Given New Jersey’s humid continental / humid subtropical climate and gas water heating, high-efficiency gas is the sensible default for most South River 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.
