Question 4: Which efficiency rating measures the annual fuel utilization efficiency of a furnace?
A) SEER
B) HSPF
C) AFUE
D) COP
Correct Answer: C
Explanation: AFUE (Annual Fuel Utilization Efficiency) is used to rate the energy efficiency of furnaces
and boilers.
Question 5: What is the most common method of heat transfer used in radiant floor heating systems?
A) Conduction
B) Convection
