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