Water heater installation cost by job.
Installed-labor pricing for Charleston, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Charleston, WV, where the median home was built in 1956, many older homes need water heater replacements. Standard tank installation typically runs $700–$1,600, while tankless units cost $1,600–$3,900+. Local labor rates and the need for permits under the International Plumbing Code influence pricing.

The federal 25C tax credit offers up to $2,000 for heat pump models, making them a more affordable long-term option.

Recommended unit for Charleston
Given West Virginia’s humid subtropical / mountainous climate and mixed water heating, tank or tankless is the sensible default for most Charleston homes. Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.
