Introduction to Hot Water System Servicing

Regular servicing is essential for efficient and safe operation of Penrith water heaters. Servicing your hot water heater as recommended can improve its lifespan and performance. It also prevents issues like corrosion, scaling, and relief valve faults.

This article covers the advantages of water system servicing, required frequency, common issue prevention, and maintenance indicators.

Understanding Different Types of Hot Water Systems

There are several common types of hot water systems used in homes:

Solar Hot Water

Solar PV systems, using thermal collectors and a storage tank, efficiently heat your water with solar energy. While they use minimal electricity, replacing anode rods and checking insulation regularly is crucial to prevent corrosion.

Electric Storage Tank

Electric storage tanks heat water using an electrical element within an insulated tank. They require anode rod and heating element replacement and insulation checks during servicing.


Gas tankless systems with a tempering valve deliver on-demand hot water, bypassing the need for a storage tank. Gas tankless models need their pilot light and thermocouple checked. Electric tankless models require Scale prevention measures.

Gas Storage Tank

Gas hot water heaters with storage tanks use a gas burner and flue system to heat the water. The pilot light, thermocouple, and flue valve all require safety checks during servicing.

Heat Pump

Heat pumps, typically with a five-year lifespan for components, employ compressor heat exchange and fans to warm water. Heat pumps need their air filters and fans checked and cleaned during servicing.

The Role of Regular Maintenance

Maintaining your hot water system regularly is crucial for its efficiency and preventing problems. Annual inspections ensure that components such as heating elements, anode rods, insulation, and valves remain in good working order.

Lack of maintenance can lead to various hot water heater problems:

  • Corrosion and rust from age, heat cycles and water chemistry damages components
  • Scale buildup reduces heating efficiency and water flow
  • Faulty valves can cause dangerous water temperature spikes and pressure issues

In hard water areas, scale deposits form rapidly if not prevented. Safety mechanisms also have a reduced lifespan when your regular maintenance is neglected. A neglected hot water system will generally fail earlier and run less efficiently.

An annual dedicated hot water system service can extend your system’s lifespan by an average of 3-5 years. Technicians thoroughly inspect all components, test valves and safety switches, replace anodes and flush scale to get my hot water system running optimally during routine maintenance.

Improving Efficiency and Lifespan

Regular servicing improves the efficiency of your hot water unit and extends its lifespan. During servicing of your water heater, technicians perform checks and replacements that optimise performance.

Regular servicing, which entails replacing the anode rod every five years, can prolong the system’s life to 15-20 years, particularly for solar models. Actions to do hot water systems checks include reviewing insulation, heating elements, pilot lights, and other components to prevent efficiency-reducing issues.

Servicing also involves removing scale buildup from the pipes and storage tanks.

With comprehensive maintenance, a hot water system can typically last an extra 3-5 years. Operational costs are reduced due to the unit running at peak efficiency. A small annual servicing fee can prevent costly component failures in the future.

During maintenance appointments, our technicians meticulously assess the condition of your gas hot water systems and heaters. We also provide personalised guidance on service frequency tailored to Penrith’s water conditions. Contact our team today to keep your water unit and hot water system efficient for the years ahead.

Preventing Costly Repairs

Consistent servicing ensures hot water availability and helps prevent severe damage that could lead to costly repairs. Servicing identifies minor issues before they escalate into critical failures, which prompts homeowners to wonder how often they should service their system.

Replacing an anode rod every five years for $150 can prevent a $2000 replacement of the entire water tank due to corrosion. Checking heating elements, wiring, flues, valves, and insulation ensures your tank system functions efficiently and safely.

During maintenance, technicians test components such as temperature pressure relief and tempering valves. A $250 dual relief valve replacement prevents burst pipes and water damage averaging $5000 in repairs.

Faulty relief valves can lead to venting hot water pressure spikes that exceed safe limits and potentially damage your pipes and fittings.

In total, the relatively minor yearly cost of preventative servicing saves thousands in emergency repairs from ageing components and undetected issues. We help clients optimise servicing schedules to maximise efficiency and lifespan while reducing unnecessary costs and failures.

Ensuring Safe Operation

Regular maintenance every six months ensures the safe operation of your gas hot water system, protecting your home over time. Contact your local experts if you’re facing issues like gas leaks, electric shorts, excess water pressure, faulty relief valves, or overflow leaks to ensure safety.

During maintenance, technicians conduct thorough safety inspections of gas and all other water heater components. Gas systems are checked for leaks around fittings and pipes using leak detection methods. Electrical systems are inspected for damage, corrosion and faulty connections which may cause shorts or shocks.

Trained professionals test relief valves to confirm they operate within safe pressure limits. Faulty valves can allow spikes over 1000kPa, risking pipe bursts and dangerous leaks. Maintaining reliefs valves helps prevent water damage and flooding.

Preventative servicing assures the safety of your hot water system for your family and home. Minor maintenance helps identify issues before they escalate, allowing intervention before potential threats like electric shock or gas leakage occur.

Key Components to Service

Sacrificial Anode Rod

The anode rod is a metal rod that corrodes to prevent corrosion damage to the inner tank. They require replacement every 3-5 years. Regular servicing includes anode rod replacement to prevent early tank failure.

Relief Valve

Temperature pressure and relief valves release excess heat and water pressure to prevent dangerous overheating or pipe bursts. They should be tested yearly to ensure proper pressure thresholds.

Pipe and Tank Insulation

Insulation around hot water pipes and tanks prevents heat loss and energy waste. Regular servicing checks insulation levels, replacing degraded insulation as needed.

Recommended Service Intervals

Solar Hot Water Systems

Solar hot water systems require annual servicing for optimal performance. This involves checking and replacing the sacrificial anode rod, testing the relief valve and inspecting the solar water collector panels and insulation.

Electric and Gas Storage Tank Systems

Your electric hot water system and gas storage tank hot water systems need servicing every 3-5 years. This involves replacing heating elements and anode rods as required, testing relief valves and insulation, and inspecting flues, fittings and pipework.

Tankless/Instantaneous Systems

It’s crucial that tankless systems are inspected annually for scale removal and checks on pilot lights, heating elements and flow sensors.

Heat Pump Systems

Regular hot water systems, including heat pump models, should be serviced every 2 years. This involves cleaning air filters, testing heating elements and replacing any worn parts as required.

We advise all Penrith hot water system owners to undergo a free annual assessment for determining the best maintenance schedule. Our technicians provide quotes based on your system type, age, usage levels and water quality.

Signs Your System Needs Servicing

Strange Noises

Banging, whistling, or gurgling sounds from your water system may indicate issues that require expert attention. Have a technician check when i get my hot water system serviced if you detect any strange sounds right away.


Leaking from the tank, valves or fittings may signal corrosion, cracks or loose joints needing repair. Even minor leaks should be addressed promptly.

Rust Accumulation

Check around the base of your system periodically for rust stains or corrosion that may require hot water repairs.

Pressure Relief Drips

Continuous dripping from the pressure relief valve may indicate hot water system needs for valve replacement to maintain safe water pressures.

Reduced Hot Water

Lower hot water pressure, capacity or heating performance indicates servicing is needed to remove scale deposits and restore flow.
