Oxford study proves heat pumps triumph over fossil fuels in the cold::Published Monday in the scientific journal Joule, the research found that heat pumps are two to three times more efficient than their oil and gas counterparts, specifically in temperatures ranging from 10 C to -20 C.
That’s great, but fossil fuels are often available in the event of a power outage, and that can save lives during a winter storm. Availability is just as important as efficiency, and until we can make our power grid more resilient, we need to factor that in.
We’re also going to run out of oil in the next 40-45 years, so we should factor that in.
The 2 times (living not with my parents anymore) I had now electric power unplanned was of course when it was cold. However the fancy central heating running on gas was also not working. As the main unit also needed electric power.
So I could still cook my food but that’s was it. No heat. But that being said in my entire life we lost power (including as a kid) maybe 5 times and only for a couple of hours. In 33 years
I now have a heat pump and for cooking induction. So in a power outage I need to grab some camping gear. But I will probably survive for a couple of hours without heat.
But if you have regular power outages you and everybody in your country should probably vote and make your voices heard. If you live in a country where most people can afford heat pumps, the government can afford fixing the power grid.
Yeah, central air requires power to run the fan, but also the thermostat.
If you want to heat your house during a power outage, it takes less power to run your gas furnace than a space heater.
I have a duel fuel system (heat pump + gas furnace) which, while more expensive, is really the best of both worlds.
In a power outage I can plug in a generator and get the furnace running.
If temps drop too low and the heat pump is struggling I can switch to the furnace.
I can choose which to run based on current energy costs.
When looking into heat pumps everyone told me they don’t work well in the northeast or they would be more expensive to run here. I found it really difficult to get an accurate estimate of the cost difference between running a heat pump vs a gas furnace. Ultimately I decided to go dual fuel for flexibility but after comparing my bills before and after I almost wish I’d gone with a hyper heat unit so it could run at lower outdoor temps because the heat pump has turned out to be cheaper but I can’t run it at low temps.
I think HVAC techs in this area are weary of them based on past experience with older units but they really have improved in recent years.

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.
