Gas Hot Water Systems Brisbane — Efficient and Reliable Hot Water Solutions

If your gas hot water system has stopped heating properly, takes too long to re-ignite, or keeps running cold halfway through a shower, it’s time to call an expert.
At CK Plumbing, we’ve spent more than 15 years installing, servicing, and repairing gas hot water systems across Holland Park, Mount Gravatt, Coorparoo, Tarragindi, Carina, and Brisbane’s Southside.
We’re licensed gas fitters and plumbers, offering same-day service for homeowners who value safety, efficiency, and comfort.

Why Choose a Gas Hot Water System

Gas systems remain one of the most energy-efficient and cost-effective ways to supply hot water in Brisbane homes.
They heat water quickly, recover faster than electric tanks, and keep working during power outages.

Benefits include:

  • Instant and consistent water temperature.
  • Lower running costs than electric models.
  • Environmentally friendly when paired with natural gas or LPG.
  • Ideal for large families or multiple bathrooms.
  • Compact designs for indoor or outdoor installation.


We install and service all major brands, including
Rinnai, Rheem, Dux, Bosch, and Vulcan.

Common Gas Hot Water Problems We Fix

  • Pilot light won’t ignite or stay lit.
  • Water temperature fluctuations.
  • Gas smell around unit or pipes.
  • Leaking pressure relief valves.
  • Corroded burners or blocked vents.
  • Low gas pressure or poor flame quality.


If your system shows any of these signs, shut it down and call us immediately.

Our technicians are licensed for both gas and plumbing repairs — a must under Queensland law. 

Our Gas Hot Water Repair Process

Step 1
Safety Inspection

We isolate gas and water supplies, check connections, and test for leaks using digital detectors.

Step 2
Fault Diagnosis

We test burners, thermocouples, and regulators to find the root cause of temperature or pressure issues.

Step 3
Repair or Component Replacement

Most faults can be fixed on the spot using genuine parts. If the tank or heat exchanger is beyond repair, we recommend a modern, efficient upgrade.

Step 4
Re-Test & Commission

Once repaired or replaced, we reignite the system, check for CO safety, and verify consistent temperature output.

Installation & Replacement Services

When replacing your gas system, CK Plumbing handles everything from supply and removal to commissioning and compliance.
We’ll help you choose the right option for your home:

  • Continuous flow (gas instant) — heats water only as you need it.
  • Storage tank models — great for steady demand and multiple taps.
  • LPG systems — perfect for homes without natural gas mains (see LPG Hot Water Systems).


All installations are carried out to Australian Standards AS/NZS 3500 and AS/NZS 5601, with gas compliance certificates provided upon completion.

Signs Your Gas System Needs Attention

  • Pilot light keeps going out.
  • Rumbling or hissing from the tank.
