About hardware

I know i am asking a question in the wrong forum but so far this forum has answered almost all of my problems.

if a heater says 1500w with 70% efficiency, does that mean the actual Watt it is consuming is 1500/.7 which is 2142w? (which will tax on my utility bill)?

And what is the efficiency (doin't need to be exact) for a Ceramic Electric Heater?
What it says is that 30% of the energy it consumes is wasted, pretty much. Unfortunately, I don't know the average efficiency for a certain type of heater, sorry. Try Google? :(

As an aside, if an electric heater is only 70% efficient, where does the other 30% go, given that usually inefficiency in energy transformation in appliances is dumped as heat?

I'd expect heaters to be really, really efficient. Sound doesn't take much energy. What else is there?
The numbers in the first part could just be made up from a problem or something.
