Hot water systems are one of those essential parts of every Melbourne home that we often don’t think about — until something goes wrong. But how long should a hot water system last? And what signs should you look out for when it might be time for a replacement?
Let’s break it down.
How Long Should A Hot Water System Last?
Most hot water systems are built to last anywhere between 10 to 15 years, depending on the type of system you have, how often it’s used, and whether it’s been well-maintained over the years.
That being said, some older systems might push beyond this with regular servicing, while others may need replacing earlier if they’ve been under strain.
Factors that impact a hot water system’s lifespan
Several things can affect how long your hot water system will last, including:
- The type of hot water system (Electric, Gas, Heat Pump, or Solar)
- The water quality in your area (hard water can lead to faster corrosion)
- How much hot water does your household use daily?
- Regular maintenance and servicing
- Installation quality
In Melbourne, for example, water quality is of good quality compared to some parts of Australia. This can prolong the life of our hot water systems.
Is maintenance an important factor?
Absolutely! Regular maintenance is often the difference between a hot water system that lasts 15 years versus one that struggles to get past 8.
Simple maintenance like:
- Checking the pressure relief valve
- Cleaning the pilot and burner assembly.
- Cleaning filters
- Getting professional servicing every couple of years
This can help prevent small problems from becoming expensive repairs or complete system failure.
The average lifespan of hot water systems
Here’s a general guide on how long different types of hot water systems usually last:
| Hot Water System Type | Average Lifespan |
|---|---|
| Electric Storage | 12 to 15 years |
| Gas Storage | 12 to 15 years |
| Heat Pump Hot Water | 10 to 15 years |
As you can see, Heat Pump Hot Water Systems offer similar life spans to traditional hot water systems with better energy efficiency, making them a smart long-term investment.
