Condensing Tankless Replacement in Prairieville
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. Around Prairieville, attic and crawlspace heat can accelerate 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.

That includes all necessary gas and water line adjustments and venting changes to meet current codes.
Tankless vs. Tank Water Heater Replacement Cost in Prairieville, LA

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 share the load.
