    Problem

    Cause

    Solution

    Water keeps cold

    during sunny day

    1.There exists shelter above the heat collector or tubes seriously dirty.
    2.Upper and lower valves are not tightly closed, so the cold water flows in continuously.

    1.Take off the shelter or move the heater awayfrom

    the current location, and clean the tubes.
    2.Changes the valves.

    Water tank cannot reach

    the full level with water flow

    1.The pressure of tap water is not high enough.
    2.water leakage of pipe.
    3.water leakage of tank.

    1.Add a small water pump.
    2.Change the pipe.
    3.Find the solution for leakage of tank.

    Water leakage of tank

    1.Damage of seal ring or was not correctly positioned while assembly.
    2.Crack of the inner layer of tank.

    1.Replace the steal ring or re-position it.
    2.Replace the inner layer of tank with a new one.

    Water is cold one

    minute but not the

    next during taking shower

    The pressure of the tap water is not stable

    Fumish on roof one supplementary water tank

    which can be functional as water storage,

    water pressure stabilizer.

    No hot water supply

    in winter time

    1.Pipe line frozen.
    2.The weather is too cold to heat up the water.
    3.Took no measure to the heat preservation of pipe

    1.Distributor or producer helps do heat

    preservation (not for free).
    2.Evacuate the water in pipe with hot water,

    and refill the water in the morning.
    3.Furnish pipe with an electrical heating strip.
    4.In very cold weather, turn on a little the hot water valve to keep

    a small flow of hot water to avoid freeze of water.
