Lesson Overview
This lesson covers the principles of thermal radiation and thermal expansion in plumbing and heating systems. You will learn how radiant heat behaves, how materials expand when heated, and how to accommodate pipe movement on site.
Learning Objectives
Explain the principles of thermal radiation, including heat absorption, reflection, and emission.
Calculate the linear expansion of copper, plastic, and steel pipework using the coefficient of linear expansion.
Identify practical installation methods used to accommodate thermal movement and prevent noise or joint failure.
