The AFUE annual efficiency ratio measures energy efficiency of your heating system

I’ve been shivering every night while I try to sleep.

I don’t know about others, but being cold at night causes me to get insomnia. Even if I take melatonin or benadryl, the shivering keeps me awake for hours. I figured that a warm blanket and fluffy pajamas would be enough to keep me warm during the twilight hours, but they’re not. If we keep getting blizzards every week like we have for the past month, I’m going to have to make some kind of serious change in my house. It’s a matter of having on demand heat that doesn’t cost so much money that I can’t afford to run it. In the past I’ve had central furnaces that drove up my electricity bill so high that I struggled to rationalize using them. For the longest time I didn’t know of any other kind of residential heat than electric furnaces and wood stoves. I was amazed when I learned about all of these other kinds of heating systems for houses. My electric furnaces of the past were simply one form of fan-forced heating, of which there are other options like gas powered and oil powered furnaces. Otherwise I could get a water heated system like a steam boiler, which itself is either heated with electricity or fuel of some sort. Regardless of what kind of heating system you choose, I discovered there’s a rating system called the AFUE. It stands for annual fuel utilization efficiency and it measures the efficiency of a heater based on how much heat it produces from the fuel it consumes in the process. This allows you to compare the efficiency of an electric furnace to a boiler system without having to fumble around with ratios and other equations.
