This Architectural Drawing is of Water Heater Details. An electric water heater works essentially the same way as a gas water heater. It brings cold water in through the dip tube and heats it using the electric heating elements inside of the tank. The hot water rises in the tank and is moved throughout the home through the heat-out pipe. A home with two or fewer people can be served by a 23- to 36-gallon tank. A tank size of 36- to 46-gallons is best for homes of up to four people. A home with five people can be served by a 46- to 56-gallon tank. For six or more people, look at larger tanks with a 60-gallon or greater capacity. For more details and information download the drawing file.
