Hot Water System Installation & Upgrades

- On-Demand Efficiency
- Space-Saving Technology
Tired of being the last person in the shower only to find the water has gone cold? At Plumbnet, we specialise in the installation and maintenance of high-performance Instantaneous (Continuous Flow) Hot Water Systems. Unlike traditional bulky tanks that heat and reheat the same water all day, an instant system only heats water when you turn on the tap.
With over 10 years of industry experience across Sydney, we understand the local plumbing infrastructure and the specific pressure requirements needed for a seamless “instant” experience. Whether you are upgrading from an old electric cylinder or installing a new gas line, our licensed team ensures your system is calibrated for maximum thermal performance.

Our Expert Instant Hot Water Services
Gas Continuous Flow Installation
We are fully licensed Gasfitters. We handle the complete installation of LPG or Natural Gas units. If your current gas line is too small to power a high-capacity instant heater, we can upgrade your pipework to ensure the system never "stutters" when multiple taps are running.
Electric Instantaneous Units
For apartments or homes without gas access, we install 3-phase electric instantaneous systems. These are perfect for under-sink installations or small dwellings where space is at a premium.
Digital Temperature Controllers
We can install optional wall-mounted controllers (like the Rinnai Kitchen/Bathroom remotes) that allow you to set your water temperature to the exact degree. This removes the need to mix cold water, further increasing your energy efficiency.
TMV & Safety Compliance
Safety is non-negotiable. Every instant system we install includes a Tempering Valve (TMV). This ensures that while the water inside the unit is hot enough to kill bacteria, the water coming out of your taps is at a safe 50°C to prevent accidental scalding.
What is an Instant Hot Water System?
- Energy efficiency and lower operating costs
- Continuous hot water availability during peak usage
- Space utilisation due to compact wall-mounted design
- Temperature consistency across multiple fixtures
- Reduced standby heating energy consumption

Frequently Asked Questions
Will my water pressure drop with an instant system?
If installed correctly by a professional, you should not notice a significant drop. We ensure your pipe sizing is adequate to feed the unit the volume of water it needs to operate at peak performance.
Is it expensive to switch from electric storage to gas instant?
While the initial setup involves installing gas lines and potentially upgrading pipes, the long-term energy savings usually offset the cost within a few years. Plus, the increased property value and endless hot water provide immediate benefits.
Do instant hot water systems work in winter?
Yes. Modern units like the Rheem 27 are designed to handle “low inlet temperatures.” They automatically adjust the burner strength to ensure the water reaches your set temperature even on the coldest Sydney mornings.
How often do these systems need a service?
We recommend a professional flush every 2–3 years to remove any mineral scale buildup, ensuring the heat exchanger remains efficient and your lifetime warranty stays protected.
