Water heater replacement cost by type.
Installed prices for Potomac, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Potomac, Maryland, replacing a water heater typically costs between $800 and $4,000, depending on the type and installation complexity. With most homes built around 1977 and a median income of $218,710, many homeowners opt for heat pump water heaters, which qualify for a federal 25C tax credit of up to $2,000. Local plumbing work must be performed by a Maryland-licensed master plumber, and a final inspection is required before the unit is placed in service. Permits are mandatory, and an expansion tank is needed if your system has a check valve, pressure-reducing valve, or backflow preventer. The humid subtropical climate and cold winter inlet water make heat pump units a strong fit for energy efficiency.

Recommended unit for Potomac
Given Maryland’s humid subtropical climate and mixed water heating, heat-pump (hybrid) is the sensible default for most Potomac homes. 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.
