Water heater replacement cost by type.
Installed prices for Miamisburg, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Miamisburg, Ohio, where the median home was built in 1970, water heater replacement is a common home maintenance task. With a humid continental climate and cold winter inlet water, gas water heaters are the typical choice for their efficiency and lower operating cost. Installed prices for a standard tank gas unit range from $700 to $1,750, while tankless models run $1,300 to $3,000 or more. Heat pump water heaters qualify for a federal 30% tax credit (up to $2,000) and may also be eligible for Ohio's HEAR rebate (up to $1,750) once launched. Local plumbing permits are required, and expansion tanks are needed on closed systems. The Ohio Plumbing Code does not require a drain pan 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 Miamisburg 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.
