Given Washington’s cool marine / temperate climate and electric water heating, heat-pump (hybrid) is the sensible default for most Bainbridge Island 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.
