Gas Tankless Water Heater Replacement in Baton Rouge

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 as soon as we arrive.

Like-for-Like Tankless Swaps in Baton Rouge
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 quickest 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 finished in four to six hours.
Electric Tankless Water Heater Replacement in Baton Rouge, LA
For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a viable choice. Beau's Plumbing offers electric tankless water heater replacement services in Baton Rouge, LA. This often involves careful 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 correctly, providing on-demand hot water without the need for gas lines.
Condensing Tankless Replacement in Baton Rouge
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 inexpensive 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. Around Baton Rouge, attic and crawlspace heat can speed up wear on supply lines, drain pans, and any plastic piping in those spaces. 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.
