Heat pumps move heat from outside to inside, and they use less energy than the amount that is brought into the insulated area, resulting in efficiency numbers over 100%. (less energy used than the amount brought inside was used to bring the inside energy levels up)
Is a heating element actually 100% efficient, though?
Some of the energy is converted to light.
