Water heater installation cost by job.
Installed-labor pricing for Alexandria, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Alexandria, 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 system. With a median home age of 53 years, many homes need updates to meet the Virginia Plumbing Code, which requires a permit for all replacements and an expansion tank on closed systems. The humid subtropical climate and moderate winter inlet water temperatures make heat pump water heaters a strong fit, especially with the federal 25C tax credit covering 30% of the cost up to $2,000. Local labor rates reflect the high median household income of $113,179, and adding a new gas line for tankless units can cost $375–$1,250.
