Water heater replacement cost by type.
Installed prices for Arlington, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Arlington, Virginia, replacing a water heater typically costs between $1,000 and $4,900 depending on the type and complexity. With a median home age of about 50 years, many homes have older systems that may require updates to meet current Virginia Plumbing Code. 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. Labor rates reflect the D.C. metro area, and permits are required for all replacements, even like-for-like swaps. Expansion tanks are needed on closed systems, but drain pans are not required unless previously installed.
