What to do when your hot water system breaks down

Introduction to Hot Water Systems

In Australia, hot water systems are crucial for daily living, supplying necessary hot water for various household tasks. They supply hot water for bathing, dishwashing, laundry, and various household activities. Common types of hot water systems used in homes today include:

• Storage tank systems - Insulated containers that keep water warm, often referred to as hot water heaters. Gas or electric elements are responsible for heating the water. Storage tank systems come in various models, including traditional gas, efficient electric water, and the eco-friendly solar versions.
• There are different types of water heating solutions, such as tankless models, which heat water directly as it flows through the system, negating the need for a storage tank. Tankless systems, with their continuous flow of water, can utilise natural gas or electricity to heat water on demand.

These systems, from gas to solar models, have their own advantages and drawbacks in terms of energy efficiency, cost, and maintenance requirements. Storage hot water heaters are cost-effective at first, yet they may incur higher maintenance costs with frequent use. While the initial cost is higher for tankless systems, their superior water heating efficiency can lead to long-term savings.

Like any household system, hot water systems can occasionally break down or stop working properly. Knowing how to inspect and rectify issues can ensure a swift and secure restoration of your hot water supply. Routine maintenance, including regular system check-ups, is essential for longevity.

This article provides a detailed guide for homeowners to troubleshoot common hot water system issues. It includes DIY fixes for minor issues and guidelines to maintain optimal hot water function. Understanding the factors that can damage your system and taking preventative measures goes a long way toward avoiding costly breakdowns and water damage.

Checking Power and Water Supply

Begin by confirming that power and water are reaching the system, which can rule out a potential hot water system leak. Here’s how to safely inspect your system when there’s no hot water:

1. Turn off power at the main circuit breaker before doing any checks. This ensures you don’t get electrocuted if touching electrical parts.
2. Check that the power supply cord or wires are still intact, attached, and not damaged. Make sure circuit breakers, GFCIs, or fuses are working properly.
3. For your gas hot water system, locate the gas valve and ensure it is turned off. Ensure the gas lines are undamaged and the gas supply is on, as opposed to being turned off gas unintentionally.
4. Verify that water supply lines and valves are open, This step verifies there are no issues with low water pressure. Ensure the cold water inlet and hot water tap pipes leading to the tank are intact and free of leaks or blockages.
5. Conduct a visual inspection of your hot water tank to identify any external rust or potential damage. Significant leaks from pipes or the tank could cause severe hot water service disruptions.

Turn power and gas back on once you’ve completed the initial checks. Should power and water connections be in order yet you find there’s no hot water, the complication lies within the heating mechanism or its components. Professional help may be necessary to fix a broken hot water system.

Common Hot Water System Issues

Hot water systems can experience several common issues:

• Faulty thermostat - The thermostat maintains the desired water temperature pressure balance within the hot water tank. If it is not working properly, you may get water that is too hot or too cold.
• Heating element failure - Electric hot water systems, which include one or two heating elements to heat the water, are an integral part of ensuring you have access to warm showers and clean clothes. Failure of these elements can result in a complete lack of hot water or significantly reduced availability.
• Pilot light outage - Gas water systems depend on a pilot light to kindle the burner efficiently. If this goes out, the water will not heat. Should you experience a lack hot water, one step is to see if the pilot light has gone out and may need relighting.
• Pressure relief valve leakage - Hot water tanks are equipped with a pressure relief valve to manage excess pressure. A valve that persistently drips or leaks likely needs replacement.
• Sediment buildup - Over time, scale and sediment can coat the inside of the tank, reducing heating efficiency. Flushing the tank yearly can help prevent major buildup.
• Anode rod corrosion - The metal anode rod in a water heater attracts corrosion instead of the tank. When it corrodes excessively it should be replaced to protect the tank.

Regular maintenance, such as annual water heater flushing and replacing the anode rod every five years, can prevent many problems. If issues arise, start by checking the power supply, thermostat and heating elements, pilot light, and pressure relief valve. Don’t hesitate to call your professional plumber when faced with more intricate hot water system challenges.

DIY Troubleshooting and Solutions

There are a few basic troubleshooting steps and solutions homeowners can try themselves on their hot water systems before calling a professional:

1. Check the power supply - Reset any tripped circuit breakers or replace blown fuses. Make sure the switch on your electric water heater is turned on.
2. Inspect the thermostat - Set it to the highest temperature and see if the water heats after 20-30 minutes. If not, the thermostat may need replacing.
3. Check the heating element(s) - Use a multimeter to test elements for continuity. Replace any defective ones.
4. Relight the pilot light of your faulty hot water system - Refer to the user manual for the proper lighting procedure. Make sure gas supply is on.
5. Inspect the pressure relief valve - Open and close it manually using a rag to check for defects. Replace if necessary.
6. Drain and flush the tank - To combat sediment buildup that reduces heating efficiency, you’ll need to periodically drain 1-2 gallons from the tank.

Always disconnect power and shut off gas before starting repairs, and allow components to cool. Refer to your owner’s manual if unsure of any procedure. If issues remain despite basic troubleshooting, you lack the necessary skills, or if a complete system replacement is essential, seek professional repair services.

When Professional Help is Needed

There are certain situations when it’s best to call a professional plumber to service your hot water system:

• If you detect a gas smell from your hot water system, This indicates a potentially dangerous gas leak, so cut off the gas supply and call a plumber immediately.
• You notice significant leaks from the tank, pipes, or fittings. Address significant leaks promptly with professional repairs to forestall water damage.
• Despite attempting troubleshooting and DIY repairs, the issues continue. A professional can fully diagnose and repair your hot water system issues.
• The system is very old and replacement parts are no longer available. A full new hot water system replacement may be required.
• The hot water is scalding hot even on the lowest temperature setting. The thermostat likely needs adjustment or replacement.
• Your tank shows excessive sediment buildup or corrosion. Periodic flushing and anode replacement may be needed.

Plumbers have the expertise to accurately assess top water heater issues and repair them properly for optimal performance and longevity. They can also determine if full replacement is the most cost-effective option. Professional installation ensures new systems are correctly sized and meet safety standards.

Selecting the Appropriate Hot Water System

When your existing hot water system breaks down repeatedly or reaches the end of its lifespan, an important decision is choosing between repairing it or investing in a new system. Consider the following factors when comes to making an informed decision:

• Age and lifespan - Storage tanks typically last 8-12 years and older systems may require more frequent repairs and parts.
• Energy efficiency - Newer systems like heat pumps and tankless models are more energy efficient, saving on energy bills.
• Consider hot water needs; tankless systems provide instant hot water on demand. For larger homes, various storage tank types offer larger capacities for hot water.
