The article provides information on the process of reducing capital cost of mechanical systems and increase operating efficiency through a higher temperature differential ( ?T) and return-water temperatures below 160�F. According to the author, designers can build smaller, more streamlined systems by increasing ?T and decreasing flow. He added that long-term fuel savings are even more significant, when low-temperature water is returned to a condensing and modulating boiler.
