What's included
What Our Tankless Installation Includes
Every Tankless Water Heater Installation in Newport Beach includes the parts and labor below. We list what is standard so you can compare quotes apples to apples. Add-ons like gas line upsizing or new vent runs are quoted separately before we start.
Unit & Mounting
We supply and mount your Rinnai, Navien, Noritz, or Rheem unit on a bracket rated for the weight. Includes seismic strapping to California code and clearance checks for the vent and service access.
Gas Line Connection
We connect the unit with a properly sized gas flex connector and test every joint with a gas leak detector. If your existing line is undersized, we quote the 3/4-inch upgrade before install day.
Venting & Condensate
Includes stainless steel vent pipe to code and a PVC condensate drain line with a neutralizer kit. We route the vent to avoid backdraft and keep the termination clear of windows and doors.
Water Connections
We install dielectric unions, an isolation valve kit, a pressure relief valve, and a thermal expansion tank. These parts protect the heat exchanger and make future descaling a 45-minute job.
Permit & Haul-Away
We pull the gas fitting permit, meet the inspector, and haul your old tank away at no extra charge. You get the signed-off permit card and warranty registration for your records.
Service overview

We run a dedicated gas line, mount the heater, install a stainless steel vent pipe and PVC condensate drain line, then pressure-test every connection.

How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
Our Tankless Installation Process
The process flexes to the condition, but these checkpoints keep decisions clear.
Phone Assessment
We ask about your current heater, fuel type, household size, and where the unit will mount. You get a ballpark range on the call, usually $3,200 to $6,500 installed. We schedule a same-day Tankless Water Heater Installation Newport Beach visit if you are without hot water.
On-Site Sizing
A licensed tech measures incoming gas pressure with a pressure gauge, checks the meter capacity, and calculates flow demand. A three-bath home needs 8 to 11 gallons per minute. We confirm vent routing, condensate disposal, and whether your gas line needs upsizing from 1/2-inch to 3/4-inch.
Permits & Prep
We pull the local gas fitting permit and schedule the inspection. On install day we lay drop cloths, shut off the gas, drain the old tank, and cut the vent penetration. Most jobs need one day on site. We haul the old tank away at no extra charge.
Install & Test
We mount the unit, run the gas flex connector, solder or press the water lines, and install the stainless steel vent pipe and PVC condensate drain line. A gas leak detector and multimeter verify every connection. We set outlet temperature to 120°F and run hot water at three fixtures at once.
Walkthrough & Registration
We show you the isolation valves, filter cartridge, and error code display. You get the warranty paperwork and we register the unit with the manufacturer. Annual descaling with a descaling pump kit keeps the heat exchanger clean. Call us if you see any error code lockout.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Gas leak detector
We test every gas joint after connection. A combustible gas detector finds leaks a soap bubble test misses, especially on flex connectors.
Pressure gauge
We measure incoming gas pressure and water pressure before and after install. If your line drops below 7 inches water column, we upsize it.
Multimeter
Used to test flame sensor resistance, ignition components, and electrical connections on both gas and electric tankless units.
Tubing cutter and pipe wrench
Clean cuts on copper and PEX, plus proper torque on gas and water fittings. No hacksaw burrs that damage seals.
Vent pipe crimper
We crimp stainless steel vent pipe to a precise fit so joints seal tight and pass combustion analysis on the first test.
Descaling pump kit
We leave your system flush-ready and use the pump kit for annual maintenance to dissolve scale from the heat exchanger.
Flow meter
We measure actual gallons per minute at your fixtures to size the unit correctly instead of guessing from bathroom count.
Use cases
When to Schedule Tankless Installation
These examples show how the service framework adapts rather than forcing every call through one repair.
Balboa Island Cottage Space Fix
A 1920s cottage had a tank wedged into a closet so tight the door would not close. The homeowner was considering an outdoor install that would have failed code. → We mounted a Rinnai unit high on the wall, ran stainless steel vent pipe through the side wall, and reclaimed the entire closet floor. The inspector signed off first visit. The homeowner gained 6 square feet of storage.
Newport Coast Multi-Bath Upgrade
A 4,500-square-foot home with four bathrooms had two 50-gallon tanks that still could not keep up. Guests in the master suite got cold water when the kitchen ran. → We installed a single high-capacity Noritz unit rated at 11 GPM, ran a new 3/4-inch gas line, and added a condensate neutralizer kit. The home now serves four showers plus the kitchen simultaneously at 120°F.
Problems we solve
Problems We Solve with Tankless Installation
Most homeowners call us because of one of these four issues. A proper Tankless Water Heater Installation in Newport Beach fixes the root cause instead of patching it.
Running out of hot water with a full house
We size a tankless unit to your fixture count, usually 8 to 11 gallons per minute. You get continuous hot water at 120°F for as long as the tap runs, even with three showers going at once.
Tank leaking or rusting in the garage
We drain and remove the old tank, then mount a wall unit out of the flood zone. Same-day Tankless Water Heater Installation Newport Beach is available when you call before noon.
Hard water scaling up the heat exchanger
We install a water filter cartridge and isolation valve kit on every job. Annual descaling with a descaling pump kit keeps the heat exchanger clean and restores factory flow.
No space for a tank in a coastal cottage
A wall-mounted tankless unit needs about 3 square feet. We mount it high, run the vent through the side wall, and reclaim your floor space for storage or laundry.
Pricing process
Tankless Installation Pricing in Newport Beach
$3,200 - $7,500 depending on scope
Gas line sizing
If your existing line is 1/2-inch, we may need to run 3/4-inch to feed a 199,000 BTU unit. That adds $600 to $1,400 depending on run length and access.
Vent run complexity
A short side-wall vent is cheap. A long vertical run through a coastal closet or a roof penetration adds $400 to $900 in materials and labor.
Unit capacity
A 7 GPM unit for a condo costs less than an 11 GPM unit for a four-bath home. Expect $400 to $1,200 difference between the smallest and largest residential models.
Customer reviews
What Newport Beach Homeowners Say
★★★★★
“Our 12-year-old tank finally rusted out on a Friday. They came Saturday morning, pulled the permit, and had a Navien running by 3 p.m. The tech showed me the gas pressure reading before and after the line upgrade. No more running out of hot water when the in-laws visit.”
★★★★★
“The closet in our cottage was too tight for a tank. They mounted a Rinnai on the wall, ran the stainless vent through the side wall, and reclaimed the whole floor. The inspector signed off first try. They even set up the isolation valves so I can flush it myself.”
★★★★★
“We manage six units and needed three tankless installs done fast. They handled permits, gas line upsizing, and condensate drains on all three in two days. Tenants had hot water the same night. Their pricing was clear and the final invoice matched the quote.”
How much does Tankless Water Heater Installation cost in Newport Beach CA?
Most installs run $3,200 to $6,500 in 2026, including the unit, gas line work, venting, permit, and haul-away. A simple swap in a garage with an existing 3/4-inch gas line lands near the low end. If we need to upsize the gas line or run a longer stainless steel vent, expect $5,000 to $7,500. We quote the range before we start.
Who installs Tankless Water Heaters in Newport Beach California?
Only a licensed plumbing contractor should touch a tankless install. We hold a California C-36 license through the CSLB and pull a gas fitting permit for every job. That matters for your warranty and your insurance. Unpermitted installs can fail a home inspection and void the manufacturer warranty on your Rinnai or Navien unit.
How long does on-demand water heater installation take in Newport Beach?
A standard tank-to-tankless swap takes four to six hours on site. Add two to three hours if we need to upsize the gas line or run a new vent through a coastal closet. Most homeowners have hot water the same evening. We schedule the permit inspection within a few days, and you do not need to be home for it.
Do I need a permit for Tankless Water Heater Installation in Newport Beach CA?
Yes. Newport Beach requires a gas fitting permit for any tankless water heater replacement, and the work must meet Uniform Plumbing Code and California Building Code standards. We pull the permit, meet the inspector, and hand you the signed-off card. Skipping the permit can cost you at resale and may void your homeowner insurance coverage.
