Water heater replacement cost by type.
Installed prices for Marietta, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Marietta, Ohio, water heater replacement costs typically range from $600 to $1,700 for tank units and $1,150 to $3,100 for tankless or heat pump models. With a median home age of 68 years, many homes have older water heaters that may need replacement. The city's humid continental climate means cold winter inlet water, which can affect heating efficiency. Most homes use gas water heating, making gas tank units a common and practical choice. Local permits are required under the Ohio Plumbing Code, and expansion tanks are needed on closed systems. A drain pan is not required for replacements where none existed before.

Given Ohio’s humid continental (cold winters) climate and gas water heating, high-efficiency gas is the sensible default for most Marietta 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.
