One of the most common issues with your gas hot water system involves interruptions with the gas supply or a faulty thermostat. A consistent power supply is crucial for reliable water heating; without it, your system cannot function properly.
Moreover, a faulty thermostat can lead to overheated water, posing a scalding risk, or cause the system to fail in heating the water.
Begin troubleshooting by checking for tripped circuit breakers that may have caused a power loss. If your thermostat is not within the recommended range, carefully recalibrate it and retest after 30 minutes.
Test the water temperature – it should typically not be set too high and remain in the 120°F to 140°F (50°C to 60°C) range.
Ensure your electrical connections and thermostat functions are in proper working order. If you encounter any complex issues, such as tempering valve malfunction, don’t hesitate to call your team of licenced plumbers at Strathfield Plumbing on 1300 349 338 for prompt assistance.
Heating elements and the heat exchanger play a crucial role in electric hot water heaters. They ensure you can use hot water heated to your desired temperature setting, stored within the tank. Faulty or worn heat exchangers are among the reasons why an electric system stops being able to supply water at the right temperature.
Determine if your electric hot water system requires servicing by examining the heating element:
Before addressing potential water heater issues and testing your heating element, switching off power to your heater at the main circuit breaker can help prevent electric shocks. A faulty element can short out or electrify the water, potentially causing further issues. Water then should be drained from the tank to safely access the element, ensuring the flow sensor is not obstructed while avoiding exposed wires.
Visually inspect your hot water heater’s element for signs of water damage like corrosion, mineral deposits or cracks from being used over time. Use a multimeter to check the electric resistance level – a faulty element will show readings that are too high or too low. If you’re unsure about the results, don’t hesitate to call plumber experienced with hot water systems for advice.
If your water heater has two heating elements, test both to ascertain which requires replacement. replacement elements for water heaters, in many cases, must match your system’s specifications for wattage, voltage, material type and thread dimensions for proper fit.
For professional troubleshooting of your unit and replacement of faulty heating elements, which could mean your system needs attention, in Strathfield, Sydney, call the licenced team at Strathfield Plumbing on 1300 349 338.
Sediment from mineral deposits can accumulate in your water heater tank over time. This sediment layer can cause your water heater to become more than inefficient, it raises energy bills, and shortens the usable lifespan.
Periodic flushing to clear sediment buildup is an essential maintenance task. Flushing enhances performance and prevents early system failure.
Flushing your electric hot water heater, after you shut down the power, involves carefully draining the storage tank, removing accumulated mineral deposits with a strainer valve and sediment, then refilling it with fresh water. As a safety measure, turn off the power at the main circuit breaker before draining electric hot water heaters.
For the best results, get professional flushing every 1-2 years by qualified plumbers such as Strathfield Plumbing.
Our technicians use high-pressure flushing for superior sediment removal, ensuring appliances in your home maintain a continuous flow.
Low water pressure and corrosion can lead to significant issues that affect your hot water unit’s performance over time. When a leak appears coming from the base of the heater, it clearly indicates potential problems, while corrosion appears as rust spots or stains on the exterior of the tank.
To check for any water leaks, start by inspecting all water connections, valves, pipes and joints for drips, moisture or lime buildup. Also look for any cracks in the tank itself. You may notice water coming out your way from small leaks only while the system is heating and under pressure.
Corrosion results from the reaction between water and the steel tank liner, a common issue in older heaters. Replacing the anode rod every 5 years helps protect the tank. Advanced corrosion may indicate a need replace the tank, as it weakens the integrity and can lead to leaks or even catastrophic ruptures.
For comprehensive leak checks and repairs, especially for loose components, the team at Strathfield Plumbing has the experience, equipment and expertise to locate the source, thoroughly fix any leaks and replace components if needed - whether it’s valves, pipes, anodes or even an entire heater tank in some cases.
