California is moving toward electric water heating, and heat pump water heaters are the technology doing it. They use roughly a third of the electricity of a conventional electric water heater by moving heat out of the surrounding air rather than generating it.
Peak West Plumbing installs them across South Orange County. We hold both a C-36 plumbing license and a C-10 electrical license, which matters more on this job than on almost any other. Call (949) 636-4118.
A heat pump water heater is not a like-for-like swap for a gas unit. It needs:
Most contractors hold one license and subcontract the other. That means two companies, two schedules, two invoices, and finger-pointing if something doesn't line up. We do both. One permit path, one crew, one point of accountability.
The most common unbudgeted cost on a heat pump water heater installation is an electrical panel upgrade. Many older Orange County homes are on 100-amp service with no spare capacity, and a heat pump water heater needs a dedicated 240V circuit.
Whether your panel can handle it depends on a load calculation, not a guess. If a contractor quotes you a heat pump water heater without looking at your panel, that quote is incomplete. A panel upgrade typically adds several thousand dollars, and finding out mid-installation is the worst way to learn it.
We run the load calculation before quoting. If your panel needs work, you'll know the full number before anything is ordered — and we're licensed to do that part too.
We'll tell you if your home is a poor fit. Sometimes the right answer is a high-efficiency tank or a tankless unit, and we'd rather say so than sell you the wrong equipment.
This is the section where most contractor websites are wrong. Here's the current state:
The Section 25C Energy Efficient Home Improvement Credit, which offered up to $2,000 for qualifying heat pump equipment, was terminated by the One Big Beautiful Bill Act signed July 4, 2025. It applies only to equipment placed in service on or before December 31, 2025. Section 25D expired on the same date. If your system is installed in 2026, there is no federal credit — regardless of when you ordered the equipment. If you installed before the deadline, you can still claim it on your 2025 return.
The statewide program stopped accepting new single-family heat pump water heater and heat pump HVAC reservations on November 14, 2025 after funding was nearly exhausted.
Rebates for single-family homes in Southern California were fully reserved as of January 7, 2026, and statewide as of February 24, 2026. New reservations go to a waitlist and are only eligible if the heat pump is installed after the reservation is approved.

I need a 6th star! I ordered a new fridge but it couldn’t be installed because the ancient water valve was frozen. Peak West owner Mustafa came the same day and fixed it, then hooked up the new fridge. After he finished I asked about a knocking sound coming from the water heater. He suspected it was excess water pressure. Boy was he right! Twice the maximum pressure! Another plumber had previously fixed a couple of leaks and recommended we replace all our “cheap” copper piping. Mustafa said the pipes were fine, it was the excess pressure that was the problem. He installed a water pressure regular and saved me thousands of dollars (and incredible headaches) since I didn’t need to replace all of our pipes. So honest! Easy to communicate with, too. Very nice, explains what he does and why. I can’t recommend him enough!
I was looking for water filtration for my house and was checking out few companies in the area (Irvine). Peak West Plumbing was one of the companies i requested an estimates. Their price was very reasonable and yet when they called me for details and discussion of the process i could say that the person on the phone knew every small detail about the job that was to be done. I am a very detail-oriented person, and the way it was explained to me was perfect. At the end of the call i had all answers to my questions that i was planning to ask but never asked because he already answered all of them the way he explained it to me. We agreed on terms and the job was done in 4-5 hours by 2 technicians. I also liked that owner came to check if everything is okay while they were installing everything. Very impressed with this company and definitely will recommend it to all my friends. Very polite and good customer service, reliable and very responsive. Thank You for your 5 Star Service! Well done!
Get answers to common questions about heat pump water heater installation, electrical requirements, and our services.
A heat pump water heater uses heat from the surrounding air instead of generating heat directly, making it a more energy-efficient option compared to conventional electric water heaters.
Most heat pump water heater installations require a dedicated 240V electrical circuit. Some homes may also need a panel upgrade depending on available electrical capacity. Peak West Plumbing performs a load calculation before installation.
Yes. Peak West Plumbing handles both plumbing and electrical requirements with C-36 plumbing and C-10 electrical licenses, providing one contractor for complete installation.
No. Heat pump water heaters work best in spaces with enough air volume, proper electrical capacity, and suitable installation conditions. Some homes may require another solution.
Installation time depends on your home's plumbing setup, electrical requirements, permits, and whether panel upgrades are needed. Peak West Plumbing evaluates your system before quoting.
