Electric geysers offer safety advantages over gas geysers. These provide features such as thermostat, thermal cutoff, and earth leakage protection. They also require less maintenance. But if installed without proper earthing, MCB or RCCB, the risk of shock increases. Plumbing problems such as faulty wiring, low-quality geysers, and missing pressure valves or mixing taps can also be fatal. So, always choose a reputable and licensed installation company.
