For my Cerakote curing oven, I normally turn it on and get it to 250F which takes about an hour. Opening the face/door and loading it cools it down to 80-90 (air) and then it's about 30 minutes to 250F again and then 2 hours for bake.
You can also run Cerakote at 300F for 1 hour. Tried that today. Took just under 2 hours to get to temp, down to 80 (air) loading and then 1 hour back to 300F and then 1 hour for curing.
My sense is it's cheaper to run it at 300F. How can I calculate the electrical draw while it's warming up? It's fairly stable, turning on and off, to maintain temp though I haven't recorded how many times and how long each time it does turn on to maintain 250 or 300 over a period
