Water heater replacement cost by type.
Installed prices for Port Royal, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Port Royal, South Carolina, water heater replacement costs vary based on unit type, labor, and local code requirements. Typical installed prices range from $700–$1,700 for a tank gas unit, $750–$1,850 for tank electric, $1,250–$3,000+ for tankless, and $1,500–$3,400 for a heat pump model. With a median home age of about 20 years and a humid subtropical climate, many homes use electric water heaters, but heat pump units are a strong fit due to energy efficiency and the federal 25C tax credit (30% up to $2,000). Local permits are required under the South Carolina Plumbing Code (IPC 2021), and an expansion tank is needed on closed systems with backflow preventers. Tankless units are limited to 140°F output for domestic use.
