The water heater is an essential appliance in every household because of its many uses. It provides you with hot water all over your home, causing it to work continuously. But, the constant running of the water heater also puts a lot of strain on the plumbing system. An experienced electrician can help maintain your water heater to best enjoy it, particularly during the cold weather.
How Does a Hot Water System Work?
Every time you wash the dishes, do the laundry, shower, etc., the heater works to get the water with the ideal temperature through the pipes to its destination. The journey of the hot water starts from the main pipe toward the sink, washing machine, shower, or dishwasher.
The most common types of hot water systems in residences are electric and gas. They mainly operate using the same principle but differing in their sources of heat. No matter what heating mechanism you are using, it follows this process:
As water travels through the water main pipe, the line splits into two different ways just before reaching the water heater. This makes up the water intake system of your residence. For example, when you turn on your hot water tap, cold water will pass the shut-off valve and enter the water heating tank, which will instantly become warm.
The bottom of the tank has a heating mechanism that heats the water as per the thermostat setting. The water that enters the tank is displaced to the bottom part, while the hot water rises at the top. Hot water at the top of the tank is displaced under immense pressure, as new cold water gets inside the tank. This hot water journeys through the heat-out pipe in the direction of your hot water tap.
Tankless Water Heaters
The tankless water heater is an option that is growing in popularity. A tankless heater heats water only when you need it, instead of storing water in a constantly heated tank. A flow sensor activates when you turn on the hot water tap. If you have a gas-powered tankless water heater, the sensor activates a fan, opens the gas valve, and fires up the bure, as the fan draws air in.
If you have an electric tankless unit, the sensor triggers an electric heating unit. In either type, the unit warms up the heat exchanger inside, heating the water to a preset temperature. The water passes through the tank to the tap. This removes the need to store hot water and maintain a high temperature continuously.
Tankless water heaters provide homeowners with many benefits. They minimize the risk of leaks, save energy, and do not have a limited supply of hot water, especially when it is in high demand. Since there is no need to deplete any tank, a tankless unit does not run out of hot water. These tankless water heaters are also longer lasting and much safer to use.
Schedule of Maintenance
When you know the basic principles, it is not too complicated to understand how a water heater works. If your water heater needs some maintenance, or you are having a problem with it, you need a reliable electrician Brisbane to help you with it. Keep in mind that even the best parts of the unit will wear down over time, particularly when put under continuous pressure.
When you have a new water heater at home, it is advisable to flush your unit every week for at least the first few months in order to wash out any sediment buildup. The presence of sediment may clog the lines and reduce the lifespan of the water heater.
Examine the condition of every component of the unit from couplings to the hose and look for any damage. Check the tank for any leaks and corrosion in the plumbing joints. Test if the pressure relief valve works steadily and smoothly. It is essential to regularly check the pressure of your heater. A water heater tank can normally hold a 100psi pressure. If it exceeds that figure, the pressure relief valve may break and get damaged.
Additional Maintenance Tips for Your Hot Water System
Do not switch on your water heater for a long period of time. This is because keeping the unit for extended periods can shorten its life. Instead of putting it on for half an hour before, it makes more sense to switch it on only for about 5 minutes before.
Observe the plug of your unit. Using low-capacity wiring on the power socket and sudden power fluctuations could cause the switch to spark once in a while, requiring you to call your local electrician to look at the matter. A higher electricity wattage may heat up the plug and its pins, which will leave burn traces. Make sure to use new plugs and sockets that are correctly plugged in and wired to prevent electrical short circuits in the future.
You can save electricity when you lower the temperature of your water heater. A lower temperature setting means the water will reach the desired temperature faster and the unit has to work less, which helps increase its life. In addition, having warm water lowers the risk of accidental burns, rather than getting extremely hot water.
Use metal outlet and inlet pipes instead of plastic ones. This is because metal pipes are more resistant to heat compared to those plastic pipes. Also, perform a regular inspection of the joints. If there are some white deposits around the joints due to rust or hard water, call a licensed electrician because it is time for a replacement.
Bigger water heaters usually have anode rod inside for anti-corrosion. This rod attracts impurities such as rust in the water, which helps prevent the tank from getting corroded or rusted. It is recommended to check the anode rod before winter and every few years or so to find out if more than 6 inches of the inner steel core is visible and the outer layer of magnesium has corroded away.
If you lack knowledge in doing maintenance work on a water heater and want to avoid problems with it, it is better to hire a professional electrician to do the job rather than trying to do it on your own. The specialist can also help with cleaning the unit.
