Water heater replacement cost by type.
Installed prices for Florence, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Florence, South Carolina, water heater replacement costs vary by type and installation complexity. Tank gas models run $700–$1,750, tank electric $800–$1,900, tankless $1,300–$3,000+, and heat pump units $1,550–$3,500. Because the median home was built around 1980, many homes have older systems that may need code upgrades. Florence follows the 2021 South Carolina Plumbing Code (IPC), which requires a permit for replacements and an expansion tank if a backflow preventer or check valve is present. The humid subtropical climate and moderate winter inlet water temperatures make heat pump water heaters a strong fit, especially with the federal 25C tax credit covering 30% of cost up to $2,000.

What Affects Replacement Cost in Florence
Labor rates in Florence are moderate for a tier 3 market, but permit fees and code compliance (e.g., expansion tank installation) add $100–$300. Fuel type matters: electric units are more affordable to install than gas, but gas may have lower operating costs. Tankless and heat pump models require more labor and materials, raising the price. Home age (median 1980) often means outdated plumbing or electrical systems need upgrades, increasing the total.
