Gas Hot Water System Replacement Rinnai Broadbeach, Gold Coast
From Cold Shocks to Endless Hot Water: A Broadbeach Gas System Upgrade
Is there anything worse than stepping into the shower, expecting hot water, and getting an icy-cold surprise? Or trying to wash the dishes, only to find the tap runs cold? When your gas hot water system not working properly, it disrupts your entire day.
For a homeowner in Broadbeach, Gold Coast, this frustration was all too real. Their old, corroding gas system had reached the end of its life, failing to deliver reliable hot water. They called Fallon Solutions, and our team provided a complete gas hot water system replacement in Broadbeach, upgrading their home to an efficient, modern solution.
The Problem: A 15-Year-Old System on Its Last Legs
The problem wasn’t just a minor glitch; it was a system at the end of its serviceable life. The existing gas hot water unit was over 15 years old—well past the typical lifespan for many storage models.
The tell-tale signs were impossible to ignore:
- Significant Corrosion: Visible rust and corrosion on the outside of the tank are clear indicators that the unit’s integrity is compromised. This is often the first step towards a major leak and complete system failure.
- Unreliable Hot Water: The system was failing to deliver hot water consistently. This could mean lukewarm water, hot water that ran out almost immediately, or no hot water at all.
- An Ageing Gas Regulator: The customer was also (rightly) concerned about the old gas regulator. This component is vital for safety, controlling the gas pressure delivered to the appliance. An old regulator can fail, leading to poor performance or a dangerous situation.
This wasn’t just a simple repair job; it was time for an old hot water system replacement to ensure the home’s safety and comfort.

The Solution: A New Rinnai B16 Continuous Flow System
After we provided a clear, upfront quote and walked the homeowner through the process, our licensed hot water plumber in Broadbeach returned to complete the installation. A gas installation requires precision and a strict adherence to safety protocols.
1. Safe Decommissioning
First, our licensed gas fitter made the site safe. This involved isolating both the water and the main gas supply. The old, corroded tank and its components were then carefully disconnected, drained, and removed from the property for disposal.
2. Installing the New Rinnai B16
We supplied and installed a brand new Rinnai B16 continuous flow gas hot water system. This is a fantastic upgrade. Unlike old storage tanks that constantly heat a large volume of water (even when you’re not using it), a continuous flow system heats water instantly as you need it.
3. Full Safety & Compliance Upgrade
A replacement isn’t just about the main unit. To meet current Australian Standards and ensure long-term safety, we also:
- Installed a new valve kit to ensure the new system operates safely and efficiently.
- Installed a new gas regulator to guarantee a stable, correct gas pressure from the main line to the new Rinnai.
- Reconfigured pipework as needed to create a neat, professional, and leak-free connection to the new, compact unit.
4. Critical Gas Safety Testing
This is the most important step in any gas appliance installation. Our licensed gas fitter performed a full gas tightness test. This involves pressurising the entire gas line (to 2.75kPa in this case) and using a special gauge (a manometer) to confirm there are absolutely zero gas leaks, no matter how small. The system passed perfectly.
We then ‘commissioned’ the unit—firing it up, testing the water temperature at the taps, and ensuring perfect, consistent operation. Finally, we handled all the paperwork, submitting the necessary council forms and issuing the Gas Compliance Certificate to the homeowner.
The Benefits for the Homeowner
This gas hot water system replacement in Broadbeach didn’t just fix a problem; it provided a major lifestyle and home upgrade. The homeowner now enjoys:
- Endless Hot Water: The Rinnai gas hot water system (B16) provides instant, continuous hot water. No more running out mid-shower, even if you have guests!
- Improved Energy Efficiency: By only heating water on demand, this system is far more energy-efficient than the old 15-year-old storage tank. This translates directly to lower energy bills.
- Total Safety and Compliance: With a new, certified installation, a new gas regulator, and a passed tightness test, the homeowner has complete peace of mind knowing their system is safe.
- Long-Term Reliability: A new Rinnai, installed correctly by a professional, is a long-term investment that will provide reliable service for many years.
