What Are the Most Reliable Brands of Hot Water Systems?

Hot water systems are some of the hardest working appliances in our homes. You probably don’t even think about the heater that’s humming away in the background. That means it’s often a surprise when a hot water system kicks the bucket. People often find themselves replacing their hot water heater on short notice, and they’re left trying to figure out which systems offer the best value. The most important thing to think about here is longevity. A hot water system that delivers efficient heating and a long lifespan is going to offer the best bang for your buck. In this article we’ll explore the most reliable brands of hot water systems and how you can prolong the life of your unit.

What Brand of Water Heater is the Most Reliable?

There are dozens of hot water brands on the Australian market. The good news is that most modern systems are fairly reliable. If you’re looking for the best performance though, it’s worth investing in a system from one of the following brands:

Signs Your Hot Water System is Failing

All hot water systems need to be replaced eventually. Luckily, most high quality systems will last for a decade or more, so you won’t need to install a new unit any time soon. In between regular maintenance appointments you should keep an eye out for the following signs that your hot water system is failing:

  • Unreliable supply of hot water
  • Hot water runs out too quickly
  • Rust or corrosion on the tank, pipes or fittings
  • Water leaks from the tank
  • Murky or brown hot water
  • Strange noises or smells coming from the system

If you notice any of these issues then it’s time to contact your plumber. In some cases they may be able to fix the issue without having to replace the entire system. Just keep in mind that a hot water system will typically last about 8-12 years. If yours is getting older, it might be cheaper to install a replacement rather than paying for repeated repairs.

How to Prolong the Life of a Hot Water System

Hot water systems are a serious investment. If you don’t want small problems to turn into a big repair bill, the best thing you can do is keep an eye out for the signs we mentioned above. If you’re experiencing issues with your hot water heater, it’s time to book a plumbing maintenance appointment.


Most hot water heaters are simple appliances, but they still need servicing from time to time. A yearly maintenance appointment with a professional plumber can dramatically increase the lifespan of your system. During your regular appointment, your plumber will inspect each component for signs of leaks or rust, test the electronics, flush the tank and check the anode to make sure it’s still in good condition. These simple checks provide peace of mind and ensure that your hot water system will always be ready when you need it!
