Water heater replacement cost by type.
Installed prices for Derry, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Derry, New Hampshire, water heater replacement costs typically range from $700 to $3,600 depending on the type and installation complexity. With a median home age of 45 years, many homes have older units that need upgrading. Local code requires a permit and inspection, and all work must be done by a state-licensed plumber.
