An increasing emphasis on variable speed pumping as a means to save energy in commercial buildings has provided engineers with many paths to efficient hydronic system design.
Beginning Jan. 27, 2020, clean water pumps sold in the United States must achieve a minimum energy rating of 1.0 as outlined in the Energy Conservation Standards for Pumps established by the U.S. Department of Energy (DOE) and adopted by Natural Resources Canada.
Best efficiency staging achieved with technologically advanced controllers and variable speed drives.
