It's very rare to have a gas hot water heater that requires electricity.
Similarly with gas ranges, you may need to manually light it, but the valves are usually manual (the oven is a different story).

Same goes for gas fireplaces that do not have a standing pilot and electrically actuated valves, which many newer appliances have.
It's not all that rare these days in cheap condo units (heck, even SFH...) in large cities to require power vent water heaters due to simply horrible architecture imo. Chimneys may not be a thing in some buildings, and locations of utility closets seem not optimized for venting at all.
A surprising number of gas appliances are slowly requiring electricity to run. I wonder if it's even possible to buy a gas clothes dryer these days without electronic controls without going through hoops? Certainly a fraction of the market.
Modern safety standards also drive "cop out" solutions to them like electronic interlocks with stovetops. I wonder how many modern gas stoves actually function without the A/C plugged in? Think I'll actually test this with my two units tonight!
