You have your heat exchangers mixed up. The evaporator is the cold one in the suction side, the condenser is the hot one on the discharge side, of the refrigerant loop.

What you have been doing with your DX water heater setup seems ideal for your purpose: big coil indoors with low airflow to grab lots of water vapor, condenser heating not indoor air, compressor located outdoors. With these smaller setups, the compressor is usually the weak link in the heat transfer equation. Due to the limited (nearly constant) displacement, it can only move so much gas.

With your half ton compressor, you can move around 6.3 megajoules of heat per hour. This translates to about 3 pints of condensed water per hour in a perfect process. i would shoot for a liter per hour tops. This is what you can hope for.
