A52 -- Snow Melting and Freeze Protection (SI)

This chapter covers three types of snow-melting and freeze protection systems: (1) hot fluid circulated in slab-embedded pipes (hydronic); (2) embedded electric heater cables or wire; and (3) overhead high-intensity infrared radiant heating. Detailed information about slab heating can be found in Chapter 6 of the 2020 ASHRAE Handbook—HVAC Systems and Equipment. More information about infrared heating can be found in Chapter 16 of the same volume.
