Recommended unit for Los Alamos
Given New Mexico’s arid high desert climate and gas water heating, tank or tankless is the sensible default for most Los Alamos 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.
