Water heater installation cost by job.
Installed-labor pricing for Parker, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Parker, South Carolina, typically costs between $600 and $1,400 for a standard tank unit and $1,400 to $3,400 or more for a tankless system. With a median home age of 56 years and a humid subtropical climate, many homes may need upgrades to meet current code, such as adding an expansion tank on closed systems. The local adoption of the 2021 South Carolina Plumbing Code (IPC) means permits are required for most installations, including simple replacements, which adds to the overall cost. Given the area's reliance on electric water heating, a heat pump water heater is a strong fit for efficiency, and homeowners can claim the federal 25C tax credit (30%, up to $2,000) for qualifying units.
