Residential Tankless Water Heater Replacement in Upland

Our team handles everything from safely disconnecting your old unit to installing the new tankless system. That includes all necessary gas and water line adjustments and venting changes to meet current codes.
Exterior Mount Tankless Units in Upland, 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 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 shield the water and gas lines. Exterior models are often the easiest swap when the gas line is already sized correctly.
Emergency Tankless Replacement in Upland, CA
A tankless heater that leaks from the heat exchanger or refuses to ignite can leave you with no hot water at all. We offer same-day emergency replacement for common models and can often get a unit installed the day you call. If your exact model is not in stock, we can sometimes do a temporary repair to restore hot water while the replacement ships. We shut off gas and water to stop any leak on arrival. Call (213) 871-0701 any time your tankless quits.
Recirculation Tankless Upgrades in Upland, CA
If you are tired of running the tap waiting 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. We program schedules so the pump runs only during your morning and evening peaks. That keeps gas use reasonable while saving thousands of gallons of wasted water a year. This upgrade is a favorite in long single-story ranch homes.
Tank to Tankless Conversions in Upland, 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 often 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. Plan for a conversion to take a full day.

Common signs that your tankless water heater needs replacement include repeated 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 economical choice.
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.
Most manufacturers offer 10 to 15 years on the heat exchanger and about 5 years on parts for residential use. We add our own labor warranty and register the unit on your behalf.
Yes. Softened or scale-treated water greatly reduces mineral buildup in the heat exchanger. We can install a scale-reduction filter if a full softener is not in your plans.
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 source and install other brands based on your preference or home requirements.
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.
Frequent error codes, fluctuating temperature, water leaking from inside the cabinet and a unit older than 15 years are common signs. If the heat exchanger is leaking, replacement is usually the better value.
