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.

Tank to Tankless Conversions in Santa Ana, 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.
Gas Tankless Water Heater Replacement in Santa Ana
Many homes in Santa Ana rely on natural gas for water heating, and gas tankless units are a very efficient option.

We prioritize safety. All gas connections and combustion air requirements meet Southern California and local codes, heading off potential hazards and maximizing efficiency.
Tankless vs. Tank Water Heater Replacement Cost in Santa Ana, CA
When considering tankless water heater replacement in Santa Ana, CA, it is natural to compare costs.

To prepare for tankless water heater replacement, make sure the area around your existing unit is clear and accessible 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.
Repeated 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 typically the better value.
FKM Plumbing installs and replaces all major trusted 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.
To protect the life and efficiency of your new tankless water heater, regular maintenance is crucial, especially in areas with hard water.

Yes, you can absolutely replace a traditional tank water heater with a tankless unit. This is a common upgrade for homeowners seeking better energy efficiency and endless hot water. However, it often requires changes to gas lines, venting and possibly electrical wiring, making professional installation essential for safety and performance.
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.
