Warming? Not outside!

Manifolds stable 61-68. I have run the 50 gal tank of 120 into the floor 3x and will until the weather breaks. Decent working temp inside but we need HEAT to drive out moisture. 

My initial opinion on the GSHP is lower than expected. The earth water is going out at 22 and returning 32. I think longer pipe or more time in the ground would help.
