238 mile range?

Yes, to a point. Below a certain temperature (about 14F, I believe), a heat pump is no longer effective...

...and effectiveness suffers, even above the critical temperature, as the temperature drops towards it.

Right but over a wide range of temps (call it 15 to 70 F prox) the heat pump comes out ahead. Please, they should have offered it. I'd have paid extra

Look- you "probably" have an electric, not ICE belt driven air conditioner in your home or office.
I think you'll agree, your electric bill goes up- A LOT when you use it.

There is a fixed kw value for changing temperature in either direction. The difference is:

Summer:
Usually you'll want to change the temperature from 90'F to 70'F. A change of 20 degrees.

Winter:
Usually you'll want to change the temperature from 30'F to 70'F. A change of 40 degrees.

Hence (and no wonder) the heater drains your battery twice as much.

Ugh. Sound of head hitting table.
