  • Heating system for heating fluid in a tank
    Patent number: 9719729
    Abstract: A heating system for heating fluid in a tank includes a heating device for heating and pumping water to a tank heater via a hose. The tank heater has a pump connected to a heat exchanger. The heat exchanger has a plurality of tubes disposed in a housing that receive fluid from the tank. The heating device pumps hot water through the heat exchanger to transfer heat to fluid in the tubes and the back to the heating device. The pump circulates fluid within the heat exchanger.

  • Ground heating device
    Patent number: 7441986
    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.
