<p>This Architectural Drawing is Details of EWH of toilet. EWH = <strong>ELECTRIC WATER HEATER. </strong>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. Having two heating elements that run independently, dual-element water heaters are <strong>typically more energy-efficient than their single-element counterparts</strong>. Using less electricity can help lower your monthly energy bills and be better for the environment. For more details and information download the drawing file.</p>
