Will a hot water heater work with only one element?
Single element water heaters only have one source of heat located near the bottom of the tank, so it can take a while for the water at the top of the tank to heat up. This can be a problem if you run out of hot water, as you'll have to wait longer for the water near the hot water outlet to warm up.
What causes a hot water element to burn out?
