It was a warm hurricane. All hurricanes are tropical by definition.
Hurricane Sandy was a hurricane because it was a large scale tropical system with a closed circulation, a defined center of rotation, organized convection, a warm core, and sustained winds in excess of 74 mph. All these are needed to qualify as a hurricane. However, at landfall in the U.S. Sandy had lost tropical characteristics, and so was technically no longer a hurricane but a very powerful post-tropical cyclone.
No, warm water fuels a hurricane
Moisture evaporates from the water. The resulting warm moist air carries enormous amounts of energy. When this air is pulled into a developing hurricane it rises and as a result cools and condenses, releasing that energy.Energy of a warm sea is transferred to a hurricane by water evaporating into a hurricane.
A post tropical cyclone is a cyclone that was once tropical (i.e. a hurricane or tropical storm) that has lost tropical characteristics such as a warm core, but stil retains its circulation.

The fuel of a hurricane is warm, very moist air. The moisture is provided by warm ocean water.

A hurricane increases its speed when it is over warm water.
For a Hurricane to strengthen it needs tropical,warm water!

The Earth's mantle is a plastic substance which undergoes convection due to the heat of the core. Warm material rises up from near the core to just under the crust. The heat that it carried from the core is released into the crust, thus warming the surface. The cooled material then descends back to the core.
A post tropical cyclone is a cyclone that was once tropical (i.e. a hurricane or tropical storm) that has lost tropical characteristics such as a warm core, but stil retains its circulation.
Generally speaking the greater the depth of the warm water, the stronger the hurricane can get. Is is because a greater depth means a greater volume of warm water to supply energy for a hurricane.
The eye of a hurricane is actually warm, though there is not exact temperature.
