Abstract: A device for reopening an ice-bound water source is disclosed. Once a hole is provided in a frozen water source, the tubular member is inserted into the hole where it becomes frozen in place. The ice block which will form in the interior region (28) of the tubular member can be ejected. The tubular member itself is heated by a fluid circulating and heating means (62) which runs heated fluid between the walls (20 and 22) of tubular member (12). The heated fluid allows for release of the ice block and dislodgment of the entire unit from the frozen surface of the water supply.
