Techhnical Characteristics:

• Pre-heated solar water heater is a new product, it combines the advantages of Non-pressure solar water heater and Separated pressurized solar water heater together. Frankly speaking, the system is put a copper coil inside the Non-pressure solar water heater water tank, this product improves the problems of traditional solar water heater as limited hot water volume, long heat time, few out water, the worse water quality and so on. The “twice heat exchange” technology makes the high temperature, high efficiency and fast & large amount hot water circulation come true.

• Firstly, vacuum tube collector absorbs heat energy of sunshine irradiance to heat the water in the storage tank, the system can bear certain amount of pressure thus the running water can directly connect with the inlet, when opening the valve,cold water flow through the inlet and then to the cooper coil, the hot water inside the water tank play the role as hot resource and do heat exchange via cooper coil with the cold running water, during this process the cold running water been heated to hot water. When cold water flow through the copper coil, its temperature been raised gradully,finally the outlet water is hot water (the temperature maybe ≤ 5°C lower than the hot water in the water tank).
