You’ve probably seen the yellow sticker on your boiler, but chances are you haven’t paid it much mind in the past.
The truth is, that sticker is kind of important, because it includes your boiler’s AFUE (Annual Fuel Utilization Efficiency) rating – a measure of efficiency for your boiler. In a boiler with an 85 percent AFUE rating, 85 percent of the fuel it consumes is converted to heat in your living space; the rest is lost along the way – more on that in a minute.
Although AFUE is a good starting point when it comes to evaluating energy efficiency, it is not the only factor to consider. In fact, a study showed that you could spend as much as $800 more per year for fuel with one boiler compared to another with a nearly identical AFUE rating.
How can this happen?
Simple: AFUE only measures energy lost by the boiler itself – usually to the chimney. It does not take into account other factors that can affect a boiler’s efficiency, including:
To get a real world measure of boiler efficiency, you need to consider all these issues and more.
The good news is someone has already done that work for you. Downey Energy offers boilers from Energy Kinetics whose unique design minimizes or eliminates chimney, jacket, idle, and draft regulator loss.
