Jeff, yes I have long past stopped trying to ask local people questions, they really have no idea other than what the factory tells them or what can make the most money. I only know one honestish company around.
So a 12-15F subcooling may not be the target because this is a custum system. That makes sense.
I did adjust my charge back to 230psi discharge simply because when it switched to air heating mode my pressures were higher than I would like.
So I am wasting power by increasing charge. I think you are right the middle reading does seem the best so far.
The power draw of each reading was 680 watts, 710 watts, 760 watts. I did not calculate the btu/hr yet. Been having some really cold nights.
The temp never drops less than 64.5F before the compressor kicks on.
Does it make sense that I larger compressor would help, or are you saying that my condenser is already maxed out? I can easily add an extra loop if needed. I just want those .5kWh nights back. lol
