1, solar water heater water tank leakage - dust ring aging under normal circumstances, open type solar water heater water storage tank must reserve more than 2 vents, to ensure that the water tank and the atmosphere pass, to prevent the occurrence of negative pressure or positive pressure caused by the water tank Suck or burst. When the water tank is installed, the exhausting measures usually use upper exhaust, side exhaust or lower exhaust. Installed on the top of the water storage tank is the upper exhaust pipe. The upper exhaust pipe is generally composed of a venting cap, a dustproof ring and a sealing ring. After installing for about half a year, the dustproof ring will be aging. In this way, when the water vapor in the water storage tank is discharged from the water tank, the cold air outside will become water droplets, and the exhaust pipe will flow down through the dustproof ring to enter the water tank insulation layer. Similarly, in rainy weather, the rain will also Follow the dust ring to enter the insulation.
2, solar water heater water tank leakage - overflow tube is short in the solar water heater installation water storage tank at the bottom of the water tank installed solar water heater installation under the overflow pipe, the lower overflow pipe can play the water tank water overflow pipe back water prompt The role of the atmosphere. Some manufacturers use integrated solar overflow pipes, as well as split-type overflow pipes for solar energy. The most common water leakage phenomenon of the lower overflow pipe is that the overflow pipe is short, the water level in the water storage tank does not reach the highest point, and the water in the overflow pipe returns, resulting in a low water level in the water storage tank. Under normal conditions of solar light, some of the hot water leaks through the overflow pipe due to the thermal expansion and contraction of the water in the water storage tank. If the temperature controller is used to automatically control the water supply, it will cause the problem of the water supply and the temperature of the water tank.
3, solar water heater water tank leakage - improper maintenance In general, most manufacturers of solar water heaters reserve solar water heaters electric heating holes at the bottom of the water tank, at the factory will use solar water heaters electric heating plugs for sealing. The solar water heater installation workers decide whether to install the solar water heater electric heating according to the user's needs during installation. If the user needs to install the solar water heater electric heating, the solar water heater installation worker will remove the electric heating plug and install the solar water heater to heat the electric heater. In fact, it was a very simple thing, but it often caused the water tank to leak or even be scrapped due to installation and maintenance.
