200F is a low temp, the heat will be off probably 95%+ of the time. I would
expect the electric used for 4 hours isn't all that much. Sometimes I want
an oven temp of say 120 or 150F for some project. The lowest setting on
the oven is 170F. So I have to monitor it to get the right temp. It takes very
little on time to raise the temp and you can easily overshoot.

You might hold that temp with a light bulb in there.
