At present the photoelectric complementary hot water supply system in the form of integral and red-tipped two kinds. Integral is currently on the market photoelectric complementary type. By solar water heaters and red-tipped is indoor tandem combination becomes. Photoelectric complementary hot water supply system in use existing this many potential safety problems.
Ground caused due to make water heater charged users of electric shock accidents taking place repeatedly, the reason is: install electric water heater thing grounding system is not good, even lack, such as faulty line, line aging, private pull wire, use inferior switch socket, used pipe when grounding wires and so on, these may lead to landlines charged, causing electric shock accidents.
Install unstable because electric water heater installation fixed unreliable not drop, users hit into injury accidents occur frequently. The reason is not installed firmly fixed expansion and wall body connection isn't firm, or the wall itself of low intensity, and cannot be fixed expansion bolt.
Line open-air Ming apply risk factors for solar water heater much more because residents after be being installed,
solar water heater pipe and wire are set in the wall outside Ming, exactly suspended in the wall outside. This installation way has the following problems: heat preservation effect is poor, winter easy freeze jams pipeline, and even damage pipe DongLie, melts to adjacent inside ooze water; etc. Wire suffer wind blowing rain, aging leakage, Because no on fixed measures, easily blown broken cause charged the be born by others electrocuted.
