Installed-labor pricing for Somerset, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Somerset, New Jersey, typically costs between $750 and $1,700 for a standard tank unit and $1,700 to $4,200+ for a tankless model, plus $275–$950 for a new gas line if needed. With a median home built in 1979, many homes have older systems that require replacement.

The federal 25C tax credit offers 30% back (up to $2,000) for qualifying heat pump water heaters, but gas units remain common due to local fuel availability.
