Case Study: Pumping up Solar Power Savings
Posted on August 9, 2011 by — No Comments
Circulator pumps were the highlight of this month’s Reeves Journal
magazine that featured a case study from global pump and pump systems manufacturer Grundfos. Over the last five years, circulators used for hydronic and radiant heating systems have become more energy-efficient thanks to ECM (Electronically Commutated Motor) technology. The intelligent speed control these circulators provide is drastically reducing energy use without sacrificing performance.
To understand why this technology is so appealing, put yourself in the shoes of plumbing contractor Mike Wolking, who was asked to design a plumbing and hydronic heating system for a custom solar home in south-central Colorado.
In addition to specifying a system that could provide space heating and domestic hot water for the 2,300-square-foot, two-story ranch, Wolking’s design had to consume roughly 40 percent less energy. Read more here.
