Non-pressurized solar water heater without assistant tank
How solar water heater system works
1. Solar water heater system of all glass evacuated tube collector integrated with storage tank, are ideal for use in houses and other applications where cheap, reliable hot water supply is required. They are simple, economic and practical.
2. As the specific gravities of hot water and cold water are different, cold water goes downward and hot water goes upward.
3. When cold water in evacuated tubes is heated, it becomes lighter and goes to the water tank, while cold water the tank goes down to the evacuated tubes
4. Through this circulation, the cold water in the water tank will be gradually heated.
Solar Water Heater System Features:
1. Cheap and reliable solution, Simple structure, Easy installation
2. Withstands water pressure no more than 0.1MPa
3. Electric heater can be used as back up in rainy days
4. Hot water can be used directly, or can be used as a pre-heated
This type uses all-glasses evacuated tubes as the solar collector for absorbing solar energy and transferring it into heat energy. As the different densities of hot water and cold water, the hot water flows automatically upwards while the cold water flows down. The water flowing cycle is created in the tube. And the water in the storage tank is heated from this natural circulation. The hot water pressure of this non-pressure system is from the gravity, so it should be installed on the roof or at least 3-4 meters higher than hot water tap. Or you can install a booster pump to get stronger outlet hot water
