Not up much on this electric stuff. My AEP guy gave this info:
Single phase to the barn 120 / 240
Our barn is on its own meter.
We ran three calves for 90 days at that rate last year.
Cool room is12’x16’ with a 10’ ceiling. For wall insulation I used 3” foam plus I used rubber roofing on the side walls to make it waterproof. Even with the higher ceiling I think the 3”foam & Rubberized sidewalls made the room more efficient than your average fiberglass/wood sidewalls.
We don’t cool room the calves 24/7. We put them in right before sunrise, and turn them out at sunset. So the unit & fans ran about 14 hours a day on average.
Hope this helps
Nasc!
