Hi Hv23t,
It's about 57F down at the A7 right now. I don't think it's going to get much cooler during the winter.
(It's 35F outdoors right now).

That general area around the A7 can drop down to 55F while it's running,
but the area warms back up a few degrees pretty fast.

I guess it's the slightly warm floor of the basement warming up the air.
So, my A7 ASHP is really a ground-source Geothermal unit..

Maybe I should drill some holes in the floor and implant some long heat-pipes?
Of course they would be dripping wet during the summer months..

Haha, I just shot my IR pistola down into the sump pump holes,
and the temperature two feet under the basement floor is 57F.

The year-round average temp here is 54.3°F and that does have
a large effect on the upper few feet of soil..
So, maybe we'll see the floor drop down to around 54F,
but I'm pretty sure the A7 won't notice it much..
