First of all we need to understand the meaning of boiling.
Boiling can be understood as the action of raising the temperate of a liquid to the point when it bubbles then vaporizes. The boiling point of water at sea level is 212°F or 100°C. Boiling can also be understood as rapid vaporization which occurs when a liquid is heated to its boiling point.
Therefore, from the definition of the word boiling we can derive the conclusion that it is not possible to boil water without heating.

Is it possible to change ice to vapor:
The process of ice changing to vapor is known as Sublimation.
Sublimation is the process where a solid substance can transition directly to vapor without having to pass through the liquid state. The best common example is dry ice which is solid CO₂. In the case of water, frozen water can sublime under special conditions like under reduced pressure or in a vacuum just below the melting point temperature. At this point the frozen water should turn into liquid water, it can sublime but needs special environmental conditions.

The extra heat supplied to the boiling water is used in the vaporisation of water, which is known as latent heat of vaporisation. That's why, the temperature of a substance remains constant during its melting or boiling point. hope it helps you ;)
