Water heater replacement cost by type.
Installed prices for Bluffton, adjusted for local labor. Larger tanks and code upgrades move the number up.
Bluffton homeowners typically pay $800–$4,000 to replace a water heater, depending on type and labor. With a median home age of 15 years, many units are nearing the end of their lifespan. South Carolina requires a permit for water heater replacement, even for a like-for-like swap, and an expansion tank is mandatory if your system has a backflow preventer or check valve.
