How to determine the energy efficiency of your heater?

Heating your house during frigid winter days can be a costly endeavor. You must develop ways to regulate your heating needs to avoid paying huge bills that can interfere with your budget. A fundamental factor that surges energy bills in households is malfunctioning heaters that consume more energy than required.

One of the significant energy-consuming devices in a house is its furnace. Suppose you are interested in saving a substantial amount of money and minimizing your energy use. In that case, it is imperative to understand that you have a furnace that successfully transforms its fuel source into heating power with a small amount of waste.


The acronym AFUE stands for Annual Fuel Utilization Efficiency. It is one of the best ways to determine the energy efficiency of your heater. It tells how well your furnace converts fuel source, natural gas, electricity, and propane, into energy.


Although AFUE rating is an excellent determinant of your heater’s energy efficiency, it is not the final determinant. This is because you cannot maintain your heater’s performance throughout its entire life span. A top-rated heater can last up to twenty years. However, the quality keeps diminishing each year by five percent. Maintenance can improve the overall performance of a heater, but it cannot extend the heater’s longevity. Therefore, it is imperative to replace your heater after a certain period to enhance its efficiency. Luckily, numerous cost-effective heaters use minimal energy. If your current heater is consuming too much energy, consider replacing it with a more efficient one.


Although numerous factors may lead to changes in bills besides your furnace, drastic change in your energy bills can indicate an issue with your heaters. Begin by counterchecking your previous bills. If you realize a sudden and unexplained surge in energy bills, you could ascribe that to the degradation of your furnace.


Whether your home is properly maintained or not, even the high-rated AFUE will find problems due to poor insulation or cracks in windows and doors. There is a widespread problem, especially in older homes. Getting possible drafts on areas surrounding the windows, doors, and fireplaces is what is referred to as an airtight test. This can assist in identifying if the issue has less to do with your heater and more to do with how your home is constructed.
