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

Cold inlet water
Defiance's cold winters mean incoming water is very cold, reducing recovery rates and making gas heaters more efficient than electric.
