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.
Your water heater usually has two elements and two thermostats. The upper thermostat has two functions. First it allows the upper element to heat the water in the top of the tank. When this water is hot enough it shuts the upper element off.Then it allows power to go to the lower element.Make sure that the power is off.o light, time for a new thermostat. To check the lower thermostat you need the upper thermostat turned off. The lower thermostat needs to be turned to its highest setting. This should insure that lower thermostat is allowed to engage. Use the water heater tester to check terminals #1 and #2 (the lower set).
