So yeah, the heat pump works in the cold. With the low-abmient kit the unit is rated to work down to 4 degrees. Yesterday when I went out in the morning it was -10 outside, the storage area of the barn was down to 30 and this room was 67 so yep, it was working. This was with lights out and no dehuey running.
My big room I don't use the heat pump, the Santa Fe keeps the room at least 68 regardless of outside temps.
Thank You Thank You .... both of you
i've got your unit linked for later , it sounds like its perfect for what i want to do !!! & yes i'll remember the low-ambient kit , gonna need it here , even inside if its unheated .
