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.
Demand water heaters ditch the giant storage tank and instead warm up moderate amounts of water when needed. As water flows through the device, a heating element â either a gas burner or an electrical element â warms it up. As soon as the hot water faucet is turned off, the heating element shuts down. Without a tank of water constantly warming, standby heat loss is eliminated. According to the National Association of Home Builders, tankless systems can cut 10 to 20 percent off your water-heating bill.
