5 Signs You Should Replace Your Water Heater

Want to enjoy a home that is as comfortable as it is functional? Of course you do. One essential component of a functional and comfy home is a reliable, working hot water system. We use it each and every day for everything from showering to washing dishes and doing the laundry. 

Over time, however, water heaters can begin to show signs of wear and tear. As they age, they can become inefficient and ineffective - especially if they’ve not been well-maintained. They may even suddenly break down on you completely - which is the last thing you want in the middle of your morning shower! So knowing the signs to look out for that indicate your water heater is due for a replacement might help get you one step ahead before it’s too late. 

Let’s take a look at 5 of the most common indicators that your water heater is nearing the end of its lifespan.

No. 1: The Age of the Water Heater

As we’ve mentioned, the age of your hot water system is one of the biggest telltale signs that it may need replacing. 

Most water heaters typically last you a good 8 to 12 years. There can be variances between gas, electric and solar-powered systems, however, and even between instantaneous vs storage hot water systems. 

As hot water systems get older, they become less efficient and more susceptible to breakdowns and other issues. If yours is within or beyond this age range, it may well be time to consider replacing it. Check the serial number on the unit to determine its age; manufacturers often encode the production date within this number. 

It’s well worth being proactive and replacing your old system before it’s too late. You can avoid the hassle of sudden failures and maintain a reliable supply of hot water for your home.

Sign 2: Rusty Water

Ever turned on the hot water tap, only to have rusty or discoloured water start flowing through? It’s the last thing you want to see and is a strong sign your hot water system might be on its last legs. 

If you have a storage tank system, rust in your water usually means that the inside of the tank is corroding. And that corrosion will only get worse over time. There is also the possibility that rusty pipes could be the issue, though, which means pinpointing the exact culprit is essential. Does the rust only appear only when you’re using the hot water tap? In that case, the water heater is likely the issue. 

Rust and corrosion inside the hot water tank can lead to leaks and eventual failure. Addressing this early can save you from potential water damage and the inconvenience of a faulty water heater. Regular inspection and maintenance can help catch these issues before they become severe.

Sign 3: Noisy Operation

Unusual noises coming from your storage water heater, such as rumbling, popping, or banging, are often signs that something is amiss. These sounds typically indicate a buildup of sediment at the bottom of the tank. 

As the sediment heats up and hardens in the tank, it can cause the water heater to work harder. This results in system inefficiency and potential damage. There are ways to minimise the buildup of sediment, such as flushing the tank regularly. However, if the noise persists, an imminent system replacement might be on the cards. 

Over time, sediment build-up can strain the water heater, leading to cracks and leaks that compromise its integrity. Getting on top of these noises ASAP gives your home the best chance at continuing to enjoy reliable hot water. Without the unexpected disruptions.

Sign 4: Leaks Around the Hot Water System

Number 4 in our “warning signs that it’s time to replace your hot water system” rundown is the presence of leaks. Even the smallest water leaks can snowball quickly, leading to significant damage throughout your home. 

In storage tank systems made of metal, leaks often occur due to the metal expanding, particularly as the heater ages and performs endless heating cycles. Additionally, corroded pipes or connections can also cause leaks. 

It’s well worth inspecting the area around your hot water system regularly - this can help you catch leaks early. Should you discover puddles or moisture around the unit, address them quickly. Fixing minor water leaks might provide a short-term solution, but a persistent problem usually signals that you’ll need a new water heater sooner rather than later. 

Sign 5: Inconsistent Water Temperature

Erratic and inconsistent water temperatures are the reddest of red flags, telling you that your water heater is nearing the end. 

If you find that your hot water runs out quickly or fluctuates between hot and cold unexpectedly, it’s clearly telling you something isn’t right. This could be due to:

• malfunctioning heating elements

• a faulty thermostat within the unit

• sediment buildup insulating the water from the heating elements

Though maintenance and repairs might resolve some issues, stubborn and persistent problems typically signal the need to replace your system. 

Importance of Using a Licensed Plumber

When the time comes to replace your hot water system, using a licensed plumber is not just a helpful recommendation - it’s a legal requirement. 

Aside from the legalities, a licensed plumber can help you in many ways.

• They have the expertise and knowledge to correctly and safely install your new hot water system.

• Plumbers comply with strict local building codes and regulations, which is essential for both your safety and compliance with legal standards. 

• They’re also able to provide qualified, expert advice on the best type of water heater for your home.

• A reputable, licensed plumber will also back their work with a warranty. 

Attempting to install a water heater yourself or hiring an unlicensed handyman might save money initially, but it can lead to costly mistakes, potential damage, and voided warranties. Trusting a licensed plumber guarantees peace of mind and ensures your new water heater operates efficiently and safely.

Keep Your Home Efficient, Comfortable and Functional

Recognising the signs that it’s time to replace your water heater can save you from unexpected hassles and expenses. 

Whether it’s the age of your hot water system, the presence of rust or leaks, or one of many other notable indicators, taking a proactive approach is the best way to keep your home supplied with hot water. 

Don’t wait for a complete breakdown of your hot water system before you decide to do something about it. Monitor it regularly, and take action when you notice these warning signs. By doing so, you’ll maintain a cosy, well-functioning home and avoid the inconvenience of sudden water heater failures.
