Energy saved with a 2025 heat pump during winter driving?

[Jimrpa]

My issue is that at 40 and below the car cannot even produce warm air when in motion. I don't even turn the heater on at that point.

So if the heat pump can actually warm the car, I'd call that a win even if the range is still terrible...

My car has no problems keeping the cabin toasty below 40, or 30, or 20 ?

For a variety of reasons, Ford will only officially give out EPA or WLTP range numbers. In those test conditions, the heat pump won't make any difference. In the real world, the range improvement will be dependent on the outside temperature, making it hard to give it a specific number. 20 miles of added range in the sweet spot seems reasonable; I'm guessing that is in the 30-45 F temperature range. Here in central Ohio, much of winter is right in that range, so this would be a nice benefit to me. I might have to look into this when my options contract is up in July.

If your drive is in the teens (F) or below, there will probably be no difference related to the heat pump. But there still could be a range increase due to other changes that Ford has made.

My home heat pump puts out more BTUs for less electricity than my electric furnace. It uses a lot less energy to heat the home. It paid for itself in 2 years in savings.

So there is a large benefit when outside temps are in a compatible range. Mine still puts out heat when cold, but the air coming out becomes less hot. I found at -8C (17F), its luke warm, and the outside unit goes into a defrost cycle more often. The house begins to feel cool, and the colder it gets, the more often the main furnace kicks in to supplement.

So its not the heat pump gives up, it just cant extract enough heat.

Not a complaint, as it does a great job overall in my zone, which is typically above 0C the majority of the winter, esp. in the daytime. Were it cooler as in other areas of the province, it would be useless.

I have to believe a backup heater element would be necessary, and come on a lot on colder days, negating the benefit on those days. Overall, it would be an asset.

Talking about the heat pump starts @ 7:55 into the video

he says it has the largest benefit 10-40 Fahrenheit and over 85 Fahrenheit

Over 85??

Are they claiming this heat pump is more efficient at cooling than our old AC units?

It’s magic! It also eliminates the need for a frunk!

Yes, I would expect it to be more efficient at higher temps because of the larger condenser coil they stuffed under the frunk. Making the coils bigger improves efficiency because you can get additional subcooling without added compressor pressure ratio.

Same here, it has kept me plenty warm at 25 degrees (coldest so far this season).

might also be related to the 5kW heater in the 21-22 and 1st 23 vehicles. Afterwards a 7kW heater and new loop was installe3d making it easier to heat the cabin and maintain battery temperature.

If the heat-pump is struggling to keep the house warm at -8C it sounds like you have some insulation issues, or a leaky house and/or ductwork. A properly installed cold-climate heat pump should keep your house very comfy at only -8C. Though the constant defrost cycles could be a sign of not enough refrigerant.

You should have the car locked at. Just today it was 29 out and we had to turn the heat off as it was VERY warm in the car.

If I remember correctly - my 21 Premium AWD to precondition in winter took 18 amps ( heating) and took 8 amps to cool in summer. If the heat pump is the same draw as the AC compressor those #’s should be a rough representation of the savings. I am sure there a lot of variables that could significantly change those #’s.

I'm surprised they would tear up the lease. I wonder what they get out of doing that.

They aren't going to just tear it up. They will take it back early and roll any equity, negative or positive, into the new lease.

Not sure if you already know, but the vehicle is equipped with automatic temperature control. You can specify a desired cabin temperature, select “Auto” and the climate control system will maintain the cabin at that temperature.

In very bitter cold, the vehicles with the 5kW heater might suffer if the battery pack needs warmth to operate better.

Yeah, it was so hot that we were fine with it off and just using the seat warmers. It was just an example that if working properly, I think his car should be able to warm the cabin below 40.
