Water heater installation cost by job.
Installed-labor pricing for Aiken, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Aiken, SC typically costs between $700 and $1,650 for a standard tank unit, while tankless models run $1,650 to $4,100 or more, depending on gas line work. With many homes built around 1985, older plumbing and electrical systems may require upgrades during installation. South Carolina follows the 2021 International Plumbing Code, so a permit is required for most replacements, and an expansion tank is needed if a backflow preventer is present. Given the humid subtropical climate and moderate winter inlet water, a heat pump water heater is a strong fit and qualifies for the federal 25C tax credit (30% up to $2,000).
