priming the loops

i got my heatpump FHP 2 ton with ECM blower

and some solar goodies outback vfx3648 3600 watts 48V grid tied battery backup inverter, outback fm80 80A charge controller, and midnight solar's combiner box. got this as a bonus from my boss.

im going to run 4kw dc to it

i drew up some plans for doing a ground mount

while priming my loops the temp gauge remained at 72*F

i built ducting out of 3/4'' foam board, i just have to finish a 15' run in the attic

i ordered some more parts for my priming setup. what im going to do is hook everything up minus the loop pump and use a ball valve to choke down the priming pump output to 8 gallons a minuet and check the pressure at the pump output from there i can perfectly size the circulator pump needed

Man, that's one busy weekend! Very Nice work on the duct-work!!
Looks like you are going be making the power to run that system too..

thank you i got antsy and decided to test run my unit with the priming pump, i got great results. i wired the loop pump into the compressor relay.
thermostat i stole off my wall

this is the pressure with the pump at full blast

heating mode temp return from loopfeild

heating mode temp to loopfeild

cooling temp return from loopfeild

cooling temp to loopfeild

i just need to devise a scheme to measure the gpm and then check the pressure so i can get a proper pump
