I incorperate preheating/maintenance when I play. After I fire my first torpedoes I have two free slots, I load one of them so that one tube is empty and one internal storage is empty. every now and then I will pull out one of the torpedoes and then put it back in again (maintainence) repeating for any electrics in the tubes.

For preheating I load a tube (since I had that empy tube mentioned earlyer) which pretty much simulates the time to preheat a torpedoes battries
