Does anyone have an electric burner to recommend that can be left on for a 3 day Yom Tov?
How about this?https://www.target.com/p/coleman-174-1-burner-table-top-butane-stove/-/A-14900808?Light it when you need it and let the can burn out?
Unless its made specifically to be left on for three days I would not use it. I doubt there is such an item, and if you find one I would appreciate you posting back here.
What about putting it on a timer - then it is just on for a few hours at a time
+1 Unless it's an halachic issue?
