How to Check if a Hot Water System Is Working? | Warragul Homeowner’s Essential Guide
If you’re stepping into your shower in Warragul only to be greeted with icy water, you’re not alone. Homeowners across Victoria, particularly in cooler regions like Gippsland and Warragul, often ask: How to check if a hot water system is working?

This guide provides a detailed yet accessible walkthrough of how to troubleshoot your hot water unit—from basic functionality checks to pinpointing signs of failure. Whether you’re dealing with an electric, gas, or solar hot water system, understanding the fundamentals can save you time, money, and a freezing surprise on a cold Warragul morning.
1. 🔎 Initial Visual Inspection: What You Can Check Right Away
Before you panic or call a local licensed plumber in Warragul, begin with a basic inspection. You don’t need to be a licensed technician to perform a quick health check of your unit.
✅ Power or Gas Supply
- Electric system: Check the circuit breaker on your switchboard. In older homes around Brandy Creek or Lillico, it’s not uncommon for a tripped breaker to be the culprit.
- Gas system: Ensure the gas valve is on. Also, check if other gas appliances in the house (like the stove) are functioning properly.
✅ Pilot Light (for Gas Units)
If you have a gas storage unit like a Rheem or Vulcan, locate the pilot light access panel and check if the flame is visible. No flame? That’s likely the issue.
✅ Water Leaks
Walk around the base of the unit. Look for pooling water or dripping—common in older systems especially during Warragul’s wetter months. Leaks could indicate a failed pressure relief valve or tank corrosion.
✅ Pressure Relief Valve
Lift the lever on the temperature-pressure relief (TPR) valve gently. A bit of water should discharge. If nothing happens—or water doesn’t stop flowing afterward—your valve may be faulty.
2. 🌡️ Run a Temperature Test at the Tap
Sometimes your hot water system is technically “working,” but not efficiently. Run hot water at the kitchen or bathroom tap and measure the temperature with a thermometer.
Ideal Water Temp:
- The Australian standard temperature is around 50–60°C at the tap.
- If it’s well below that—say in the 30s or low 40s—you might be dealing with a failing thermostat, sediment buildup, or partial heating failure.
This issue is particularly common in homes using electric storage systems in rural Warragul areas, such as Drouin South or Bona Vista, where mineral deposits may collect faster due to water hardness.
3. 🔌 For Electric Systems: Check the Element and Thermostat
Electric hot water systems typically use a heating element and thermostat. If the water isn’t hot or takes too long to heat:
- Listen for noise: A humming or crackling sound may indicate the element is struggling.
- Consider age: If your system is more than 8–10 years old, the element could be burnt out.
- Inspect with a multimeter: If you’re handy and safe around electronics, test the resistance of the thermostat and element. Or call a licensed electrician or licensed plumber in Warragul for diagnostics.
4. 🔥 For Gas Systems: Burner, Thermocouple, and Flue Inspection
If your gas system seems to be functioning but doesn’t deliver hot water:
- Thermocouple: This small sensor shuts off gas if the pilot light goes out. A faulty one can mimic a gas supply issue.
- Burner problems: If the burner isn’t igniting properly, it could be clogged with soot or dust—a common issue in older homes around Ellinbank or Nilma.
- Blocked flue: A blocked exhaust vent can also cause the system to shut down as a safety precaution.
5. 🏠 Solar Hot Water or Heat Pumps: Is It Just the Weather?
In eco-conscious areas of Warragul, solar hot water and heat pump systems are becoming increasingly popular. But they’re not immune to problems:
- Check booster function: Most systems come with an electric or gas booster for cloudy days. If you’ve had a cold spell (not rare in July), ensure the booster is working.
- Inspect solar panels: Look for dirt or shading on your collectors. A drop in efficiency could be weather-related or due to dirty panels.
6. 🔁 Consider System Cycling and Usage Patterns
How many people live in your household? Has usage increased?
Even a perfectly working system may not keep up with sudden demand surges—common when guests visit or routines shift. In Warragul homes with 4+ family members, this is a frequent cause of complaints. A system upgrade or installation of a larger storage tank may be in order.
7. 🛠️ When to Call a Plumber in Warragul
If you’ve run through all the above steps and your hot water is still inconsistent—or nonexistent—it’s time to call in the pros.
Licensed plumbers in Warragul are familiar with common issues in systems like Dux, Aquamax, or Bosch, which are commonly installed in homes throughout Gippsland.
Call a pro if:
- Pilot light won’t stay lit
- Water is leaking persistently
- You smell gas or hear hissing
- You suspect electrical damage
- The system is over 10 years old
8. 🚿 Prevention: Regular Maintenance Tips for Warragul Locals
Prevention is the cheapest solution in the long run. Hot water systems in Warragul are prone to wear and tear from weather shifts and mineral-heavy groundwater.
Schedule regular inspections:
- Every 12 months: Flush tank to remove sediment
- Every 2–3 years: Test and replace anode rod (especially in electric systems)
- Every 5 years: Inspect or replace the TPR valve
Local plumbers can provide a system health check tailored to Victorian compliance standards and your specific unit type.
9. ⚖️ Final Thoughts: Don’t Ignore the Warning Signs
So, how to check if a hot water system is working? Start by using your senses—look, listen, and feel. Evaluate temperature, pressure, and energy source. A minor issue now can snowball into a major failure or a costly replacement later.
Living in Warragul means dealing with distinct seasonal fluctuations. Your hot water system is vital—not just for comfort, but for health and safety. Stay proactive, and your system will serve you reliably for years to come.
