Jack I would like to know why you believe a holding plate is more efficient on these small systems. You said, “I''m convinced that a good value holding plate system is far more efficient to live with; Isotherm is one excellent product example of this”.
There are many good systems out there with options to fit all boaters needs. I hope everyone needing a refrigeration system for their boat will watch the slide show on my web site. http://www.kollmann-marine.com This is the same presentation I use in my seminars of what works and what does not.
