Field notes
The calculator models delivered heat rather than simply comparing fuel prices, combining energy content with stated equipment efficiencies. Its example uses an 81-million-BTU seasonal load and a heat-pump COP of about 3.0, then reports both per-unit fuel use and total seasonal cost. Users can replace the displayed national-average prices with their own electricity, gas, oil, propane, pellet, or firewood figures, which can change the ranking.
