When it comes to on-going value for your heating you want to consider an energy efficient furnace. The best systems not only burn less fuel, but less money in your wallet!

The "Efficiency" in AFUE

Furnaces, including gas furnaces, are classified by their “annualized fuel-utilization efficiency” (AFUE). AFUE ratings are shown in percentages. The higher the AFUE ratings are for a particular gas furnace, the more efficient the machine is. Older gas furnaces tend to have lower AFUE ratings than more modern models. In fact, furnaces with a standing pilot produced prior to 1992 often waste over a third of the fuel they use! On the other hand, furnaces produced after 1991 typically have a higher AFUE rating of 80%. Thus, the most direct and simplest way to own a more efficient gas furnace is to purchase a more efficient gas furnace. The best systems are condensing furnaces that have an annual efficiency of 90% or higher. These more modern gas furnaces have several benefits:

• Makes your furnace more efficient
• Wastes a maximum of only 10% of its fuel
• Reduces your current heating bill by about 25%.
• Lowers your spending on fuel.
• Uses a blower-fan motor that needs significantly less energy than older gas furnace models
• Allows the furnace to virtually pay for itself, within time. Those who live in colder climates use their gas furnaces more often, decreasing the time required for the machine to pay for itself.

Using a more efficient gas furnace will save you on your on-going energy costs - and as gas prices increase, your fuel savings increase as well. This can significantly offset the cost of upgrading the system.

The Quest for 97% AFUE

Actually achieving the efficiency ratings of the best systems takes more than just choosing the right model - it takes expert installation to fulfil the system's potential. A new system installed in the wrong location, that is incorrectly sized for the building, or installed with poorly designed ducts will not get the best out of that system - it's the expert touch of your Action Furnace installer that can get the most out of the furnace.

Other advantages of a more efficient, modern system include:

• High-efficiency furnaces collect combustion air directly from the house’s exterior. Conversely, lower-efficiency furnaces obtain combustion from the particular room where they are located meaning that after the furnace draws air, new (cold) air originates from various holes, cracks, etc. in the interior of the room.
• Newer furnaces also have burners with two stages or multiple speeds. The burners of older gas furnaces were either turned on or off. However, today’s more efficient furnaces function on cool days at lower settings, and for longer times. This results in cleaner air, and a better balanced distribution of air in a house’s rooms. These newer furnaces only have to burn at their full capacity for roughly 10% of the time - improving the working life of the system. An added bonus of of these multi-stage or multi-speed systems is the ability minimizing the amount of noise produced, because both the burner and the blower-fan can operate at lower speeds.
