1.Description of Changzhou Sunfield 24tubes non-pressurized solar water heating

Thermosyphon solar water heater (compact non-pressurized system) is comprised of three parts: water tank, vacuum tubes (collector), and support (bracket). Working principle: Non-pressure solar heating is a kind of solar water heating systems that the bellow collector directly connects with the above water tank. This solar water heater do not need to run the pump to force and do not require pipeline connections between the collector and the water tank. It is a simple and secure way to collect solar energy. The working principle of solar water heater is to make a natural circulation between the water tank and the collector.     2.How it worksa. The high quality vacuum tubes absorb the solar ray to heat the cold water in the vacuum tube. b. The hot water rises in the top of the water tank from the vacuum tubes, and the cold water from the water tank sinks to the vacuum tubes to be heated by solar collector. So the whole system is always circulating continuously. c. You can use a controller or an auxiliary tank to let the water fill the water tank automatically.3.Features of  Changzhou Sunfield 24 tubes non-pressurized solar water heating :  1. Lowest price. Most family can afford it. 2. Highest efficiency. The water fills the whole system, so that the heat loss is the least. 3. There is no need to wait and the hot water is available immediately. 4. SUS304-2B food grade stainless steel inner tank keeps the water quality. anti-corrosion feature 5. SUS304-2B food grade stainless steel outer tank makes the tank look shinning.4.Specifications of Changzhou Sunfield 24 tubes non-pressurized solar water heating :
