Since power is defined as energy/time, if you solve for energy, you get:
energy = power x time
If the time is in seconds and the power in watts, the energy is in joules.
It depends upon the wattage of the heater.
straightening iron, heater, pot on stove
we use thermal energy while heating our food on gas stove or microwave,or heater ,etc
Example is ,an electrical heater connected to a main switch and the heater is placed in a bucket filled with water.
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.

It converts electric energy to thermal energy

Because all the electrical energy supplied to the heater is emitted as heat. There is no other way for the energy to escape.

An electric heater ( the only known 100% efficient device ).
A heater is a machine that converts electrical chemical energy into thermal energy. Energy can not be created nor destroyed, only tranferred from one form into another. this is why in most heaters some of the chemical energy used is also transferred into some waste energies, eg: Light energy
