Why Choose FKM Plumbing for Tankless Water Heater Replacement in Los Angeles, CA?
Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California install softeners or scale filters. Hard water is tough on tankless heat exchangers, and many early failures trace back to scale and skipped flushing. We size, install and set up each replacement so it holds up to your local water supply.
- Right-Sized Units, We calculate gallons per minute and temperature rise for your fixtures instead of estimating from square footage.
- Endless Hot Water, Never run out of hot water, even during peak demand, a true luxury for busy Los Angeles households with multiple showers or large families.
- Energy Savings, Tankless water heaters only heat water when you need it, which can significantly reduce energy use compared to traditional tank models, a big plus for Southern California utility bills.

Exterior Mount Tankless Units in Los Angeles, CA
Many homes have tankless heaters mounted on an exterior wall with no venting at all, since the unit exhausts directly outside. These units face sun, rain and temperature swings, which can break down plastic covers and wiring over time. On an occasional cold night, covering backflow preventers and outdoor valves is usually all it takes to avoid a break. When we replace them, we check the pipe cover, freeze protection settings and the electrical connection. We can add a protective pipe cover kit to guard the water and gas lines. Exterior models are often the easiest swap when the gas line is already sized correctly.
Rinnai Tankless Water Heater Replacement in Los Angeles

We make sure your new Rinnai unit is installed correctly, extending its efficiency and lifespan. Our technicians know the installation requirements and venting options for Rinnai models, so the upgrade goes cleanly.
Tankless vs. Tank Water Heater Replacement Cost in Los Angeles, CA
When considering tankless water heater replacement in Los Angeles, CA, it is natural to compare costs. While the upfront installation of a tankless unit can be higher than a traditional tank, the long-term energy savings and longer lifespan often make it the more economical choice. We provide clear, upfront pricing for both options. That helps you make an informed decision based on your budget and hot water needs, with no surprises.
Condensing Tankless Replacement in Los Angeles
Condensing tankless units like the Navien NPE series or Rinnai Sensei reach efficiencies above 90 percent by recovering heat from exhaust gases. They vent through low-cost PVC and produce acidic condensate that must be neutralized and drained properly. We install a neutralizer cartridge and route the condensate line to an approved drain. Hot inland summers push water heaters and pool plumbing hard, while coastal salt air can corrode exposed metal fittings. Condensing units still save gas because they work year-round on showers, laundry and dishes. We explain the cost difference so you can decide if the efficiency gain is worth it.

Frequently Asked Questions About Tankless Water Heater Replacement in Los Angeles
A like-for-like gas tankless replacement usually runs $2,800 to $4,500 installed, depending on the brand and venting. Converting from a tank to tankless often costs $4,000 to $6,500 because of gas line and venting upgrades. We give you a written quote before any work starts.
FKM Plumbing installs and replaces all major reputable brands of tankless water heaters. Our preferred brands include Rinnai, Navien, Noritz and Rheem, as they are known for their reliability, energy efficiency and long-term performance. We can also order and install other brands based on your preference or home requirements.
A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, usually takes 4 to 8 hours. If you are converting from a traditional tank water heater, the process can take longer, possibly a full day, due to extra plumbing, gas or electrical changes required for proper installation and venting.
To protect the life and efficiency of your new tankless water heater, regular maintenance is crucial, especially in areas with hard water. This usually involves annual flushing to remove mineral buildup, checking the air filter, and inspecting gas and water connections. FKM Plumbing offers maintenance plans to help keep your unit in top condition.
Most jurisdictions in Southern California require a permit for water heater replacement, especially when gas piping or venting changes. We take care of permits where they are required.
New tankless water heaters typically come with a manufacturer's warranty, which usually covers the heat exchanger for 10 to 15 years and parts for 3 to 5 years. FKM Plumbing also provides a labor warranty on our installation work for your peace of mind. We will go over warranty details for your chosen unit during your consultation.
Common signs that your tankless water heater needs replacement include frequent error codes, inconsistent water temperature, reduced hot water flow or a complete lack of hot water. If your unit is over 15 to 20 years old and repairs are becoming frequent and costly, replacement is often the more sensible choice.
To prepare for tankless water heater replacement, make sure the area around your existing unit is clear and easy to reach for our plumbers. If possible, clear a path to the installation site and keep pets or children safely out of the work area. We will handle draining the old unit and all other technical preparations.
