Each of the following is a primary consideration in estimating annual operating costs for a water heater, except:
  1. Inlet pipe dimension
  2. Heater size
  3. Fuel type (e.g., gas or electric) and cost
  4. Energy factor
Explanation
Answer: A - The pipe dimension has little to no bearing on annual operating costs. Heater size, the type and cost of fuel it uses, and the water heater’s energy factor all have substantial effects on operating costs. Consumers should also consider the purchase cost and installation and maintenance costs when calculating total cost of ownership.
