If efficiency for electric devices is defined as how well it converts electric power into the desired effect, the rest usually being heat, aren’t electric heaters 100% efficient? If i had a 99% efficient heater, what undesired form of energy would the 1% go to? I see a lot of electric heaters being marketed as “way more efficient than others”.

i could heat a home with an arc welder but the costs would be astronomical. on the other hand i could buy an oil-filled heater and use a small amount of electricity to heat the oil and it would continue providing heat even when the electricity has been turned off.
heating objects, not air, is generally the most efficient way to go.
