Estimate how many years it may take for a heat pump investment to pay back based on installation cost, incentives, current annual heating cost, expected energy savings, and annual maintenance savings.

Estimate the total installed cost to replace a heat pump based on system size, equipment efficiency, installation complexity, ductwork modifications, and regional labor pricing.

Compare estimated annual heating costs for a heat pump versus a gas furnace based on home heating demand, local electricity and natural gas prices, heat pump efficiency, and furnace AFUE. The result shows the annual cost difference, where a positive value means the heat pump costs more to run and a negative value means the heat pump costs less.

Compare estimated annual heating cost savings when switching from an oil furnace to a heat pump based on annual heating demand, oil price, electricity price, furnace efficiency, and heat pump efficiency.

Estimate the recommended mini split capacity in BTU per hour based on room size, ceiling height, insulation quality, climate severity, and sun exposure.

Estimate the recommended mini split system size in tons based on room area, ceiling height, insulation quality, climate severity, and sun exposure.

Estimate the recommended air source heat pump capacity based on floor area, insulation quality, climate severity, ceiling height, and occupancy.

Estimate the required ground source heat pump capacity in kW from building heat demand, climate severity, insulation quality, and system efficiency assumptions.

Estimate the electricity cost to run a heat pump based on heating demand, system efficiency, operating hours, electricity rate, and seasonal usage.

Estimate the monthly operating cost of a heat pump based on heating demand, seasonal efficiency, electricity rate, runtime, and climate adjustment.

Estimate monthly electricity consumption for a heat pump based on heating demand, runtime, system capacity, efficiency, and climate conditions.

Estimate annual electricity use in kWh for a heat pump based on home heating demand, heat pump efficiency, climate, and supplemental heating share.

Estimate heat pump efficiency as COP (Coefficient of Performance) based on heating output, electrical input, outdoor temperature, and system type adjustment.

Estimate the coefficient of performance (COP) of a heat pump using heating output, electrical power input, outdoor air temperature, and supply water temperature. COP is adjusted from the measured output-to-input ratio using temperature lift effects for a more realistic operating estimate.

Estimate seasonal heating output, seasonal electricity use, or effective HSPF for a heat pump using heating capacity, annual heating hours, part-load factor, and electricity use. HSPF is the total seasonal heating output in BTU divided by total seasonal electricity use in watt-hours.

Estimate annual savings from switching to a heat pump based on current annual heating costs, expected heat pump efficiency, electricity price, climate, and available incentives.

Estimate the natural gas used by a furnace based on input capacity, daily runtime, heating days, furnace efficiency, and gas energy content. Useful for approximating seasonal gas consumption.

Estimate the electricity used by a furnace blower and controls based on blower wattage, daily runtime, heating season length, and electricity rate. This calculator returns the estimated operating cost for the heating season.

Estimate the installed cost to replace a residential furnace based on home size, furnace efficiency, fuel type, installation complexity, and regional labor/pricing differences.

Estimate annual heating cost savings from replacing an older furnace with a higher-efficiency model based on home heating demand, current and new AFUE ratings, fuel price, and climate.

Compare the estimated annual heating cost and yearly savings of an 80% AFUE furnace versus a 96% AFUE furnace based on home heating demand, fuel price, climate, and system runtime factor.
