Water heater installation cost by job.
Installed-labor pricing for Gantt, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Gantt, South Carolina typically costs $600–$1,400 for a standard tank unit and $1,400–$3,400+ for a tankless system. With a median home age of about 54 years, many homes may need updates to meet the South Carolina Plumbing Code (2021 IPC), including permits and expansion tanks on closed systems. Given the humid subtropical climate and moderate winter inlet water, a heat pump water heater is a strong fit for energy savings, and the federal 25C tax credit (30% up to $2,000) can offset costs. Local labor rates reflect the area's median income of $43,796, and permits are required for all replacements in many jurisdictions.
