Unfortunately, nothing lasts forever and that includes your hot water system. Hot water is a resource that we want and need every day. It is something that we take for granted. Instantly heated or previously heated hot water is something that we have come to expect in this modern age. Hot water systems aren’t something that we give a thought to. You just turn on the tap and there it is. That is until something goes wrong and all you’re getting is cold water!

We have such a reliance on this resource that it can be seen as a major disaster when that happens. The best way to avoid this sudden shock is to have your hot water system regularly maintained and when it is time, promptly replace it. We at Galaxy Hot Water Plumbing & Gas would like to give you a heads up on the signs you need a new hot water system.

Here’s how to know it’s time to call us.

Old Hot Water System

One of the biggest indicators that it’s time for a new hot water system is if your existing one is very old.

With proper care, your hot water system should last at least 10 years, sometimes longer.

But if your system is more than 10 years old, it’s time to start considering buying a new one before you have a problem.

You can figure out how old your system is by checking the serial number. 

Overworked hot water systems are liable to break down. You can get it fixed, but replacement is usually a better option because something starts to break down, including hot water systems, they usually continue to degrade, with one thing after another. It may be that you’ve outgrown the system. In other words, the family has expanded and the hot water usage has increased. Your boiler hasn’t the capacity anymore and sediment inside the tank builds up, making the whole system work harder.

You Hear Noises

In general, you hot water heater shouldn’t be making noises.

If you suddenly start hearing strange sounds, you might need a new system.

As your system ages, sediment gathers at the bottom of the tank. As the water heats, the sediment hardens and causing banging or rumbling noises.

Those signs mean the tank is nearing the end of its life and you’ll need a new one soon.

You Have Rusty Water

Another sign is murky or rusty looking water coming out of your taps; a sure sign that all is not well. Your boiler or pipework may have become corroded. Noisy or banging pipes may be an indication of this. Hopefully, it is just the boiler, which is easy to replace. Replacing pipework can be a nightmare. 

When you turn on your tap, the water should be clean and clear.

It shouldn’t be rusty. If it is, it’s a good sign that your hot water system needs to be replaced and upgraded.

Rust in your water is a result of corrosion in your hot water tank.

Sometimes you can fix this problem, but most of the time you’ll need to have the system replaced.


Leaks are another and hard to ignore sign. It’s not uncommon to have a leak. Most systems will leak over the course of the years. If you have a sudden flood, a burst or cracked pipe, it usually time for a replacement. Small, persistent leaks will quietly damage your home too. 

If your hot water system is more than ten years old, it is time to think about replacement. Most systems are only designed to work at maximum capacity for a certain number of years. This depends on the kind of hot water system you have had installed or inherited when you bought your house. If you don’t know, check out the boiler. There should be a manufacturer’s sticker with a serial number and date.

You Don’t Get as Much Hot Water

If your hot water system isn’t heating the water, it’s not doing its job.

And that likely means it’s time to start considering a new one. As your hot water system gets older, it won’t do as good of a job heating the water.

If you notice that you aren’t getting as much hot water as you once did, your hot water likely needs to be replaced.
