Having no hot water can quickly become a problem, especially when you rely on your system every day. If your hot water system is not working, there are several possible causes depending on whether you have an electric, gas, heat pump or solar system.
Before arranging a repair, there are a few basic things you can check.
1. Check whether the system has power
If you have an electric hot water system, check whether the system’s power supply or isolation switch has been switched off.
You can also check your home’s switchboard to see whether the relevant circuit breaker has tripped.
If the system repeatedly trips the circuit breaker, avoid continually resetting it. There may be an electrical fault that needs to be investigated by a qualified professional.
2. Check your circuit breaker
A tripped circuit breaker can prevent an electric hot water system from heating.
If the breaker has tripped once, it may be worth checking whether it can be safely reset.
However, if it trips again, there may be an underlying electrical issue.
At this point, professional assistance is recommended rather than repeatedly resetting the breaker.
3. Check whether you’ve simply used more hot water than usual
Sometimes a system is working normally but the household has used more hot water than usual.
This can happen when:
- Guests are staying at your home
- Showers are longer than usual
- More people are using hot water
- You are doing additional laundry
- Household routines have changed
If the system produces hot water again after its normal heating cycle, the problem may be related to household demand rather than a system failure.
4. Look for visible leaks
Check around the tank, pipe connections and valves for signs of leaking water.
A small amount of condensation can occur in some circumstances, but a persistent leak should be investigated.
If the storage tank itself is leaking, the system may require replacement rather than a simple repair.
If you’re unsure about the source of a leak, avoid dismantling the system yourself.
5. Check your gas supply
If you have a gas hot water system, check whether other gas appliances in your home are operating normally.
A problem with the gas supply can prevent the hot water system from operating.
Gas appliances should only be inspected or repaired by appropriately licensed professionals.
6. Look for changes in temperature or unusual noises
A system that produces inconsistent water temperature, unusual noises or insufficient hot water may have a problem with one of its components.
Depending on the system, possible causes can include issues with the heating element, thermostat, controls or other components.
The exact cause can only be determined by properly assessing the system.
7. Consider the age and condition of your system
Sometimes the issue isn’t simply whether a system can be repaired.
You also need to consider whether continued repairs make sense for an ageing system.
If your hot water system is old, repeatedly breaking down, leaking or no longer providing enough hot water for your household, it may be worth comparing repair and replacement options.
You can browse available hot water systems to compare replacement options.
When should you call for hot water repair?
If you’ve checked the obvious issues and still don’t have hot water, it’s time to have the system professionally assessed.
You should also arrange an assessment if you notice:
- Water leaking from the system
- Repeated circuit breaker trips
- Gas-related problems
- Unusual noises
- Inconsistent water temperature
- A sudden change in hot water performance
Trying to repair electrical or gas components yourself can create unnecessary safety risks.
If the system can be repaired, a professional can identify the faulty component and recommend the appropriate repair.
If the system is approaching the end of its useful life, you can also compare hot water replacement options.
