1.Cost effective solar water heating solution
The equipment offers a low maintenance and repair cost, while also providing a long operating life.
3.Short amortization rate
4.Customized solar water hating solutions.
The use of evacuated tubes and PU insulation in solar energy systems ensures that there is minimal heat loss and a high energy yield. This is primarily due to the high vacuum present in the evacuated tubes, which helps to maintain optimal heat transfer efficiency. Additionally, the PU insulation further contributes to reducing heat loss, resulting in a more efficient and effective solar energy solution.
The inner tank is made of top-notch stainless steel, ensuring a consistent maintenance of excellent water quality.

Working Principle Of Solar Water Heater

The solar water heater, known as a thermosyphon low-pressure solar geyser, operates on a simple thermal circulation principle. First, solar vacuum tubes heat the cold water, causing it to rise up into the tank. As a result, the cold water in the tank flows back into the solar vacuum tubes, creating a natural circulation known as thermosyphon. This process continues, gradually heating the entire tank of water.
