Development of sizing guidelines for vent-free supplemental heating products. Topical report, June 1995-March 1996
Millions of consumers currently use vent-free gas heating product (blue flame, infrared and hearth product). Questions sometimes arise regarding the impact of hearth products on IAQ because of the unique use of logs above the flame. Unacceptable concentations of some combustion products may be found in the living space if the vent-free products are improperly sized for installation, or if they are installed or operate incorrectly. This potential was shown by a 1988 GEOMET study sponsored by GRI. A computer simulation model was developed and verified to simulate the impact on IAW for three different house structures (loose, average and tight), characterized by different wall `U` factors (heat losses) and air change rates. The simulations were made for five DOE heating regions of the U.S., using 1000 hour temperature for the region as a reference temperature. The model verification consisted of checking the calculated results with actual experiments conducted in two research houses: AGAR Research House and GRI GARD House.
