You have already read plenty about how energy costs are rising. You know plenty well that heating your New Hope\u00a0home is a substantial expense, and that the cost of running a boiler is constantly on the rise.<\/p>\n
But as technology has gotten better, so have boilers<\/a> become more efficient at providing heat. It stands to reason that a more efficient boiler is one that costs less to run…but what does “efficient” really mean in the context of boilers? What makes a boiler “high efficiency”?<\/p>\n All boilers are rated according to a standardized system of rating efficiency, called the Annual Fuel Utilization Efficiency (AFUE). Essentially, this rating tells you how much heat energy is produced by your New Hope\u00a0boiler<\/a> compared to how much energy it draws. The higher a boiler’s AFUE rating, the more efficient it is.<\/p>\n For a boiler to be called high efficiency, it must carry an AFUE of at least 90%. For basis of comparison, older systems carry an AFUE of about 70%, while mid-efficiency systems run at about 82%.<\/p>\n In addition, a high efficiency system has a second heat exchanger for capturing and condensing flue gases, as well as a closed combustion system.<\/p>\n These three things — an AFUE of 90% or above, condensing flue gases and closed combustion – define a high efficiency boiler.<\/p>\n The initial investment in a high efficiency boiler can be costly, but the savings over time in your New Hope heating<\/a> bills make it well worth the expense.<\/p>\n\u00a0What Is a High Efficiency Boiler?<\/h3>\n
