Question: “How long do hot water systems last?” Answer: “Hopefully forever!” Indeed, while a great Melbourne plumber can fix you up with a brand-spanking-new system for a great price, let’s be honest – money doesn’t grow on trees. We’ve all got enough to pay for along with our mortgages and bills and a little on the side for fun, so it’s probably wise to know how long that investment in your current hot water system will be suitable for.

So how long do hot water systems last? It’s not quite a question like “How long is a piece of string”, but the truth is that the answer remains quite tricky – as it depends on a number of factors.

What are these factors? Ezy-Plumb’s Melbourne hot water plumbers answer:

1. The Quality

When you go to the best plumbers and hot water specialists in town, you can rest pretty easy that you’re going to get one of the best systems made by the best brands installed at your place. As with anything, you tend to get what you pay for, so beware of ultra-cheap brands promising the earth. The cheaper systems, after all, are the ones that are more likely to corrode. The best brands include Rinnai, Rheem, Aquamax and Thermann.

2. The Material

Another reason the cheaper hot water systems are more affordable is that they’re made of more inexpensive materials. A good quality glass or enamel-lined system, however, should last a good ten years or more, while you’ll get a few more years than that if you go for a premium stainless steel model. Remember, corrosion is the number 1 cause of hot water system failure, so the better the material, the longer it will last.

3. The Type

Don’t forget, ‘hot water system’ is a catch-all phrase, a little like the word ‘sport’ is – meaning there are different types of hot water systems. “How long do electric hot water systems last” is, therefore, another question to “how long do gas hot water systems last” – and the same is true for your instantaneous heat pump and solar options. Generally, a storage electric hot water system should last marginally longer than a gas equivalent. At the same time, you’ll get more life out of an instant gas hot water system (and save on bills) – because it’s simple and doesn’t store corrosion-causing water.

4. Your Usage

The longevity of a hot water system is intricately tied to the amount and frequency of hot water usage. The more hot water you use, the harder your system has to work to meet the demand, which can accelerate wear and tear. Prolonged periods of high usage, such as long showers or frequent hot water appliance usage, can cause the heating elements and components of the system to degrade faster.

Conversely, a hot water system used sparingly may have a longer lifespan. Regular maintenance and servicing can also play a crucial role in extending the life of your hot water system, regardless of usage patterns. Therefore, being mindful of your hot water consumption and ensuring proper maintenance can significantly impact your hot water system’s length.

5. The Water Quality

It’s also important to note that the water pumped in and out of your system isn’t pure H2O. When the water is less pure, hot water experts refer to it as ‘hard water’ – with a higher concentration of dissolved calcium, magnesium and other minerals. And when hard water is heated up, those dissolved minerals can carbonate, becoming solid and damaging your system. The good news is that regular professional maintenance helps with this.

The Verdict: How Long Do Hot Water Systems Last?

So if you want to take a number to the bank, you can expect your new hot water system to last between 7 and 15 years – which, unsurprisingly, is broadly in line with the standard warranties offered by the manufacturers. To try to push your system’s lifespan up, we recommend regular checks and servicing.
