HOT WATER SYSTEM SERVICES
HOT WATER REPAIRS
Not every hot water problem means the entire system needs to be replaced. Luke can assess faults such as inconsistent temperatures, leaking valves or connections, ignition problems, unusual noises and hot water running out too quickly.
Where repair is practical, the aim is to restore safe, reliable operation and extend the life of the system.
HOT WATER SYSTEM REPLACEMENT
If your existing system is leaking, badly corroded, frequently breaking down or no longer meeting your household’s needs, replacement may be the better long-term option.
Luke can remove the old unit, explain the available choices and install a suitable replacement for your property and household requirements.
NEW HOT WATER INSTALLATIONS
Building, renovating or installing hot water in a new area of your property?
Onboard Plumbing & Gas can assist with new hot water system installations and the associated plumbing and gas connections required for a safe, compliant result.
GAS, ELECTRIC AND CONTINUOUS-FLOW SYSTEMS
Onboard Plumbing & Gas works with a range of hot water systems, including gas, electric, storage and continuous-flow units.
The right option will depend on your household’s hot water use, available services, installation space and budget. Luke can assess the property and provide honest advice about the most suitable solution.
PROFESSIONAL HOT WATER REPAIRS
Not every hot water problem means the entire system needs to be replaced. Depending on the fault and condition of the unit, a professional repair may restore reliable operation and extend the life of the system.
Luke can assess issues involving valves, plumbing connections, ignition systems, water flow, pressure, thermostats and other components affecting performance.
Once the system has been inspected, he will explain what has been found and provide clear advice about whether repair or replacement is the most practical option.
HOT WATER SYSTEM REPLACEMENT AND UPGRADES
If your existing hot water system is leaking, badly corroded, frequently breaking down or no longer meeting your household’s needs, replacement may be the most practical long-term solution.
Luke can help you consider factors such as:
✔ Household size and hot water use
✔ Gas or electricity availability
✔ Storage or continuous-flow options
✔ Installation space and location
✔ System capacity
✔ Existing plumbing and connections
Once the property and current system have been assessed, Luke will explain the available options and recommend a suitable replacement without unnecessary pressure.
WHAT CAN AFFECT YOUR HOT WATER SYSTEM?
THERMOSTAT OR HEATING FAULTS
A faulty thermostat or heating component can cause inconsistent temperatures, slow heating or a complete loss of hot water.
LEAKING VALVES OR CONNECTIONS
Worn valves, loose fittings or damaged pipe connections may allow water to leak around the unit and affect its performance.
IGNITION OR GAS SUPPLY ISSUES
Gas hot water systems may fail to heat properly when there is a problem with the ignition system, pilot light, gas supply or related components.
SEDIMENT, RUST OR CORROSION
Sediment and corrosion can develop over time, contributing to unusual noises, discoloured water, reduced efficiency or deterioration of the system.
AGEING OR WORN COMPONENTS
As components wear, a hot water system may require more frequent repairs, provide less reliable heating or no longer meet the household’s needs.
REPAIR OR REPLACE YOUR HOT WATER SYSTEM?
Not every hot water fault means the system needs to be replaced. In some cases, an isolated repair may restore reliable operation and extend the life of the unit.
Repair may be suitable when:
-
The fault is isolated and repairable
-
The system is otherwise in good condition
-
Replacement parts are available
-
The unit still meets your household’s needs
Replacement may be more practical when the tank is leaking or badly corroded, repairs are becoming frequent or the system no longer provides enough hot water.
Luke can inspect the unit and provide honest advice about the most practical option.

HOT WATER SYSTEM FAQs
WHY HAVE I SUDDENLY LOST HOT WATER?
A loss of hot water may be caused by a failed heating component, thermostat fault, ignition problem, interrupted gas or electricity supply, water-flow issue or another system fault. A professional inspection can identify the cause.
WHY DOES MY HOT WATER RUN OUT SO QUICKLY?
The system may be too small for the household, no longer heating effectively or affected by a thermostat or internal component fault. Your household’s hot water requirements may also have increased.
CAN A LEAKING HOT WATER SYSTEM BE REPAIRED?
It depends on where the leak is coming from. A leaking valve, pipe or connection may be repairable, while a leaking or badly corroded storage tank will often need to be replaced.
HOW DO I KNOW WHETHER TO REPAIR OR REPLACE MY SYSTEM?
The decision depends on the system’s condition, the type and cost of the fault, its repair history and whether it still meets your household’s needs. Luke can assess the unit and explain the most practical option.
DO YOU INSTALL GAS HOT WATER SYSTEMS?
Yes. Onboard Plumbing & Gas can install, replace and service gas hot water systems and complete the associated licensed gas-fitting work.
DO YOU WORK WITH ELECTRIC HOT WATER SYSTEMS?
Yes. Onboard Plumbing & Gas can complete the plumbing work required for electric hot water repairs, replacements and installations. A licensed electrician may also be required for electrical work.
WHAT IS A CONTINUOUS-FLOW HOT WATER SYSTEM?
A continuous-flow or instantaneous system heats water when it is needed rather than storing hot water in a tank. The correct unit must be selected for the property and expected household demand.
WHAT SHOULD I DO IF I SMELL GAS NEAR MY HOT WATER SYSTEM?
Avoid flames, smoking and electrical switches. Move away from the affected area and contact a licensed gas fitter from a safe location. Call emergency services where there is an immediate danger.
