July 21, 2011, Coolidge, GA – St. Elizabeth Hospital in Appleton, Wisconsin, is one of the few hospitals in the United States to achieve an energy performance rating in the top 25% of facilities nationwide, earning it the prestigious ENERGY STAR designation from the U.S. Environmental Protection Agency.

Working closely with Affiliated Engineers, Boldt Construction, and Tweet/Garot Mechanical to design and install the energy-efficient central utility plant, St. Elizabeth’s selected the Hurst Boiler Scotch Marine Series 500 system to help meet its green healthcare initiative goals.

“We selected two 700-hp Hurst scotch marine, four pass, wetback boilers with high performance Riello burners and integrated plant master controls,” says Mike Sturdivant, executive vice-president of Tweet/Garot Mechanical. “This package provided a very competitive first cost, the best efficiency, and lowest long-term operating cost.”

Ron Piotrowski, plant operations for St. Elizabeth Hospital, says, “The high turndown Riello burners on our Hurst boilers allow the system to run efficiently down to 10% of full firing rate.”
Sturdivant adds that the efficient turndown of the new primary boilers will eliminate the need to purchase and install a separate smaller summer boiler.
