Thanks for the suggestions! All of the boat's shore power system is brand new, she previously only had DC power. I agree that the electric heaters scare me too. However, it looks like you still have to plug the oil heater in. Sorry if this sounds silly, but how are the two different in that department? What makes the oil heater safer if it is still part electric? (Originally from AZ, don't need many heaters there!) I do have some of the small propane heaters also.
