Oxford study proves heat pumps triumph over fossil fuels in the cold

This is a most excellent place for technology news and articles.
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.
