Water heater replacement cost by type.
Installed prices for Dover, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Dover, Ohio, water heater replacement costs typically range from $650 to $3,300 depending on the unit type and installation complexity. With a median home built in 1967 and cold winters, many homes use gas water heaters, which are a strong fit given the local climate and fuel availability. Ohio Plumbing Code requires a permit for replacement, and an expansion tank is needed if a check valve or pressure-reducing valve is present. Drain pans are not required unless previously installed.

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