We purchased the Greffen M2G Dec 2009 for our 199hp Weir-McLain boiler as part of our mandated (EPACT/EISA) ECM. We saw an immediate 18% reduction in fuel use. (nat gas or #2 fuel oil) and an ROI of less than 12 months. Installed in less than 4hrs and walked away, and our building occupants have not noticed any difference in comfort. The easiest savings we've done for less than $8000.00
