and still coming down. But warm weather is just around the corner. The top of our heat pump was clear yesterday. Unrelated to boating, but this is the first winter with an air source heat pump in our house. It's worked out better than I expected working with our pellet stove to keep us comfortable using surprisingly few KWH in one of the coldest winters on record.

As these air source heat pumps become more efficient, not only will we see them on houses in the Northeast, better marine versions are sure to become more common. Not only for AC, but for heat as Doug has found out on his Sabre 40.
