    Pre-heat solar water heater

    1. The copper coil inside of the non-pressure tank can bear 0.7MPa during the operation
    2. There is assistant tank which can load the water automatically
    3. The vacuum tube heat the water and supply hot water to the tank, then the water in the copper coil can be heated by the hot water in the water tank
    4. It is pre-heating and heat exchange process

    1. Detailed information


    Working principle

    This system relies on natural circulation, there is copper coil in the water tank, which is used to exchange heat and get hot water, tank just works as boiler, which will supply heat to copper coil, when water goes through copper coil , it will get heat from hot water via copper coil
