How To Maintain Your Hot Water System

May 18, 2023

A well-functioning hot water system is fundamental for comfortable living and a little care and regular maintenance can go a long way in keeping it running efficiently for years to come. For many Coffs Harbour residents, solar hot water systems are an excellent choice due to the region’s sunny climate. Let’s explore the steps you can take to keep your hot water systems in Coffs Harbour running at peak efficiency.

Regular Inspection

Regularly inspecting your hot water system is crucial for spotting potential issues before they become costly problems. Check for leaks, unusual noises or changes in water temperature. Look for any signs of rust or corrosion on the tank and pipes. A quick call to a local expert like North Coast Power & Water can help you address these issues promptly and professionally.

Flush The Tank Yearly

Sediment build-up in the tank can reduce your system’s efficiency and even cause damage. Flushing the tank at least once a year will remove any sediment and improve the overall performance. To do this, turn off the power supply, connect a hose to the drain valve and open it to let the water out. Once the tank is empty, briefly open the cold-water supply valve to help flush out any remaining sediment. Close the drain valve and refill the tank before turning the power back on.

Insulate The Tank

Insulating your hot water tank is a simple yet effective way to reduce heat loss and save on energy bills. Wrapping the tank with an insulating blanket can keep the water warm for longer, reducing the need for constant reheating. Insulating pipes can also prevent heat loss, ensuring hot water reaches your taps without losing its warmth. These small investments in insulation can result in significant energy savings, especially for solar hot water systems in Coffs Harbour.


The anode rod is a crucial component in preventing tank corrosion. Over time, the rod can wear down, making it less effective in protecting your tank. Replacing the anode rod every three to five years can extend the life of your hot water system. You can find the anode rod at the top of your tank, typically under a hexagonal head. Unscrew it with a wrench and replace it with a new one, ensuring it is the same type and size as the old rod.


The air intake filter in your hot water system plays a vital role in ensuring proper combustion, especially for gas-based systems. A clogged filter can lead to incomplete combustion and higher energy consumption. To maintain efficiency, clean or replace the air intake filter as needed. Check the manufacturer’s recommendations for filter replacement frequency and follow their guidelines.

By taking these simple steps to maintain your hot water system, you can enjoy energy savings and a longer system lifespan.
