An Analysis of the Decay Rate of Combustion Gases in U.S.Homes Using Unvented Gas Fireplaces
Indoor concentrations of combustion products were measured in 30 homes in which unvented hearth-type appliances were used. In many homes the usage patterns were such that there was a clear exponential decay of the combustion gases after the appliance was shut off. This allowed for estimation of the apparent decay rates. This paper focuses on the results of this decay analysis in the homes on which this analysis was possible. The different rates of decay for the various gases are presented,and differences between the decay rates are discussed. Limited results from a national survey on the use of these appliances are presented to indicate the choices made by consumers with regard to unvented hearth appliances,both from energy and indoor environment standpoints. A brief summary of the overall concentration results from the study,which are the primary subject of another paper,are provided for context.
