I wonder who the fuck is downvoting these comments. LOL - "NO FOSSIL FUELS, YOU MUST DIE IN A POWER OUTAGE!"

Maybe its not because of assholes? Maybe its because the comment is objectively wrong?

Neither my gas water heater, or gas furnace work during a power outage. As another commenter said they both have electronic controls.

Yes, and a gas generator or a remarkably small battery and inverter/dc-dc transformer overcomes the obstacle of powering the electronics - no need for a powerwall. Or you can have a woodstove - not fossil fuels, but def burning carbon for heat.

Most gas furnaces use forced air blowers to distribute the heat. You're not running that on a small battery.

I was thinking about the water heater and radiators, totally forgot forced air blowers - you're right.

Here in Canada it's common to use geothermal heat pumps with floor heating. Even in a power outage the floor will retain their heat for much longer than conventional heating system can.

And if worst comes to worst, it's not hard to run them off a generator, although I've never known anyone who has ever needed to.

My gas fireplace works great in a power outage, as do my stove and grill. Just because a subset of gas-powered appliances don't work doesn't mean none of them work.
