Wondering what AFUE rating has to do with buying a new heater? You’re not the only one! Many people who haven’t bought a new heating system before have no idea what this rating means or how to use it. Although frustrating at times, ratings and standards play an important role in protecting consumers and the environment. In the absence of objective ratings, it can be hard for consumers to make an informed purchase.
Heating systems are a big investment, and homeowners deserve to know what they’re getting for their money. An AFUE rating describes how energy efficient a furnace or boiler is, which has many financial and non-financial implications. If you need a new heating system but aren’t sure where to start, don’t stress — the HVAC professionals at Strittmatter Plumbing, Heating and AC can help you decide.

What Is an AFUE Rating?
Annual fuel utilization efficiency (AFUE) is a rating that measures a furnace or boiler’s efficiency , or how much usable heat is generated by a particular heating system. AFUE rating is represented by a percentage, and the higher the percentage, the more efficient the system. For example, if a furnace or boiler has an AFUE rating of 95%, that means that 95% of the fuel used by that system will go to heating the home. The other five percent is wasted in the heating process. The AFUE rating system was designed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). The U.S. Department of Energy (DOE) requires all furnaces to have a minimum AFUE rating of 78%, though there are proposals to increase the minimum AFUE rating to 92%.Why Is AFUE Important?
Understanding how much fuel certain appliances use is a critical step in choosing more energy-efficient systems. AFUE is important for several reasons, including its ability to predict utility costs and measure energy consumption.Utility Costs
When homeowners buy a new furnace or boiler, they deserve to know how efficient the system will be. Without a rating system, consumers might accidentally buy a system that’s extremely inefficient and increases their utility bills. Although heating systems with high AFUE ratings may require a larger upfront investment than systems with low AFUE ratings, they can save homeowners a lot of money on utility bills.Energy Consumption
Many homeowners are concerned about their carbon footprint, and AFUE ratings help them pick heating systems that waste less energy. The government also has a stake in ensuring manufacturers consider the energy consumption of their product, as the vast majority of furnaces are powered by non-renewable energy.Benefits of High-Efficiency Heating Systems
Although saving money on utility bills and conserving energy are arguably the biggest benefits of a high-efficiency heating system, those aren’t the only benefits. Here are some additional perks to buying a highly efficient heating system:- Longer-lasting furnace. Highly efficient systems generally have on-and-off cycling programs that help them both conserve energy and limit wear and tear.
- Less maintenance. New, high-efficiency systems won’t require the same amount of repairs and maintenance that a struggling, inefficient system will.
- Better heat distribution. Highly efficient heating systems that use newer HVAC technology will heat your rooms more evenly than an antiquated system.
- Increased home value. Thinking of selling your home in the next couple years? A high-efficiency heating system will add value to your home when you’re ready to sell, saving you money on utilities in the meantime.
