## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/ca/heating-comparison/?usefulHeat=18000&heatPumpCop=3&fuelEfficiency=90&electricityRate=0.2&fuelRate=0.08&electricFixed=0&fuelFixed=120

## Inputs
- usefulHeat: Annual useful heat required, kWh; type=number; required; default=18000; min=0; max=1000000000000
- heatPumpCop: Seasonal heat-pump coefficient of performance; type=number; required; default=3; min=0.5; max=8
- fuelEfficiency: Seasonal comparison-heater efficiency; type=percent; required; default=90; min=0; max=100
- electricityRate: Electricity price per input kWh; type=money; required; default=0.2; min=0; max=1000000000000
- fuelRate: Comparison fuel price per input kWh; type=money; required; default=0.08; min=0; max=1000000000000
- electricFixed: Annual additional electric fixed charges; type=money; required; default=0; min=0; max=1000000000000
- fuelFixed: Annual fuel fixed charges; type=money; required; default=120; min=0; max=1000000000000

## Outputs
- heatPumpEnergy: Heat-pump input electricity, kWh; format=number
- fuelEnergy: Comparison fuel input, kWh; format=number
- heatPumpCost: Heat-pump annual cost; format=currency
- fuelCost: Comparison heater annual cost; format=currency
- annualSaving: Heat-pump annual saving; format=currency; primary
- breakevenCop: Energy-only break-even COP; format=number

## Formula
input energy = useful heat ÷ seasonal efficiency; cost = input energy × unit price + fixed charges.

Inputs are converted to canonical units before evaluating this stated formula.

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.

Notice: Illustrative defaults are not local quotes or verified legal rules. Dated reference components and user-entered assumptions are explicitly distinguished. Professional review is pending.
