Water heater installation cost by job.
Installed-labor pricing for Carthage, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Carthage, MO, where the median home was built in 1971, many older homes need water heater replacements. A standard tank installation typically runs $600–$1,400, while tankless units cost $1,400–$3,400+. Because Carthage has cold winters and uses mostly gas water heating, a gas unit is a strong fit.

The federal 25C tax credit offers 30% back (up to $2,000) on qualifying heat pump water heaters, but gas remains the recommended choice for this area.
