Heatpump is the biggest upgrade in Gen 2, imo

[Zoidz]

Yeah, yeah, and if you have a lighter and flatulate you also have a rocket engine that conceptually works like Merlin. Don't act like Elon didn't revolutionize the world.

Sorry you missed this part of my post "It's a creative solution to solving a problem".

Is there a efficiency based on temp ranges for car heat pump. We had moved to heat pump to our house and ended up adding gas furnace; as the company said that I needed it even for moderate NJ weather in the winter.

When did you install this? Hopefully at least five years ago. Modern heat pumps are capable of operating without any furnace support down to about -15 degrees F. Heat pump installs in Maine surpassed the goal of 100,000 by 2025 over a year early! The issue is you have to specify your needs, and the more winter-capable models are more costly. They also don't run as efficiently at lower temperatures, but still beat gas or resistance heat.

I had LG cold-capable heat pumps installed in the Boston area last fall. The house was warm and toasty all winter. The old gas boiler is still connected for hot water and could be used as a backup home heat source in a pinch, but isn't needed. It will be removed once I switch to a heat pump hybrid water heater, maybe next year.

Sorry you missed my sarcasm that was about Elon rather than you.

I actually thought your post was interesting. I suspected the fawning over the "octovalve" was over the top. You provided a very common example of basically the same idea being used elsewhere. Doesn't mean Tesla wasn't smart to port the idea over. Just means the way the cult talked about it was over the top. And ultimately that's what I was snarking over.

Not you, of course! Bots have yet to develop a quirky sense of humor.

Sorry, Whoosh!! Sarcasm went right over my head!!!!

Not a bot but really happy we have another new thread discussing heat pump technology.

It's seems like we haven't had a thread about CarPlay in a couple of weeks, it seems overdue....

- When cooling on a hot day, it has to dump the recovered heat somewhere, which is almost always going to be the atmosphere via an air exchange condensor coil. On hot days, the battery, motors, electronics all may/will need cooling. I seriously doubt they will dump heat INTO the battery on a hot day!

Oh great. Now I have to convert my garage into a drive-in-freezer so I can cold soak my vehicle and test your hypothesis mid-summer.

Oh no..what did I start!!

To answer your original question, in case you don't think you've gotten a serious answer yet:

The heat pump will make a difference. That difference will not be massive. It will likely not exist at all in hot weather but rather in cool or cold weather because in hot weather the vehicle will be trying to dump heat from the cabin, battery, and other components all at the same time. The current AC-based system should be able to do that as efficiently as a heat pump because an AC is, in fact, a heat pump. The difference being that a "heat pump" functions identically as an AC except for a value that changes the direction that the coolant flows, thus allowing the unit to pump heat out of, or into, the relevant area/thing.

There could be other changes to the heating and cooling system that make it more efficient overall, but just changing from an AC plus resistive heaters to a heat pump doesn't really tell us anything about whether the overall system is actually more efficient in hot weather.

While it’s true that an AC system and a heat pump both move heat, the heat pump’s ability to reverse the flow of refrigerant makes it more versatile and efficient. The refreshed R1S leverages this technology not just for cold weather, but to enhance overall thermal management and efficiency, even in hot conditions.

You can also do this with traditional AC and no "heat pump". It's all about the valving involved.

True, but typically there is minimal benefit to do so in the summer so companies don't spend the cash.

Ok, with all this new knowledge would any of you pay $6k for a heat pump as an option on any Rivian configuration?

Just this thread? ?

I'd probably go $1k, but not $6k.
