When you are choosing a heating system for your factory, manufacturing plant or even office space it is important to understand the underlying basis of a central heating system. There are two notable facts of a heating system that makes each one different to the other. They are the method by which the heat is transferred and the classification of the heat transfer. Read below to learn more on the different kinds of heating systems.

Heat Transfer Method
Generally, the transfer of heat is done in three methods. They are conduction, convection and radiation. Most of the industrial heaters use either one or more of these fundamental heating methods to transfer the heat energy. Conduction refers to the transfer of thermal energy through a solid object. The basic idea is that when the thermal energy is passed on to a solid object the molecule in object starts to vibrate giving out heat energy and passing out this heat energy to the adjoining molecules. Convection on the other hand refers to heat being transferred by the thermal energy through a fluid or medium. A convection current is thus created that can be either forced or free flowing. Radiation is a completely different method. It is an indirect heating method. Where thermal radiation is transferred through electromagnetic waves.

Classification: Application
Efficient Industrial heaters can be classified according to their application. Some such heaters are namely circulation heaters, room heaters, duct heaters and space heaters. Circulation heaters are used to heat moving, flowing or circulating fluid streams. Circulation heater can use either liquid or gas for the purpose. One of the most common application of the circulation heater would be a livestock tank. Duct heaters use either convection or thermal radiation for their heating. They can be used to heat moving air. This method of heating is commonly used in baking systems.

Classification: Medium
An Electric heater can also be classified according to its medium of heat transfer. Heat can be transferred by either air or water. So there are air heaters and water heaters. An air heater includes all kinds of heating systems that use air to heat. The air can either be forced or radiant or space heaters. Water heaters, as the name suggests uses water for its heating purposes. Water heaters use gas, oil or electric fired devices to heat the water which can then be used for either commercial or residential purposes.

Classification: Physical Properties
Flexible heaters and explosion proof heaters are the kinds of industrial heating systems that can be classified according to their physical properties. Explosion proof heaters are designed with exteriors that are specifically designed to withstand any kind of explosion. This includes housings that can uphold sparking or erupting in flames under every circumstances. These kinds of heaters are especially necessary in highly inflammable natures. Flexible heaters on the other hand are heaters that can be moulded into any shape of the heated object.
