Rinnai Infinity 12 Installation in Brisbane & Gold Coast

Looking for Rinnai Infinity 12 installation in Brisbane or the Gold Coast? JR Gas & Water provides supply, replacement and installation services for homeowners wanting a compact gas continuous flow hot water system designed for lighter household demand.

The Rinnai Infinity 12 is a 12 litre per minute class gas continuous flow hot water system that heats water on demand rather than storing heated water in a conventional storage cylinder.

It is generally positioned for single bathroom homes, smaller households, studios, granny flats and other lower-demand applications where simultaneous hot water usage is limited.

Unlike a storage hot water system, the Rinnai Infinity 12 does not maintain a large tank of heated water throughout the day. Instead, it heats water as required when a hot water outlet is opened and the appliance's operating conditions are met.

Its compact design can be attractive for properties where available installation space is limited, particularly when replacing an older gas hot water system.

However, the right result depends on more than the unit's nominal flow rating. Gas supply capacity, water pressure, pipe sizing, mounting location, clearances and actual hot water demand all influence whether the Rinnai Infinity 12 is appropriate.

JR Gas & Water provides Rinnai Infinity 12 supply and installation across Brisbane, the Gold Coast, Logan, Ipswich, Moreton Bay and Redlands, subject to service availability and property suitability.

Rinnai Infinity 12 at a glance: The Rinnai Infinity 12 is a compact gas continuous flow hot water system in the 12 litre per minute class. It heats water on demand without a conventional storage tank and is generally suited to smaller homes and single bathroom applications with limited simultaneous hot water demand. Correct sizing, gas supply capacity, water pressure, mounting clearances and plumbing compatibility must be checked before installation.

PRODUCT OVERVIEW

What Is the Rinnai Infinity 12?

The Rinnai Infinity 12 is a gas continuous flow hot water system designed to heat water as it is needed.

When a suitable hot water outlet is opened, water flows through the appliance and the gas heating system operates according to the unit's controls and operating requirements.

This provides hot water without the need for a conventional storage tank.

The model is described as a 12 litre per minute class appliance, making it a smaller-capacity option within the broader continuous flow category.

It is generally positioned for properties with lighter demand rather than larger homes requiring several high-flow hot water outlets at the same time.

Its compact format can make it attractive for smaller homes, studios and suitable secondary dwellings.

However, the exact delivered hot water flow depends on operating conditions, including incoming water temperature, required temperature rise and available services.

Before selecting the Rinnai Infinity 12, JR Gas & Water considers the home's actual usage requirements and whether the available gas and water services can support the appliance.

Why Choose the Rinnai Infinity 12?

Hot Water on Demand

Heats water when required instead of storing a large volume of preheated water.

Compact Installation

May be suitable for homes where a conventional storage cylinder would occupy valuable space.

Lower-Demand Applications

A practical capacity class to consider for smaller households and single bathroom properties.

No Conventional Storage Losses

Does not maintain a large heated storage cylinder between hot water uses.

Gas Hot Water Replacement

May suit properties already equipped with suitable gas supply and plumbing connections.

Established Hot Water Brand

Rinnai is a recognised manufacturer of residential gas continuous flow hot water systems.

HOUSEHOLD SUITABILITY

Is the Rinnai Infinity 12 Suitable for Your Household?

The Rinnai Infinity 12 is generally best suited to homes with lighter hot water requirements.

It is particularly worth considering for single bathroom properties where only one major hot water outlet is normally used at a time.

Potential applications include smaller homes, compact residential properties, studios and suitable granny flats.

However, a 12 litre per minute class rating does not mean the appliance will deliver that flow under every operating condition.

Available hot water flow depends on incoming water temperature, the required temperature rise and the appliance's operating capacity.

Simultaneous use of a shower, kitchen tap and other hot water outlets can increase demand beyond what a smaller continuous flow appliance is intended to supply.

Household size alone is not enough to determine suitability. Shower flow rates, outlet use, peak demand and expected future requirements should also be considered.

JR Gas & Water assesses these factors before recommending the Rinnai Infinity 12.

Where Does the Rinnai Infinity 12 Make Sense?

Single Bathroom Homes

May suit properties where hot water demand is generally concentrated around one bathroom and simultaneous usage is limited.

Small Households

Can be worth considering where daily hot water demand is modest and the appliance is correctly sized.

Studios and Compact Dwellings

Its compact design may appeal where space is limited and hot water demand is relatively low.

Granny Flats

May suit eligible secondary dwellings where gas services, mounting conditions and hot water demand are appropriate.

Existing Gas Hot Water Replacements

May provide a replacement option where the existing installation services are suitable or can be upgraded appropriately.

Properties With Limited Storage Space

Does not require the physical footprint of a large hot water storage cylinder.

How Does the Rinnai Infinity 12 Continuous Flow Hot Water System Work?

1. A hot water outlet opens: Water begins flowing through the appliance when a household hot water tap or shower is turned on.

2. The appliance detects suitable flow: The system operates when its activation and service conditions are met.

3. Gas heating begins: The appliance uses gas combustion to heat water passing through its heat exchanger.

4. Heated water travels to the outlet: Hot water moves through the household plumbing to the open tap or shower.

5. Heating responds to demand: The unit operates according to its controls, flow conditions and heating capacity.

6. Heating stops when demand ends: When hot water flow stops, the appliance no longer needs to continue heating water for that outlet.

The exact ignition, control and operating arrangements depend on the specific Rinnai Infinity 12 variant.

What Does 12 Litres Per Minute Mean?

The Rinnai Infinity 12 is described as a 12 litre per minute class continuous flow hot water system.

This rating identifies its general capacity class, but it should not be interpreted as a guaranteed hot water delivery rate under every condition.

Continuous flow water heaters have a finite heating capacity.

When incoming water is colder, the appliance must provide a greater temperature rise to reach the required hot water temperature.

A greater temperature rise can reduce the volume of water the appliance is able to heat per minute.

Similarly, a smaller temperature rise may allow a higher flow within the appliance's operating limits.

The precise rated flow conditions, temperature rise and heating input should be confirmed from Rinnai's technical documentation for the exact model.

Correct sizing should be based on the expected hot water demand at the property's outlets rather than relying only on the model number.

Does the Rinnai Infinity 12 Provide Endless Hot Water?

A continuous flow hot water system can keep heating water while a suitable hot water outlet remains open and the appliance's operating conditions are met.

Unlike a conventional storage tank, it does not rely on a fixed volume of preheated water that is gradually depleted during use.

This is why continuous flow systems are often described as providing continuous or endless hot water.

However, continuous hot water does not mean unlimited hot water flow.

The Rinnai Infinity 12 still has a finite heating capacity.

If several outlets operate simultaneously and the combined demand exceeds the appliance's capacity, the system may not provide the desired flow and temperature at every outlet.

For this reason, the Infinity 12 is generally better suited to lighter demand than larger multi-bathroom applications.

Gas Supply Requirements for the Rinnai Infinity 12

One of the most important installation considerations for the Rinnai Infinity 12 is the property's gas supply.

A gas continuous flow hot water system requires sufficient gas capacity to operate correctly.

The available gas supply must account for the appliance's required input and any other gas appliances operating at the property.

Gas pipe sizing, supply pressure, regulator capacity and existing gas infrastructure can all affect installation suitability.

Replacing an older gas storage water heater with a continuous flow appliance does not automatically mean the existing gas line will be adequate.

Depending on the site, additional gas pipework or other gas supply modifications may be required.

The exact gas consumption, approved gas type and pressure requirements should be confirmed from Rinnai's current technical documentation.

JR Gas & Water assesses the available gas services before confirming installation requirements.

Rinnai Infinity 12 Natural Gas and LPG Compatibility

Gas continuous flow hot water systems are supplied in configurations designed for specific gas types.

Where natural gas and LPG versions are available, the correct appliance must be selected for the property's gas supply.

A natural gas appliance should not be assumed interchangeable with an LPG appliance.

The supplied product information does not identify the exact gas variants available for the Rinnai Infinity 12.

Current natural gas and LPG availability should therefore be confirmed against Rinnai's model listings.

The gas type, supply pressure, pipe sizing and installation arrangement must match the selected appliance.

Water Pressure and Flow Requirements

Water pressure and available flow are important when installing a continuous flow hot water system.

The Rinnai Infinity 12 requires suitable incoming water conditions for reliable operation.

Low water flow may prevent the appliance from activating or operating as intended.

Excessive pressure may require appropriate pressure control measures.

Long pipe runs, restrictive plumbing and simultaneous outlet use can also affect the hot water experience.

The exact minimum activation flow, operating pressure range and maximum inlet pressure should be confirmed from the manufacturer's documentation.

JR Gas & Water considers the property's water supply and plumbing layout when assessing installation suitability.

Hot Water Temperature and Safety Requirements

Hot water temperature is an important safety consideration in residential installations.

Australian plumbing requirements distinguish between stored or heated water temperatures and the temperature delivered to certain household outlets.

The correct installation arrangement depends on the appliance configuration, the property and applicable plumbing requirements.

Some installations may require tempering valves or other temperature control arrangements.

Where compatible temperature controllers are available, their suitability and permitted operating settings should be confirmed for the exact model.

The supplied product information does not establish the Rinnai Infinity 12's available temperature presets or controller compatibility.

These details should be checked against Rinnai's current instructions before installation.

Where Can the Rinnai Infinity 12 Be Installed?

The Rinnai Infinity 12 is described as a compact gas continuous flow hot water system.

Its installation location must comply with the approved appliance configuration and relevant gas installation requirements.

Important considerations include mounting surface suitability, service access, combustion air, flue terminal positioning and clearances from openings or other building features.

The exact permitted mounting location must be confirmed from Rinnai's installation instructions.

A location that previously housed another hot water appliance may not automatically meet the requirements for the Infinity 12.

Relocation may be necessary where existing clearances, pipework or access are unsuitable.

JR Gas & Water assesses the mounting position before confirming the installation scope.

Does the Rinnai Infinity 12 Need Electricity?

Electrical requirements vary between gas continuous flow hot water models and configurations.

Some appliances use electrical power for ignition, controls or other operating functions.

The supplied product information does not verify the exact electrical requirements of the Rinnai Infinity 12.

Power supply, connection requirements and operation during a power outage should therefore be confirmed from Rinnai's technical documentation for the exact model.

Any required electrical work must be completed appropriately as part of the installation.

How Efficient Is the Rinnai Infinity 12?

The Rinnai Infinity 12 heats water on demand rather than maintaining a large heated storage cylinder.

This can avoid the standing heat losses associated with conventional storage water heaters.

However, actual gas consumption and running costs depend on household usage, incoming water temperature, selected delivery temperature and appliance efficiency.

The exact energy efficiency rating and gas input should be confirmed from Rinnai's current technical specifications.

Running costs should not be estimated from the 12 litre per minute capacity alone.

Correct sizing is also important because an appliance that is too small for the property's peak demand may not provide the expected performance.

Rinnai Infinity 12 vs Larger Continuous Flow Hot Water Systems

The Rinnai Infinity 12 is positioned for lighter household hot water demand.

Larger continuous flow appliances may be more appropriate where several bathrooms or high-flow outlets are used simultaneously.

Consideration	Rinnai Infinity 12	Larger Continuous Flow System
Capacity Class	12 litres per minute	Higher nominal flow class
Typical Application	Smaller homes and single bathroom use	Potentially higher-demand homes
Simultaneous Hot Water Demand	Limited-demand applications	Depends on selected capacity
Gas Supply Requirements	Must meet model requirements	May require greater gas supply capacity
Physical Installation	Compact appliance class	Depends on selected model
Best Selection Method	Size to actual outlet demand	Size to actual outlet demand

Choosing a larger appliance is not automatically necessary for every property. The correct size depends on expected hot water demand and available services.

Rinnai Infinity 12 vs Gas Storage Hot Water

The Rinnai Infinity 12 heats water as it is required, while a conventional gas storage system heats and stores a fixed volume of water.

Continuous flow avoids the need for a large heated storage cylinder but has a finite instantaneous heating capacity.

A storage system can deliver hot water from its stored volume, although the available supply eventually reduces as the tank is depleted.

Both technologies require suitable gas services and correct installation.

For a smaller home, a compact continuous flow system may offer a practical alternative to storage.

However, a property with higher simultaneous hot water demand may require a larger continuous flow appliance or a different system arrangement.

Rinnai Infinity 12 vs Electric Storage Hot Water

The Rinnai Infinity 12 uses gas to heat water on demand.

A conventional electric storage water heater uses electricity to heat and maintain a stored volume of hot water.

Continuous flow can reduce the space required for hot water storage, but it depends on a suitable gas supply.

Electric storage may be simpler where suitable electrical and plumbing services already exist.

Installation costs, energy tariffs, household demand and existing infrastructure all influence which system is more appropriate.

JR Gas & Water can assess the practical differences before recommending a replacement approach.

Why Correct Sizing Matters for the Rinnai Infinity 12

A continuous flow hot water system must be sized for the property's expected peak hot water demand.

Choosing a smaller appliance purely because it costs less may lead to disappointing performance where multiple outlets are used at the same time.

Conversely, choosing a substantially larger unit without assessing the property may introduce unnecessary installation costs or gas supply upgrades.

The Rinnai Infinity 12 is intended for lighter-demand applications.

JR Gas & Water considers shower flow rates, number of bathrooms, simultaneous outlet use and available gas services before recommending the correct capacity class.
