Southern California gets over 280 days of sun a year — and every one of them can heat your water for free. A solar water heating system captures that heat on your roof and delivers it to your tap, cutting the biggest chunk out of your water heating bill. In 2026, SoCalGas is paying up to $5,000 on qualifying installs. We're licensed for both the plumbing and the solar, so one accountable company handles the whole system — including the rebate paperwork.
💰 SoCalGas is paying up to $5,000 on qualifying solar water heating installs in 2026 — and the biggest rebate tier requires a tankless backup, our specialty since 2006. First-come, first-served. Ask if your home qualifies →
Solar collectors on your roof absorb the sun's heat and transfer it to your water — no electricity generated, no complicated inverters, just direct heat doing what it does naturally. The heated water is stored in an insulated tank, ready when you are.
On cloudy days or heavy-use mornings, a backup heater — tank or tankless — picks up the slack automatically. You never notice the handoff; you just notice the lower bill.
"Most plumbers can't touch the solar side. Most solar companies can't touch the plumbing side. A solar water heating system is both — which is exactly why we carry both licenses. One company, one warranty, one number to call."— The Doctor Piper difference
Some technologies fight the local climate. This one is made for it.
With 280+ sunny days a year, SoCal collectors work near their peak most of the year — the same reason solar PV took off here first. More sun in means more free hot water out.
Freeze protection is a major engineering headache in cold states. Our mild winters keep systems simpler, cheaper to maintain, and longer-lived.
Gas and electric rates in California keep climbing. Every rate hike makes the sun's free heat worth more — your savings grow over the life of the system.
Roof orientation, family size, backup preference — we design around your home, not a one-size template.
We evaluate your roof's orientation, shading, and structure, plus your household's hot water usage, to size the collectors and storage correctly.
Solar carries the base load; a tank or tankless backup covers cloudy stretches and peak mornings. As tankless specialists since 2006, we build backups that work seamlessly.
Roof penetrations, plumbing runs, permits — all handled by our own licensed crews. No subcontractor roulette on your roof.
It shines brightest for households that use a lot of hot water — bigger families, pools and spas, high gas or electric rates. The more hot water you use, the faster free solar heat pays for itself.
If your usage is light or your roof isn't a good candidate, we'll say so — and point you to the system that actually fits, whether that's tankless or a heat pump. We install all four water heating systems, so the only thing we push is the right answer.
"We had our whole house repiped and a tankless water heater installed. As a licensed architect working for a large design/build general contractor, I was very impressed with this company — they showed up and followed through when other plumbers never did."— Stephanie W. · Yelp Review · Los Angeles, CA
