Abstract: A heated water vessel for providing drinking water for animals is provided which has a single wall container, or a dual wall container both exteriors have polymer plastic/metals/rubber with light reactive materials on the container on each and on the second dual wall polymer plastic with light reactive materials exterior container wherein the second walled container is nested within the first, forming an enclosed air pocket between the first, second container. The second dual two containers are sealed together with a breakable waterproof adhesive in order to allow the separation of the containers if necessary. An electric heating printed coil is printed or sprayed around the outer surface of the second container either side or bottom or both and in contact therewith in order to prevent the water within the inner container from freezing over during subfreezing temperatures.
