Electric Water Heater
Electric water heaters are used in many ways around a household for a variety of tasks such as bathing, cleaning, cooking, as well as space heating. However, electric water heaters have been the most reliable and efficient source of heating water for baths especially, but knowing more about its major components makes learning about them even more interesting.
- Tank: this is where the water is contained; it usually holds 40 to 60 gallons of water inside an inner shell. On the tank’s exterior is an insulating material, such as polyurethane foam. Some types of electric water heaters also have an extra insulating blanket.
- Dip tube: where water passes through the unit, located at the upper part of the tank. The dip tube transports the water to the bottom of the tank for heating.
- Heat out pipe: Located near the interior of the tank, this pipe is designed to facilitate passage of hot water from the heater.
- Thermostat: This part of the electric water heater is used to control temperature, so that you can choose varying degrees of heat when you are showering. Some models of electric water heaters are designed with separate thermostats for various elements used.
- Shut off valve: This part is responsible for halting the entry of water into the unit, and is located above the unit outside the heater.
- Heating mechanism: This could be a chimney system or a burner, as various electric water heaters make use of different heating mechanisms to heat the water.
- Drain valve: Found at the bottom of the cases’ exterior, the drain valve allows you to easily empty the tank so you can replace any components that need to be cleaned or fixed, as well as if you have to change the tank’s location.
- Pressure relief valve: This component is integral to the safe usage of any electric water heater because it keeps the pressure within the heater in limits that won’t harm any user.
- Sacrificial anode rod: Designed to be suspended within the tank to slow down and avoid corrosion, and is made up of aluminum or magnesium and a steel core inside.
Now that you know all these parts, they all work together to give you enjoyable and warm showers any time of the day. They all play an important role for safe and efficient water heating.
