Water heater replacement cost by type.
Installed prices for North Potomac, adjusted for local labor. Larger tanks and code upgrades move the number up.
In North Potomac, Maryland, where the median home was built in 1987, many water heaters are nearing or past their expected lifespan. Replacing a water heater in this affluent community (median income $182,083) typically costs between $750 and $3,700, depending on the type and complexity. Given the humid subtropical climate and cold winter inlet water, a heat pump water heater is a strong fit, offering energy efficiency and eligibility for the federal 25C tax credit (30% up to $2,000). Local code requires a permit and inspection by a Maryland-licensed master plumber, and an expansion tank is needed on closed systems. Prices reflect labor, materials, and compliance with the International Plumbing Code.
