and through such circulation, the water temperature elevate gradually in the water tank.

Introduction:

This model is not pressurized,its advantage is the most popular, economic and classical product in international market,but it works only because of natural circulation,so the press is small.
