When I was a lad in New England, our gas stove heated our house when electrical outages killed the oil furnace during winter storms.
yessir.
When our power went out during storms when I was a kid, my grandmother just lit the stove up with a match and the pilot.
(Can you still do that with modern gas ranges/ovens???)
All that needed to be done was the heating oil tank be 2-3 feet in elevation above the furnace fire box. Nothing would then stop lighting a nice furnace fire! Never had problems in MN winters decades ago.
We had a real bad ice storm here about ten or so years ago. 4 inches over everything! Power out! But we were on natural gas and still kept warm.
Our camper trailer blew up with us inside in 1956. Burned mom, missed me. We were using wellhead gas with no odorant in it. You would think I hate Nat gas but I don’t.
During the Feb 14 1968 storm that shut down The Tulsa area my wife’s folks had total electricity and had to suffer for almost two weeks.
The house I bought years later was total electricity. I did everything I could to get the gas company to run a line to our house. Finally got it! First time our house was ever warm!
