5 Critical Signs Your Storage Water Heater Needs Replacing

In the humid climates of Singapore, having a functional and efficient water heater is not just a luxury but a necessity for daily comfort. Storage water heater , which store a significant volume of heated water for use, are particularly popular in many homes across the island. However, these units do not last indefinitely and often show clear signs when they’re nearing the end of their lifespan. Recognising these signs can save you from unexpected breakdowns and costly emergency replacements. Here are five signs that your storage water heater in Singapore needs immediate replacement.

1. A very old heater

The lifespan of a typical storage water heater ranges from 5 to 15 years, depending on the brand, and if installation is done in accordance with the Code of Practice. In Singapore, where water is generally not hard, so mineral build-up is rare however if your water heater is approaching or has surpassed the ten-year mark, it’s wise to consider a replacement. The efficiency of water heaters diminishes with age, leading to higher electricity bills and reduced performance.

Eventually leaking will occur. Corrosion at the inner tank causing it to leak is the by far the most common failure in a storage heater. It happens from 2 years to 20 years after the installation.

2. Electric Tripping

“Tripping” Causing tripping of the whole house electrical system when the heater switch is turned on.

A faulty heating element in the electric storage heater can cause the entire house’s electrical system to trip. Here’s why this happens:

Electrical Short Circuit: If the heating element in the water heater develops a fault, such as a crack or breakage, it may lead to a direct short circuit. This occurs when the electrical current bypasses the normal circuit pathway and instead flows along an unintended path. This sudden surge in electricity can overload the circuit.

Ground Fault: A ground fault occurs when there is an unintentional electrical path connecting a power source to a grounded surface. If the insulation around a heating element deteriorates, it can cause the electrical current to leak to the ground. This leakage might also occur if water comes into contact with the electrical components, which is possible in appliances like water heaters. This abnormal path causes a significant surge that trips the circuit breaker.

Circuit Overload: Heating elements draw a considerable amount of power. If there is a fault in the element, it may draw more current than the circuit can handle, leading to an overload. This excessive demand for current heats up the wires and the circuit breaker, which is designed to trip and cut off the power to prevent the wires from overheating and potentially causing a fire.

Safety Mechanisms: Most electrical installation in Singapore are equipped with circuit breakers, notably the Residual Current Circuit Breakers (RCCB). These devices are designed to detect any abnormal flow of electrical current and disconnect the power rapidly to prevent damage and ensure safety.

Therefore, if your home experiences frequent tripping and you suspect it might be linked to a faulty heating element in any appliance, it is advisable to consult a qualified electrician who can diagnose and rectify the problem. This ensures both the safety and efficiency of your home’s electrical system.

3. Rusty Water

If you start noticing rusty water coming from your hot taps, it could be a sign of corrosion inside your water heater tank.

Most heater models come with various kinds of coatings for the inner tank, such as Rheem with RheemGlas™ vitreous enamel glass lining, Ariston with titanium enamel, and Joven with solid stainless steel. Once the inner tank coating is compromised, rust may develop. The user may notice brownish water coming out from the hot water side of the tap; though not harmful, it can have an odor.

In Singapore’s high humidity, the risk of corrosion is exacerbated, and once the tank starts to rust, there is a risk of leaks or a tank burst. It’s crucial to check not just the water, but also the condition of the inlet and outlet connections. Rust on these components can also indicate that the internal condition of the tank is compromised.

4. Water Leaking Around the Heater

Water pooling around your heater is a clear indication of a leak. Leaks can be due to various reasons such as a cracked tank, loose fittings, or a faulty temperature and pressure relief valve. In Singapore’s compact residential spaces, a leaking water heater can cause significant damage to your property. Ignoring such leaks can lead to false ceiling damage, mold growth, and increased water bills, making it imperative to address this issue promptly.

5. Inconsistent Water Temperature

If you’re experiencing fluctuating water temperatures, or if your water is not heating sufficiently, it’s a sign that your water heater is failing. This could be due to a malfunctioning thermostat, a broken heating element, or sediment build-up inside the tank. Inconsistent water temperatures can be particularly troubling during the cooler months or when sudden temperature dips occur in Singapore due to monsoon rains.

Conclusion

Whether you seek Ariston, Joven or Rheem water heater repair, timely replacement of your water heater can ensure you continue to enjoy hot water without interruption and prevent damage to the surrounding architecture. Keep an eye on these signs and consult with a PUB Licensed Plumbing company to determine if your storage water heater needs replacing. Replacing a storage heater is regulated work. Although it may be cheaper to have it carried out by a handyman, the associated risks are high.

Using a PUB Licensed Plumber will not only ensure your daily comfort but also enhance the safety and efficiency of your household’s hot water supply.
