The thermometer is the most obvious example of heat directly causing work being done (it expands or moves the Mercury in the thermometer). The steam engine was invented before the thermometer. So,that one too. A gun,rifle or a machine gun also uses the stored energy in the gun powder to propel the bullets. The machine gun works on the principle of heated gas expanding thus propelling the bullets. All rockets form simple firecracker type to the Saturn 5 are propelled due to the Chemical reactions that give off concentrated heat and thrust. Blow dryers use electricity to produce heat. Coal powered trains and all engine powered vehicles.

Called? Perhaps heat pump? Thermodynamics governs the relationships between heat energy and work. Any machine that uses heat to produce work is governed by thermodynamics. Work is produced by the movment of heat from one region to another. The opposite can also be used in the form of refrigeration systems that use mechanical work to move heat from one place to another.
Pressure p, volume V, mass nR, and temperature T are the parameters governed by
pV=nRT
and work W is given by
dW=pdV

Busen burners use a gas flame to heat things. With a hot plate, you put the object on the metal plate and electricity heats the plate, in turn heating the object. Sounds like you're talking about a hot plate.
