I’d look at alternatives regardless of if you decide to go the heat pump route or not

Personal experience: bought my house ~2 years ago and used a little under three tanks of oil for a heating season. Installed a pellet stove this past spring, which I mainly use for heating the home, and haven’t hit half a tank used yet

The pellet stove is paying for itself way earlier than I anticipated. I’m sure people who converted to heat pumps/stoves can say similar things
