Energy efficient masonry fireplace. Design and performance evaluation

Technical Report:

Abstract

This report contains the findings of an extensive research investigation into the design and performance of the masonry fireplace. It contains a comprehensive survey of literature relating to the study of the performance and efficiency of open type fireplaces. All those papers which were deemed relevant were annotated and contained in a bibliography. From the literature, and applying common sense, an improved design for the masonry fireplace was formulated and a test fireplace built along with a conventional type. A series of twenty tests was performed on these fireplaces and all of the parameters identified in the literature deemed to be important, such as room air temperature, radiation output and heat losses, were measured. A detailed analysis of the data revealed that the modified design does in fact perform more efficiently than the conventional design. In addition to redesigning and testing the fireplace, the investigations covered the requirements for replacement air and how this air could be introduced into the fireplace in a safe and efficient manner. The problem of exfiltration was also examined and in particular the various advantages and disadvantages of glass doors and chimney top dampers were investigated. Glass doors were found to reduce the amount of  More>>

In addition to redesigning and testing the fireplace, the investigations covered the requirements for replacement air and how this air could be introduced into the fireplace in a safe and efficient manner. The problem of exfiltration was also examined and in particular the various advantages and disadvantages of glass doors and chimney top dampers were investigated. Glass doors were found to reduce the amount of sensible heat lost in the flue gases but at the same time they drastically reduced the radiant energy emitted by the fireplace. Recommendatins for retrofitting existing fireplaces are made but only a few of them were tested in this investigation. Finally, the different methods for rating the efficiency of open type fireplaces are reviewed in some detail. The best and most realistic method for a masonry fireplace, electric co-heating, is discussed in depth. 40 refs., 58 figs., 69 tabs.}
