Harmonized Plumbing Level 2 SLE Prep – Block B Heating and Cooling (PDF)

Block B: Heating and Cooling Systems

Stop guessing on hydronics questions.

Heating and cooling is where a lot of Level 2 apprentices lose marks. There are formulas for flow, head, and expansion, pressure readings that change depending on where the pump sits, and troubleshooting questions written to catch you out. This block breaks it all down in plain language, written by a working BC plumber and plumbing instructor, then tests you the way the exam will.

What's inside

- 4 lessons: heat transfer and hydronic basics, boilers and heat sources, piping systems and components, and controls, radiant heating and cooling. Each one has worked examples and quick-check questions.

- Review quiz: 40 exam-style multiple-choice questions, written to the same standards as trade exam items.

- Full answer key: every question comes with the correct answer, the chapter it comes from, and a one-line explanation of why.

Who it's for: Level 2 plumbing apprentices getting ready for their block exam, or anyone who wants a solid review of hydronic heating before heading back to school.

Study the lesson, take the quiz, and check the key. Then do it again until it sticks.
