Types of Hot Water Systems
Understanding the type of hot water system you have installed is crucial for proper maintenance. There are generally three types of systems found in Australian homes:
- Storage tank systems: These systems utilise a large insulated storage tank to heat and store hot water. They can be powered by electricity, gas, or solar energy. Regular maintenance tasks for storage tank systems would include checking for leaks, inspecting the anode rod, and ensuring the pressure relief valve is functioning correctly.
- Instantaneous (tankless) systems: Also known as continuous flow systems, these heaters provide hot water on-demand by heating water as it passes through a unit. They can be powered by electricity or gas. Maintenance for tankless systems may involve cleaning the inlet filter, checking the heating elements, and periodic descaling.
- Heat pump systems: These systems extract heat from the air, ground, or water and transfer it to the water in the storage tank. Regular maintenance for heat pump systems includes checking for leaks, inspecting the compressor and refrigerant levels, and cleaning the condenser coil.
Hot Water System Maintenance Timelines
Each hot water system type requires unique maintenance tasks and schedules to ensure optimal performance:
- Storage tank systems: These systems generally require maintenance every two to three years. Tasks include checking for leaks, inspecting the anode rod, cleaning the tank, and testing the pressure relief valve.
- Instantaneous systems: Tankless systems should be serviced once a year to ensure optimal performance. Maintenance tasks include cleaning the inlet filter, checking the heating elements, and periodic descaling.
- Heat pump systems: Schedule regular maintenance every 12 to 24 months to maintain peak performance. Tasks to undertake include checking refrigerant levels, inspecting the compressor, and cleaning the condenser coil.
Essential Hot Water System Maintenance Tasks
Taking the time to perform the following tasks can help prolong the lifespan of your hot water system, increase energy efficiency, and prevent unexpected failures:
- Inspect for leaks: Routinely check your hot water system for leaks or signs of corrosion. Address any issues immediately to prevent further damage.
- Check and replace sacrificial anodes: The sacrificial anode rod in storage tank systems helps protect the tank from corrosion. Inspect the anode rod every two to three years, or according to the manufacturer’s guidelines, and replace it as needed.
- Flush the tank: Sediment can accumulate in storage tank systems over time, reducing the efficiency of the heater and causing damage in some cases. Periodically flush the tank to remove sediment and maintain optimal performance.
- Test the pressure relief valve: In storage tank systems, the pressure relief valve is a critical safety feature that releases excess pressure in the tank. Routinely test the valve to ensure proper function and replace it if necessary.
- Clean inlet filters: In tankless systems, sediment and debris can collect in the inlet filter, reducing efficiency and water flow. Regularly clean the filter to keep your system running smoothly.
- Descaling: Tankless systems may require periodic descaling to remove limescale and mineral deposits from the heating elements.
When to Call a Professional Plumber
While some basic maintenance tasks can be managed by homeowners, there are times when calling a professional plumber is necessary:
- Experiencing no hot water, inconsistent heating, or a noisy system: These issues can indicate a malfunction requiring professional diagnosis and repair.
- Replacing parts: Some tasks, like replacing sacrificial anodes, pressure relief valves, or heating elements, should be handled by a professional to ensure proper installation.
- Regular system servicing: Scheduling professional maintenance visits according to your hot water system’s requirements can help prevent emergencies and promote optimal performance.
