Payback math

  • Net install cost (after rebates): $6,000
  • Payback period: N/A
  • 10-year savings (post-payback): $0
  • CO₂ avoided: 32 kg/year (vs current fuel)
Federal Inflation Reduction Act offers up to $2,000 federal tax credit + state-level rebates often $4,000-8,000. Check energy.gov for your state. Cold-climate heat pumps (Mitsubishi Hyper-Heat, Bosch IDS) work reliably to -5°F. Below that, dual-fuel hybrid setups bridge the gap.

What it does

Calculate annual savings + payback for replacing gas/oil/propane/electric-resistance heating with a heat pump. Includes IRA federal tax credit + state rebate inputs, electricity rate, climate zone (mild/moderate/cold/ very cold), and CO₂ reduction. COP scales: 3.5 in mild, down to 2.5 in very-cold climates with cold-climate pumps.
