My goal for the swap was to minimize the upper radiator hose length.
Yep per. That’s why we put it down there originally. But…. If it was in upstairs garage instead I might power it for free (“prepaid“ actually lol as it’s been pricey!) then additional power consumption certainly would not matter In the warmer ambient condition.It could be argued that the basement freezer runs more efficiently in the basement due to the more stable and cooler temps. Not sure I'd bring it upstairs.
Then again, efficient isn't necessarily the the goal here. Free is the goal (after payback, of course). I'd certainly want to know the system is being used and in top working order, and the freezer would be a way to go about it.
