- Homeowners estimating winter firewood and stove needs
- Worth noticing
- The estimate uses 1991–2020 NOAA statewide heating-degree-day averages and adjusts household energy use by construction decade.
Field notes
The calculation starts with statewide heating-degree days and estimates household heat demand using federal gas-consumption figures grouped by construction decade. It then converts that demand into cords using selected wood energy values and stove efficiency, while the stove comparison uses published maker ratings. The page cautions that the averages do not account for details such as a drafty house, a closed-off floor plan, or a warmer thermostat.
