Heating methods refer to the various techniques used to increase the temperature of a space or substance. Common methods include electric heating, where electric currents generate heat, and gas heating, which uses natural gas or propane. Other methods include radiant heating, where heat is emitted from a surface, and convection heating, which circulates warm air throughout a room. In addition to these, wood burning and solar heating are popular alternatives. Wood burning involves using a fireplace or stove to burn wood for warmth, while solar heating harnesses energy from the sun to heat water or air. Each method has its own advantages and applications.
