Water heater installation cost by job.
Installed-labor pricing for Moncks Corner, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Moncks Corner typically costs between $700 and $1,600 for a standard tank unit, and $1,600 to $4,000+ for a tankless system. Local labor rates reflect the area's median household income of $83,079, and permits are required under the South Carolina Plumbing Code (2021 IPC).
