Essential Tips For Gas Hot Water System Maintenance

Maintaining your gas hot water system is crucial for ensuring its efficiency, longevity, and safety. Regular maintenance not only helps prevent unexpected breakdowns but also ensures that your system operates at optimal performance, providing you with a reliable supply of hot water.

In this article, we will explore essential tips for maintaining your gas hot water system. By following these guidelines and scheduling regular professional servicing, you can extend the lifespan of your system and enjoy peace of mind knowing that your hot water supply is secure and efficient.

Gas Hot Water Systems 101

Before we explore the various gas hot water system maintenance tips, let’s get the complete lowdown on all things gas hot water systems first.

Most Australian homes will have one of three main types of gas-powered hot water heater. It’ll either be:

• a storage hot water system
• a tankless continuous flow system
• a gas-boosted, solar-powered hot water system

The latter relies on gas to get through the days or seasons when the energy of the sun might not be at its most powerful.

How Does Each Work?

Gas-powered storage tank systems work by using a gas burner to heat water stored in a tank. The burner, located beneath the tank, heats the water using gas. The thermostat regulates the water temperature, ensuring it remains within a safe and efficient range. The gas supply is connected to the burner, providing the fuel necessary for heating the water. The heated water is then supplied to your hot tap. With hot water tanks, there is the possibility

Continuous flow systems heat water only when needed. When you turn on the hot water tap, the system ignites a gas burner which heats water as it flows through a heat exchanger. This provides an endless supply of hot water without relying on a storage tank system.

The Importance of Professional Inspections

Regular professional inspections are crucial for maintaining the efficiency and safety of your gas instant hot water system. Licensed professionals can check for any issues, perform necessary adjustments, and ensure all components are functioning correctly, helping to prevent potential problems before they arise.

1. Conduct Regular Visual Inspections

Regular visual inspections of your gas hot water system are essential for maintaining its longevity and efficiency. Check for visible signs of wear, such as

• leaks
• rust
• corrosion around the tank and pipes

These can lead to bigger issues if not addressed.

Make sure the area around the system is clear of debris and flammable materials to promote better air circulation and reduce fire hazards. Inspect the burner flame, which should be blue; a yellow or orange flame indicates incomplete combustion and needs professional attention. Additionally, check the pilot light to ensure it is functioning correctly, as it plays a crucial role in igniting the burner.

2. Check the Pressure Relief Valve

Regularly check the temperature and pressure relief valve. This is a critical safety component of your gas hot water system. Pressure relief valves stop the excessive build-up of pressure by releasing water when necessary.

To inspect it, locate the valve on the side or top of the tank, and place a bucket under the discharge pipe. Lift the valve lever; you should hear a rush of air or see water flow into the bucket. If nothing happens or the valve leaks continuously, it may need replacing by a professional.

Regular servicing of the pressure relief valve ensures the safe operation of your hot water system, and any malfunctions should be promptly addressed by a licensed professional to avoid potential hazards.

3. Flush the Tank

Flushing the tank of your gas hot water system removes sediment build-up, this will keep your system functioning properly and efficiently.

Over time, minerals and debris settle at the bottom of your tank. This can reduce heating efficiency and cause potential damage. To flush the tank, do the following:

• Turn off the gas supply and water heater.
• Connect a hose to the drain valve at the tank’s bottom, and direct the other end to a drainage area.
• Open the valve and let the water flow until clear. This will indicate the tank is free of sediment.
• Close the valve, disconnect the hose, and refill the tank before turning the gas back on.

Annual flushing helps maintain performance, extend system lifespan, prevent costly repairs, and ensure a steady hot water supply. Having a professional perform this task ensures safety and accuracy.

4. Monitor the Thermostat

Regularly monitoring the thermostat in your gas hot water system ensures optimal performance and energy efficiency.

Periodically check the settings to ensure they are within the recommended range of 60°C to 65°C. Setting the temperature too high increases scalding risks and energy consumption, while too low a setting can lead to insufficient hot water and potential bacterial growth. If you notice temperature fluctuations or suspect a malfunction, the thermostat may need professional adjustment or replacement. A faulty thermostat can cause inefficiency and higher energy costs.

Regular professional servicing helps identify and address issues. It ensures your gas water heater works safely and efficiently and adds to its overall longevity.

5. Replace The Sacrificial Anode

The sacrificial anode, a crucial metal rod constructed of magnesium or aluminium, protects your gas hot water system from corrosion.

This metal rod attracts corrosive elements in the water, sacrificing itself to prevent the tank from rusting. Maintaining the sacrificial anode regularly is essential to ensure it continues to protect your system. Inspect the anode every 1-2 years and replace it when it’s significantly corroded.

This simple maintenance step extends the lifespan of your hot water system, preventing costly repairs and ensuring efficient operation. Always consult a professional to perform this task safely and correctly.
