No matter where you live, getting through the winter months without a furnace probably isn’t a pleasant prospect. Not all furnaces are created equal, however. There are a number of vastly different options available, each capable of meeting your heating needs in different ways. So, how do you choose the best one? Let’s take a look at what you need to know to pick the most efficient furnace.
AFUE stands for Annual Fuel Utilization Efficiency. This number measures how efficient a furnace is at converting fuel into heat over an average year. The higher the number, the more efficient the unit is. For example, if a furnace has an AFUE of 60%, it means that 60% of the fuel it burns is converted into heat while 40% is lost to other factors. That isn’t a very efficient furnace. Furnaces with a lower AFUE will require more fuel to reach target temperatures, which will cost you more money. The current minimum requirements are around 80% for most types of furnaces, but you should still examine each unit to compare AFUE numbers.
The most efficient furnaces will have the ENERGY STAR label on them to highlight their efficiency. These are probably the best choice in colder climates. Their extremely high AFUE rating (90%+) makes them the least expensive if they are going to be used quite often.
Retrofits and Replacements
There are ways to retrofit your older furnace to be more efficient. Oil burning furnaces can be converted to use gas, for example. Depending on how old your furnace is, however, it would likely be far more cost effective to simply replace it. Some older furnaces are extremely inefficient, and replacing them could double the effectiveness of your heating system as a whole. Ultimately, you will have to weigh your options and go with what fits your home situation the best.
