I'm trying to remember correctly now, I don't think the loop input temps hit the low 20's but for was in the 20's. Out temps were low 20's, maybe even down to 18 and was getting concerned. At some point the pump faulted out as it started to freeze the liquid. Nice fail safe features on these things. Added another 5 gallon of antifreeze and it didn't happen again. In any case, the second stage was disabled last winter because there just wasn't enough loop to support it. I hope to stay in a more efficient range as far as loop temps go this winter.
2700 sq ft.

How many SQ feet are you heating?
Thanks for all the info.
