Sounds really sensible if you are in California right now and the weather is fairly pleasant.

If you had three Sanyos, or maybe four Sanyos you might be able to ride out this foul streak with ease.

But the kind of weather you are now facing is the situation that Ground source Heat Pumps were made to handle well.
Twenty-five feet down in the ground, the temperature is around 47 degrees F, not -4 degrees F.
You may decide that the technology does not fit your budget, or that you'll never live long enough to pay it off... but physics will not be denied.
