Vacuum Tube Solar Centralized Heating System

the operational theory of the solar energy hot-water engineering:
 
when the cold water flows into the solar energy heat collector, it receives the sunlight and the temperature increases. once it reaches the set temperature, the relevant valves and pumps will open automatically to transfer the hot water into the heat storage tank for reservation. if the temperature of the tank is below the floor temperature, it will make auto temperature difference cycle. if the sunlight is not enough and the solar energy can't produce sufficient temperature, the supplementary heat sources such as electrical heating rod and gas equipment will start automatically to keep the constant temperature and water in the heat storage tank.
 
It supports indoor circulating pipes. in order to improve the water comfort and saves energy consumption, there are 3 kinds of pipe circulation modes in the system, namely timely circulation, fixed temperature circulation and temperature difference circulation. when using the water, all one has to do is to open the water tap.


It has receives several international and national inventions and patents.
It can provide clean hot water for life.
It supplies heat for the communities, residence and buildings.
It is energy-saving and environmentally-friendly.
It brings you huge investment return. 10-year use is equal to 2 sets of the equipment of the same value.
Better, Faster & More Energy-Saving
