This photo shows where I am at now.

The 2 dehumidifier HX's are plumbed together in series to make a larger evaporator as was suggested in other threads.

I removed the original squirrel cage fan which drew 80/85 watts and replaced it with a 200mm computer case fan with 18v power brick that draws 14 watts and seems to push as much or more air.

Added permanent gauges, service valves, and two flare connections.

Charged it with BBQ gas and have run a few tests to determine that the fan I am using is really better than the squirrel cage fan.

One of the flare connections may be leaking so I need to attend to that next.

Then I will be doing some bench tests to collect data and calculate efficiencies. I hope that I can determine efficiency at various water temps and refrigerant charges.
