Analyzing the Design and Performance of a Retrofit Solar Thermal Combination DHW and Space Heating System (2010)
Submitted by Raquel Ponte Costa on April 7, 2015This paper comes from James Dontie of Gustavus Adolphus College. It reports on an analysis of a solar thermal combination domestic hot water and space heating system which was retrofitted into a residence in Minnesota.
The analysis attempts to distinguish between improvements to the residence’s heating system that came through using a solar thermal system instead of a conventional system, as compared to efficiencies that were the result of simply installing new equipment.
The paper finds that the system cut down on natural gas consumption by about 34% compared to the average of the previous four years, and that that number can largely be attributed to the system’s temperature control system.
