We have a dozen open (no doors) cooler sections in our food courts at a convention center. These coolers sit empty but running about 70% of the time, sometimes for a few days, but more often for a few weeks.
The food courts are temperature controlled to never go below 65F when not in use and most of the time is 80F when not in use.
There are no hand controls on these units. Put power on and the rest is automatic.
I would like to simply turn the power off the units when not in use and turn the breaker on when needed.
One of my fellow workers wants to install oil heaters and controls for these units.
With ambient temperature never being below 65F, oil heaters seem like over kill. There are no heaters installed, but with no doors, the cycle rate keeps everything pretty warm.
What do you think? Heaters or no heaters?
