Commercial water heater repair, replacement, and code-compliant installation for restaurants, retail, and multi-tenant buildings across Marin & Sonoma County.
When a commercial water heater goes down in a Petaluma kitchen or a San Rafael salon, you can't close the doors and wait — you need hot water and a county inspector's sign-off, fast. John Owens Services has kept North Bay businesses running since 1986, sizing and installing systems that meet Sonoma County's food-facility plumbing rules (a recirculation pump once any fixture sits more than 60 feet from the heater, and at least 2 GPM at a 60-degree rise to every sink) and California's Title 24 energy code. From Novato strip-mall tenants to Santa Rosa's downtown dining corridor, we handle the high local water hardness that quietly scales heat exchangers and shortens a unit's life.
We offer same-day commercial service across Marin and Sonoma whenever possible, because a down unit can force a restaurant or salon to close. As a licensed contractor (CA #501853), we diagnose, repair, or replace and pull the permit so you reopen compliant.
Yes — food facilities require at least 2 GPM at a 60-degree rise to each sink, and a recirculation pump once any fixture is more than 60 feet from the heater. We size and install every commercial water heater to pass county inspection and California Title 24 the first time.
Marin and Sonoma's hard water deposits heavy calcium scale on heat exchangers and tank bottoms — pounds of it over a unit's life — which cuts efficiency and shortens lifespan. We recommend descaling, water treatment, or scale-resistant units to protect your investment.
Absolutely. We help North Bay businesses move to tankless or high-efficiency commercial water heaters that meet Title 24's high-efficiency-ready requirements, then handle annual descaling so hard-water scale doesn't choke the heat exchanger.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
