In a typical Brisbane household, hot water is used dozens of times a day, often without a second thought. While it's easy to take it for granted, knowing how your hot water system works can help you maintain your heater for longer. It also helps you explain any issues to plumbing experts clearly, so they can fix problems faster.
Below, we’ll discuss how hot water systems work, what their components are, as well as tips for keeping your hot water system in top shape.
Components of a hot water system
Most hot water systems, whether gas or electric, have the following components:
- Tank — This is where your water is stored and heated. Gas heaters warm the water from the bottom, while electric ones use heating elements inside the tank.
- Thermostat — This controls the water temperature in the tank. On electric systems, you can usually adjust it to your liking. For gas systems, it's typically part of the gas control valve.
- Heating element/burner — In an electric heater, the heating element (or elements) is responsible for warming the water. In gas systems, a burner located at the bottom of the tank serves this purpose.
- Dip tube — This pushes cold water to the bottom of the tank, keeping it separate from the hot water at the top. It helps ensure you get hot water when you need it.
- Heat-out pipe — This pipe draws the hottest water from the top of the tank and delivers it to the taps when needed.
- Pressure relief valve — This is a key safety feature that releases water if the pressure gets too high inside the tank. It's important to check this regularly to make sure it's working correctly.
- Anode rod — This rod attracts corrosive elements in the water, protecting the tank. Checking and replacing it when needed can significantly extend your heater's life.
How does a hot water system work?
Now that we've identified the key components, let's explore how they work together to provide the hot water we rely on daily.
When you turn on a tap, cold water enters the tank through the dip tube, which directs it to the bottom of the tank. The heating element or burner then warms the water to the desired temperature, controlled by the thermostat. As the water heats up, it rises to the top of the tank, ready to be delivered through the heat-out pipe.
As hot water leaves, it creates space for more cold water to enter at the bottom, continuing the cycle. The pressure relief valve stands guard, ready to release excess pressure if needed, while the anode rod works silently throughout, protecting your tank from corrosion and extending its lifespan.
The operation of a hot water system is generally straightforward and trouble-free, especially if professionals are overseeing everything from setup to servicing.
