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