ABSTRACT:
A portable electric water heater for supplying a continuous flow of hot water for outdoor home use includes an impact resistant waterproof housing having a coiled water conducting cooper tube disposed therein and wrapped with an electrical resistance heating element. A manually operated rheostat adjusts the heating current received through a power cord from a standard 110 Volt current source. The tube has a cold water inlet and a hot water outlet adapted to fit standard garden hoses and faucets. Wheels and legs support the housing and a handle facilitates movement thereof. Alternate smaller versions employ skid runners or caster wheels for portability and may have conducting tube sections positioned in a horizontal plane adjacent a respective heating element.
Each embodiment utilizes an on/off toggle switch and a flow responsive pressure switch in series with the rheostat. A pop-off valve is also provided. The rheostat is arranged in circuit to permit preheating of the water by a minimum current flow when the flow switch is open due to lack of water flow through the tube.
