Vermont’s winters
A normal heating season here has 8,060 heating degree days (1991–2020 average; U.S. lower 48: about 4,300).
Last season (2025–26) had 8,073, close to normal.

In the coldest season of the last 30 (2002–03) the same house would have needed 9% more heat; in the mildest (2011–12), 15% less.
What this comparison leaves out
- Equipment you already have. Switching fuels means new equipment. This page compares the cost of heat, not the cost of a new furnace, boiler or heat pump.
- Availability. Natural gas needs a utility main on your street.
- Heat pumps in deep cold. A heat pump’s efficiency falls as it gets colder. The seasonal COP of 2.5 used here suits a modern unit in a moderate climate; older units, or cold-climate homes with resistance backup, do worse.
- Your rate structure. Gas and electricity prices here are state averages including fixed charges. Each extra unit on your bill may cost a little less.
