Yeah, whether you can do it or not is going to come down to just how many amps do you need on the heat pump. Larger houses with worse insulation in colder climates will need the 200A circuit.
I’m already electrically budgeted for central A/C, so I figure replacing the existing unit with a heat pump would be more or less “break-even”. The heat pump may even end up being slightly more efficient than the 8 y/o AC unit I have now :)
So I guess the only new load would be the heat pump water heater.
I do plan to get an EV and install a charger in the next 5 years or so, so I’ll likely end up having to upgrade my panel for 200A anyway.
What I’d look at then is demand management - basically software to delay charging the car while you run the oven or run the hot water heater on its fast-heat cycle. That can keep you inside 100A
