Net cost = install − rebate. Annual savings = old heat bill − heat-pump energy − added maintenance. Payback = net cost ÷ savings.
Compare today’s heating bill to a heat-pump energy bill after install cost and rebates, then read simple payback years.
How this calculator works
Compare today’s heating bill to a heat-pump energy bill after install cost and rebates, then read simple payback years. Net cost = install − rebate. Annual savings = old heat bill − heat-pump energy − added maintenance. Payback = net cost ÷ savings. Scenario: $14,000 install, $2,000 rebate, gas heat $2,400/year, heat-pump electricity $1,100/year → $12,000 ÷ $1,300 ≈ 9.2 years.
Net cost = install − rebate. Annual savings = old heat bill − heat-pump energy − added maintenance. Payback = net cost ÷ savings.
Scenario: $14,000 install, $2,000 rebate, gas heat $2,400/year, heat-pump electricity $1,100/year → $12,000 ÷ $1,300 ≈ 9.2 years.
