Could it possibly mean that some heat is being produced by that compressor ? Now I don't have time to go back and make a presentation showing mathematically what is happening nor do I think I can remember the equations, but those are the observations that I observed!

Reverse cycle units tend to consume more power in heat mode. Yes, the compressor adds to the heat produced in heat mode. Likewise, in cool mode the compressor losses reduce the amount of “cold” produced.
