Solar Water Heater (Evacuated Tube)
Our solar water heater with internal coil, which applies the latest ''KRD-Winding-pipes technology'' and developed by several international well-known energy research professionals of USA Yu Kun Bei Solar Energy Using Research Institution based on KRD technology, improve the disadvantages of traditional solar water heater such as limited heat water, small water output, taking time to heat and worse water quality, etc and successfully develop the technology of ¡°secondary heat exchange¡±, which can integrate high temperature, high efficiency with fast circulation of heat water perfectly. The product is in the cutting edge of solar application industry.
There is heat exchange winding pipe in the unpressurized water tank. The water in water tank can freely exchange with the water in heat collector, while the bath water will exchange with the heater water in water tank through the winding pipe,
The coper and winding pipe increase the costs, but bring stronger heat exchange ability. The temperature of water tank and heat exchange area of winding pipe can be adjusted to keep the continued bath requirement
