Water heater installation cost by job.
Installed-labor pricing for Conway, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Conway, South Carolina, water heater installation costs typically range from $650 to $1,500 for a standard tank unit, and $1,500 to $3,800+ for a tankless system. Adding a new gas line, if needed, runs $250–$850. Most homes here use electric water heaters, and with a median home age of about 35 years, many existing units are due for replacement. Conway follows the South Carolina Plumbing Code (2021 IPC), which requires a permit for water heater replacements—even simple like-for-like swaps. Given the humid subtropical climate and moderate winter inlet water temperatures, a heat pump water heater is a strong fit, and the federal 25C tax credit (30% up to $2,000) can offset costs for qualifying models.

Water Heater Installation in Conway, explained.
What affects installation cost in Conway?
The type of water heater—tank vs. tankless—is the main price driver. Tankless units cost more upfront but may save energy. Adding a gas line for a gas unit increases cost. Permit fees and labor rates in Conway also factor in. Older homes may need code upgrades, like an expansion tank if a closed system is present. Choosing a heat pump water heater qualifies for a federal tax credit, reducing net cost.
Common water heater installation issues in Conway
Permit requirements
Conway requires a permit for water heater replacements, even like-for-like. Failing to pull a permit can lead to fines or issues when selling the home.
Expansion tank needed on closed systems
If your home has a backflow preventer or check valve, the code requires an expansion tank to prevent pressure buildup. This adds to installation cost.
Older home wiring or gas line upgrades
Many Conway homes built around 1991 may have outdated electrical panels or undersized gas lines, requiring upgrades to support a new water heater.
