No, it is not a chemical reaction. The added heat only drives the water molecules out of the crystal structure. No bonds are made or broken.

Actually, it is a chemical change, because there are bonds between the water and CuSO4. by heating, these bonds are broken, there is a color change not coming from the reactant.
