Expert Diagnostics for Continuous Flow Systems
Properties in Cremorne vary from Federation-era homes to mid-century walk-ups and modern harbourside apartments. Many of these dwellings have switched to gas instant hot water systems like the Rinnai Infinity or Rheem Metro to save space. When these units fail, it is usually due to a specific component such as a flow sensor, ignition lead, or a blown fuse on the PC board. We offer a standard diagnostic service starting from $195 to identify the exact fault. Our team carries specialized testing equipment designed for continuous flow electronics, ensuring we don't just guess which part is broken. We focus on fixing the unit on-site to restore your hot water immediately.
Solving Ignition and Pressure Issues in 2090
A common issue in Cremorne’s older apartment blocks is fluctuating water pressure, which can cause an instant gas hot water system to fail to ignite or shut off mid-shower. These systems require a specific minimum flow rate to activate the burners. We often find that older galvanized piping or blocked inlet filters are the culprit rather than the heater itself. Our technicians examine the entire setup, including the gas pressure and water flow, to ensure your Bosch or Dux system operates at peak efficiency. If your unit is clicking but not staying lit, it often points to a faulty flame rod or solenoid valve, both of which are routine repairs for our team.
Electric Instant System Specialist Repairs
While gas is prevalent along the Lower North Shore, many Cremorne renovations now utilize 3-phase electric instant hot water units, such as those from Stiebel Eltron. These are high-performance machines that require a technician who understands both the plumbing and the electrical load requirements. A loss of hot water in an electric instant system is frequently linked to a tripped thermal cut-out or a scaled-up heating element. Because these units are often tucked away in internal cupboards or under sinks, they require a careful hand to service without damaging surrounding cabinetry. We provide comprehensive repair services for these high-end electric models.
Brand Specific Solutions for Heritage Homes
Older Federation terraces near Cremorne Point often have bespoke hot water configurations. If you have an older external gas unit that hasn't been serviced in years, it may be suffering from dust buildup in the burners or a cracked heat exchanger. We work with all major brands, including AquaMax and Vulcan, sourcing genuine manufacturer parts to ensure the repair lasts. We don't believe in band-aid fixes; we look for the root cause, whether it's a faulty tempering valve or a degrading diaphragm. Our goal is to ensure your system meets current NSW plumbing standards while providing the 'endless' hot water these units are famous for.

Frequently asked questions
What should I do if my instant system shows an error code?
If your Rinnai Infinity or Rheem Continuous Flow unit displays a numerical code on the digital monitor, it indicates a specific component failure. Common codes for Cremorne properties relate to ignition failure or water flow sensor blockages. We recommend turning the power point off at the wall for sixty seconds to attempt a reset. If the code persists, do not attempt to open the cabinet yourself as these are complex gas appliances. Call 1300 INFINITY for a licensed technician to attend.
Why is my apartment's instant system not heating?
In many Cremorne apartments, instant systems are installed in tight recesses or cupboards on balconies. If you are experiencing a 'no hot water' situation, check that the isolation valve hasn't been bumped and that your gas supply is active. If the unit makes a clicking sound but doesn't fire, the solenoid or ignition pack may have failed. Our technicians carry these common parts for major brands to ensure we can complete the repair on the first visit.
Is it better to repair or replace an old instant unit?
Continuous flow systems generally last 12 to 15 years. If your unit is over a decade old and requires a major repair, like a new heat exchanger which can be costly, we may suggest a replacement. However, if it is a minor issue like a faulty sensor, thermocouple, or diaphragm, our $195 repair assessment often leads to a quick fix that extends the unit's life significantly, making repair the more economical choice for many residents.
Why is my shower water temperature fluctuating?
Fluctuating water temperatures are often caused by a 'cold water sandwich' which occurs when the flow rate is too low to keep the burners ignited. In some older Cremorne homes, debris in the inlet filter can restrict flow. We also check the tempering valve, which is a mandatory safety device that mixes hot and cold water. If this valve is faulty, you will get lukewarm water regardless of how high the heater is set.
