Our team handles everything from safely disconnecting your old unit to installing the new tankless system. That includes all necessary gas and water line adjustments and venting changes to meet current codes.
Condensing Tankless Replacement in Ames
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. Iowa has long, cold winters and hot, humid summers, and those extremes put constant stress on pipes, water heaters, and sump pumps. 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.

Rinnai is a leading brand in the tankless water heater market, known for its quality and engineering.

Frequently Asked Questions About Tankless Water Heater Replacement in Ames
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.
A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, usually takes 4 to 8 hours. If you are converting from a traditional tank water heater, the process can take longer, possibly a full day, due to extra plumbing, gas or electrical changes required for proper installation and venting.
A direct swap typically takes four to six hours. A tank to tankless conversion with new gas and venting usually takes a full day.
DIY tankless water heater replacement is usually not recommended due to the complexity of gas lines, high-voltage electricity, water connections and venting requirements. Improper installation can lead to serious gas leaks, carbon monoxide poisoning, water damage or electrical hazards. It is best to hire a licensed and experienced plumber like KFR Plumbing.
Well-maintained tankless units can last 15 to 20 years. In hard water areas without regular descaling, heat exchangers can fail far sooner. Annual flushing makes the largest difference.
A standard tankless water heater replacement typically takes between 4 and 8 hours. This timeframe can vary based on whether we are replacing an existing tankless unit with a similar model or upgrading from a traditional tank water heater. A tank conversion can call for more extensive changes to gas lines, electrical or venting.
We do not recommend it. Gas line sizing, venting clearances and combustion testing call for training, and improper installs can void the warranty or create carbon monoxide hazards.
