Question 1

How much does a heat pump water heater save per year?

Accepted Answer

A heat pump water heater (HPWH) saves $300–$550 per year compared to a standard electric resistance water heater, and $100–$200 per year vs a gas tank water heater at national average energy prices. HPWHs operate at 300–400% efficiency (Energy Factor 3.0–4.0), using one-third the electricity of standard electric tanks.

Question 2

What is the payback period for a heat pump water heater?

Accepted Answer

The payback period for a heat pump water heater is typically 2–4 years when replacing an electric tank, and 4–8 years when replacing a gas tank. HEEHRA rebates of up to $1,750 and the federal home improvement tax credit (30% back) can shorten the payback period to under 2 years for qualifying households.

Question 3

What rebates are available for heat pump water heaters?

Accepted Answer

HEEHRA (High-Efficiency Electric Home Rebate Act) provides up to $1,750 for heat pump water heaters for income-qualifying households. The federal home improvement tax credit provides 30% back (up to $600 per year) for all income levels. Many utilities offer additional rebates of $100–$400.
