How It Works

Principle of Operation

Radiant heating works on the principle of infrared radiation, a natural and efficient method to distribute heat. Unlike traditional heaters that warm the air, this system directly heats objects, surfaces, and people, ensuring even and comfortable warmth.

  1. A principle based on radiation physics

    php Copier le code
    • Radiant heaters emit infrared waves, similar to those of the sun.
    • These waves pass through the air without heating it and transfer their thermal energy when they come into contact with a solid surface, such as a floor, wall, or the human body.
  2. Immediate advantages:

    • Heat is felt quickly.
    • Even distribution without air movement, ideal for avoiding dust and cold drafts.
  3. Adaptable technology:

    • Indoor use: Heats rooms such as living rooms or offices.
    • Outdoor use: Maintains a pleasant temperature on terraces, patios, or event spaces.

Differences Between Radiant, Convection, and Conduction Heating

Radiant Heating:

  • Transfers heat through infrared radiation.
  • Ideal for open or partially exposed spaces where the heat needs to be felt directly.
  • Provides immediate comfort and uses less energy by avoiding heat loss through circulating warm air.

Convection Heating:

  • Works by heating the air, which then circulates through the room.
  • Can be less efficient in poorly insulated or wind-exposed environments, as the warm air can easily escape.
  • Creates temperature variations, which are often less comfortable.

Conduction Heating:

  • Requires direct contact with the heated surface, like underfloor heating.
  • Typically used in floor heating systems or specific radiators.
  • Provides localized heat but may be slow to warm large areas.

Efficiency High Medium Localized

History and Evolution of Radiant Technologies

From Ancient Origins to Modern Day

  • Antiquity: The Romans used a radiant heating system in their public baths, where conduits under the floor distributed heat.
  • 19th Century: The first modern applications of radiant heating appeared with open fireplaces and rudimentary hot plates.
  • 20th Century: The advent of electricity enabled the development of infrared panels for domestic and industrial use.

Modern Innovations

  • Electric Radiant Heaters: More compact and energy-efficient, ideal for residential spaces.
  • Gas Heaters: Powerful and effective for outdoor spaces like terraces.
  • Solar Technologies: Combining sustainability and performance by harnessing renewable energy.

Current Trends and Future

  • Smart Technologies: Modern radiant heaters integrate smart sensors to automatically adjust the temperature.
  • Eco-Design: Use of sustainable and recyclable materials to reduce the ecological footprint.
  • Design Integration: Elegant solutions that harmonize perfectly with modern interior and exterior design styles.

The operation of radiant heating combines simplicity, efficiency, and innovation. By using a natural and effective heat distribution method, it adapts to a wide variety of spaces while offering significant advantages over traditional technologies.
