Water heater installation cost by job.
Installed-labor pricing for Arlington, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Arlington, VA, water heater installation costs typically range from $1,000 to $2,200 for a standard tank unit and $2,200 to $5,500+ for a tankless model. Labor rates reflect the DC metro area, and a permit is required even for like-for-like swaps under the Virginia Plumbing Code. With a median home age of 50 years, many homes need upgrades to meet current code, such as an expansion tank on closed systems. The humid subtropical climate and moderate winter inlet water make heat-pump water heaters a strong fit, especially with the federal 25C tax credit covering 30% of cost up to $2,000. Virginia's state rebate program is not yet available.
