Does my hot water heater work when the power is out? I have natural gas to heat the heater but I am wondering if it also needs electricity to run. We lost power and the water was still hot days after losing power. Was the water still hot from when we had power or does the heater still work without power? 1 following.
Tank-style electric water heaters use two heating elements to warm the water, one at the bottom and one nearer the top. Power surges, mineral build-up and age can cause either element to fail or burn out. If your water heater produces only lukewarm water, suspect a bad top element. If it produces hot water in short supply, the probable cause is a bad bottom element. Test both to be certain. Follow these steps to check the heating elements in a hot water heater.
