To know what heating is, therefore, you must first understand what the action of heating consists of. This verb refers to the transmission of heat to an object or body, causing an increase in its temperature (that is, the physical magnitude that, precisely, reveals the level of heat).
Returning to the idea of heating, you can point to the method used to provide heat or to increase the temperature . The usual thing is that it is used to name the set of equipment and devices whose function is to heat an environment .

Radiator for heating a room.
Types of stove
Currently different types of stove are marketed. The most popular are gas stoves that have a burner where combustion takes place and that have ventilation.
The electric heaters , in turn, produce heat with electrical current by the so - called Joule effect (involving the transformation of a percentage of the kinetic energy of the electrons into heat). There are also stoves that have a radiator , a metal piece that shelters the circulation of a hot fluid to transmit heat to the environment.
When there is a single source that is responsible for increasing the temperature of an entire building, it is called central heating or central heating . In this case, there is usually a boiler to heat the water that feeds, through pipes, multiple radiators.
Heating, key in air conditioning
Air conditioning consists of providing an environment with the necessary conditions of temperature, humidity , etc., to ensure the comfort of the people who are on the site. Heating, in this framework, is very important in the winter season and in colder regions.
