Process: (The images in this video do not necessarily display this entire process)

• A hydraulic press creates round shape and forms the base of the tank
• The tank body is welded together
• Fittings are welded in by a projection welder
• The tank top is welded into place
• Liquid enamel is sprayed inside the tank and baked at an extremely high temperature to form a protective coat
• The base and flue are attached to the tank
• Tank is then tested to see if there are any leaks
• For an electric tank the elements are installed next, then the thermostat
• The water heater casing is formed
• The top and bottom edges crimped so the top and bottom lids can be fitted properly
• The casing is placed over the inner tank
• Polyurethane insulating foam is inserted between the shell and the inner tank to insulate the water heater
• For a gas tank, the gas burner is installed at the bottom of the tank, then tested for gas leaks
• Final touches, such as labelling are then performed
