Water heater installation cost by job.
Installed-labor pricing for North Potomac, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in North Potomac, Maryland, typically costs between $750 and $1,700 for a standard tank unit, and $1,700 to $4,200+ for a tankless system. With most homes built around 1987, many older units may need replacement. Maryland requires a permit and a licensed master plumber for installation, plus a final inspection to ensure T&P discharge, venting, and connections meet code. Given the cold winter inlet water and humid subtropical climate, a heat-pump water heater is a strong fit for energy efficiency, and the federal 25C tax credit (30%, up to $2,000) can offset costs. Local homeowners should plan for permit fees and potential expansion tank installation if a closed system is present.
