Tank to Tankless Conversions in Mount Pleasant, SC

Frequently Asked Questions About Tankless Water Heater Replacement in Mount Pleasant
The cost of tankless water heater replacement in Mount Pleasant, SC typically ranges from $3,000 to $6,000, depending on the unit's capacity, brand, complexity of installation, such as converting from a tank model, and any needed electrical or gas line upgrades. This price usually includes the unit itself and labor. We provide a written, upfront quote after a thorough assessment of your home.
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 protect code compliance and warranty validity.
A direct swap typically takes four to six hours. A tank to tankless conversion with new gas and venting typically takes a full day.
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.
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, if you are upgrading from an existing tankless unit, typically 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.
Yes, you can certainly replace a traditional tank water heater with a tankless unit. This is a common upgrade for homeowners looking for 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.
New tankless water heaters usually come with a manufacturer's warranty on the heat exchanger, usually 10 to 15 years, and on parts, usually 3 to 5 years. KBN 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.
