If you own a hot water tank, you may be wondering how often it needs to be serviced. Regular servicing is important to ensure optimal performance and safety of your hot water system.
However, the frequency of servicing may vary depending on the type of hot water tank you have.
Electric/gas storage hot water tanks should be serviced every 5 years, while continuous/instantaneous flow tanks should be serviced annually. Heat pump and solar hot water tanks should also be serviced every 5 years.

These are just guidelines, so always refer to your manufacturer’s recommendations for servicing your specific hot water tank.
During a hot water tank service, a licensed professional like Hot Water Plumber Warragul will inspect and clean various components of your system, including the heating element, thermostat, and pressure relief valve. They will also check for any signs of wear and tear, leaks, or damage.
Regular servicing can help extend the lifespan of your hot water tank and prevent costly repairs down the line.
Understanding Hot Water System Maintenance
Regular servicing of your hot water system is crucial to ensure its safety and longevity. In this section, we will discuss the importance of regular servicing, the different types of hot water systems, and how to identify your hot water system.
Importance of Regular Servicing
Regular maintenance of your hot water system is necessary to ensure that it operates safely and efficiently. It is recommended that you have your hot water system serviced at least once a year by a licensed plumber.
Servicing your hot water system can help to identify and fix any potential safety issues, such as gas leaks or faulty electrical connections. It can also help to improve the performance of your system, which can lead to lower energy bills.
Types of Hot Water Systems
There are several types of hot water systems available, including solar hot water systems, heat pumps, continuous flow, and electric/gas storage. Each type of system has its own maintenance requirements.
- Solar hot water systems: These systems use energy from the sun to heat the water. They consist of solar panels or collectors that absorb sunlight and transfer the heat to the water. Solar hot water systems should be serviced every 5 years.
- Heat pumps: These systems work by extracting heat from the air or ground and using it to heat the water. Heat pumps should be serviced annually.
- Continuous flow: These systems heat the water as it is needed, rather than storing it in a tank. Continuous flow systems should be serviced annually.
- Electric/gas storage: These systems store hot water in a tank and are the most common type of hot water system. Electric/gas storage systems should be serviced every 5 years.
Identifying Your Hot Water System
To identify your hot water system, you can check the manufacturer label located on the unit. You’ll see the model and serial number, which can help you determine the type of system you have.
If you’re unsure about the type of system you have or when it was last serviced, it’s recommended that you contact a licensed plumber like Hot Water Plumber Warragul to inspect your system.
Service Intervals and Procedures
Recommended Service Frequency
To ensure that your hot water tank continues to operate efficiently and safely, it is recommended that you have it serviced regularly. The frequency of servicing your hot water tank may vary depending on several factors, such as the type of hot water system you have, the water quality in your area, and the manufacturer’s recommendations.
As a general rule of thumb, you should have a minor service conducted on your hot water tank annually, and a major service every 5 years.
However, it is important to check your manufacturer’s recommendations and warranty requirements for specific servicing intervals.
Key Maintenance Tasks
There are several key maintenance tasks that should be performed regularly to keep your hot water tank in good working order. These tasks include:
- Checking the pressure relief valve: This valve is designed to release pressure if it builds up inside the tank. It should be checked regularly to ensure that it is functioning correctly and is not leaking.
- Checking the sacrificial anode: This rod is designed to attract corrosive elements in the water and protect the tank from rust and corrosion. It should be checked regularly and replaced if necessary.
- Flushing the tank: Sediment buildup can reduce the efficiency of your hot water tank and cause strange noises. Flushing the tank regularly can help to remove sediment and improve performance.
- Checking the temperature setting: The temperature setting on your hot water tank should be checked regularly to ensure that it is set correctly. A setting that is too high can be dangerous, while a setting that is too low can lead to bacterial growth.
Professional Servicing vs DIY
Some maintenance tasks can be performed by the homeowner. However, it is recommended that you have your hot water tank professionally serviced at least once a year by a qualified and licensed plumber.
A professional technician will have the knowledge and experience to identify any potential issues and perform any necessary repairs or replacements.
DIY maintenance can include checking the pressure relief valves and anode rod, as well as flushing the tank. However, make sure to follow the manufacturer’s recommendations and safety guidelines when performing these tasks.
Regular servicing of your hot water tank can help to prolong its lifespan, improve energy efficiency, and ensure that it is operating safely.
By following these key maintenance tasks and having your tank professionally serviced as required, you can enjoy reliable hot water for years to come.
