The house we moved into in Fall of 2020 is excellent in most every way. Except it has an oil boiler. Heating a large house. In New Hampshire.
After seeing the first January oil bill, I knew it was time for heat pumps. I had one at my previous house, which had relatively cheap natural gas heating. This was a whole other level of financial pain. Burning oil for heat does not have much of a future.
So, I planned all year for a multi-step installation. This is the story of the first step: heating the bedrooms and my wife's office with an air source heat pump.
