The best public price data for San Diego covers heat pump water heaters. In San Diego County, the median installed project in a state incentive program cost about $9,900 before incentives. No official source publishes San Diego prices for gas tank or tankless water heaters, so this page gives none.
These figures come from real, fully paid projects, not quotes. Here's what they cover and what they don't.
How Much Does a Heat Pump Water Heater Cost to Install in San Diego?
The median San Diego County project cost $9,873, and the middle half ran $7,423 to $11,022, before incentives. That is a DuloCore calculation from TECH Clean California program data (CPUC), July 7, 2024–July 6, 2026, n=177; the program's single-family incentives have been fully reserved since November 14, 2025.
| Area (heat pump water heater, one unit, single-family, market rate) | Projects (n) | Median project cost | Middle half (25th–75th percentile) |
|---|---|---|---|
| San Diego County | 177 | $9,873 | $7,423–$11,022 |
| All of California | 4,713 | $7,837 | $6,249–$8,798 |
Both rows are DuloCore calculations from the same program data and date range. Nearly all of the San Diego projects replaced a natural gas water heater.
Each figure is the contractor's total project cost, covering equipment and installation, before any incentive. Projects done through an incentive program may differ from the wider market, and some include extra work such as electrical upgrades.
Why Does San Diego Cost More Than the State Median?
The data doesn't say why, so this page doesn't guess. San Diego County's median was about $2,000 above the statewide median of $7,837 in the same program data. Get several written quotes that list equipment, labor, permit and any electrical work separately.
For comparison, SMUD publishes its own installed-cost table for Sacramento: a median of $6,220 for gas-to-electric heat pump water heaters, from SMUD program projects over the past 12 months, before rebates.
What About Gas Tank or Tankless Water Heaters?
We found no official San Diego price data for gas tank or tankless water heaters, so this page gives no figures for them. The program data above covers heat pump water heaters only.
If you're replacing a gas tank like-for-like, written quotes from licensed plumbers are the most reliable guide. Ask whether the price includes the permit and haul-away.
Are There Rebates to Lower the Cost in San Diego?
For most households, not anymore. SDG&E's rebates page says the Golden State Rebates retail offerings have ended, including a $500 heat pump water heater coupon. And the federal 25C credit ended for property placed in service after December 31, 2025.
Income-qualified homeowners and renters can still get a heat pump water heater at no cost through SDG&E's Energy Savings Assistance (ESA) program. Our San Diego water heater rebates guide covers who qualifies and how to apply.

Is there a tax credit for a water heater installed in 2026?
