Water heater installation cost by job.
Installed-labor pricing for Largo, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Largo, Maryland typically costs between $750 and $1,700 for a standard tank unit, and $1,700 to $4,200+ for a tankless model. With a median home built in 1983 and cold winter inlet water, many homes benefit from upgrading to a heat pump water heater, which qualifies for a federal 30% tax credit up to $2,000. All plumbing work must be performed by a Maryland-licensed master plumber, and a permit is required. A final local inspection checks T&P discharge, venting, and connections. An expansion tank is needed on closed systems, which are common with check valves or PRVs. These factors influence the final cost and timeline.

Recommended unit for Largo

Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.
