6 Signs Your Hot Water System Needs Replacing

We all love our hot water systems, they provide us with a life necessity and frankly, we couldn’t live without them. From gas to solar, storage to continuous flow, there are many types and sizes of hot water systems installed in homes all across Australia. When your hot water system is having problems, it can become a serious inconvenience to your life. Look out for these six warning signs.

Warm/Cold Water

When a hot water system’s only job is to create hot water, it’s an obvious warning sign if it simply isn’t doing that. You may find mildly warm or even straight-up cold water flowing from your taps. The reason it may be doing this could be one of many. There may simply be an issue with the gas or electricity supply that feeds it, but this is rare. It usually comes down to faulty, defective or simply worn out heating elements or thermostats. Often parts for hot water systems can be pricey and depending on the age of the unit, it is usually best to replace the whole system.

Age

This is an obvious one. Like any household appliance, hot water systems have a limit as to how long they can last. Most units from top brands in Australia will outlive their warranty, but it depends on many factors. Climate, usage, water quality and location all factor into how long a unit can produce hot water reliably. Most units have a warranty somewhere around 5-10 years depending on the brand, model and size. This is a good general ballpark figure, however, it shouldn’t be taken as gospel.

Noise

No one likes a noisy home appliance. It can disturb your peace as well as the neighbours and hot water systems are no exception. The most common cause of a noisy hot water system is simply loose or worn out parts. It could be rattling, hissing, screeching, banging, there’s a whole lot of noises a machine can make. They aren’t designed to be whisper quiet by nature, but if it’s creating a serious disturbance to your life every time you turn on the hot water tap, get a professional in to look at it, because you may need a new system.

Rust and Corrosion

This is possibly the most damning sign that your system needs replacing. You can’t fix a rusty or corroded system. Rust causes parts and fittings to crack and begin to leak, which can then let the rust into your water. This can be dangerous for your health. If you notice your water is a browny, reddish colour, cease use of it altogether. Rusty parts generally aren’t replaceable, so your best bet here will be a brand new system. Rust and corrosion can be caused by elements like the climate as well as water quality.

Leaks

Leaks are so often dismissed as a non-issue. People think that a little bit of water dripping won’t hurt them. That water adds up, and if not attended to, can cost you hundreds in water bills. Leaky hot water systems are a common perpetrator. Leaks can be caused by faulty parts and fittings, or simply old and worn-out ones. If your system is leaking excessively, it may be time to move on.

Increased Demand

Have you been adding to the family? Maybe your 12L continuous flow system was adequate when it was just you and maybe your partner, but once kids come along, the demand increases and your hot water system may not be able to keep up. If you find that doing the dishes while your kids shower and the washing machine is on leaves you with very low water pressure and lukewarm water, your hot water system isn’t fit for the job anymore. You can upgrade to bigger sizes with ease, with continuous flow models going up to even 30L, nearly tripling your hot water delivery.

So what system should I get then?

Had my toilet replaced on Friday. They arrived on time and went above and beyond to finish the job professionally given it was a lot harder than first thought. Our plumber was fantastic. Would definitely use again.
