Understanding Boiler Efficiency Ratings: What Do They Mean?
How Efficient Is Your Boiler? You Might Be Losing Money Without Knowing It
Did you know your boiler could be wasting up to 20% of your heating costs?
Understanding your AFUE (Annual Fuel Utilization Efficiency) rating is key to lowering energy bills and improving home comfort.
✔ An 80% AFUE boiler wastes about 20 cents per dollar
✔ A 95% AFUE system wastes only 5 cents
✔ Modern high-efficiency boilers can reach 90–98% efficiency

That difference can mean hundreds in yearly savings 💰
But efficiency isn’t just about the system—it’s also affected by:
• Heat loss through exhaust and pipes
• Aging components and poor maintenance
• Installation quality
💡 Upgrading to a high-efficiency (condensing) boiler or scheduling regular maintenance can significantly reduce energy waste and extend your system’s lifespan.
