Installed prices for Franklin, adjusted for local labor. Larger tanks and code upgrades move the number up.
Franklin, Kentucky homeowners considering water heater replacement face costs shaped by local labor rates, permit requirements, and climate conditions. With a median home built in 1977, many homes have aging tank units that need upgrading. Typical installed prices in Franklin range from $650–$1,600 for a gas tank, $700–$1,750 for electric tank, $1,200–$2,800+ for tankless, and $1,450–$3,200 for heat pump models.
