My house was built in 2018. 1100 Sq/ft 2 bed and 2 bath with a daylight walkout basement with a glass slider.

We have one heat pump in our living area that aims almost directly down our main hall to the bedrooms and bathrooms. The bedrooms all have electric baseboard. We have no other heat. The basement is entirely unheated and the main floor is insulated from the basement. We have a heat pump hybrid water heater in the basement.

In the winter I let the heat pump run on its own until it starts to struggle to keep up at that point I start turning up the electric baseboard just until it kicks on (analog thermostats in each bedroom). I'll play with the thermostats until the average house temperature is a degree or 2 from the heat pump set temperature.

The highest electric bill I've had in 5 years is probably just under $400. Last month I used 36KW. Highest monthly usage in last 3 years was 42KW and that was January of 22.

The no heat in the basement is going to get corrected with a pellet stove I got for free from my father. It gets as low as the high 30's down there but I've had no issues so far.
