Recommended unit for Plainfield
Given Indiana’s cold northern humid continental climate and gas water heating, tank or tankless is the sensible default for most Plainfield 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.
