California's state energy loan program, GoGreen Home, can finance a water heater. No utility that DuloCore checked on October 13, 2026 lists its own home water heater loan. Income-qualified households may not need a loan at all, because utility and state programs can replace a water heater at no cost.
What Is the State Water Heater Financing Program in California?
It is GoGreen Home Energy Financing, run by a state authority under the State Treasurer. On October 13, 2026 its lender page showed 11 credit unions lending from 3.49% to 10.00% APR for energy upgrades.
APR means annual percentage rate, the yearly cost of a loan. The state doesn't lend the money itself. The State Treasurer's GoGreen Home page says the program gives participating lenders a credit enhancement, a backstop against default, so they can offer lower rates and longer payback terms.
The GoGreen Home lender page lists each credit union's own rates. For loans that are not solar, it showed on October 13, 2026:
- Rates from 3.49% to 10.00% APR, depending on the lender and the length of the loan.
- Loan amounts from $200 to $50,000.
- Terms of up to 15 years.
The page also says qualifying heat pump upgrades can get 0% financing, offered to eligible households in underserved California communities. It shows no date for its rates, so confirm the rate with the lender.
Which Water Heaters Can Be Financed Through GoGreen Home?
Five kinds are on the program's eligible list: gas tankless, gas storage tank, electric tankless, solar, and heat pump water heaters. A contractor must install each one.
The eligible measures list does not give any of the five its "Self-install eligible" label. It requires ENERGY STAR certification for four of them and lists no requirement for the electric tankless type. The same page says your gas and electric companies determine which upgrades qualify, so check the list for your address before choosing a model.
Who Can Apply for a GoGreen Home Loan?
Owners and tenants in homes of one to four units served by PG&E, SDG&E, SCE, SoCalGas or City of Palo Alto Utilities. Tenants need the owner's written permission.
The GoGreen Home residential page lists the property types: a single-family home, townhome, condo, duplex, triplex or fourplex, or a manufactured or mobile home on a site-built foundation. It says customers who get electricity from a publicly owned utility, the kind a city or district runs, are eligible as well and may finance most measures. It also lists no property lien among the program's features.
DuloCore's eligibility check shows which verified programs fit a specific household.
Do California Utilities Offer Water Heater Financing?
No utility DuloCore checked on October 13, 2026 lists its own home water heater loan. They list rebates, and no-cost replacement for income-qualified households.
The GoGreen lender page, linked above, says PG&E, SDG&E, SCE and SoCalGas are not making an offer to lend and have no role in reviewing or approving an application.
| Utility (official pages, October 13, 2026) | Water heater loan listed | What the pages do list |
|---|---|---|
| PG&E | None for homes. Its 0% interest loans are described for businesses | Energy Savings Assistance: heat pump water heater upgrade or repair at no charge |
| SDG&E | None on its rebates page | Energy Savings Assistance: water heater repair or replacement and heat pump water heater, at no cost |
| SoCalGas | None on its rebates page | Rebates: $80-$1,500 for a high-efficiency tankless water heater, $300-$575 for a high-efficiency storage water heater |
| SMUD | None on its rebates pages | Rebate of up to $4,000 on a qualifying heat pump water heater |
| LADWP | None in its residential program list | Consumer Rebate Program: up to $2,500 per heat pump water heater |
SMUD's page adds that a contractor may offer the rebate amount up front and collect it from SMUD after the project. The rebate calculator shows the verified programs for an address, and the California water heater rebates page lists them by program.
Frequently Asked Questions
Can I get a water heater replaced for free in California?
Possibly, if the household is income-qualified. SDG&E's Energy Savings Assistance page, linked in the table, sets the income limit at 250% of the Federal Poverty Guidelines. That is $39,900 for one person and $82,500 for a household of four from June 1, 2026 to May 31, 2027. Not every customer qualifies for every product, and existing appliances must meet age requirements.
The state's Weatherization Assistance Program also lists repairing or replacing water heaters for low-income owners and renters. The page says to contact your county's local service provider with questions on eligibility. DuloCore's weatherization income guidelines article explains the limits.
Does SMUD or LADWP offer a water heater loan?
Neither lists one. DuloCore read SMUD's Rebates for my home page and all five pages of LADWP's residential program list on October 13, 2026 and found rebates only.
Can renters use GoGreen Home financing for a water heater?
Yes, with the property owner's written permission, according to the GoGreen Home residential page linked above. Lenders set their own rules, so ask the credit union before applying.
