THE FAMILY CUtCUS Ily liil Keltic "Billy says he doesn't hafta go to church tomorrow 'cause he's listening to 'Dial-A-Prayer' on the phone." Most gas furnaces waste much energy By EDWARD K. DcLONG WASHINGTON ( U P I ) - Government researchers say inefficient design, sizing and installation can waste from one- third to more than half the heat from a typical American homcov.T.cr's natural ^;;s fur nace system. As a result, says the Energy Kesearch and Development Administration, furnaces often burn more gas than necessary, and homeowners pay Hie price in higher fuel hills. A new report says ihe largest single source of heat waste is from uninsulated or leaking hot air ducts. The report is based on research al Ihe Oak Kidge N a t i o n a l Laboratory. Oak Ridge, Tenn., The report says waste also can result from oversize furnaces, improper fan cycle settings, and furnace designs that blow hot air out the chimney and suck cold outside air into the house. Researchers found even Ihe tiny flnmc of a pilot light wastes huge amounts of gas. The report concluded t h a t ".'ir to DO pur cent of ihe healing value of the fuel used in a typical residential gas furnace system is wasted." The fiS-page report includes recommendations to homeowners on to immediately reduce fuel hills and help conserve scarce natural gas by improving furnace system efficiency. It said furnace builders can cut gas consumption as much as one-third by Iwosting required efficiency levels, replacing open pilot flames with electric ignition systems, making all furnaces with sealed combustion chambers and using factory-set switches to turn fans off at 75 to 80 degrees. Industry standards now require ?5 per cent full load efficiency, a level which tests showed is being achieved. But the report said the standard could be boosted to 82 per cent without excessive technical problems. Pilot light flames use a cubic foot of gas an hour, the report said. It said the gas burned by a pilot during furnace standby periods, when the burner is not r u n n i n g , equalsS to 10 per of total fuel consumption in cold climates and 25 per cent or more in warm climates such as southern California. The report advises homeowners lo have the pilot light gas shut off in nonheatiny seasons. A nonscalcd furnace that draws combustion air from inside the house, as m a n y do.
