Engine
A device that converts electric energy into thermal energy. A device that regulates the temperature of a system. A device that uses electric energy to transfer thermal energy from a cooler location to a warmer location. A machine that converts thermal energy into mechanical energy.

An engine.
A toaster is one of many such devices.
The device that converts electrical energy to thermal energy is an electric heater. It works by passing an electric current through a resistive element, which generates heat due to the resistance of the material. This heat is then transferred to the surrounding environment, raising the temperature of the space.
It is a thermocouple that converts thermal energy into electrical energy through what is called the thermoelectric effect.
Almost every mechanical device converts some of its mechanical energy to thermal energy. Some examples I can think of at the moment are: -- drill bit -- saw blade -- file
Burning a material converts chemical energy into thermal energy.
A device that converts thermal energy into work is called a heat engine. Heat engines take thermal energy from a heat source, such as combustion or nuclear reactions, and convert it into mechanical work through processes like expansion of gases or steam. Examples include steam engines and internal combustion engines.

A stove is a device that converts chemical energy (from fuel like gas or wood) into thermal energy through combustion. The thermal energy generated heats up the stove elements or burners, which in turn transfer the heat to cookware or food placed on them.
