Depending on the size of the storage water heater tank, home appliances mostly have low power consumption. Storage water heaters usually have their own electrical circuit breaker, which cuts off the electricity supply when it exceeds the current safety limit. 

Homeowners have to turn on the circuit breaker just to use the storage water heater, and sometimes, the circuit breaker trips. When this happens, it affects the settings and how your storage heater works. If you’re experiencing a circuit breaker after a water heater installation, read the following tips to learn how to fix the problem. 


Burnt Heating Element 

The number of the heating element present in the water heater depends on its size as you read the online guide to an electric water heater and its elements. If you have an old or poor-quality storage water heater, the heating element incurs damages over time due to the high temperature and substandard materials used. 

The heating element heat resistance lowers while increasing the power consumption, causing the breaker to trip. It’s one of the problems with your water heater that you should keep in check. You can safely check the issues by using a multimeter for the resistance. When there is a change in the resistance rating, it is a sign that the storage heater or the heating element has been damaged. 


Defective Thermostat 

One of the common issues with storage water heaters, old and of low quality, is a faulty thermostat. You can find the thermostat connected to the power supply. Usually, a thermostat will cut off the power supply to the heating element if the temperature is above the preset temperature. When the thermostat stops the power supply, it also prevents the water from getting heated further. 

If the thermostat is defective, it will heat the water leading to high power consumption. When this problem becomes unattended, your circuit breaker will trip, so always check your thermostat with a multimeter when you see signs of water heater failure from water temperature.


Defective Breaker or Faulty Wiring


Some users don’t troubleshoot or call for water heater services when their circuit breaker trips when using their storage water heaters. Instead, they keep turning on the switch, which can damage their circuit breaker entirely.

Circuit breaker trips are not all related to storage water heaters. Sometimes, it could be caused by component damages, leading to breaker trips even below the specified current limit. When this happens, the wiring connecting the breaker to the water may incur damages from heating. Mice and cockroaches eat exposed insulation, causing a short circuit. When this happens, you may need a water heater repair or even replace it with the best storage water heaters in Singapore.


Leaking Water Heater


Another reason for circuit breaker trips is water heater leaks. When the gasket and pipes become loose or other parts develop holes, you can usually see and identify water heater leaks

Water can cause short circuits and, worst, tripping your circuit breaker. It is a conductor of electricity; thus, it is best to check it with a professional from Everyworks Singapore. You can also note it to keep expert water heater technicians safe and provide a speedy, professional service during a water heater installation.
