Thanks for the complements on the TXV hack. I will admit the compressors pressures are alot more consistant as the head side temps change thru the day. What should I try to increase my heating capacity.??
When the cap tube was installed and running 24/7 I had to reduce my charge to keep the loop-side HX from freezing. Of coarse if I had added the propylene glycol this wouldn't happen.
But if I understand what Vlad was speaking of its heating we are after and not the cooling side. We need to optimize the heating capacities of the unit and what occurs on the evaporation side is less of a concern as long as its picking up enough heat.

With the new TXV do I have an overcharge?? Hopefully I haven't maxed out the capacity of my GSHP. By comparison the commercial unit in my home @ 3 tons drawing 12A is heating a larger area. And the hacked compressor was rated at 3.5 ton and drawing more current and less heat.
