Upgrading from a Storage Tank to a Rinnai Continuous Flow Hot Water System
Our team attended a property in Quakers Hill to replace an ageing storage hot water system with a new Rinnai continuous flow gas hot water system.
The project involved removing the existing storage tank, installing new gas and water pipework, coordinating electrical works for a compliant power supply, and commissioning the new system to provide reliable hot water on demand.
For many homeowners, replacing a hot water system isn't just about buying a new unit—it's an opportunity to choose a system that's better suited to the way the household actually uses hot water.
The Biggest Myth About Continuous Flow Hot Water Systems
One of the most common things we hear is:
"Won't we run out of hot water if we don't have a storage tank anymore?"
It sounds logical. After all, a storage system has a large tank full of hot water sitting outside your home.
But here's the part many people don't realise.
Once that tank is empty, it has to heat another full tank of water before you're back to normal.
A continuous flow system works differently.
Instead of storing hundreds of litres of hot water all day, it heats water only when you turn on a hot tap.
As long as the unit is correctly sized for your household, it can continue producing hot water for as long as it's needed. That means no waiting for a storage tank to recover after several showers or a busy morning.
Why This Homeowner Chose a Continuous Flow System
For this property, replacing the existing storage tank with a Rinnai continuous flow unit offered several advantages.
The bulky storage cylinder was removed, freeing up valuable outdoor space and giving the homeowner a much more compact installation.
New copper gas, hot water and cold water pipework was installed to suit the upgraded system before the unit was connected in accordance with Australian Standards and the manufacturer's installation requirements.
A licensed electrician also installed a new weatherproof double GPO to provide compliant power for the new appliance.
Once all services had been connected, the system was pressure tested, commissioned and checked to ensure reliable hot water delivery throughout the home.
Is Continuous Flow Always the Better Choice?
Not necessarily—and that's something many plumbers don't talk about.
Continuous flow systems are an excellent option for many homes, but they aren't automatically the right choice for every property.
The best system depends on factors such as:
- The number of bathrooms.
- How many people live in the home.
- Whether gas is already available.
- Peak hot water demand.
- Future renovation plans.
That's why we always recommend choosing a hot water system based on how your household actually uses hot water, rather than simply replacing like for like.
For this Quakers Hill property, a Rinnai continuous flow system provided an efficient, space-saving solution that better suited the homeowner's needs while delivering reliable hot water whenever it was required.
