Gas Tankless Water Heater Replacement in Florence
Many homes in Florence rely on natural gas for water heating, and gas tankless units are a highly 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.

Condensing Tankless Replacement in Florence
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. Warm weather for most of the year means water heaters, irrigation lines and outdoor fixtures in South Carolina see year-round use with little seasonal rest. 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.

The cost for tankless water heater replacement in Florence, SC typically ranges from $3,000 to $6,000, depending on the unit's brand, capacity, fuel type (gas or electric) and any needed changes to gas lines, electrical or venting. This estimate includes both the new unit and professional installation. We always provide a detailed quote upfront after assessing your needs.
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.
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 typically the better value.
KBN Plumbing installs and replaces all major reputable brands of tankless water heaters. Our preferred brands include Rinnai, Navien, Noritz and Rheem, as they are known for their reliability, energy efficiency and long-term performance. We can also order and install other brands based on your preference or home requirements.

Tankless water heater replacement is a complex job that involves gas lines, electrical wiring, water connections and venting. It is highly recommended to hire a licensed professional like KBN Plumbing due to the safety risks and potential for improper installation, which can lead to leaks, gas hazards or inefficient operation. Professionals also ensure code compliance and warranty validity.
Yes, you can certainly replace a traditional tank water heater with a tankless unit. This is a common upgrade for homeowners seeking better energy efficiency and endless hot water. However, it often requires changes to gas lines, venting and possibly electrical wiring, making professional installation important for safety and performance.
Well-maintained tankless units can last 15 to 20 years. In hard water areas without regular descaling, heat exchangers can fail much sooner. Annual flushing makes the biggest difference.
