Not sure, possibly below freezing in the Load 100' buried & insulated loop between HP in shop & house, if HP is not used for some days.

Another option to glycol would be to have a small pump circulate 24/7 in heating season?
I would prefer this to elemonate the glycol and to elemonate a flat plate HX in house.
This would also elemonate the higher viscosity pumping penality with glycol.
