It requires a small amount of electricity to keep the pilot light burning, but it can still provide hot water even if the power goes out.
  2. Electronic Ignition: Electronic ignition gas water heaters use a spark to ignite the burner, which means they require electricity to operate. However, some models have a battery backup that allows them to continue functioning during a power outage.
  3. Power Vent: Power vent water heaters use a fan to push exhaust gases out of the flue, which requires electricity to operate. If the power goes out, these types of water heaters will not work.
