Meet the Rinnai Infinity 26

The Rinnai Infinity is the continuous-flow range most Sydney plumbers reach for first. It heats water the instant you open a tap and never runs out, and the range is sized by flow rate so you can match it to a single bathroom or a busy multi-bathroom home. The Rinnai Infinity 26 — 26 litres a minute — is the one built for homes running several outlets at once.

What sets Infinity apart is the combination of strong flow, smart temperature control (set an exact temperature at a wall controller) and a parts-and-service network that keeps it running for years. With no tank to corrode, a well-installed Infinity routinely outlasts a storage system. People searching for rinnai infinity 26 price or rinnai infinity 26 installed in Sydney are after exactly this — supplied, installed and serviced.

Why the Infinity leads continuous flow

What this range is really about.

Endless, precise hot water

Heats on demand and holds a set temperature at the tap — no tank to drain, no running cold mid-shower.

Sized by flow rate

16, 20 and 26 L/min models suit anything from a unit to a multi-bathroom home. The Infinity 26 handles several showers at once.

Built to last

No tank to corrode plus Rinnai's parts network means a long, well-supported life — one reason it's the category benchmark.

FAQ

Rinnai Infinity 26 FAQs

Questions we're asked most about this range.

Which Rinnai Infinity size do I need?
It's sized by flow rate: around 16 L/min for a single bathroom, 20 L/min for most homes, and the Infinity 26 (26 L/min) for multiple bathrooms running at once. We size it to your peak so it never goes cool.
Does the Rinnai Infinity ever run out of hot water?
No — it heats on demand as water flows, so it can't drain like a tank. The only limit is flow rate: size it correctly for your simultaneous outlets and everyone gets hot water at once.
Can I set an exact temperature?
Yes — the Infinity range supports wall-mounted temperature controllers, so you set a precise delivery temperature rather than mixing at the tap. It's one of the range's real conveniences.
How long does a Rinnai Infinity last?
A quality continuous-flow unit like the Infinity commonly lasts 15–20 years with servicing, as there's no tank to corrode — longer than most storage systems.
What does a Rinnai Infinity cost installed?
The Rinnai Infinity 26 price and the smaller models depend on the size and your site. We quote it itemised — unit, install and any extras separately — rather than a headline figure.
Do you supply and install the Infinity across Sydney?
Yes — we supply, size, install to code and service the full Rinnai Infinity range Sydney-wide, and we come to you.
