Water heater installation cost by job.
Installed-labor pricing for Gastonia, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Gastonia, NC, where the median home was built in 1978, water heater installation costs typically range from $750 to $1,700 for a standard tank model and $1,700 to $4,300+ for a tankless unit. Local labor rates and the need for a permit under the North Carolina State Plumbing Code (based on the IPC) influence pricing.

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

Heat pump water heater mandates
New homes with electric water heaters larger than 55 gallons must use heat pump models, which may require additional space and electrical work.
