What heat pump and do you know how much of that bill was the heat pump ?

I'd say 80% of it.

My hot water, washer and dryer, fridge, and oven are also electric so that uses quite a bit. But it's immediately noticeable how much more power you use once it gets cold.

Anything above 40 degrees doesn't seem to use an insane amount of power, but once you get those below freezing days it can easily crank 80-100KwH in a single day.

I bet your auxiliary heating system is resistive electric. If so, you might realize significant savings if you investigate how to adjust its duty cycle and how to modify the switch temperature.

this is likely right on. heat pumps are most effective at moderate temps. once it's cold enough they tend to switch to aux resistive heating.

What water heater you have and what heat pump. On the coldest day this month my heat pump used 32 kwhr. You might have heat strips as auxiliary heating. Newer heat pumps like the one I have don’t need backup heat. I also have heat pump water heater which uses 3-5 kwhr per day in winter
