Florida Heat Pump Tool
Heat Pump Savings Calculator
Compare two heating scenarios, including electric resistance at COP 1. The starting output, hours and COP values are editable examples. Nominal cooling tonnage does not verify heating capacity; use equipment-specific heating data when available.

Quick answer
How much can a heat pump save in Florida?
At the same modeled heating load, a higher COP needs less electricity and a lower COP needs more. Compare heating kWh using assumed heat output and equivalent full-load hours, then optionally add your usage rate for a cost change. This tool does not estimate cooling savings.
How This Calculator Works
Assumed heating output (Btu/h) = tons equivalent x 12,000. Heating kWh = assumed heating output x equivalent full-load heating hours / 3,412 Btu per kWh / COP. Both systems supply the same modeled heat load at constant COP; electric resistance uses COP 1. Energy difference = current kWh - proposed kWh; cost difference additionally multiplies by the entered usage rate. A negative difference means an increase.
Florida Factors to Review
Equivalent full-load hours describe heat demand as time at the assumed output, not simply thermostat runtime. COP is measured at stated operating conditions; holding it constant does not represent every winter condition. This estimate does not separately model defrost, backup heat or temperature-dependent changes in COP and heating capacity.
Choosing Your Electricity Usage Rate
The rate starts blank. Enter the per-kWh energy, fuel and other usage charges from your rate plan, excluding fixed monthly fees and taxes. A fixed fee does not disappear when HVAC use falls, so whole-bill cost divided by kWh is not necessarily the cost avoided by saving electricity. No utility tariff or current price is assumed here.
Your entered rate applies to the full modeled period. Tiered, time-of-use, minimum-bill and changing prices require more detail than one rate can provide. Dollar results estimate HVAC energy cost, not your total bill or guaranteed savings.

These sources explain rating definitions, usage charges and equivalent full-load-hour methods. They do not validate the starting scenarios for a Palm Beach County home. The cooling evaluation protocol is a historical methodology reference, not a current local calibration.
Calculator FAQs
Does a lower heating cost guarantee replacement savings?
No. This comparison uses one assumed heating load, constant COP values and an optional entered rate. It excludes installation cost, cooling use, maintenance differences and future price changes. Review a system-specific estimate before deciding.
What is COP?
COP is heat delivered divided by electrical energy used at stated conditions. COP 3 means three units of heat per unit of electricity under those conditions; it is not a guaranteed seasonal average. Use a comparable operating basis for both heating scenarios.
Should I compare heat pump and central AC replacement?
Yes. Compare comfort, installed scope, cooling efficiency, heating needs, thermostat setup, ducts, and maintenance before choosing equipment.
