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