Thermann Hot Water System Troubleshooting

Therman Hot Water System & No Hot Water

If your Therman hot water system operates on gas and you have no hot water, you should check if the pilot light is lit and the gas burner is functioning. To do this, remove the access cover at the bottom of the unit and turn the control knob to the 'Pilot' setting. Hold the control knob down for about 30 seconds and press the igniter button repeatedly to light the pilot. Once the pilot is lit, hold the knob for an additional 60 seconds before slowly releasing it to ensure the pilot flame stays lit. If the pilot stays on, switch the knob to 'On' to activate the heater. Listen for the main burner igniting and check for a steady blue flame, indicating proper function. Replace the access cover after confirming everything is working. See full guide on how to re-ignite a pilot light here. If you encounter persistent issues with the pilot light or cannot light it, consider consulting a professional technician, as there may be more complex issues with the system.

Power issues are a common cause of circuit breakers tripping, so it's a good idea to check your circuit breaker if you're experiencing electrical problems. This can often be the first step in troubleshooting electrical hot water systems. If you find that the breaker has tripped, resetting it may resolve the problem. However, if it continues to trip, this could indicate a more serious issue, and you might need to consult a professional electrician.

Check and replace the electric elements of your Thermann hot water system, as these elements may deteriorate with time and usage. Remember, when electricity and gas are involved, it is always best to leave it to trained professionals. Regular maintenance will keep your Thermann hot water system working for longer and avoid costly repairs.

Electric components that may need replacement in a Thermann hot water system include heating elements, thermostats, anode rods, and element gaskets.

(1) Heating Element is responsible for heating water, but it can burn out over time due to sediment build-up or wear, which can diminish their efficiency or stop them from working altogether; (2) The Thermostat controls the temperature of the water by switching the heating element on and off. A malfunctioning thermostat can lead to water being too hot or not heating at all; (3) Although not an electric component directly, the Anode Rod is critical in preventing corrosion inside the tank. Its deterioration can lead to tank damage, which can indirectly affect the system's electrical components; (4) Element Gaskets seal the heating elements to prevent water leaks. As time passes, gaskets can degrade, and it may be necessary to replace them to maintain a proper seal.

Thermann Hot Water System & Water Too Hot

If your Thermann hot water is too hot, this could be due to excessive water supply pressure, a faulty Pressure Temperature Relief (PTR) valve, or a malfunctioning thermostat. 

Turn off the water heater to prevent any further risk of overheating or pressure build-up. After shutting down the system, contact either Thermann's service line for specialised assistance or consult a local plumber in your area. Professional plumbers can diagnose the problem and make the necessary repairs, ensuring that your system operates safely and efficiently. Handling such repairs on your own is not recommended due to the complexities involved with gas and electrical components.

Thermann Hot Water System is Leaking

The pressure relief valve or the temperature valve on your Thermann hot water system are designed to release water as a safety measure, so dripping water is normal. If you notice a significant amount of leakage, it could be a sign of an underlying problem. You can often address this issue yourself by gently lifting the valve lever and then releasing it just as gently. This action might help clear any debris that's causing the leak.

If the leakage doesn't stop, or if you find that your hot water system is leaking from other areas, turn off the heater to stop the flow of water, and contact a professional plumber Adelaide. Making a service call ensures that a qualified technician can assess and repair any problems, ensuring your system is safe and functioning correctly.

Thermann Hot Water System & Discoloured Water

The discolouration is often caused by rust or sediment accumulating in the tank or pipes. This can occur naturally over time, especially in areas with hard water. The issue could often be fixed by draining and flushing the tank to remove built-up sediment. Another potential cause is the corrosion of the anode rod, which is designed to prevent rust inside the tank. Inspecting and replacing the anode rod if it's significantly worn can also help clear up water discolouration. It's always best to consult a professional plumber, as the discolouration could also be linked to more complex plumbing issues.

Thermann Hot Water System & High Energy Bills

If you've noticed higher energy bills and you're using a hot water system, increased hot water usage could be a significant factor. Electrical hot water systems can account for up to 27% of a household's energy use. The more hot water you use, the more electricity is required to heat it, leading to higher bills. 

If your hot water system is leaking, it will use more energy to heat the water. Addressing leaks in your plumbing can prevent unnecessary water wastage that can inadvertently increase energy consumption. Moreover, installing a four-star, energy-efficient showerhead can significantly reduce the amount of hot water you use without compromising your comfort.
