Navien Tankless Water Heater Replacement in Bossier City, LA
Navien tankless water heaters are popular for their condensing technology, delivering high efficiency and performance. When it is time for a Navien tankless water heater replacement in Bossier City, LA, you can count on Beau's Plumbing. We have extensive experience with Navien's advanced systems, including their combination boiler and water heater units. Our installation process focuses on dialing in your new Navien's performance, so you benefit from its energy-saving features and reliable hot water output.

Condensing Tankless Replacement in Bossier City
Condensing tankless units like the Navien NPE series or Rinnai Sensei reach efficiencies above 90 percent by capturing 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. Long, hot summers and heavy humidity are the main stress on plumbing in Louisiana, driving condensation, mold, and overworked water heaters. 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 the price.

Frequently Asked Questions About Tankless Water Heater Replacement in Bossier City
A like-for-like gas tankless replacement usually 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.
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 for you.
New tankless water heaters typically come with a manufacturer's warranty on the heat exchanger, usually 10 to 15 years, and on parts, usually 3 to 5 years. Beau's Plumbing also provides a warranty on our installation workmanship. We will go over all warranty details with you before your replacement so you understand your coverage.
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.
DIY tankless water heater replacement is generally not recommended due to the complexity of gas lines, high-voltage electricity, water connections and venting requirements. Improper installation can lead to dangerous gas leaks, carbon monoxide poisoning, water damage or electrical hazards. It is best to hire a licensed and experienced plumber like Beau's Plumbing.
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 sensible choice.
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.
Yes. Softened or scale-treated water sharply reduces mineral buildup in the heat exchanger. We can install a scale-reduction filter if a full softener is not in your plans.
