Water heater replacement cost by type.
Installed prices for Rochester, adjusted for local labor. Larger tanks and code upgrades move the number up.
Water heater replacement in Rochester, New Hampshire, typically costs between $750 and $3,800 depending on the type of unit and installation complexity. With most homes built around 1977, many older systems are due for an upgrade, and the cold northern climate means your new heater must handle very cold inlet water. New Hampshire requires all plumbing work to be done by a state-licensed plumber, and a permit and inspection are mandatory. For energy savings, a heat pump water heater is recommended, especially since the federal 25C tax credit covers 30% of the cost up to $2,000.
