How Do Electric Hot Water Systems Work?

May 11, 2020

There will be times when the outside temperature drops as the season changes. In combating this type of situation, we ensure that our hot water system is installed and ready to go. Whatever type of hot water system you own, it would still regulate and heat the temperature of our water supply, which is very useful for our daily chores and activities.

Hot water systems are intended to keep your household water continuously hot and ready to use. These systems may run on electricity, natural gas, propane, heating oil, solar, or other energy sources. One of the most used hot water systems in households is run by electricity.

Features and Benefits

Electric hot water systems utilise electricity to process and heat the water. With an electric hot water system, the water is naturally heated by electric elements. The whole system is also plugged into a power supply.

Hot water systems that are run by electricity usually come in both storage and continuous flow varieties. They can also be off-peak types that contain two heating elements. With an off-peak type, the bottom element is responsible for the heating during off-peak hours at night. The upper element, on the other hand, does the heating if you run low on hot water supply during the day. These two elements have separately controllable thermostats that allow for different temperature settings.

Many households use electric hot water systems because of numerous reasons. The costs of purchase and installation of hot water systems are often cheaper than the others. They can also be installed indoors or outdoors. Electric hot water systems also come in a range of sizes, making them suitable for any area of a home.

Water Heating Process 

The water heating process of electric hot water systems can be breakdown into simple steps. An electric hot water system brings cold water in through the dip tube and heats it using the heating elements that are found inside of the tank. Once the heating is done, the hot water then rises in the tank and will be moved throughout the household by the heat-out pipe.

To help the system run safely and efficiently, the whole electric hot water system has some parts that can also be found on other types of hot water systems. An electric hot water system has an ever-reliable thermostat, which allows a homeowner to freely set their desired water temperature. It also has an insulated tank where the whole water storage and the heating process takes place.

For protective measures, this hot water system has a temperature and pressure relief valve that will release water from the tank if the water temperature is too hot. It also releases water if the pressure inside the tank is beyond the normal level, preventing any instances of hot water system explosion. Another protective measure that can be found on an electric hot water system is the drain valve. This valve is usually located on the side of the tank that helps drain the system to reduce the accumulation of sediment. One maintenance tip is that you must drain your hot water system once a year.

An electric hot water system has a sacrificial anode rod, which is a metal rod that prevents the tank from rusting. This type of metal rod will take the rusting process instead of the metal found on the hot water system tank. This anode rode, however, must be replaced every 1 to 2 years.

Heating the water with an electric hot water system is deemed to be effective and efficient. This type of system also ensures that your safety is prioritised all the time.
