ABSTRACT:
A water heater having an electrically grounded water tank including an electrically conductive portion, a water tank inlet and outlet connected to deliver water to and from the water tank, a heater connected to the tank for heating water in the tank, a control for controlling the application of heat to the water, an electrically grounded outer jacket surrounding the water tank, a bottom member electrically grounded to the outer jacket, and a spring urged electrical bonding clip secured to and electrically connected to the bottom member and directly electrically engaging the water tank electrically conductive portion.
A method of producing a water heater which includes a water tank having an electrical connecting portion and a grounded bottom member including the steps of providing an electrically conductive grounding clip on the bottom member, physically and electrically engaging the water tank electrical connecting portion with the grounding clip to thereby position the water tank and the bottom member into position relative to one another in establishing a grounding connection therebetween and positioning an outer jacket around the water tank and into physical and electrical engagement with the bottom pan to thereby provide a space between the water tank and the jacket and grounding the tank to the jacket through the bottom member.
