Describe how radiant heating relates to human comfort. 3. How does high-mass radiant heating compare to low- mass radiant heating? 4. What are three different heat sources for radiant systems, and how do they compare? 5. Describe how different types of piping materials are used in radiant heating systems. 6. What are some of the differences between PEX tubing and PE-RT tubing? 7. List the installation procedures for installing slab-on- grade and thin-slab flooring systems. 8. Describe where above-floor prefabricated panels would be used instead of a thin-slab flooring system. 9. How does a below-floor suspended tubing system compare to prefabricated above-floor panels? 10. What are some advantages of using wall or ceiling radiant panels? 11. List the parameters that need to be determined when designing a radiant heating system. 12. What are the two factors used to select a circulating pump for a radiant heating system? 13. How do radiant heating controls compare to the controls used with a conventional heating system? 14. List the components that make up a snow and ice melt system. 15. How does the installation of a snow and ice melt system compare to other types of radiant heating systems? Critical Thinking 1. Describe how radiant heating systems might be used for various commercial applications. 2. What would be the process for retrofitting a radiant system into a residential or commercial building that has a conventional heating system?
