Water heater replacement cost by type.
Installed prices for Falls Church, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Falls Church, Virginia, where the median home was built in 1971, water heater replacement is a common upgrade for aging systems. Local installed pricing for a tank gas unit ranges from $750 to $1,850, tank electric $850–$2,100, tankless $1,400–$3,300+, and heat pump models $1,700–$3,700. Given the area's humid subtropical climate and moderate winter inlet water temperatures, a heat pump water heater is a strong fit, especially with the federal 25C tax credit covering 30% of cost up to $2,000. However, Virginia's state-level Home Energy Rebate is still pending approval, so no additional state rebates are available yet. Permits are required for all replacements, even like-for-like swaps, and expansion tanks are needed on closed systems per the Virginia Plumbing Code. Falls Church's high median income of $164,536 means homeowners often invest in efficient upgrades, but pricing still varies based on unit type, labor, and any necessary code updates.
