Understanding Heating System Energy Efficiency
With energy costs rising more and more people are looking at how they can increase their home heating systems’ energy efficiency. TLC’s HVAC technicians stay current in the latest heating and cooling technology advancements to ensure we offer customers ways to improve their energy efficiency for their heaters while staying comfortable.
Home heating is the largest energy expense in the average U.S. home, it accounts for about 45% of energy costs.
Natural gas is the most common fuel used to heat homes in the U.S., its used in about 57% of homes.
Understanding Heating Energy Efficiency Ratings
The efficiency of furnaces and boilers is measured by Annual Fuel Utilization (AFUE). AFUE= How efficient the heater is at converting the energy in its fuel to heat divided by the annual fuel energy consumed by the heater. You will see it described as follows:
Old, low-efficiency heating systems.
These systems are often found in older homes and were installed several years ago.
It is probably time to consider replacing a furnace this old.
80 – 83%
Mid-efficiency heating systems.
80% AFUE is currently the lowest energy rating you can currently get in a Furnace.
There are many single and two stage furnaces available in this range.
90 – 98.5%
High-efficiency heating systems.
These types of heating systems are going to offer the most energy savings while maximizing comfort levels.
These types of systems are going to be variable speed furnaces and condensing boilers.
Tips to lower your heating costs
Here are some easy tips to control your heating costs this winter and still keep you comfortable.
High-Efficiency Variable Speed Furnaces
A traditional single stage furnace operates in either “on” or “off” mode. A multi-stage furnace has a high and low speed. However, a Variable Speed motor allows the blower to adjust the speed of the motor incrementally based on the heating needs in your home. This type of motor increases fuel and electrical efficiency, provides consistent heat, reduced noise, and cleaner air. Talk to your TLC technician about energy efficiency furnace options when it is time to replace your existing furnace.
