Water heater replacement cost by type.
Installed prices for Clemson, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Clemson, South Carolina, water heater replacement costs vary based on unit type and local labor rates. Tank gas replacements typically run $600–$1,550, tank electric $700–$1,700, tankless $1,150–$2,700+, and heat pump models $1,400–$3,100. With a median home age of 36 years and a humid subtropical climate, many homes may have older units nearing end of life. Permits are required under the South Carolina Plumbing Code (2021 IPC), and an expansion tank is needed if a backflow preventer or check valve is present. Given the area's moderate winter inlet water temperature and mostly electric water heating, a heat pump water heater is a strong fit and qualifies for the federal 25C tax credit (30%, up to $2,000).

With a median home age of 36 years, many water heaters are past their 10–15 year lifespan, leading to leaks or failure.
