High Efficiency Heating Systems

High Efficiency Heating Systems

Heating is the largest energy expense in most homes, and reducing your energy use for heating provides an effective way to reduce your home’s contribution to the global environment. Heating systems in the United States spew over a billion tons of CO2 into the atmosphere each year and about 12% of the nation’s sulfur dioxide and nitrogen oxides. Upgrading your old, less efficient home heating system with a new, highly efficient system can not only cut your energy bills, but also reduce your pollution output by half, and save 1–2 tons of CO2 emissions each year.

Understanding AFUE

The Annual Fuel Utilization Efficiency (AFUE) is a measure of the efficiency of a furnace or boiler heating system. The higher the AFUE, the more efficient the boiler or furnace is. The Federal Trade Commission requires the AFUE be indicated in the newer models of furnaces or boilers so that consumers can compare the efficiency ratings between different models.

The AFUE represents the ratio of the annual heat output of the furnace or boiler, to the annual fuel consumption. A boiler with an AFUE of 90% means that the boiler converts 90% of the energy from fuel into heat, and loses only 10% of the energy to the chimney and the atmosphere.

Advantages of High-Efficiency Furnaces and Boilers

  • AFUE of 90% to 98.5%
  • Sealed combustion that brings outside air directly into the burner and the gases outdoors
  • Gases go to a second heat exchanger for maximum efficiency

Disadvantages of Low-Efficiency furnaces and Boilers

  • AFUE of only 56% to 70%
  • Creates backdrafting of gases indoors which is hazardous to your health
  • Heavy heat exchanger
