The kalan, or floored wood stove is ubiquitous in northern Luzon; illustrated at right are three popular types. Top: headed wood stove; middle: headless wood stove; bottom: fugon, or charcoal stove. The first two use wood and rice husks for fuel; the third only charcoal. Notice the three pronged pot supports on the first and third, while the headless stove has air holes instead.
