Agree with everything you say, except the power output/input ratio.
No way you can get 20X the energy
out of a heat pump that goes into it.

The ratios I gave were BTUs/hour over watts. I didn't bother with the
conversion factor to make it a real output/input ratio (for example
watts out over watts in) because the only point was to compare the two
units.

Thanks for reading carefully!
