Why Choose FKM Plumbing for Tankless Water Heater Replacement in Pasadena, CA?
Municipal water across much of Southern California is hard, leaving chalky scale on faucets, showerheads, and inside water heater tanks. 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 stands up to your local water supply.
- Increased Lifespan, Modern tankless water heaters often last much longer than conventional tank models, offering a better long-term investment.
- Scale Protection, Every install includes isolation valves so the heat exchanger can be descaled without cutting into the pipes.
- Energy Savings, Tankless water heaters only heat water when you need it, which can noticeably reduce energy use compared to traditional tank models, a big plus for Southern California utility bills.

Recirculation Tankless Upgrades in Pasadena, CA
If you are tired of running the tap while you wait for hot water, a tankless with a built-in recirculation pump can bring heat to the fixture in seconds. Navien A series and Rinnai units with internal pumps can use a dedicated return line or a crossover valve under the farthest sink.

This upgrade is a favorite in long single-story ranch homes.

Tankless vs. Tank Water Heater Replacement Cost in Pasadena, CA
When considering tankless water heater replacement in Pasadena, CA, it is natural to compare costs. While the initial 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 cost-effective 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.
Exterior Mount Tankless Units in Pasadena, 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 wear out plastic covers and wiring over time. On an occasional cold night, covering backflow preventers and outdoor valves is typically enough 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 simplest swap when the gas line is already sized correctly.
Tank to Tankless Conversions in Pasadena, CA
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units usually need a larger gas line, often three quarter inch or bigger, plus new venting. We check your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Expect a conversion to take a full day.

Frequently Asked Questions About Tankless Water Heater Replacement in Pasadena
A like-for-like gas tankless replacement typically 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.
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 discuss warranty details for your chosen unit during your consultation.
Well-maintained tankless units can last 15 to 20 years. In hard water areas without regular descaling, heat exchangers can fail far sooner. Annual flushing makes the largest difference.
With proper installation and regular maintenance, a new tankless water heater typically lasts 20 to 25 years. This is significantly longer than traditional tank water heaters, which usually last 10 to 15 years. Regular flushing and descaling can help extend the life of your tankless unit, especially in hard water areas.
To protect the life and efficiency of your new tankless water heater, regular maintenance is crucial, especially in areas with hard water. This typically 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.
We do not recommend it. Gas line sizing, venting clearances and combustion testing require training, and improper installs can void the warranty or create carbon monoxide hazards.
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 away from the work area. We will handle draining the old unit and all other technical preparations.
Yes, you can absolutely replace a traditional tank water heater with a tankless unit. This is a common upgrade for homeowners looking for better energy efficiency and endless hot water. However, it often requires changes to gas lines, venting and possibly electrical wiring, making professional installation important for safety and performance.
