ACSI recently installed a new boiler, a high efficiency burner, an economizer and related energy saving equipment as a way to help a local hospital save energy costs. A boiler is only as efficient as the burner it is mated to and ACSI installed one of the most efficient burners available. The old burner was 76 to 78 percent efficient, at most. With the new burner at 80 to 85 percent efficient, the commodity savings will be huge. To capture further savings, the client elected to install an economizer too. Since the facility couldn't shut down for work to be completed, the utilities remained operational while the older unit was safely disconnected and removed.
