Water heater replacement cost by type.
Installed prices for Brentwood, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Brentwood, Tennessee, where the median home was built in 1995, many water heaters are approaching or past their expected lifespan. Replacing a water heater in this affluent suburb of Nashville typically costs between $800 and $4,000, depending on the type and installation complexity. Local labor rates reflect the area's high median household income of $181,576, and permits are required under Tennessee's adoption of the International Plumbing Code.
