    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.

RINNAI 250L HEAT PUMP HOT WATER

Rinnai Hotflo Plus 250L Heat Pump Installation Brisbane & Gold Coast

JR Gas & Water supplies and installs the current Rinnai Hotflo Plus 250L Heat Pump for eligible Brisbane and Gold Coast homes looking to replace an ageing electric storage system or upgrade to more efficient heat pump hot water.

The current Rinnai EHPG250VMP combines a 250-litre storage cylinder with an air-source heat pump, R290 refrigerant, built-in Wi-Fi, an inbuilt electric backup element and a manufacturer sizing guide of up to five people.

Heat pump performance depends on more than tank size. The installation position needs suitable airflow, drainage, electrical supply, water pressure, access and manufacturer-required clearances. JR assesses the property and installation pathway rather than treating every 250-litre replacement as identical.

Quick answer: the current Rinnai Hotflo Plus 250L is model EHPG250VMP. Rinnai lists it for households of up to five people, with a 250L tank, 46 dB(A) sound level, R290 refrigerant, SmartLife Wi-Fi control, -7°C to 45°C heat-pump operating range and a 7-year cylinder warranty. It is particularly relevant for homes upgrading from conventional electric storage where the site can accommodate a heat pump correctly.

  • Insufficient airflow around the proposed location
  • Another tank capacity better matches actual usage

JR Should Check

  • Existing hot-water system type
  • Available installation footprint
  • Electrical connection
  • Condensate and relief drainage
  • Water pressure and valve arrangement
  • Existing slab or support base
  • Relocation requirements

How Does the Rinnai Hotflo Plus Heat Pump Work?

Instead of producing all of its heat directly with a conventional electric resistance element, the Hotflo Plus uses a refrigeration circuit to collect heat energy from the surrounding air and transfer that energy into the stored water.

This allows the heat pump to move significantly more heat into the tank than would be produced from the same amount of electrical input by a standard resistance element under suitable operating conditions.

The system also includes a 2.4 kW inbuilt electric element, providing an additional heating pathway when required by the system's controls or operating conditions.

COP needs context. Rinnai publishes a COP of 8.5 under a specified test condition of 32.6°C ambient temperature and 21.1°C incoming cold water. Real-world efficiency changes with ambient temperature, inlet-water temperature, usage, settings and installation conditions.

Rinnai Hotflo Plus 250L Key Features

R290 Refrigerant

The current model uses R290 refrigerant with a low published Global Warming Potential.

Built-In Wi-Fi

The Hotflo Plus includes Wi-Fi connectivity for optional control through the third-party SmartLife app.

46 dB(A) Operation

Rinnai publishes a sound level of 46 dB(A) for the current EHPG250VMP.

Electric Backup Element

An inbuilt 2.4 kW electric element provides additional heating capability when required.

Anti-Frost Function

The system includes anti-frost protection for the evaporator in colder operating conditions.

Automatic Restart

Rinnai specifies automatic restart following restoration of power after an outage.

Auto Disinfection

The current Hotflo Plus includes an automatic disinfection function as part of its control strategy.

Off-Peak Scheduling

Rinnai provides the option to configure operation around off-peak electricity periods where the property's tariff and electrical arrangement support it.

STC Eligible

The current EHPG250VMP is listed by Rinnai as eligible under the Federal Small-scale Renewable Energy Scheme, subject to current scheme rules and installation location.

Dimension clarification: Rinnai's detailed current specification lists the actual unit at approximately 1855 mm high × 640 mm diameter. A 2035 mm figure also appears in current Rinnai material as the packaged height and should not be confused with the installed cylinder height.

Electrical Requirements for the Rinnai Hotflo Plus 250L

The current EHPG250VMP operates on a 220–240 V, 50 Hz supply and is supplied by Rinnai with a 15 amp plug. Rinnai also permits the unit to be hardwired where the installation is completed appropriately.

The maximum published rated current is 13.5 amps, with a 2.4 kW electric element and 1.1 kW refrigeration module.

Existing power should be checked before installation. Moving from an older storage system or a different connection type may require electrical alterations. The live installation package and site conditions determine what electrical work is included or additional.

Water Pressure & Valve Requirements

The Hotflo Plus installation needs to comply with Rinnai's current valve and pressure requirements as well as applicable plumbing standards.

Rinnai specifies a supplied 1000 kPa PTR valve. Where an expansion-control valve is installed, a pressure-limiting valve is required if mains pressure exceeds 680 kPa, with Rinnai recommending a 500 kPa PLV. Where an ECV is not fitted, the manufacturer's PLV trigger is different.

JR assesses the installed valve arrangement rather than assuming the old valves can simply be reused. Existing valves, water pressure and the previous system configuration can change the final installation scope.

How Much Does Rinnai Hotflo Plus 250L Installation Cost?

JR's live product selector above displays current installed pricing and available installation packages. That live configuration should remain the pricing source instead of embedding a fixed price into this content.

A straightforward replacement at a suitable existing location will generally require less additional work than a relocation, fuel-type conversion or installation requiring electrical, drainage, valve or base upgrades.

STC eligibility can also affect the effective upfront price of an eligible heat pump installation. Certificate values and scheme rules change over time and depend on the installation, so current live pricing should be used rather than a fixed rebate figure in this description.

Rinnai Hotflo Plus 250L Installation Brisbane

JR Gas & Water supplies and installs the Rinnai Hotflo Plus 250L across eligible Brisbane homes where a heat pump is suitable for the property and household.

For Brisbane replacements, the existing system and proposed location are particularly important. An older electric storage tank can often provide a logical upgrade pathway, but the new heat pump still needs appropriate airflow, condensate management, electrical supply and physical clearance.

JR also services eligible surrounding areas including Logan, Ipswich, Moreton Bay and Redlands, with the live booking options above controlling current availability.

Rinnai Hotflo Plus 250L Installation Gold Coast

JR Gas & Water also provides Rinnai Hotflo Plus 250L supply and installation across eligible Gold Coast properties.

Gold Coast installations can include simple electric-storage replacement jobs as well as more involved upgrades where the heat pump needs a better position, revised drainage or electrical changes.

The objective is to install the system where it can operate with suitable airflow and service access while keeping plumbing runs, acoustic considerations and the practical layout of the property in mind.

Replacing an Electric Storage System With the Rinnai Hotflo Plus

Rinnai specifically promotes the Hotflo Plus 250L as suitable for replacing conventional electric storage hot water.

That does not mean every old 250-litre cylinder location is automatically suitable. A heat pump needs airflow around its evaporator and produces condensate during operation, while the electrical arrangement may also differ from the old system.

Like-for-like capacity is not the only consideration. JR also considers household demand, available location, noise sensitivity, electrical supply, plumbing layout and the condition of the existing installation before confirming the replacement pathway.

Rinnai Hotflo Plus 250L Efficiency

Rinnai states that the Hotflo Plus controller and heat-pump technology can use more than 70% less energy than the comparison basis used in its published material, while still maintaining stored hot-water availability.

Actual household electricity consumption will vary with hot-water use, ambient temperature, inlet-water temperature, operating mode, tariffs, installation and how often the electric element is required.

For that reason, published efficiency figures are useful for comparing technologies but should not be interpreted as a guaranteed household power-bill saving.

How Quiet Is the Rinnai Hotflo Plus 250L?

Rinnai publishes a sound pressure level of 46 dB(A) for the current EHPG250VMP.

That is relatively quiet for heat-pump equipment, but installation position still matters. Sound can be more noticeable near bedroom windows, narrow side passages, reflective walls or neighbouring living areas.

JR considers practical placement as part of the installation rather than relying on the published sound figure alone.

SmartLife Wi-Fi Control

The current Hotflo Plus has a built-in Wi-Fi module and supports optional control through the third-party SmartLife app.

This provides a convenient way to access compatible system controls and scheduling functions without needing to interact only with the unit itself.

App use is optional. Rinnai identifies SmartLife as a third-party service with its own privacy policy and terms. The hot-water system does not depend on the homeowner using remote app control for normal basic operation.

Rinnai Hotflo Plus 250L Warranty

Rinnai currently advertises a 7-year cylinder warranty for the Hotflo Plus 250L, subject to its warranty booklet, installation requirements, maintenance conditions and exclusions.

Do not describe this as a blanket 7-year whole-product warranty. The advertised seven-year period specifically refers to the cylinder. Other components, labour and warranty conditions are governed by Rinnai's current warranty terms.

Any JR installation or workmanship warranty offered with the selected package is separate from Rinnai's manufacturer product warranty and should be read according to JR's current terms.

How Do STC Rebates Work?

Small-scale Technology Certificates, or STCs, are part of the Australian Government’s renewable energy scheme. Eligible heat pump and solar hot water systems can generate STCs, which carry a monetary value. JR Gas & Water applies this value as an upfront rebate so customers see a reduced out-of-pocket price on eligible products rather than needing to claim anything later themselves.

For clarity, JR Gas & Water uses a flat-rate STC rebate of $1,000 including GST on eligible systems. This means the price shown online is the customer’s out-of-pocket price after the rebate has already been applied. It is not the full gross system price before the rebate.

As an example, if a system is advertised online at $4,000, the gross system price is $5,000, less the $1,000 STC rebate, leaving the advertised out-of-pocket amount of $4,000.

This upfront rebate is offered on the basis that the installation will be completed compliantly, the system will remain eligible for STCs, and JR Gas & Water will be able to create, process, and receive the value of those certificates after installation. We handle the STC paperwork and process behind the scenes, but the rebate is conditional and relies on the job proceeding correctly from start to finish.

Who Is Eligible?

In general, customers may be eligible for the STC rebate where they are purchasing an approved solar hot water system, heat pump hot water system, or other eligible product that qualifies under the applicable scheme rules at the time of installation.

Eligibility generally requires that:
the product itself is STC eligible,
the installation address is eligible,
the system is installed in Australia,
the installation is completed in a compliant manner,
the system is capable of being properly verified,
and the customer provides any required information, declarations, signatures, and supporting documents needed to process the STCs.

Where JR Gas & Water advertises an eligible system with the rebate already applied, the customer is agreeing that the STCs will be assigned to JR Gas & Water or its nominated agent as part of the sale. That assignment is what allows the rebate to be applied upfront instead of the customer paying full price.

When Is the Rebate Not Available or Not Valid?

The STC rebate is not an automatic discount in every situation. It is only available where the installation proceeds fully and remains eligible for STC creation and assignment.

A customer may not be eligible, or may be required to repay the rebate amount, where:

the order is cancelled after rebate pricing has been applied,
the customer declines installation,
the site is not ready,
access is refused,
the installation cannot proceed due to hazards, animals, obstructions, or unsafe conditions,
the customer wants to keep the STCs personally,
required paperwork is not signed or returned,
incorrect or incomplete information is provided,
the property or system turns out not to qualify,
the quoted eligible product is changed,
a third party interferes with, alters, completes, disconnects, reconnects, or modifies the installation,
required compliance or upgrade works are refused,
or the installation cannot be lawfully completed in a way that allows the STCs to be validly claimed.

This also includes situations where another contractor performs part of the work in a way that affects eligibility, or where changes made by the customer or another trade prevent JR Gas & Water from receiving the STC benefit that the upfront rebate was based on.

What Happens If the Customer Does Not Proceed?

Where a customer accepts pricing that already includes the STC rebate and then cancels, postpones, declines installation, refuses access, or otherwise prevents the installation from being completed, JR Gas & Water may recover the full $1,000 STC rebate amount in addition to any other applicable cancellation, postponement, restocking, freight, attendance, or administrative charges.

This is because the lower advertised price was offered on the basis that JR Gas & Water would receive the benefit of the STCs after compliant completion of the installation. If the job does not proceed, that STC benefit cannot be recovered by JR Gas & Water, so the rebate amount becomes payable.

Can the Customer Keep the STCs Instead?

Yes, but not at the rebate-adjusted price.

If the customer wishes to keep, trade, or claim the STCs themselves, they must notify JR Gas & Water in writing before the order is accepted, or at the latest before installation begins. In that case, the customer must pay the full $1,000 including GST rebate amount before installation unless otherwise agreed in writing.

Heat pump hot water systems are one of the most energy-efficient ways to heat water, using ambient air to produce hot water while consuming significantly less electricity than a conventional electric storage system.

Like any appliance with refrigeration and mechanical components, regular maintenance is essential to maximise efficiency, maintain reliable performance and support your manufacturer's warranty.

Many manufacturers recommend routine inspections and servicing throughout the life of the system.

Homeowner Maintenance – Every 6 Months

Every six months we recommend carrying out a simple visual inspection of your heat pump system.

Homeowners should:

  • Carefully operate the Pressure & Temperature Relief (PTR) Valve.
  • Operate the Expansion Control Valve (ECV) (where fitted).
  • Remove leaves, grass and debris from around the outdoor unit.
  • Ensure the air inlet and outlet remain clear.
  • Check the condensate drain is free-flowing.
  • Inspect for obvious water leaks or corrosion.
  • Listen for any unusual noises during operation.

Why is this important?

Heat pumps rely on unrestricted airflow to operate efficiently.

Blocked airflow, dirty coils or seized safety valves can reduce efficiency, increase electricity consumption and place unnecessary strain on the compressor.

Operating the PTR and ECV valves every six months also helps prevent mineral build-up and confirms they continue to function correctly.

Important: Always follow your manufacturer's instructions when operating safety valves, as hot water will discharge during testing. If you're unsure, contact a licensed plumber.

JR 6-Month Heat Pump Health Check

Recommended Service – $99

Our professional inspection helps identify small issues before they become costly repairs.

Our technician will:

  • Inspect the complete heat pump system.
  • Check for leaks or corrosion.
  • Test the PTR valve.
  • Test the ECV (where fitted).
  • Inspect electrical wiring and connections.
  • Check controller operation and settings.
  • Inspect airflow around the outdoor unit.
  • Check the evaporator coil for blockage or contamination.
  • Inspect the condensate drain.
  • Listen for abnormal compressor or fan operation.
  • Confirm correct heating performance.
  • Identify components showing signs of wear.

Service Price: $99

Routine inspections help maintain efficiency, reduce energy consumption and minimise the risk of unexpected breakdowns.

Recommended 5-Year Major Service

Current Price: $449

Like any major appliance, heat pump hot water systems benefit from scheduled component replacement and servicing.

Our comprehensive 5-Year Service includes:

  • Replacement of the sacrificial anode (where fitted).
  • Replacement of the Pressure & Temperature Relief (PTR) Valve.
  • Replacement of the Expansion Control Valve (ECV).
  • Full inspection of the storage tank and heat pump unit.
  • Electrical safety testing.
  • Inspection of wiring and controls.
  • Cleaning of the evaporator coil (where required).
  • Inspection of fan and compressor operation.
  • Inspection of condensate drainage.
  • Leak and corrosion inspection.
  • Operational performance testing.

Why These Components Matter

Sacrificial Anode

Most vitreous enamel-lined heat pump storage tanks contain a sacrificial anode.

The anode corrodes instead of the steel tank, protecting it from internal rust.

Replacing the anode at the recommended interval can significantly extend the life of your storage tank.

Pressure & Temperature Relief (PTR) Valve

The PTR valve protects the storage tank from excessive pressure and temperature.

Over time, mineral deposits may prevent the valve from operating correctly, making regular testing and replacement essential.

Expansion Control Valve (ECV)

Where fitted, the ECV controls pressure created as water expands during heating.

Maintaining the ECV helps protect both the storage tank and your home's plumbing system.

Airflow & Evaporator Coil

Unlike conventional electric systems, heat pumps rely on airflow across the evaporator coil to extract heat from the surrounding air.

Restricted airflow caused by leaves, dust or debris can:

  • Reduce efficiency.
  • Increase running costs.
  • Extend heating times.
  • Place additional strain on the compressor.

Keeping the unit clean helps maintain peak performance.

If Your Heat Pump Isn't Working

Before arranging a service, check the following:

  • Ensure power is switched on.
  • Check the circuit breaker and safety switch (RCD).
  • Confirm the isolator near the unit is turned on.
  • Check the controller for any fault or error codes.
  • Ensure the air inlet and outlet are unobstructed.
  • Remove any leaves or debris around the unit.
  • Check for visible water leaks.
  • Confirm the condensate drain is not blocked.
  • Listen for unusual noises from the fan or compressor.
  • Allow sufficient recovery time after heavy hot water usage.

If your system is still not producing hot water or is displaying fault codes, contact JR Gas & Water for professional diagnosis and repair.

General Signs Your System May Need Attention

Arrange a service if you notice:

  • Little or no hot water.
  • Unusual fan or compressor noises.
  • Error codes on the controller.
  • Constant water leaking.
  • Reduced heating performance.
  • Higher than normal electricity usage.
  • Water taking much longer to heat.
  • Visible corrosion.
  • Repeated electrical trips.
  • Restricted airflow due to dirt or debris.

Early servicing can often prevent more expensive repairs and prolong the life of your system.

Protect Your Warranty & Maximise System Life

Routine maintenance helps keep your heat pump operating safely, efficiently and reliably.

Following the manufacturer's recommended maintenance schedule can also assist in maintaining warranty coverage.

Failure to maintain your system may result in:

  • Reduced energy efficiency.
  • Increased electricity costs.
  • Premature tank corrosion.
  • Compressor strain.
  • Shortened system lifespan.
  • Unexpected breakdowns.
  • Possible reduction or loss of manufacturer warranty, depending on the manufacturer's maintenance requirements.

Regular preventative maintenance is one of the best ways to protect your investment and ensure your heat pump continues delivering efficient hot water for many years.

Please note: Maintenance requirements vary between manufacturers and models. Always refer to your owner's manual for the maintenance schedule applicable to your heat pump hot water system.

Estimated annual savings are calculated by comparing the heat pump’s energy efficiency (measured as COP – Coefficient of Performance) against a standard electric hot water system with a COP of 1.0. For example, if a heat pump has a COP of 4.0, it uses 75% less electricity to deliver the same amount of hot water.

Savings are based on average household usage for a family of five on Tariff 11 (general usage tariff), using manufacturer-stated COP values. The higher the COP, the greater the energy savings.

Bonus savings: When paired with a solar PV system, energy costs can drop even further — with some households seeing up to 50% additional savings, especially when the heat pump runs during solar generation times.

Disclaimer:

All estimated savings are based on manufacturer-provided COP values and standard usage assumptions (e.g. a family of five on Tariff 11). These figures are intended as a general guide to help compare different hot water units and technologies. Actual savings may vary depending on your household’s usage, energy rates, and installation conditions. We recommend conducting your own research or consulting an energy advisor to assess what’s best for your specific setup.
