Enter annual usage and current utility rates. This is arithmetic, not a building-energy model; weather, equipment efficiency, ducts, and rate schedules materially affect actual cost.
Heat pump electricity
$1,330/year
Gas fuel only
$1,200/year
Gas total excludes fixed charges, furnace electricity, and maintenance. Heat-pump usage must come from an energy model, monitored data, or a documented estimate. Do not compare equipment using rates alone.
Results are planning aids based on the information entered and the current Summit catalog. A qualified contractor, program administrator, manufacturer documentation, AHRI certification record, and local authority may be required for the final decision.
