I don't know if you are all electric or not. My electric will be higher, but my gas will likely be quite a bit higher, too, and water will be up a little bit (negligible) from running the taps to keep pipes clear.
I'd anticipate a 50-70% increase for the month for total utilities. (For my house, personally).
I have has on the two units in the house. The upstair never comes on in the winter. I set the fan to cycle and keep the thermostat at 60 as a fail safe. Hot water heater is gas.
The garage is a 2 ton mini-spit with heat pump. It was struggling during the coldest part.
