Vacuum Tube Solar Water Heater | ESCOO
Solar Evacuated Tubes - Solar Vacuum Tubes. When investing in solar water heaters, it is important to ensure the "engine" you select is the most powerful and the longest lasting made. This if why we use SunRain's patented "3-Hi" solar vacuum tubes. The absorbing coating found on the inner layer determines how efficient the vacuum tube will operate.
The inner glass tube is coated with a patented 3-layer process of copper, aluminum and aluminum/Nitrogen layer. It is these selective coatings that are responsible for the performance of the tube as they absorb and transfer the suns heat radiation. Because there is a vacuum in between the heat cannot escape back out making these tubes 97% efficient.
Vacuum tube solar water heaters are made up of all-glass evacuated solar collector tubes which have function to change the solar energy to heat energy, storage water tank, stand and interrelated accessories. It is well-known that the temperature of the surface facing sun is high, while the other surface is low. So that water in the tubes has different temperature, and the warmer water rises while …
How Does A Vacuum Hot Water Boiler Work--ZBG
Vacuum hot water boiler is absolutely safe and is praised as the boiler without explosion forever because it operates in the negative pressure. During the operation process of the boiler, the hot media (water in boiler) doesn't make any change; it only stays in the vacuum chamber and transfers heat between heat-exchanging tube and heat exchanger.
