What is a common characteristic of radiant heating systems?

Radiant heating systems are designed to deliver heat through infrared radiation, which is a fundamental characteristic that sets them apart from other heating methods. These systems use radiant panels installed in floors, walls, or ceilings, or use radiant heaters that emit infrared waves. The heat produced warms objects and surfaces in the room directly rather than heating the air first. This method results in a more comfortable and efficient heating experience since the warm surfaces then gradually transfer heat to the air.

In contrast to this, systems that rely on moving air or deliver heat through direct air heating do not employ infrared radiation as their primary heating method. Extensive ductwork is typically associated with forced air systems and is not a requirement for radiant heating applications, which can operate effectively without duct systems. Radiant heating enhances comfort and reduces energy consumption by eliminating the temperature stratification often found in forced air systems.
