      That’s how all hot water heaters work. His just uses natural gas instead of electricity.

          Not if it’s a tank system. They can, but they don’t have to, since the pilot stays lit all the time. A tankless system has to use some power since it cycles every time you use it.

          Some use a 9v battery on their starter.

          Regardless, you can just use a match if you want to.

          In either case, they don’t require mains power.

          (Sure, there are different models, etc. but it’s not a requirement that all have an electric start, or a mains electric start)
