A working hot water system is a comfort and convenience essential in any home. When your system starts to fail, whether it’s inconsistent water temperature, strange noises or visible leaks, the question is: should you repair or replace?
We outline the key points to help you make an informed decision based on cost, efficiency and long-term value.
Age of the System
The average life of a hot water system is 8 to 12 years. Systems under 8 years old are often worth repairing, especially if the issue is minor. Systems approaching or over 10 years old are less efficient, and replacement parts may be harder to find. In this case, replacement may be the more cost-effective option.
Nature of the Fault
Some faults can be fixed with a simple repair, while others indicate more serious damage or wear.
Repairable issues:
- Faulty thermostats
- Broken heating elements
- Leaking pressure relief valves
- Tripped circuit breakers
Indicators that replacement may be more appropriate:
- Rusty water (especially from storage tank systems)
- Water pooling at the base of the unit
- Frequent or recurring breakdowns
- Unusual noises (banging, rumbling)
- Inconsistent hot water output or low pressure
If repairs become a recurring expense, it may be more cost-effective to invest in a new system.
Energy Efficiency
Older systems are less energy efficient and will cost more in the long run. Upgrading to a modern energy-efficient system can save you a lot of money, especially in high water usage households.
Options:
- Electric or gas storage systems
- Continuous flow (instantaneous) systems
- Solar hot water systems with electric or gas boosters
- Heat pump water heaters
Choosing the right system depends on household size, water usage patterns, energy source availability and long-term running costs.
Cost Comparison: Repair vs Replacement
