High Turndown Condensing Boilers – Is Yours Condensing in Low Load Conditions?

Industry consensus is we need return water temperatures in the low 130’s to condense and improve efficiency by capturing the latent heat of flue gas inherent with this process.  This is the highest temperature under normal conditions in which condensing occurs, further lowering system return temperatures from this point greatly increases condensing and efficiency.  The lower you go, the more you benefit from this technology.  Read on ...
