Water heater installation cost by job.
Installed-labor pricing for Ashburn, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Ashburn, VA, a typical water heater installation costs between $800 and $1,800 for a standard tank unit, while a tankless installation runs $1,800 to $4,600 or more. Adding a new gas line can cost $300–$1,000. Because Ashburn is in climate zone 3 with moderate winter inlet water temperatures, heat pump water heaters are a strong fit, especially with the federal 25C tax credit covering 30% of cost up to $2,000. Virginia requires a permit for all water heater replacements, even like-for-like swaps, and expansion tanks are needed on closed systems. Labor rates reflect the area's high median income of $147,192, and most homes built around 1999 may need updates to meet current code.
