Savings Formula:
From: | To: |
Definition: This calculator estimates the cost savings from using a heat pump compared to traditional heating systems.
Purpose: It helps homeowners and businesses evaluate potential savings when considering a switch to heat pump technology.
The calculator uses the formula:
Where:
Explanation: The difference in energy consumption between systems is multiplied by the electricity rate to determine dollar savings.
Details: Accurate savings estimation helps justify heat pump investments, forecast payback periods, and make informed energy decisions.
Tips: Enter your current system's annual energy use, estimated heat pump energy use, and local electricity rate (default $0.12/kWh).
Q1: How do I find my current system's energy use?
A: Check your utility bills for annual kWh usage or multiply system wattage by hours of operation.
Q2: What's a typical heat pump energy consumption?
A: Heat pumps typically use 50-75% less energy than resistance heating, but exact numbers depend on climate and system efficiency.
Q3: Should I include cooling savings too?
A: This calculator focuses on heating. For complete analysis, consider adding cooling season savings if replacing AC with a heat pump.
Q4: What if my rate varies by season?
A: Use a weighted average rate or calculate separately for summer/winter rates then sum the results.
Q5: Does this account for installation costs?
A: No, this only calculates operational savings. Compare savings to installation costs to determine payback period.
