A livestock watering device which includes a bucket-like container, including side walls and a bottom wall, for holding a quantity of water. A conduit, including an inlet and an outlet, forms a closed loop communicating through the side walls of the container above the bottom wall thereof. The conduit extends in the closed loop below the bottom wall of the container, and a flow-through heater is provided in the conduit for heating water therein and effecting flow of water out of the container through the outlet, through the closed-loop conduit, and back into the container through the inlet. The heater effects the water flow by heat transfer without a pump.
