Radiant Heat

Definition

Radiant heat is heat transmitted by radiation, without needing a medium to carry it.

Purpose

The purpose of radiant heat is to directly warm objects and people in its path, rather than heating the air, providing efficient and uniform heating.

Examples of Use

• Radiant floor heating systems use warm water pipes or electric heating elements embedded in the floor to provide comfort.
• Radiant panels installed in walls or ceilings can heat a room by emitting infrared radiation.
• Outdoor patio heaters use radiant heat to warm people in outdoor settings.

Related Terms

• Convection: Heat transfer through the movement of fluids or gases.
• Conduction: Heat transfer through direct contact between materials.
• Infrared Radiation: A type of electromagnetic radiation responsible for heat transfer in radiant heating systems.

Notes

Radiant heating systems are often more energy-efficient than conventional heating methods because they directly heat objects and people rather than the air.
