Working Principle of Integrative Non-pressure System:
Kaidun Non- pressure Solar Water Heater is a simple form of making use of solar energy to get hot water. The integrative non-pressure solar water heater directly joints the heat collector with the water tank on the top. There is no need of pump to push the water and no need of pipeline between the collectors and the tank. When the water in the vacuum heat-collecting tube is heated, its density will decrease and will go upward into the tank; meanwhile the cold water in the tank will flow down into the tube due to its greater density. Thus, the circulation and heat-exchanging in the system is completed.

Advantages of Integrative Non-pressure Solar Water Heater:
1. Designed on the heat-receiving conditions of winter;
2. Applies TG-technique to accelerate the flow of water and thicker and denser insulation layer;
3. More durable to the impact from wind, snow and hail;
4. Larger water tank more suitable for family use and hot water center;
5. KAIDUN heat-losing reducing techniques, vacuum tube highly absorptive, highly durable to hot and cold weather conditions;
6. Larger installing angle makes it more suitable for regions of higher altitude and severe climate;
7. Nice shape and finish makes it more harmonious with the surroundings
