Irvine Water Heater FAQs
Answers to the questions Irvine homeowners ask us most.
Don’t see yours? Call us at the number above or request service online.
How much does water heater installation cost in Irvine, CA?
Installation cost in Irvine depends on fuel type (gas, electric, or heat pump), tank size, venting and seismic-strapping requirements, and whether code upgrades are needed for the permit issued through the City of Irvine Community Development – Building & Safety. Tank-to-tank replacements are typically the most affordable option, while tankless and hybrid heat-pump systems cost more up front but deliver better efficiency and often qualify for SoCalGas or Southern California Edison rebates. We provide a flat, written quote up front — no hourly surprises — and can usually complete same-day installs if you call by 12 PM.
Do you offer same-day water heater repair near me in Irvine?
Yes. Call by 12 PM and we’ll have a licensed California technician at your Irvine address the same day in most cases. We carry common replacement parts (thermocouples, gas valves, heating elements, anode rods, T&P valves) on the truck, and we service gas, electric, tankless, and hybrid heat pump water heaters throughout Irvine and across Orange County.
Is Fast Water Heater Co. licensed in California?
Yes — Fast Water Heater Co. is a fully licensed California contractor through the Contractors State License Board (CSLB), bonded, and insured, serving Orange County and the greater Southern California region. Every installation is performed by background-checked, W–2 technicians (not subcontractors), pulled under permit with the local building department, and backed by our workmanship warranty.
What water heater brands do you install in Irvine?
We install and service Bradford White, Rheem, A. O. Smith, Rinnai, Navien, Noritz, and Stiebel Eltron tank, tankless, and heat pump water heaters throughout Irvine. Our most-requested Irvine installs are 40–50 gallon gas tanks for single-family homes in Woodbridge and Northwood, and Rinnai or Navien tankless units for newer townhomes near Great Park and Portola Springs. Heat-pump models like the Rheem ProTerra may qualify for SoCalGas and SoCal Edison energy-efficiency rebates — ask us for current program details.
Do I need a permit for water heater replacement in Irvine?
Yes. The City of Irvine Building & Safety Division requires a plumbing permit for every water heater replacement. Our installers pull the permit on your behalf and make sure the install meets current California Plumbing Code requirements, including the two-strap seismic bracing required statewide, proper T&P drain routing, combustion air, expansion-tank sizing, and drip-pan drainage. The permit stays with the property and protects your resale value.
How long does a water heater installation take in Irvine?
Most standard tank-to-tank water heater replacements in Irvine take 2–4 hours from arrival to cleanup. Tankless and heat pump installations typically take 4–8 hours depending on venting, gas-line sizing, electrical panel capacity, and whether the location is changing (for example, converting an interior closet install to a garage tankless). For same-day service, call by 12 PM and we’ll confirm a technician window.
Do you service tankless water heaters in Irvine?
Yes. We install, flush, descale, and repair tankless water heaters across Irvine and all of Orange County. Annual descaling is especially important for Irvine homes on Irvine Ranch Water District supply — the harder mineral content common to Southern California can shorten heat-exchanger life if a tankless unit isn’t flushed yearly. We service Rinnai, Navien, Noritz, and most other major tankless brands.
What areas of Irvine do you serve?
We serve all Irvine neighborhoods — Woodbridge, Turtle Rock, University Park, Northwood, Quail Hill, Oak Creek, Westpark, El Camino Real, Orchard Hills, Great Park, Portola Springs, and Stonegate — plus the broader Orange County region including Tustin, Lake Forest, Newport Beach, Costa Mesa, Aliso Viejo, Laguna Hills, Mission Viejo, Santa Ana, Anaheim, Garden Grove, Huntington Beach, Yorba Linda, Fullerton, Brea, Orange, Fountain Valley, and Cypress.
