Water heater replacement cost by type.
Installed prices for Hanahan, adjusted for local labor. Larger tanks and code upgrades move the number up.
Hanahan homeowners replacing a water heater face costs shaped by local factors. With a median home age of 38 years, many homes have older units that may need code updates. South Carolina requires a permit for water heater replacements, and the 2021 IPC code applies. The humid subtropical climate and moderate winter inlet water temperatures mean heat pump water heaters are a strong fit, especially with the federal 25C tax credit covering 30% of cost up to $2,000. Typical installed prices range from $700–$1,750 for gas tank, $800–$1,950 for electric tank, $1,350–$3,100+ for tankless, and $1,600–$3,500 for heat pump. Labor, permit fees, and potential expansion tank requirements (if a closed system) affect the final price.
