Exterior Mount Tankless Units in Clovis, 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. Mountain and foothill homes in Northern California see real winters, so pipes there need insulation, heat tape, or proper draining when a cabin sits empty. 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 simplest swap when the gas line is already sized correctly.

Commercial Tankless Replacement in Clovis
Restaurants, salons and small offices often use multiple tankless units linked together on a rack system. When one or more units fail, we replace them and rebalance the cascade controls so they split the load. We check gas pressure under full demand, since commercial racks can draw more than 600,000 BTU combined. Scheduling is easy to work around, so we can work after hours and keep your business open. We also set up a descaling schedule suited to your water usage.
Navien Tankless Water Heater Replacement in Clovis, CA
Navien tankless water heaters are popular for their condensing technology, offering high efficiency and performance. When it is time for a Navien tankless water heater replacement in Clovis, CA, you can count on FBL Plumbing. We have broad experience with Navien's advanced systems, including their combination boiler and water heater units. Our installation process focuses on optimizing your new Navien's performance, so you benefit from its energy-saving features and reliable hot water output.
Tank to Tankless Conversions in Clovis, 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.
Recirculation Tankless Upgrades in Clovis, 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. 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 popular in long single-story ranch homes.
Electric Tankless Water Heater Replacement in Clovis, CA
For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a practical choice. FBL Plumbing offers electric tankless water heater replacement services in Clovis, CA. This often involves close assessment of your home's electrical panel capacity, as these units require significant amperage. We make sure your new electric tankless unit is installed safely and effectively, providing on-demand hot water without the need for gas lines.

Our technicians are familiar with the installation requirements and venting options for Rinnai models, so the upgrade goes smoothly.

Like-for-Like Tankless Swaps in Clovis
When your existing tankless has a cracked heat exchanger or a failed control board that is not worth repairing, a direct replacement is often the fastest fix. We match the new unit to your current gas line, venting type and mounting location whenever possible. Many Rinnai and Navien models share similar footprints, which keeps wall patching to a minimum. We also replace the old service valves if they are corroded or seized. Most like-for-like swaps are done in four to six hours.
