Gas Tankless Water Heater Replacement in Reston
Many homes in Reston rely on natural gas for water heating, and gas tankless units are a very efficient option. Our gas tankless water heater replacement service includes careful inspection of your existing gas lines, proper sizing of new gas lines if needed, and secure venting to the outdoors. We prioritize safety. All gas connections and combustion air requirements meet Virginia and local codes, preventing potential hazards and maximizing efficiency.
Condensing Tankless Replacement in Reston
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 low-cost 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. Summer humidity causes condensation on cold water lines and in crawlspaces, which can speed up corrosion and invite mold. 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.
