Right - that will work fine with a metal hull!<br>

>> Peltier modules ARE more efficient than resistive heaters because they are true heat pumps - they don't supply (all) the heat that they emit on the hot side. In fact, they are more efficient as heaters than as coolers. That said, using them is a lot more difficult than using resistors, because they have to be connected on one side to a heat source and on the other to the area you want heated. In a sub, that sounds like you need another penetration in your pressure hull, which I would not be interested in if it were mine.<br>
