The Rinnai Infinity A26 is one of the most popular continuous flow water heaters installed across Auckland homes. It delivers a strong, consistent flow of hot water on demand, and it only fires up when you turn on the tap. No cylinder, no standby heat loss, no running out of hot water mid-shower.
At Water & Gas Worx, we supply and install the full Rinnai Infinity range throughout Auckland. Whether you are replacing an old hot water cylinder in Mt Eden, upgrading from a low-pressure system in Remuera, or fitting out a new build in Hobsonville, the Rinnai Infinity A26 is a proven choice for households that need reliable hot water without compromise.
Warranty
Rinnai backs the Infinity range with solid warranty coverage. You can expect a 10-year warranty on the heat exchanger (the most critical component) and a 3-year warranty on parts and labour. This is competitive with other brands in the market and reflects Rinnai's confidence in the product's durability.
Why the Rinnai Infinity A26
The A26 delivers 26 litres per minute of hot water. In practical terms, that is enough to run two showers at the same time without any drop in temperature or pressure. For most Auckland households with one or two bathrooms, the A26 is the ideal size.
The unit is wall-mounted on the exterior of your home, which means it frees up the space your old hot water cupboard used to occupy. No more bulky cylinder taking up room inside the house. The compact design sits neatly against an outside wall and connects directly to your gas supply and plumbing.
From an efficiency standpoint, continuous flow is hard to beat. Unlike a traditional cylinder that heats and reheats water around the clock, the Rinnai Infinity only uses gas when a hot tap is open. When the tap closes, the burner shuts off. You are not paying to keep 180 litres of water hot while you are at work or asleep. For families across Ellerslie, Panmure, and the wider Auckland region, this translates to noticeable savings on monthly gas bills.
Models in the Rinnai Infinity Range
The Infinity range comes in four sizes, and choosing the right one depends on how many hot water outlets you need to run at the same time.
- A16 — 16 litres per minute. Suitable for small homes, apartments, or single-bathroom properties. Handles one shower comfortably.
- A20 — 20 litres per minute. A good mid-range option for homes with one bathroom and a kitchen running simultaneously.
- A26 — 26 litres per minute. The most popular model. Handles two showers running at once. Ideal for the majority of Auckland homes.
- HD56 — up to 37 litres per minute. A high-demand commercial-grade unit for larger homes and light commercial applications. If you have three or more bathrooms or need serious hot water capacity, the HD56 delivers.

Natural Gas vs LPG
The Rinnai Infinity range is available in both natural gas and LPG models. If your property is connected to the natural gas network, as many homes in Grey Lynn, Ponsonby, and central suburbs are, a natural gas model connects directly to your existing gas meter. For properties without mains gas, particularly in areas like Beachlands, Maraetai, and rural East Auckland, the LPG model runs from 45kg gas bottles or a bulk LPG tank.
Both versions deliver the same performance. The main difference is fuel supply and running cost. We handle the full installation for either setup, including gas pipework, regulator fitting, and the required gas safety certificate.
Considering Your Options
The Rinnai Infinity is not the only continuous flow unit on the market. If you want to compare, we also supply and install the Rheem Metro range. See our Rheem Integrity continuous flow page for a full rundown on that alternative. Both are quality units backed by strong warranties, and we can advise which is the better fit for your property and budget.
