Water heater replacement cost by type.
Installed prices for North Plainfield, adjusted for local labor. Larger tanks and code upgrades move the number up.
In North Plainfield, where the median home was built in 1953, water heater replacement is a common upgrade. Local installed prices for a gas tank water heater typically range from $700 to $1,800, while electric tank models run $800 to $1,950.
