    What is an STC?

    STC stands for Small-scale Technology Certificate. It is part of an Australian Government scheme designed to encourage energy-efficient hot water systems and other eligible renewable technologies.

    How does it work?

    When your new system qualifies, STCs are created based on the expected energy savings and location of the installation. These certificates have a value, and that value is applied as an upfront discount to help reduce the installed cost.

    How is it shown on our jobs?

    For eligible systems, the STC value is already included as a flat rate $1000 upfront discount in the total installed price shown, so you do not need to claim it separately after installation.

    Who is eligible?

    Eligibility generally applies to installations of approved systems at Australian homes and businesses where the product, property type, and installation details meet current STC program requirements.

    If you are unsure whether your property or system qualifies, contact us before ordering and we can help confirm it.

PRODUCT OVERVIEW

What Is the Rinnai Hotflo 135L Medium Capacity Gas Hot Water Storage?

The Rinnai Hotflo 135L is a gas storage hot water system designed to heat and store water inside a 135 litre cylinder.

Unlike a continuous flow water heater, which heats water as it passes through the appliance, the Hotflo 135L maintains a stored volume of heated water ready for household use.

When hot water is drawn from the tank, incoming cold water replaces it and the gas burner reheats the stored water as required.

The system uses a vitreous enamel lined steel cylinder with inbuilt anode protection as part of its tank construction.

With 135 litres of storage capacity and up to 209 litres of first-hour hot water delivery, it is designed for households requiring more hot water than smaller storage systems can typically provide.

The Hotflo 135L is designed for outdoor installation and may suit homes already equipped with a compatible external gas storage hot water system.

Correct system selection still depends on the property's gas supply, household hot water demand, plumbing layout, installation space and current compliance requirements.

Why Choose the Rinnai Hotflo 135L Gas Storage Hot Water System?

Practical Family Capacity

A 135 litre cylinder provides stored hot water for suitable medium-sized households.

Strong First-Hour Delivery

Up to 209 litres in the first hour combines stored capacity with gas reheating performance.

4.7 Star Efficiency Rating

Manufacturer-stated energy rating that helps when comparing gas storage models.

Multiple Outlet Use

Designed to supply hot water to multiple showers and taps where plumbing and household demand are suitable.

Established Cylinder Protection

Vitreous enamel lined steel tank with inbuilt anode protection.

Practical Replacement Option

Worth considering where an existing external gas storage system is being replaced and compatible services are available.

HOUSEHOLD SIZING

Is the Rinnai Hotflo 135L Right for Your Home?

The Rinnai Hotflo 135L is designed for medium-sized households requiring a practical balance between stored hot water capacity and gas reheating performance.

The model is positioned for households of up to approximately five people, depending on climate and actual hot water usage.

However, household size is only one factor in selecting the correct hot water system.

Shower duration, the number of bathrooms, simultaneous outlet use, laundry demand and peak household usage periods can all influence the required capacity.

Potentially Suitable Homes

Medium-sized households with compatible gas supply, suitable outdoor installation space and demand that matches a 135 litre gas storage heater.

Homes That May Need Another Option

Properties without suitable gas services, homes lacking a compliant outdoor installation location or households with unusually high sustained hot water demand.

The Hotflo 135L may be particularly practical where an existing external gas storage heater is being replaced and the property can retain a similar installation arrangement.

JR Gas & Water assesses household usage, gas availability, plumbing and outdoor installation conditions before confirming suitability.

HOT WATER PERFORMANCE

What Does 209 Litres of First-Hour Hot Water Delivery Mean?

The Rinnai Hotflo 135L has a stated first-hour hot water delivery of up to 209 litres.

First-hour delivery is different from the volume of water physically stored inside the cylinder.

The tank stores 135 litres, while the first-hour rating reflects the hot water available during the initial hour of operation under specified test conditions, including the contribution from gas reheating.

135 Litres

Nominal hot water storage capacity inside the cylinder.

Up to 209 Litres

Stated hot water delivery during the first hour under rated conditions.

This distinction matters when comparing gas storage systems because the physical tank capacity alone does not describe the complete first-hour hot water delivery capability.

Actual household performance depends on incoming water temperature, outlet temperature, draw-off patterns, burner operation and simultaneous usage.

The first-hour rating does not mean the system provides unlimited hot water.

Can the Rinnai Hotflo 135L Supply Multiple Showers and Taps?

The Rinnai Hotflo 135L is designed to deliver strong, consistent hot water pressure to multiple outlets where the property's plumbing and demand are suitable.

This makes it worth considering for family homes where hot water may be used in the bathroom, kitchen and laundry during overlapping periods.

However, actual water pressure and flow depend on the property's incoming water supply, pipe sizing, valves and fixtures.

Using several hot water outlets simultaneously also increases the rate at which stored hot water is consumed.

For households with unusually high simultaneous demand, a larger storage system or a suitably sized continuous flow unit may be more appropriate.

INSTALLATION LOCATION

Rinnai Hotflo 135L Outdoor Installation Requirements

The Rinnai Hotflo 135L is designed for external installation only.

The installation position must comply with current manufacturer instructions and applicable gas installation requirements.

The location needs sufficient space for the cylinder, gas connections, water pipework, valves, drainage and servicing access.

Clearances around the appliance and its combustion and flue arrangements must also be considered.

The heater must not be installed inside a building or an unsuitable enclosed location.

Outdoor installation does not automatically mean every external location is acceptable.

JR Gas & Water assesses the proposed position, surrounding structures, access and service connections before confirming installation suitability.

Rinnai Hotflo 135L Gas Supply Requirements

The Rinnai Hotflo 135L must be connected to a suitable gas supply that matches the selected appliance's specifications.

Gas supply assessment is particularly important when replacing an older water heater with a different model or gas input requirement.

Important considerations include:

Correct appliance gas type
Adequate gas supply capacity
Suitable gas pipe sizing
Correct supply pressure
Gas isolation arrangements
Existing regulator suitability
Gas connection compatibility
Licensed gasfitting and commissioning

The exact gas variants, gas input rating and connection requirements should be confirmed against the current Rinnai specification for the selected model.

Gas appliances must not be connected to an incompatible gas type or unsuitable supply.

Gas installation and connection work must be completed by appropriately licensed gasfitting personnel.

Vitreous Enamel Lined Steel Tank and Anode Protection

The Rinnai Hotflo 135L features a vitreous enamel lined steel cylinder.

Vitreous enamel lining is used in many storage water heaters to help protect the steel cylinder from direct contact with stored water.

The Hotflo 135L also incorporates inbuilt anode protection as part of its corrosion protection system.

These features are important for long-term tank protection, but performance still depends on water quality, operating conditions and correct maintenance.

Anode inspection or replacement requirements should be confirmed against current Rinnai maintenance instructions.

Water quality requirements and recommended servicing should be followed throughout the heater's service life.

How Does the Rinnai Hotflo 135L Gas Storage Water Heater Work?

1. Cold water enters the cylinder: Water enters the storage tank through the cold water supply connection.

2. Gas heats the stored water: The gas burner transfers heat into the stored water.

3. Temperature is regulated: The appliance controls heating according to its operating configuration.

4. Hot water is stored: Heated water remains in the 135 litre cylinder until required.

5. Hot water is delivered: Opening a hot water outlet draws heated water from the storage tank.

6. The system reheats: Replacement cold water is heated as required, contributing to the system's first-hour hot water delivery.

Actual recovery performance depends on the manufacturer's rated operating conditions and the property's gas supply.

Can the Rinnai Hotflo 135L Replace Your Existing Gas Storage Water Heater?

The Rinnai Hotflo 135L may be a suitable replacement for an existing external gas storage hot water system.

It can be particularly practical where the property already has a compatible gas connection, suitable outdoor installation position and household demand that matches a 135 litre storage heater.

However, a like-for-like gas storage replacement is not always a direct swap.

Before confirming replacement suitability, JR Gas & Water considers:

Existing hot water system capacity
Actual household hot water demand
Existing gas supply type
Available gas supply capacity
Gas pipe sizing and pressure
Outdoor installation location
Combustion and flue clearances
Available installation dimensions
Existing water pipework positions
Valve and pressure control requirements

Removal and installation access

Where the existing system has different dimensions, gas input requirements or connection positions, additional work may be required.

JR Gas & Water assesses the existing installation before confirming the appropriate replacement scope.

What's Involved in Installing the Rinnai Hotflo 135L?

1. Assess the Property

Review household hot water demand, gas supply, outdoor installation position, plumbing, valves, drainage and access.

2. Supply and Install

Supply the selected Rinnai Hotflo 135L, remove the existing heater where included, position the replacement and complete suitable gas and water connections.

3. Test and Commission

Check water and gas connections, test for leaks, verify burner operation, commission the heater and confirm appropriate hot water delivery.

Additional work may be required for unsuitable gas supply arrangements, valve upgrades, plumbing modifications, base preparation, drainage or relocation.

JR Gas & Water aims to make the installation scope clear before work proceeds.

SUPPLY & INSTALL PRICING

How Much Does Rinnai Hotflo 135L Installation Cost in Brisbane or the Gold Coast?

Rinnai Hotflo 135L gas storage installed pricing depends on the selected appliance and the work required at the property.

A straightforward replacement in a suitable existing outdoor location is generally simpler than an installation requiring gas pipework upgrades, plumbing alterations or relocation.

Factors affecting installation cost include:

Rinnai Hotflo 135L unit supply
Correct gas model selection
Removal of the existing heater
Existing gas connection suitability
Gas pipe sizing and pressure
Gas isolation requirements
Outdoor installation location
Combustion and flue clearances
Water pipework compatibility
Water pressure conditions
Pressure limiting requirements
Relief valve requirements
Temperature limiting requirements
Drainage improvements
Base preparation
Relocation or additional pipework

No fixed installed price is stated because the final cost depends on the property's existing services and required work.

JR Gas & Water can assess the installation and determine the appropriate supply and installation scope.

Rinnai Hotflo 135L Running Costs and Gas Consumption

The Rinnai Hotflo 135L uses gas to heat and maintain water stored inside its cylinder.

The supplied product information identifies a 4.7 star energy rating.

Actual running costs depend on household hot water demand, incoming water temperature, gas pricing, storage heat losses and the selected appliance configuration.

Gas storage systems use energy both to heat water after it has been drawn and to maintain stored water temperature.

A 4.7 star rating provides an efficiency reference, but it does not establish a fixed daily or annual running cost for every household.

For an accurate running cost comparison, current manufacturer gas consumption data and the property's applicable gas pricing should be considered.

Rinnai Hotflo 135L Gas Storage vs Continuous Flow Hot Water

The Rinnai Hotflo 135L uses a storage tank, while continuous flow gas water heaters heat water on demand.

Consideration Rinnai Hotflo 135L Gas Storage Gas Continuous Flow
Heating Method Stores and reheats water in a 135L cylinder Heats water as it flows through the appliance
Stored Hot Water 135 litres Generally no large storage cylinder
Hot Water Delivery Up to 209 litres in the first hour under rated conditions Depends on the model's rated flow capacity
Installation Space Requires suitable outdoor space for a storage cylinder Typically uses a more compact wall-mounted appliance
Gas Supply Requirements Must meet the storage heater's gas input requirements Must meet the selected continuous flow unit's gas input requirements
Replacement Consideration May suit existing external gas storage installations May require different gas, water and mounting arrangements

Neither system type is automatically the best choice for every home.

The correct choice depends on household demand, available gas supply, installation location, budget and operating priorities.

Rinnai Hotflo 135L vs Larger Gas Storage Hot Water Systems

The Rinnai Hotflo 135L provides medium-capacity stored hot water for suitable households.

Properties with greater daily demand may benefit from a larger gas storage system, while properties with lighter demand may not require the same storage capacity.

Smaller Gas Storage

May suit properties with lighter demand, depending on available models and installation requirements.

Rinnai Hotflo 135L

135 litre storage capacity with up to 209 litres of first-hour hot water delivery under stated conditions.

Larger Gas Storage

May suit households needing greater stored hot water capacity or stronger peak demand performance.

A larger tank is not automatically better. Correct sizing depends on household demand, recovery performance and installation suitability.

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

A gas hot water system should not be selected on upfront purchase price alone.

Correct sizing, gas compatibility, tank construction, installation suitability and long-term serviceability all affect the ownership experience.

The Rinnai Hotflo 135L offers a 135 litre storage capacity, up to 209 litres of first-hour hot water delivery, a 4.7 star energy rating and a vitreous enamel lined steel cylinder with anode protection.

However, even a recognised system can be unsuitable if the gas supply is inadequate, the outdoor location does not meet installation requirements or the capacity does not match household demand.

JR Gas & Water focuses on selecting the appropriate system and completing the installation correctly rather than treating every hot water replacement as a simple tank swap.

Rinnai Hotflo 135L Maintenance and Long-Term Care

The Rinnai Hotflo 135L should be maintained in accordance with current manufacturer instructions.

As a gas storage water heater with a vitreous enamel lined steel cylinder and anode protection, the system may require periodic inspection and servicing of relevant components.

Signs that the system may need professional attention include:

Reduced hot water availability
Unexpected temperature changes
Unusual burner operation
Water leaking from the cylinder
Unusual relief valve discharge
Repeated burner shutdowns
Visible corrosion or damaged fittings
Leaking plumbing connections

Anode maintenance, valve servicing and other inspection intervals should be confirmed against current Rinnai documentation.

Gas appliance servicing and repairs must be carried out by appropriately licensed personnel.

Rinnai Hotflo 135L Gas Storage Warranty

The Rinnai Hotflo 135L is subject to the manufacturer's warranty arrangements for the selected model and application.

Exact cylinder, parts and labour warranty periods should be confirmed from the current Rinnai warranty statement.

Warranty eligibility may depend on correct installation, water quality, maintenance, operating conditions and whether the system is used in a domestic or commercial application.

Manufacturer product warranty coverage is separate from any JR Gas & Water installation workmanship warranty.
