Automatic flue dampers

Book ·
OSTI ID:6144577
The use of automatic flue dampers for retrofit to gas and oil-fired furnaces and water heaters is reviewed. The energy saving potential, cost effectiveness and safety of automatic flue dampers are discussed. Alternative energy saving measures, other than automatic flue dampers, and specific test programs designed to evaluate the energy saving potential of automatic flue dampers and these other measures are also discussed. The study concludes that (1) automatic flue dampers can result in fuel savings; (2) the use of an automatic flue dampers is cost effective under certain conditions; and (3) properly tested, installed and maintained automatic flue dampers are safe. Recommendations of this study are that (1) National Center for Appropriate Technology (NCAT) should monitor laboratory tests and field tests results currently under way that are designed to quantify the energy savings of various furnace and water heater retrofit measures; and (2) disseminate the results of these programs for implementation in programs where NCAT provides technical assistance.
