Hot water tank venting
New home and this water tank is in an upstairs closet that backs up to the attic and a bathroom. I am not sure what the cut out is for up top or the bottom (that side is against the bathroom).
Question: is the large hole in the ceiling necessary?
Issue: hot air from the attic is pouring out of the hole and coming thru the closet door. You can feel the heat off the door and it causing our upstairs AC to never hit its set point. We want to try to keep the louvered door, but also recognize it’s not helping keep the heat inside.
