Heat transfer

Heat is transferred in three ways:

  1. Conduction

  2. Convection

  3. Radiation

1. Conduction is the transfer of heat between objects that are in direct contact with each other. As with all three forms of heat transfer, heat is always transferred from a warmer to a colder object. Examples of heating systems that use conduction are electric blankets and electrically heated clothes and shoes.

2. Convection is the way that heat is transferred through gases and liquids, which expand and rise when warmed and contract and fall as they cool down, creating a convection current. Examples of this indirect type of heating are hot water radiators and fan heaters.

3. Radiation is the transfer of heat that occurs when electromagnetic waves from a warm object travel through space and come into contact with a cooler object. Examples are simple fireplaces, woodstoves and marble radiators by Elith.

In conclusion, we’ve seen that there are a number of ways to heat a space. This fact, along with aesthetics, functionality and cost, should be taken into consideration when choosing our heating system.

Efficient heating and natural heat transfer: Compared to other heating systems, infrared heating systems are more efficient and much better for our health and our surroundings. Several different types of infrared heating system have been developed. They can be installed almost anywhere—on floors, walls and even on ceilings. In terms of cost and efficiency, infrared heating systems are a better alternative to other conventional heating systems.

The family of infrared heating systems: Infrared heating systems are based on the general capacity of every object in Nature to emit, absorb and reflect infrared radiation. The amount of infrared heat transferred by an object is in direct relation to its surface temperature and its emissivity coefficient. Elith infrared marble radiators transfer heat by radiation—invisible to the eye but felt by the skin as warmth. Infrared radiation creates a comforting thermal sensation in the heated space because the temperature of the environment is in harmony with the temperature of the human body.

Advantages of  infrared heating systems: Infrared radiation is invisible, low-energy electromagnetic wave radiation that is sensed by human beings as wamth. Extensive research has shown that weak infrared heat radiation has a positive effect on human health and wellbeing and has no harmful effects on any living organism or the environment. A typical example of weak radiation is the harmless, everyday exchange of heat between human beings and their environment. Artificial infrared radiation emitted from heaters warms our domestic and working spaces. Infrared heaters are also used in medicine to treat certain diseases and relieve pain. Elith infrared  marble radiators are made from100% natural stone. They are safe to use, and have all the required safety certification.
