Nice rig. It's looking to me that you have proof of concept. Hopefully the experiment convinced you to continue refining the beast.

The calculations you have done do far don't really lead to anything useful or accurate yet. Too much uncertainty and too short on run time. To get very accurate measurements and calculations out of these things they have to be run for a lot longer than a few minutes. I'm sure your worm coil heat exchanger is doing its job, and so is the outdoor unit, but that's about it. Run the thing for a week with a kilowatt hour meter attached and let us know how much better it works than an electric space heater.
