Strong Growth for Unvented Gas Heaters, Despite Hazards

While U.S. factory shipments were lower in 2007 than 2006 for nearly all residential appliances, according to the March 2008 issue of

Appliance magazine, factory shipments of unvented gas room heaters increased 43% during this period—from about 197,000 to 281,000 units. Dehumidifier shipments also increased significantly (38%), while shipments of refrigerators, clothes washers, and built-in dishwashers were all down (by 6.1%, 7.1%, and 3.6%, respectively).

EBN, among others, has argued that unvented gas heaters should be prohibited, since they introduce combustion gases to the home, reducing indoor air quality (see


Vol. 15, No. 5).
