Especially, in the morning hours when everyone is in a rush to leave for the workplace. But the fact is quite opposite. Keeping the geyser switched on for long may lead to geyser problems. The geysers, these days, are quite advanced and can heat the water in just a few minutes. Hence, you can put it on for only 5 minutes before you need the hot water shower. Switching on the water heater before half an hour may cause damage to the heating elements in modern water heaters. Hence, follow this water heater maintenance tip to add some years to your water heater.
