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

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
