Water heater installation cost by job.
Installed-labor pricing for Morristown, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Morristown, New Jersey, water heater installation costs typically range from $750 to $1,700 for a standard tank unit, and $1,700 to $4,200+ for tankless. With many homes built around 1965, older plumbing and gas lines may require upgrades, adding $275–$950 for a new gas line.

Permits are required under the Uniform Construction Code, and an expansion tank is needed on closed systems per the National Standard Plumbing Code. The federal 25C tax credit offers up to $2,000 for qualifying heat pump water heaters, but gas units remain common due to lower upfront costs and local fuel availability.
