In 2023, there were 131.43 million households in the United States.
That’d be a 17.5% marketshare for gas heating, and a 38% marketshare for gas stoves, but the gas heaters are also going to use a lot more gas than gas stoves do. I’d be pretty comfortable saying that a gas heater will average considerably more than twice as much gas as a stove.
Most stoves in the US are not gas; it’s not an “all stoves versus a subset of heaters” sort of situation.
