Continue reading to discover five tell-tale signs that you need a new hot water system.

Leaking Hot Water System

I’ve recently experienced this issue with my own hot water system – Yes, plumbers having plumbing problems too! If you see water leaking from the top of the tank or your tank is sitting in water, then there’s a very strong chance that you’ll need a hot water system replacement very soon.

You should call your local Auckland plumber, iSpecialise, as soon as possible if you are experiencing this sign.

Running out of Hot Water

If you’re running out of water or find your water not reaching the temperatures it once did, then this too is a sign that you need a new hot water system. Not enough hot water or warm water is often a result of a thermostat problem. In some cases, the thermostat can be replaced, but in older systems, it is best to replace the entire system.

Noisy Hot Water System

If your hot water system is making noises; whether it be popping, hissing, crackling, banging, or rumbling, it could be a sign of a severe problem. A hot water system shouldn’t be making any unusual noise. So if yours is, it needs the attention of a plumber stat!

Noise is often a sign of a heating element problem where sediment forms on the bottom of the tank. The sound you hear is steam bubbles breaking through the sediment build-up.

A noisy hot water system is energy inefficient. It takes longer to heat water and will cost you more to run.

Rusty Water

Another sign that your hot water system is on the blink is visible rusty water leaking out of the tank, and in some cases, taps also. Rusty water is usually a sign that your hot water system is at the end of its lifespan and is due for replacement.

The appearance of rusty water shouldn’t be ignored, nor should you delay in calling a plumber. It can damage your washing machine and dishwasher and should be addressed immediately by a qualified plumber. In most cases, you will be looking at a hot water system repayment, that is unless the rust us coming from your pipes and not your tank. iSpecialise can determine this for you.

An Old Hot Water System

Another sign that you need a hot water system is less of a sign and more a matter of age. If your system is more than ten years old, then chances are it’s come to the end of its lifespan.

You should only expect to get around ten years from a hot water system. So even if your system isn’t leaking or making noises, it will be less efficient and likely fail sooner than later.


There are various tell-tale signs that a hot water system replacement is on the horizon. If your hot water system is leaking water, producing rusty water, running out of hot water, making noises, or is more than ten years old, it’s likely time for a new hot water system.
