Five solar panels were installed in a location on the roof of the store ensure no obstruction to sunlight access, again maximizing efficiency. With 60-70% of the hot water load for the grocery store being provided by this drain-back system, it is expected that there will be a $1,400 saved in the first year alone.
Due to its freezing and overheating prevention, the drain-back system was a great choice for replacing Bloomingfoods's older, 100-gallon commercial water heater. Hot water is needed for in-store cleaning, food production, and other services throughout the store. Whether or not they know it, this system is a great help and asset for the 8,300 member owners and the 1,000+ people who walk in the door!
Many thanks to the great folks at Bloomingfoods for a job well done. We look forward to seeing what else is in store in the future!
Bloomingfoods was a 2010 recipient of a Solar Thermal Grant from the Indiana Office of Energy Development. This program is funded through the State Energy Program by the U.S. Department of Energy.
