Water heater installation cost by job.
Installed-labor pricing for Falls Church, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Falls Church, Virginia, where the median home was built in 1971, many older homes need water heater replacements. Typical installed costs for a standard tank water heater range from $750 to $1,700, while tankless installations run $1,700 to $4,200 or more, plus $275 to $950 for a new gas line. Virginia requires a permit for any water heater replacement, even a like-for-like swap, and an expansion tank is needed on closed systems. Given the area's moderate winter inlet water and mostly electric heating, a heat-pump water heater is a strong fit, and the federal 25C tax credit covers 30% of the cost up to $2,000.
