one very short list: 1) the sun (basically a fusion reactor for this consideration), 2) burning things (combining almost anything with oxygen and an ignition source [like a match] like wood, oil products, magnesium, and a long list of others), 3) most fissionable material, 4) electric current through a resistive wire, 5) any exothermic chemical reaction (a very long list, including biomass, food digestion, muscle movement), 6) physical work like friction,

name the sources of history
There are heat sources in a lot of different things. A heat source is something that can heat something else up. There are heat sources in microwaves, ovens, and cars.
Bunsen burner
There are two main sources of heat for cooking, gas and electric.
The six sources of heat are: radiation, conduction, convection, friction, nuclear reactions, and chemical reactions. Heat can be generated through these different processes either naturally or artificially.
Spark, heat, & lightning.
There are mainly four sources of heat: Conduction - heat transfer through direct contact. Convection - heat transfer through fluid motion. Radiation - heat transfer through electromagnetic waves. Combustion - heat produced by burning fuel.
Two categories of heat sources are natural heat sources and artificial heat sources. Natural heat sources include the sun, geothermal energy, and volcanic activity. Artificial heat sources include electric heaters, gas heaters, and oil heaters.
solar and wind
Main sources of internal heat are Magmatism and Radioactivity.
All heat sources. Plus extreme cold sources cause burns.
