Water heater replacement cost by type.
Installed prices for Alexandria, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Alexandria, VA, water heater replacement costs typically range from $1,000 to $4,900, depending on the unit type. With a median home age of 53 years, many older homes have tank water heaters nearing the end of their lifespan. The city's 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. Virginia requires a permit for all water heater replacements, even like-for-like swaps, and expansion tanks are needed on closed systems. Local labor rates reflect the area's median household income of $113,179, and most homes use electric water heating, so electric or heat pump units are common.
