Gas Hot Water Repairs & Replacement across Sydney

We service, repair, replace and install gas hot water units for homes on natural gas and LPG. Repair work takes in pilot and ignition faults, thermocouple and gas valve failures, leaking cylinders and tired TPR or tempering valves, and emergency callouts are part of what we do. Servicing includes anode checks, burner cleaning and a TPR test, while replacements and new installs cover both storage cylinders and continuous flow units along with any flue or gas line changes required.

Arriving home from a trip to find the hot water system dead is a common emergency call, and we attend these as a priority, usually the same day. Often the pilot has simply gone out while the house was empty, but if relighting it according to the unit instructions does not hold, a licensed gasfitter needs to look at the thermocouple or gas valve. Ring us with the unit type and what you have tried so far.

Our service area takes in the local district and the suburbs around it, with a wider reach for new hot water installations and bigger projects. If you are on the fringe, just ask and we will let you know on the spot.

Ask whether the quote assumes a like-for-like swap or a change of type, because this is where prices diverge most. Moving from storage to instantaneous hot water often means a larger gas line and a different flue, and those items should be clearly stated rather than discovered later. A free written quote after an on-site look is the only reliable way to settle this.

The pilot jet on a hot water system is tiny, and dust, rust flakes or spider webs can partially block it over time. A starved pilot burns small and unstable, so it struggles to heat the thermocouple properly and drops out. Cleaning the jet and checking the flame is a job for a gasfitter rather than something to attempt yourself.

Every gasfitter on our team holds a current gasfitting licence, and the business carries public liability insurance. Gas work in Australia must by law be carried out by a licensed gasfitter, so you should never accept anything less. When the job is finished you receive a compliance certificate to keep with your records.

A storage tank is lined to resist corrosion and protected by a sacrificial anode, but that protection does not last forever. When the anode is spent and the lining fails, rust works through the steel and the tank leaks from the body rather than from a fitting, and no repair will seal it. At that point we recommend replacement rather than putting money into a cylinder on its way out.

The quickest installs are those where the new hot water system matches the old one in type, size and position. Those are usually complete in a few hours including testing. Add a relocation, a flue upgrade, a new gas line or a tempering valve and the job grows, which is why the quote carries a time estimate along with the cost.

If you have just moved into a home and know nothing about the hot water unit, a service is the quickest way to learn its condition. The gasfitter tests gas pressure at the regulator, cleans the burner and checks the flame, tests the ignition or thermocouple, checks the flue and draught, and operates the TPR valve. The tempering valve is set to 50 degrees Celsius, the anode or heat exchanger is checked depending on the unit type, and the written report tells you what is sound and what to budget for down the track.

Store the user manual with your invoice and compliance certificate, because the manufacturer’s warranty conditions are printed in it and they usually include servicing requirements. Follow those, use a licensed gasfitter for any work, and the unit stays covered for its full term. Our workmanship guarantee on the installation or repair requires nothing from you beyond keeping the invoice.

Picture a continuous flow unit that will not fire at one tap but works at another. The unit needs a minimum water flow to switch on, so a water-saving tap or a partly closed mixer may not draw enough to trigger it. If every tap is cold, the cause is more likely gas supply, ignition or a controller fault, which your gasfitter can diagnose.

There is no single better option, only the option that matches your home. A continuous flow unit is compact, mounts on an external wall and delivers hot water for as long as the tap is open, but it needs adequate gas and water pressure and can take a moment to come up to temperature on short draws. A storage tank is simpler and handles bursts of simultaneous demand without fuss, at the cost of standing heat losses and the chance of running cold after heavy use. We assess both against your situation and give you a straight recommendation.
