Ensuring a reliable and uninterrupted hot water supply is a priority for every Singaporean household, making water heater installation services indispensable. Whether for bathing or cleaning purposes, having access to hot water when needed is a key aspect of daily life. However, families may encounter a common issue where water heaters disrupt the circuit breaker, leading to an unreliable hot water supply. 

Recognizing the inconvenience caused by these interruptions, it is essential to delve into the root causes of water heater circuit breaker trips and implement effective preventive measures to ensure a reliable and hassle-free hot water experience.


Common Factors Behind Circuit Breaker Trips in Instant and Storage Water Heaters

Burnt Heating Element:


One of the most common reasons for a tripping circuit breaker in a storage water heater or instant water heater is a burnt heating element. This issue often arises due to mineral buildup on the element, leading to overheating and damage. Regular maintenance and descaling can help prevent this, ensuring efficient and safe water heating in both instant and storage water heaters in Singapore.

Faulty Thermostat:

Another issue you may encounter among storage water heaters and instant water heaters is a faulty thermostat. A malfunctioning thermostat can cause the water heater to overheat and trigger the circuit breaker. For both instant and storage water heaters, it’s crucial to check and replace faulty thermostats promptly to maintain optimal temperature control and prevent electrical issues.

Bad Breaker Or Wiring:


Poorly functioning breakers or faulty wiring can lead to frequent circuit trips. Ensuring that the breaker and wiring are in good condition is essential for the safety of instant and storage water heaters like the 707 Protek Instant Water Heater and Champs SLB15 Storage Water Heater, preventing electrical hazards and ensuring consistent hot water supply.

Water Heater Leak:


A leaking water heater can create electrical problems and pose a safety risk. Regular inspections to identify the reasons behind water heater leaks and prompt repairs are vital to safeguard both instant and storage water heaters in Singapore, maintaining their efficiency and preventing circuit breaker issues.

Overloading the Circuit:

Overloading the circuit with multiple appliances can also be a reason for a tripping circuit breaker in an instant water heater or storage water heater. Balancing electrical loads and avoiding simultaneous heavy appliance usage can prevent such issues, ensuring the uninterrupted operation of water heaters in Singapore.

Ground Faults:

Ground faults, such as a short circuit to the ground, can lead to circuit breaker trips. Regularly checking for ground faults and addressing them promptly is also essential for the safety and proper functioning of water heaters, whether it’s instant water heaters or storage water heaters.

Corrosion or Loose Connections:

Corrosion or loose electrical connections can disrupt the proper functioning of a water heater, potentially leading to circuit breaker trips. Understanding the reasons why the water heater is corroding and loosening connections is crucial to avoid further escalation of such instances. Therefore, regular inspection and maintenance are essential for the longevity and reliability of instant and storage water heaters in Singapore.


Tips To Stop Instant/Storage Water Heaters From Tripping The Circuit Breakers

Inspect Water Heater Regularly


One of the main reasons why the water heater trips the circuit breaker is that there is a problem with the water heater itself. A water heater is made up of multiple components. Regardless of what water heater brand you own, the failure of one component, like a damaged tank, can cause a short circuit. For older water heaters, the wiring is often damaged due to pests biting the wires, or the insulation being lost. 

Therefore, if you are wondering how a 707 storage water heater prevents a water heater from tripping the circuit breaker, it is advisable to regularly inspect the water heater for any visible damage, such as rust or leaks. The heater can also be tested to check which specific part is malfunctioning. 

Avoid Overloading Your Circuit Breaker


Circuit breakers are important in all homes. Ideally, having various power-hungry appliances running all at the same time should be avoided to prevent your circuit breakers from tripping. Since a water heater (e.g. Champs A15 Pro Storage Water Heater) has one of the highest electricity consumption in your home, it is best to switch off any other appliances that consume high electricity like washing machines, dryers, and aircon while using it. You can also consider installing an energy efficient water heater.

Safety Maintenance Checks On Water Heaters


Like all appliances, the performance of a water heater degrades over time naturally. If you have been using your current water heater for more than three years, Enterprise Singapore advises that you have your water heater regularly serviced by licensed technicians to deal with any water heater issues and maintenance. The technician will first clean the water heater to remove any dirt and grime that may have built up. He will then inspect the water heater and repair any components or wiring if he finds any problems. 

Flushing to Remove Sediment Buildup

Over time, one of the common problems among water heaters is the sediment buildup. This can occur particularly in areas with hard water. Flushing your water heater is a crucial maintenance task to eliminate sediment deposits that can compromise heating efficiency. Regular flushing helps maintain optimal performance, extends the lifespan of the unit, and reduces the likelihood of tripping circuit breakers.

Singapore is known to have one of the cleanest water sources globally. Yet, it’s important to recognize that water can still pick up impurities during its journey to our homes. Without adequate filtration, these impurities make their way into our water heaters, where they can linger and cause issues over time. The fact that HDBs and apartments make it a point to regularly clean their water tanks shows just how important it is to address this issue. While it might not be practical to flush your water heater every year, installing a pre-filter can be a proactive step to keep those impurities out in the first place. 

Annual Water Heater Draining

An annual draining of your installed water heater is essential for preventing corrosion and enhancing its overall efficiency. This practice is especially crucial in Singapore, where the humid climate can contribute to accelerated wear and tear. Draining removes accumulated debris and sediment, reducing the risk of clogs and extending the life of your instant or storage water heater. By incorporating this simple yet effective maintenance step, residents of Singapore can ensure their water heaters operate at peak performance throughout the year.

Clutter Management for Safety

One thing to consider when buying a new water heater is the space available. Inadequate space around your water heater can pose potential hazards. However, if you already have a water heater installed, it’s crucial to manage the clutter around it. Ensure that the area is free from flammable materials and that the unit has proper ventilation. This proactive approach not only enhances safety but also reduces the risk of overheating and circuit breaker tripping. Regularly check the surroundings of your water heater to guarantee a safe operating environment.
