Features, Advantages of Condensing Boilers: How new-breed boilers are simplify fog hydronic-heating-loop design

摘要

Much of what characterizes "traditional" hydronic-heating-loop design - greater-than-l40℉ return-water temperatures, conservative 20℉ ΔT, primary/ secondary piping, temperature control at terminal units, ducting and venting accommodations - has been strongly influenced by the operating limitations of gas-fired boiler equipment. This article will discuss how a new breed of boiler is challenging conventional practices and supporting new approaches to improve the cost and energy efficiency of hydronic heating loops.
