Water heater installation cost by job.
Installed-labor pricing for Marrero, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Marrero typically costs between $650 and $1,500 for a standard tank unit, and $1,500 to $3,700 or more for a tankless system. With many homes built around 1973, older plumbing and gas lines can add $250–$850 for new gas line installation.

Federal 25C tax credits (30%, up to $2,000) apply to qualifying heat pump models, helping offset upfront costs.
