Rinnai Hot Water Systems
Rinnai is the name most Sydney homes think of for continuous flow — and for good reason. We supply, install and service the full Rinnai range, from the Infinity continuous flow units to gas storage and heat pumps.
Australia's continuous flow leader
Rinnai built its reputation on continuous flow gas hot water, and its Infinity range is the benchmark other brands are measured against — endless hot water, strong flow rates, and a reliability record that's made it the default choice for Sydney plumbers and homeowners alike.
That track record is why we install so many of them. When a Rinnai goes in, parts and service support are easy to get for years, the units hold up, and the continuous flow models in particular are hard to beat for a home that's tired of running out of hot water.

The Rinnai systems we supply & install
Rinnai isn't just continuous flow — we install across the range and match the right one to your home.
Infinity continuous flow
The flagship — endless hot water, sized by flow rate for single or multi-bathroom homes. The range most people come to Rinnai for, and our most-installed Rinnai system.
Gas storage
Rinnai gas storage tanks for homes that want a ready tankful and a simpler, lower-upfront swap, backed by the same parts and service network.
Heat pumps
Rinnai has moved into heat pumps too — the all-electric, rebate-eligible option for homes cutting running costs, with Rinnai's support behind it.
Why Rinnai — and what to check
Rinnai is a safe, strong choice for most homes. Here's the honest picture.
Why Rinnai
- Market-leading continuous flow — endless hot water, proven reliability.
- Parts and service support are easy to get across Sydney for years.
- A model for almost every home — continuous flow, storage or heat pump.
What to check
- Continuous flow needs the right flow rate for your bathrooms — we size it so it never runs cool.
- Gas models need a gas supply; heat pumps need airflow and a sensible spot.
- We'll tell you honestly if another brand suits your situation better.
Rinnai pricing and installation
Itemised, honest, and sized right.
The right Rinnai depends on your home — the model, the size and your site all move the price — so we quote on what we can see rather than a headline figure. You get an itemised Rinnai hot water price: the unit, the install to code (tempering valve and all), and any site-specific extras shown separately.
We're a supply-and-install service, not a shop. We help you choose the right Rinnai, supply it, install it, and take the old system away — one team across Sydney, and we come to you.

We don't just install Rinnai — we repair and service them too. If your Rinnai is throwing a fault code, running cold or needs its regular service, we carry common Rinnai parts and can get most units back to full hot water fast.
Rinnai systems come with a strong manufacturer warranty, and we handle the warranty support so you're not stuck between the manufacturer and the installer. One team for the life of the system — see our hot water repairs, and keep your Rinnai on our service schedule to get the most years out of it.
