Find out why you’re constantly running out of hot water. Issues like sediment buildup, faulty thermostats and undersized tanks cause the problem. Have a plumber inspect and repair your hot water system.
Having hot water on demand is a modern essential most households take for granted. But when the flow from the tap suddenly runs cold, it’s incredibly disruptive. Families are left unable to wash dishes, clothes or themselves. But when the flow from the tap suddenly runs cold, it’s incredibly disruptive. Identifying the cause is the first step to getting it working again. Having hot water on demand is a modern essential most households take for granted.
act fast, as prolonged issues can lead to damage.Knowing when to attempt DIY fixes versus calling in a professional prevents further problems. Basic maintenance also helps maximise the system’s lifespan.This guide will explore why hot water heaters stop working, troubleshooting techniques anyone can try, and when to call the experts.
There are a few typical culprits behind hot water running out unexpectedly:
The most obvious reason is high demand from multiple sources at once. For example, if several people are showering while the dishwasher and washing machine run a cycle. The average shower uses 20 litres of hot water per minute.
So it’s easy to overwhelm a system’s capacity.
Over time, sediment from hard water deposits can accumulate inside the tank. This mineral build-up insulates the water from the heating element. Flushing the water heater annually helps clear out these deposits.
Electric hot water systems rely on internal heating elements to warm the water. If one fails, the other may struggle to keep up with demand. Replacing a damaged element restores full function.
Gas systems depend on a pilot light and/or igniting valve to fire up the burner. If either malfunctions, the water won’t get hot. A plumber can diagnose and repair gas-related problems.
The dip tube channels cold water to the bottom of the tank. If it cracks, incoming water mixes with already-heated water at the top. This leads to lukewarm output.
If DIY troubleshooting tips don’t solve the issue, contact a professional. Continued problems risk damage to the water heater.
Inspecting key components of your hot water system can reveal issues affecting performance. Here are some basic checks any homeowner can perform:
This sacrificial metal rod inside the tank corrodes over time, protecting the tank itself. Replace it if heavily worn. Turn off power and water supply, then unscrew it from the top of the tank.
Electric water heaters have one or two heating elements that bolt onto the side of the tank. Check for cracks or excessive mineral deposits. Use a non-contact voltage tester to confirm they are receiving power.
This regulates water temperature. Turn the dial and check if the heating elements activate. If not, the thermostat may need replacing.
Gas systems rely on proper gas flow. Ensure valves are fully open and pilot lights ignite the burners. Call a professional for gas issues.
Sediment buildup reduces efficiency over time. Draining several gallons flushes out mineral deposits. Just be sure to shut off power first.
Noticing issues during inspection provides clues to the problem. Our team of plumbers can fully diagnose hot water system troubles and make expert repairs.
Hot water systems have a thermostat that controls the temperature of the water. Adjusting this is straightforward for both gas and electric models.
On an electric heater, the thermostat is usually behind a small metal door. Gas systems may have it attached to the outside of the tank. There should be a temperature gauge and dial.
Before adjusting, take note of the current temperature setting. Water heaters are typically preset to around 60°C. Higher increases energy costs and risks scalding.
Turn the dial clockwise to raise the temperature or counter-clockwise to lower it. Make small increments of around 5 degrees. Allow time for the water to heat up before testing.
After adjusting, run a hot tap for a few minutes then check the temperature. Repeat the process until it reaches the desired comfort level.
Aim for the lowest setting that provides sufficient hot water. Around 50-60°C is ideal in most homes. Also consider an insulation blanket to help maintain heat.
If unsure about making adjustments, contact a plumber for assistance ensuring optimal temperature and efficiency.
Key components inside the tank do eventually wear out and need replacement. This includes heating elements in electric water heaters and the anode rod.
These metal rods house the electrical resistance coils that heat the water. Hard water deposits and age slowly damage them. Signs it’s time to replace are:
Turn off power and water supply before removing the bad element. Make note of the wattage, diameter, and length to get the right replacement. Use pipe tape on the threads and don’t over-tighten.
This rod attracts corrosion instead of the tank. Proper anode rod maintenance extends the water heater’s lifespan.
Inspect it annually and replace when more than 6 inches of core wire is exposed. Inspect it annually and replace when more than 6 inches of core wire is exposed.

There are several ways to promote efficient usage and prevent wasted energy with your hot water system:
Lower the ThermostatSet the thermostat to 50-60°C. This provides sufficient hot water for most households without excess energy consumption.
Take Shorter ShowersSimply reducing shower length from 10 minutes to 5 minutes makes a big difference in hot water demand. Install a timer as a friendly reminder to keep it short.

While easy hot water fixes are suitable as temporary troubleshooting, it’s crucial to involve a professional plumber for certain issues:
Gas hot water systems contain flammable fuel and complex components best handled by licenced tradespeople. Don’t attempt DIY repairs on gas valves, pilot lights, or burners. Any sign of leaks or malfunction necessitates an urgent call to an expert.
If you’ve tried adjusting the thermostat, changing heating elements, and flushing sediment yet still have no hot water, a plumber’s diagnostic skills are needed. Continued use could damage the system.
Any visible corrosion or drips indicate a problem requiring the tanks, pipes and attachments be inspected. Catching leaks early prevents extensive water damage and mould risks.
Even properly maintained hot water units reach end of functional life. Have an expert assess systems over 10 years old even if operating normally. They can advise on repair, upgrading or replacement options.
Improper DIY repairs risk serious hazards plus voided warranties. Our licenced pros ensure workmanship adheres to all safety standards and manufacturer guidelines.

The sudden loss of hot water is hugely disruptive for households. The sudden loss of hot water is hugely disruptive for households. Adjusting the thermostat, replacing elements or anodes, and flushing sediment are DIY tasks many homeowners can handle. Installing insulation blanket also boosts efficiency.
However, it’s wise to call a licenced plumber for problems related to gas systems, leaks, or persistent issues. Preventative servicing maximises your hot water system’s lifespan. With proper care and repairs when needed, you can enjoy reliable flow for over a decade before replacement becomes necessary.
If you detect the smell of gas inside your home, evacuate all occupants immediately, leaving doors and windows open. Call your gas provider or emergency services using a neighbor’s phone once safely outside. Do not turn any electrical devices or appliances on or off.
