Wisconsin hospital uses energy-efficient boiler

St. Elizabeth Hospital in Appleton, Wis., earns the Energy Star designation from the U.S. Environmental Protection Agency as part of a green healthcare initiative.


St. Elizabeth Hospital, part of Affinity Health System, in Appleton, WISt. Elizabeth Hospital, part of Affinity Health System, in Appleton, Wis., is one of the few hospitals in the U.S. to achieve an energy performance rating in the top 25%  of facilities nationwide, earning them the prestigious Energy Star designation from the U.S. Environmental Protection Agency (EPA). 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 them meet their green healthcare initiative goals.

The 500 Series Hurst Boiler 700 HP system delivers on every front. Ron Piotrowski, Plant Operations for St. Elizabeth Hospital stated the “greatest benefit to the hospital is that the boilers run efficiently with very low excess air and our steam pressure doesn’t deviate from the 60 PSI set-point.” The hospital’s old boiler system used to cycle constantly, even in warm weather. “Now, with outside air temperatures nearing 100 F,” said Piotrowski, “our 700 HP Hurst Boilers don’t even cycle. The high turndown Riello burners on our Hurst boilers allow the system to run efficiently down to 10% of full firing rate.” Sturdivant added that the efficient turndown of the primary 700 HP Hurst boilers will negate the need to purchase and install a separate smaller summer boiler, saving the hospital even more money over the long run.

President Dan McCotter was pleased to have the opportunity to provide the company’s Hurst Boiler 500 Series ‘high efficiency Red Boiler Package,’ which offers the ‘smart energy’ benefits of the Riello high efficiency burner and integrated touch screen controls with real-time efficiency monitoring.
