You only need single phase into the home. You take two 120V circuits in your fuse box and combine them to get 240V. That is how residential homes get 240V for electric water heaters, stoves, clothes dryers, etc.
As to heating taking less power than A/C. I don't have to do the calculations, I have an EV. Heating takes roughly 3x more power than running the A/C even at 90-100F. Take a look at my fuel log. Those giant dips in the winter are from running the heat. My car has heated seats but those don't defrost / defog the windshield.
