Water heaters are essential appliances in our homes, providing hot water for daily needs such as bathing, cleaning, and cooking. However, like all appliances, water heaters have a lifespan and will eventually need to be replaced. Recognising the signs that your water heater is nearing the end of its life can save you from unexpected breakdowns and the inconvenience of cold showers. 

This blog will guide you through the ten signs that indicate it’s time to invest in a new water heater, specifically focusing on storage unit water heaters, electrical storage water heater units, and instantaneous water heaters. For this reason, consulting a professional plumber in Point Cook can ensure a seamless transition to a new unit.

1. Age of the Water Heater

The age of your water heater is a primary indicator of its condition. Most storage water heaters and electrical storage units have a lifespan of 8 to 12 years. Instantaneous water heaters, also known as tankless water heaters, can last up to 20 years with proper maintenance.

If your unit is approaching or has surpassed these timelines, it’s time to consider a replacement. An aging water heater is more prone to inefficiencies and failures.

2. Rusty Water

If you notice rusty water coming from your hot water tap, it’s a sign that your water heater’s interior is corroding. While it could also indicate rusty pipes, it’s essential to determine the source. 

Rust in the water heater tank often means the unit is deteriorating and may start leaking soon. This is particularly common in older storage units and electrical storage water heaters. A plumber in Point Cook can perform a thorough inspection to confirm the issue.

3. Strange Noises

Water heaters, especially storage units, can accumulate sand, rust, or other water buildup over time. As the build up heats and reheats, it hardens, causing rumbling or banging noises. These sounds indicate that the water heater is working harder to heat the water, reducing its efficiency and potentially leading to cracks and leaks. 

Instantaneous water heaters, while less prone to sediment buildup, can still develop issues that cause unusual noises. Persistent noises are a clear sign that a replacement is necessary.

4. Leaks

Any sign of water pooling around your water heater indicates a leak. Leaks are often a result of internal failures, such as a cracked tank. While minor leaks from fittings or connections might be repairable, a leaking tank requires immediate replacement. 

Ignoring leaks can lead to water damage and higher utility bills due to wasted water. Regular inspections by a professional plumber in Footscray can help detect leaks early.

5. Inconsistent Water Temperature

If your water heater struggles to maintain a consistent water temperature, it’s a sign of an impending failure. This could be due to a failing heating element in electrical storage water heaters or a malfunctioning thermostat in both storage and instantaneous units. If your showers are frequently interrupted by blasts of cold water, it’s time to evaluate your water heater’s performance.

6. Reduced Hot Water Supply

A noticeable decrease in the amount of hot water your heater can produce is another sign of trouble. For storage water heaters, this could mean sediment buildup is taking up space in the tank, reducing the amount of water available for heating. 

In instantaneous water heaters, it could indicate a failing heating element or clogged components. If your hot water runs out faster than it used to, consider replacing your unit.

7. Cloudy or Smelly Water

Cloudy water with a metallic smell often points to a failing water heater. Mineral deposits and sediment in the tank usually cause the cloudiness. These deposits can affect the taste and smell of the water, making it unpleasant to use. 

Instantaneous water heaters can also develop similar issues if they are not regularly maintained. If your hot water has an unusual appearance or odor, it’s a sign that your water heater is damaging and requires a plumber in Footscray for a replacement.

8. Visible Corrosion

Inspect your water heater regularly for any signs of corrosion, especially around the tank and connections. Corrosion is a clear sign that the metal components of your water heater are breaking down. This is particularly common in older storage water heaters and electrical storage units. While minor surface rust might be manageable, extensive corrosion means it’s time for a new water heater.

9. High Energy Bills

An inefficient water heater can lead to unexpectedly high energy bills. As water heaters age, they become less efficient, requiring more energy to heat the same amount of water. Instantaneous water heaters are generally more energy-efficient, but even they can develop issues that reduce efficiency over time. If you notice a spike in your energy costs without an increase in usage, your water heater might be to blame.

10. Frequent Repairs

If you find yourself frequently calling a plumber to fix your water heater, it’s more cost-effective to replace it. Constant repairs are not only inconvenient but also add up in costs. Investing in a new and reliable water heater can save you money and hassle in the long run. 

For residents in Point Cook, a local plumber can provide expert advice on the best replacement options for your needs.
