Water heater replacement cost by type.
Installed prices for Gretna, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Gretna, Louisiana, water heater replacement costs typically range from $600–$1,550 for a tank gas unit, $700–$1,700 for tank electric, $1,150–$2,700+ for tankless, and $1,400–$3,100 for a heat pump model.
