Does ice formation violate the coservation of energy law?

When water freezes to form ice the volume of water increases with a large amount of force.  The force of the expanding water can even be enough sometimes to crack solid rock.  That force being exerted over time can be expressed as energy being expended.  But the problem is that in the freezing process the heat energy is flowing outside of the water rather than into it.  Therefore, I'm left wondering where does the water get the energy to expand against resistance when the known energy contained in it is being transferred somewhere other than the water that is expanding in the form of ice?  As the ice crystals are forming, are they tapping into some form of zero point energy that the ice crystals use to power their formation that is capable of pushing things like solid rock around?  After all, crystals are used as part of radio reception in some of the old school non-digital receivers.  If you wanted to get some extra frequencies with your police scanner radio, you used to have to get a new crystal that would enable you to get a particular range of the electromagnetic frequency spectrum.  So I'm wondering is, as the ice crystal forms, during that brief period between water as a liquid and as a solid, is the crystal able to tune into and receive some special ZPE frequency that the ice uses to fuel its efforts to expand.  And once the ice is fully formed does the ice crystals then lose the tuning for those ZPE frequencies?  Or another tantalizing possibility is that the ice crystal is still tuning into those free energy frequencies, but are no longer being leveraged by the water molecules to expand ... but perhaps the ice crystal could still be used in combination with some radio receiver circuitry to tap into the ZPE.
