ABSTRACT:
A ground heating device is provided for thawing frozen ground. A water heater is provided with a reservoir tank in fluid communication with the water heater. A pump is provided in fluid communication with the reservoir tank. A hose is provided in fluid communication with both the pump and the reservoir tank. Additionally, the ground heating device includes a spool for winding the hose. In this arrangement, the water heater maintains hot water in the reservoir tank, and the pump circulates the hot water from the reservoir tank, through the hose, and back into the reservoir tank. The hot water thaws the frozen ground that is proximate to the hose.
