Water heater installation cost by job.
Installed-labor pricing for Fountain Inn, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Fountain Inn, SC, a standard tank water heater installation typically runs $700–$1,550, while a tankless unit costs $1,550–$3,900 or more, depending on gas line work ($250–$850). Most homes use electric water heating, and the humid subtropical climate means moderate winter inlet temperatures.

Local jurisdictions often enforce permits even for like-for-like swaps, so factor that into your project.
