If you haven't already, please try to read through Jake's (Memphis91) build. His HPWH turned out really well, especially considering he knew very little about refrigeration circuits when he began. The optimization of the phase change loop begins about here:

Since you are building an air-source unit, your struggle will be easier. Air coils are much more forgiving until ambient temps drop close to freezing. They are very predictable.

There are so many contributions from members and sources of information to ponder concentrated in that thread. Jake also had a way of guiding the conversation, asking the perfect questions, and providing nearly instant feedback and data to just plain get the thing done fast. Thing about it, he is still following up with usage and performance data a year later. I hope yours turns out as well as his did.
