Hot water is an essential component of modern-day living, used for cooking, cleaning, and bathing. However, there are times when your hot water heater may fail to produce hot water, leaving you frustrated and inconvenienced.

This can be caused by a variety of factors, including problems with your electric hot water system, a malfunctioning pilot light, issues with water pressure, water temperature or the need to look for “hot water repair near me”. In this article, we'll explore the common causes of hot water failure and offer some solutions to help you get your hot water flowing again.

Hot water & cold water supply

Hot water is an essential element of daily life in every Australian household, providing warmth and comfort during colder months. Unfortunately, hot water issues can be a common problem in homes, and it can be frustrating when hot water is not working while cold water is still flowing. There are various reasons why you’re running out of hot water or may not be working, and understanding these issues can help homeowners troubleshoot the problem and take steps to fix it.

Firstly, it is important to understand the difference between hot water and cold water supply. Cold water is supplied to homes through a main water supply line, while hot water is generated through a water heater system, whether it be a storage tank, continuous flow, electric or gas system.

Most common causes of hot water issues

The most common reasons for hot water supply issues are a faulty thermostat, a defective heating element in a boiler, and a blocked pipe leading to the hot water source.

  • Faulty thermostat: A faulty thermostat may result in the water being too hot or not hot enough.
  • Defective heating element in a boiler: A defective heating element in a boiler or water heater can also lead to issues, including no hot water or lukewarm water.
  • Blocked pipe leading to the hot water source: Blocked pipes that lead to the hot water source can also prevent hot water from flowing through taps and faucets.

How to troubleshoot your system & identify the cause of an issue

If you are experiencing hot water issues, it is essential to troubleshoot your system and identify the cause of the issue. Before calling for professional assistance, check the electrical panel to ensure that the circuit breaker has not been tripped. Ensure that the thermostat is not set too low, and check for any sediment accumulation or mineral deposits in the hot water tank or heating element.

If you cannot identify the issue, it is best to contact a professional plumber to conduct an emergency hot water repair service. Plumbers have the knowledge and expertise to diagnose and repair all types of hot water systems, including electric water heaters, solar hot water systems, and heat pumps. They are knowledgeable also about brands like Aquamax, Rinnai, Thermann, Rheem, Evoheat, Dux and more. They can also perform regular maintenance checks to prevent future hot water issues and ensure your system is working properly.

Contacting a professional for water heater repairs

In situations where hot water is not working, but cold water is, it is crucial to act quickly to prevent additional property damage. If there is a gas leak or water leak, turn off the gas supply switch or water supply valve and contact a licenced plumber immediately. If there is a rotten egg or sulphur-like odour coming from the hot water tap, turn off the gas supply valve and contact the gas company immediately.

Hot water issues are a common problem in Australian households, and there are many potential reasons why hot water may not be flowing. However, by understanding the common causes of hot water issues, troubleshooting your system, and contacting a professional plumber when needed, you can ensure that your hot water service is working correctly and providing warm water on demand.
