1. Am I allowed to use electric hot water urn that I use year round on Shabbat, on pesach or do I need to buy new one?
2. How about electric tea kettle?
3. Does organic coconut oil need a hechsher for pesach?
I appreciate it,
You should get both a new urn and tea kettle for pesach. It is likely that chametz got on it, and it is difficult to kosher these items.
