Rinnai Infinity 20 Installation in Brisbane & Gold Coast

Looking for Rinnai Infinity 20 installation in Brisbane or the Gold Coast? JR Gas & Water supplies and installs the Rinnai Infinity 20 for homeowners wanting a compact gas continuous flow hot water system that provides on-demand hot water without a conventional storage tank.

The Rinnai Infinity 20 is a 20 litre per minute class gas continuous flow hot water system designed for moderate household hot water demand. It is a practical option for many one to two bathroom homes, depending on how much hot water is needed at the same time.

Rather than storing and reheating a tank of hot water, the Infinity 20 heats water as it passes through the appliance. This avoids conventional storage tank standby heat losses and allows the system to continue supplying hot water while demand remains within its operating capacity.

For homeowners comparing Rinnai Infinity 20 installed pricing, Rinnai Infinity 20 supply and install, gas continuous flow hot water replacement or hot water installation in Brisbane, the most important consideration is whether the appliance suits the property.

Gas supply capacity, water pressure, pipe sizing, incoming water temperature, installation clearances, electrical requirements and household hot water usage all influence the final result.

JR Gas & Water provides professional gas hot water installation across Brisbane, the Gold Coast, Logan, Ipswich, Moreton Bay and Redlands, subject to service availability.

What Is the Rinnai Infinity 20?

The Rinnai Infinity 20 is a gas continuous flow hot water system that heats incoming water as it passes through the appliance.

Unlike a traditional gas storage hot water system, it does not rely on a large insulated cylinder of stored hot water.

Instead, the appliance responds to hot water demand and heats water as required.

The Infinity 20 belongs to the 20 litre per minute nominal flow class, positioning it between smaller 16 litre continuous flow systems and higher-capacity 26 litre or 32 litre models.

It is designed for homes wanting more hot water capacity than a smaller entry-level continuous flow appliance may provide, while retaining the benefits of a compact wall-mounted format.

For many households, this makes the Infinity 20 a practical option where hot water demand is moderate rather than unusually high.

However, bathroom count alone does not determine the correct appliance size.

The number of showers used simultaneously, showerhead flow rates, incoming water temperature and other hot water fixtures must also be considered.

Is the Rinnai Infinity 20 Right for Your Home?

The Rinnai Infinity 20 is generally best suited to homes with moderate hot water demand, particularly one to two bathroom properties where simultaneous hot water usage is not unusually high.

It may be suitable for households wanting more capacity than a smaller 16 litre continuous flow unit without automatically moving to a larger 26 litre or 32 litre model.

A two bathroom home where showers are rarely used together may place less demand on the appliance than a one bathroom home with a high-flow shower and several other hot water fixtures running simultaneously.

JR Gas & Water considers how hot water is actually used before recommending the correct continuous flow capacity.

Can the Rinnai Infinity 20 Run Two Showers?

The Rinnai Infinity 20 offers more nominal flow capacity than a 16 litre class appliance, making it worth considering for selected two bathroom homes.

However, whether it can adequately supply two showers simultaneously depends on the combined hot water flow requirements and the temperature rise required.

Two low-flow showerheads may require substantially less hot water than two high-flow showerheads.

Incoming water temperature also affects available heating capacity.

In South East Queensland, warmer incoming water can reduce the heating requirement compared with colder regions, but this does not guarantee simultaneous shower performance.

Where two showers are regularly used at the same time, a larger continuous flow system may be a more suitable choice.

JR Gas & Water can assess expected fixture demand and determine whether the Infinity 20 provides sufficient capacity.

Rinnai Infinity 20 Gas Supply Requirements

The Rinnai Infinity 20 requires a gas supply capable of supporting the appliance's specified gas input and operating pressure.

Gas continuous flow systems can require substantial instantaneous gas input, even though the appliances are physically compact.

An existing gas line should not automatically be assumed suitable simply because it previously supplied a gas storage hot water system.

Where the existing gas supply cannot support the appliance, additional gasfitting work may be required.

The exact gas input, approved gas types, connection size and operating pressure must be confirmed from current Rinnai specifications.

Rinnai Infinity 20 Water Pressure and Flow Requirements

Water pressure and flow are important for reliable operation of a gas continuous flow hot water system.

The Infinity 20 must receive sufficient water flow to activate and operate correctly.

Low water pressure or restricted pipework may affect hot water delivery, while excessive pressure may require suitable pressure control.

The exact minimum and maximum water pressure limits and activation flow requirements should be confirmed from current manufacturer specifications.

How Does the Rinnai Infinity 20 Work?

1. A hot water tap opens: Water begins flowing through the appliance.

2. Water flow is detected: When the required operating conditions are met, the system initiates its heating cycle.

3. Gas heats the incoming water: Heat is transferred to the water as it passes through the appliance.

4. Temperature is managed: The system regulates heating within its operating capabilities.

5. Hot water travels to the outlet: Heated water moves through the property's plumbing to the shower, tap or other fixture.

6. Heating stops when demand ends: The appliance stops its normal heating cycle when hot water flow ceases.

Because the system heats water on demand, there is no conventional hot water storage tank to maintain between uses.

However, hot water may still take time to reach distant fixtures because cooled water must first move through the pipework.

What Needs to Be Checked Before Installing the Rinnai Infinity 20?

Installing the Rinnai Infinity 20 requires checking the existing property services and confirming that the selected appliance suits the intended installation position.

Depending on the property, additional gasfitting, plumbing, valve, electrical or relocation work may be required.

Rinnai Infinity 20 Replacement Considerations

Before replacing an existing hot water system with the Infinity 20, JR Gas & Water considers the installation and performance requirements.

Rinnai Infinity 20 Installed Price in Brisbane & Gold Coast

The cost of Rinnai Infinity 20 supply and installation depends on the existing hot water system, property services and installation requirements.

A straightforward replacement with compatible services may involve less work than a conversion from storage hot water or an installation requiring gas supply upgrades.

Factors that can affect the installed price include:

Final installation pricing depends on the property and agreed scope of work.

JR Gas & Water assesses what is required for a suitable and compliant installation rather than assuming every hot water replacement involves identical work.

Rinnai Infinity 20 vs 16L, 26L and 32L Continuous Flow Systems

The Infinity 20 sits between smaller and larger gas continuous flow capacity classes.

The appropriate size depends on the amount of hot water the household needs at the same time.

These are general nominal flow classes, not a confirmation of current Rinnai model availability or guaranteed delivery rates under all conditions.

Actual performance depends on the appliance, incoming water temperature, required temperature rise and available services.

Rinnai Infinity 16 vs Rinnai Infinity 20

The Infinity 20 offers a higher nominal flow class than the Infinity 16.

A 20 litre class appliance has a nominal flow rating 4 litres per minute higher than a 16 litre class appliance, representing a 25% increase by rating.

This can make the Infinity 20 worth considering where a smaller appliance may struggle with the property's expected hot water demand.

However, selecting a larger model does not automatically resolve gas supply, water pressure or pipework limitations.

Both appliance capacity and installation suitability need to be assessed together.

Why Choose a Quality Hot Water System Instead of a Cheaper Alternative?

A cheaper hot water system is not always the better result once installation suitability, efficiency, reliability and household demand are considered.

With gas continuous flow systems, choosing purely on upfront price can result in an appliance that is undersized for the property's hot water requirements.

The Rinnai Infinity 20 is designed as a compact continuous flow solution for moderate residential demand.

Its value comes from being appropriately matched to a suitable home rather than simply offering a particular nominal flow rating.

Even a quality system can disappoint if the gas supply is inadequate, the appliance is incorrectly sized or the installation location is unsuitable.

JR Gas & Water focuses on selecting the right product and completing the installation correctly.

Rinnai Infinity 20 Warranty

Warranty coverage for the Rinnai Infinity 20 depends on the exact appliance model, installation application and current Rinnai warranty terms.

The supplied product information does not establish specific warranty periods.

Before purchase, current manufacturer documentation should be checked for:

Manufacturer product warranty and installation workmanship warranty are separate considerations.
