Rinnai Infinity

The Rinnai Infinity range is a continuous flow gas hot water system designed with the environment in mind.

As its name implies, the Rinnai Infinity continuous flow hot water system never runs out of hot water. Back in the early 90s, when this systems was first designed, it was a revolutionary idea.

It works by heating water as it passes through the unit on its way to your tap. Compared to storage heating units, this method uses far less energy because it only heats the right amount of water when it’s needed.

Rinnai Infinity offer a very wide range of models. Which model is right for your house largely depends on how many people are using the system and which type of climate you are living in.

The INFINITY range awarded an energy efficiency rating over 5 stars.

INFINITY gets its name from its continuous flow technology. When you turn on your hot water tap, the system heats the water as it passes through the unit on the way to the tap.

Unlike conventional storage heating units that have a maximum litre capacity of pre ted water. Which can leave you without hot water if you use all the water in its tank.

The INFINITY can instantly provide you with more hot water when you need it so you can never, ever run out.

An added bonus of the continuous flow system is that the unit is only using energy when its heating water, not constantly running to heat its stored water.

This highly efficient technology means reduced running costs and far less greenhouse gas emissions.

Each INFINITY unit hardware is made with quality Japanese design and manufacturing. It comes in a compact design for easy external installation. It also has bonus features including antifrost protection to combat any colder Australian climates.

Rinnai offer comprehensive warranties on each INFINITY unit. A 12-year warranty on the heat exchanger (an internal part), and a 3-year warranty on all other parts.

Jim’s Plumbing are experts in maintaining and installing Rinnai INFINITY units.

We install a variety of units from the INFINITY Classic Model Range from a 16 litre per minute unit, to a 32 litre per minute option.

All models are suitable for external installation. They are available in both 50 and 60 degrees and in either natural gas or LPG. It’s allowing you maximum flexibility of choice to find a model that suits your needs.

Before choosing to install a Rinnai INFINITY; it is important to know that the INFINITY requires a minimum water flow rate of 4 litres per minute. Otherwise the continuous flow system will not work as it will not sense that a hot water tap is on.

Your water flow rate can be restricted if the diameter of your gas pipe is small or if you have water saving showerhead or similar device installed that restricts water flow.

Please ask Jim’s Plumbing about whether the set up in your home is INFINITY compatible.

Optional Water Controllers

An advantageous benefit of choosing a Rinnai INFINITY hot water heater is the option of installing Rinnai Water Controllers. That enable you to have total control of your hot water use.

The Controller’s functions allows you to select your exact desired water temperature. Including making sure that the temperature remains within a safe range to reduce the chance of scalding.

A fantastic safety feature for families with children, or the elderly.

The controllers also make sure that you avoid any temperature fluctuations. Which can be experienced by all types of water heaters, as they maintain a precise temperature even when other taps in the house are being used.

With each INFINITY unit, up to four of these easy to use controllers can be installed within your home. With wired (wall mounted) and wireless (portable) options available.

Additionally, Rinnai provided an extended parts and labour warranty. From 3 years to 5 years warranty with INFINITY systems that include installation of 2 or more water controllers.
