A central furnace or boiler's efficiency is measured by annual fuel utilization efficiency (AFUE). The Federal Trade Commission requires new furnaces or boilers to display their AFUE so consumers can compare heating efficiencies of various models. AFUE is a measure of how efficient the appliance is in converting the energy in its fuel to heat over the course of a typical year.
Specifically, AFUE is the ratio of annual heat output of the furnace or boiler compared to the total annual fossil fuel energy consumed by a furnace or boiler.
Furance Modification is highly preferred in the following Major Areas:
Advantages of Furance Modification:
Adjust the controls on the boiler or furnace to provide optimum water and air temperature settings for both efficiency and comfort.
