Shalom,
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.
Regarding the coconut oil, you can check on the OU or CRC website for updated information.
