Chapter 5.1.3 - Radiant Panel Systems Evaluation

By Richard D. Watson and Kirby S. Chapman
From Radiant Heating and Cooling Handbook

There are many advantages unique to radiant panel systems. The authors have
included those recognized in ASHRAE Handbook Fundamentals, research, and manufacturers’
literature. The importance of each feature will vary with the application
and geographic location. However, a full understanding of the impact of radiant panel
features on design comparison is essential to a robust comprehensive evaluation.

Radiant panel evaluation features include the following:

  • Better comfort levels because radiant loads are satisfied directly and air motion is
    at normal ventilation levels.
  • Energy savings due to reduced air infiltration and exfiltration, lower or nonexistent
    heat transmission losses compared with ducted systems, and lower heat loss
    due to dry-bulb air temperatures that are no higher than the level required for
    occupant thermal comfort.
  • Low or minimal maintenance is required for radiant panels.
  • Reduced air filtration as makeup air is required only for ventilation and not for
    deliveries of heat as forced-air systems require.
  • One hundred percent usable floor space and simplified wall, floor, and structural
    systems because...
