electrical to thermal radiant
Waste heat.
The answer is heat engine.
Electrical energy is converted into thermal and kinetic energy.
Chemical to thermal.
The stove itself is not but if it is a wood burning stove, when it is used, the conversion of wood into heat is the conversion of chemical into thermal energy
