The water entering your home journeys through a system of tubes, usually cold or cold, depending on the time of year. To get warm enough water to take a bath or shower in hot water, or to use a dishwasher or washing machine, you need a water heater.

Water heaters are a familiar fixture in most homes. They usually look like large metal cylinders, tall drums that are often placed in a laundry room or basement. Newer styles have some interesting features, such as completely losing the tank in favor of water on demand, but the old, reliable and widely used water heater design in the USA today is really a very simple device; It is a cylinder filled with water and equipped with a heating mechanism at the bottom or inside. Although it lacks drama and sophistication, the water heaters are still pretty amazing. What makes it interesting is that it exploits the principle of high heat to deliver hot water directly to your faucet with minimal fuss. Don't let the simple look of the wool insulating blanket fool you. The water heaters have an innovative design on the inside for something that looks very ordinary on the outside.
In the following pages, we'll dive into a little hot water and take a closer look at what's really going on in the large steel enclosure of the water heater downstairs.
Inside the water heater
Let's take a quick look at the ingredients that work together in a water heater to make your morning shower so satisfying:
Tank - The inner shell of the water heater is a heavy metal tank that has a waterproof liner that holds 40 to 60 gallons (151 to 227 L) of hot water at about 50 to 100 pounds per square inch (PSI), within the pressure range of a typical residential water system . The outside of the tank is covered with an insulating material such as polyurethane foam. On top of that, there's a decorative outer wrap and maybe an extra insulating blanket.
Diving tube - The water enters the water heater through the dip tube on top of the tank and travels to the bottom of the tank where it is then heated up.
Shut-off valve - the shut-off valve stops the flow of water to the water heater. It is a separate component from the heater located outside and above the unit.
Heating Tube - Hanging towards the top of the inner tank, the heating tube allows hot water to exit the water heater.
Thermostat - This is a thermometer and a device for controlling the temperature. Some electric water heaters have a separate thermostat for each component.
Heating Mechanism - Electric water heaters have heating elements inside the tank to heat the water. Gas water heaters use a burner and chimney system instead.
Drain valve - Located near the bottom of the outer casing, the drain valve facilitates emptying the tank to replace items, remove sediment, or move the tank to another location.
Pressure Relief Valve - This safety device keeps the pressure inside the water heater within safe limits. |
