Water heater replacement cost by type.
Installed prices for Gastonia, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Gastonia, North Carolina, water heater replacement costs vary based on unit type and installation complexity. With many homes built around 1978, older systems often require replacement due to age or inefficiency. Typical installed prices range from $750–$1,900 for gas tank units, $850–$2,100 for electric tank, $1,400–$3,300+ for tankless, and $1,700–$3,800 for heat pump models.

Local permits are required under the North Carolina State Plumbing Code, and expansion tanks are needed on closed systems with backflow prevention.
