"An important but often overlooked factor influenc ing fireplace efficiency is the choice of fuel," said Ardis Hutchins, extension housing specialist. Hard .voods, such as hickory, oak, ash and apple, burn longer and more stead ily, producing more hours of heat. Softwoods, such as pine, ignite more readily, but produce less total heat per log, she explained. "It's important to burn wood that has been thoroughly seasoned," she added. According to tests con ducted by the U.S. Forest Product Laboratory, it's possible to get as much as 44 percent more heat from a log by simply letting it air dry before burning. "Turning down the thermostat and closing the door to the room where the fire is burning will also keep heat loss to a minimum," Hutchins said. Homeowners are pur chasing equipment for their fireplace to further increase heating efficiency. This equipment ranges from the more expensive air blowers to the popular tempered glass screens. The specialists said the following are among those items avail able: Tubes or hollow grates can be placed in the fire place to provide additional heat by air circulation. Some of these units rely on natural air flow, while others use a fan. Heat-circulating units can be inserted into the present firebox. These units draw heated air from the fire, up ward to form a current by the underside of a V-shaped duct. The delay causes a transfer of heat energy that would otherwise go up the flue. Tempered glass screens or tight-fitting glass doors greatly reduce the amount of heat loss up a chimney while the damper is open and the fire is dying out. Greatest savings occur when the closed doors control the loss of heat overnight. A tight-fitting metal door or sheet of asbestos may be used. Bypass dampers can be installed in the fireplace box to radiate heat from the fire back into the room. The metal baffle, hung below the damper re-radiates heat back into the room. "Those persons who use their fireplace on a regular basis should build a good, hot fire at least weekly to burn out deposits of soot and creosote in the chimney," according to Gerald Bodman, UNLexten sion engineer. wm KINKO'S 330 N. 13th Half Block From Love Library Phone 475-COPY First lesson: Bonded Bourbon is so unique that it took an act of Congress (in 1897) to establish the standards for Old Grand-Dad and other Bonded whiskeys. 100 is perfect.
