Understanding Heat Pump ROI
Switching to a heat pump is one of the most effective ways to reduce home energy costs and lower your carbon footprint. Unlike traditional furnaces that generate heat by burning fuel, heat pumps transfer heat from the outside air into your home, achieving efficiencies of 200% to 400%.
How the Calculation Works
This calculator estimates your return on investment based on four key factors:
- Net Cost: Total installation price minus any federal tax credits (like the 25C credit in the US) and local utility rebates.
- Current Fuel Displacement: Savings are highest when replacing expensive fuels like propane, oil, or electric baseboard heating.
- Efficiency Gains: High-efficiency units (with high SEER2 and HSPF2 ratings) offer greater year-over-year savings.
- Payback Period: The time it takes for your cumulative energy savings to equal your initial net investment.
Real-World Example
If you currently spend $3,000 a year on oil heating and switch to a high-efficiency heat pump, you might save 40% ($1,200) annually. If the net cost after a $2,000 rebate is $10,000, your payback period would be approximately 8.3 years. Over a 15-year lifespan, that results in $18,000 in savings, more than doubling your initial investment.
