In the heating process sequence, what is the second step?

• A. Fuel burning
• B. Boiler Cycling
• C. Water heating
• D. Distribution

Answer: (D)

The thing being tested is how heat moves from its source to where it actually warms a space. After fuel is burned to create heat, the next action that makes that heat usable is moving it through the system to the living areas—the distribution network. The boiler may heat the water, but the critical next step is distributing that heated water or steam via pipes, pumps, and radiators so rooms can gain warmth. Water heating inside the boiler is part of generating heat, and boiler cycling is about the boiler turning on or off to maintain temperature. But the step that delivers the heat to the building, as a distinct action, is distribution.
