Thermodynamics won’t allow anything to have an efficiency of 100% because some energy will be converted to heat. What about electric irons and pretty much any other heating equipment that has a working principle revolving around losing energy to heat

This is incorrect.
Thermodynamics won’t allow anything to have an efficiency of 100% because some energy will be **lost when converted from one form to another**. It’s not always lost as heat
And iron converts electrical energy to heat energy. That conversion is not 100% efficient, some energy is lost.
