    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.

FAST-RECOVERY HEAT PUMP HOT WATER

Dux EcoSmart Pro-Series 270L Installation Brisbane & Gold Coast

JR Gas & Water supplies and installs the Dux EcoSmart Pro-Series 270L Heat Pump across eligible Brisbane, Gold Coast and surrounding South East Queensland service areas.

The EcoSmart Pro-Series 270L is Dux's high-recovery heat pump option for homes wanting a large stored hot water reserve with significantly lower electricity use than a conventional resistance-only electric storage water heater.

The current range uses model numbers 270DHB36 and 270DHB36P and combines a 270L cylinder, 3.6kW heat-pump heating capacity, R290 refrigerant, an external copper wraparound condenser, active defrost, a tank-mounted controller and hardwired or plug-in electrical options.

Dux EcoSmart Pro-Series 270L at a glance: 270L storage, COP 4.7 under Dux's stated test conditions, approximately 77L/hour heat-pump-only recovery, R290 refrigerant, 2010mm overall height, 640mm nominal diameter and suitability for households of up to 7 people on a continuous tariff under Dux's sizing guidance. The hardwired and plug-in versions use the same 3.6kW heat-pump heating capacity but have different backup-element and electrical specifications.

PRODUCT AT A GLANCE

Dux EcoSmart Pro-Series 270L Heat Pump

270L Storage

A large mains-pressure stored-water capacity intended for homes with stronger daily hot water demand.

77L/Hour Recovery

Dux publishes approximately 77 litres per hour using the heat pump alone under its stated 20°C test conditions.

COP 4.7

High published heat-pump efficiency under Dux's nominated ambient and water-temperature test conditions.

Up to 7 People

Dux positions the Pro-Series 270L for households of up to seven people when used on a continuous tariff.

WHO IT SUITS

Is the EcoSmart Pro-Series 270L Right for Your Home?

The Pro-Series 270L is aimed at households that need both large stored capacity and faster heat-pump recovery. It can be particularly relevant when replacing a larger electric storage system and reducing electricity use is a priority.

Larger Households

Dux sizes the system for up to seven occupants on a continuous tariff, subject to actual shower lengths, fixture flow rates and household usage patterns.

High Daily Hot Water Use

The 3.6kW heat-pump heating capacity and 77L/hour published recovery make it better suited to stronger recovery requirements than slower heat-pump models.

Solar PV & Flexible Tariffs

The tank-mounted controller includes scheduling, allowing heating periods to be aligned with preferred tariff or rooftop-solar periods where practical.

JR Installer Verdict: the Pro-Series is most compelling where the household will actually benefit from the faster recovery. A smaller or lower-output heat pump may still suit homes with lighter daily demand.

HOW IT WORKS

How Does the Dux EcoSmart Pro-Series Work?

The EcoSmart Pro-Series is an integrated air-source heat pump. It extracts heat from the outdoor air and transfers that energy into the stored water rather than relying primarily on a conventional electric element.

Air Provides Heat

The refrigeration circuit collects heat energy from the surrounding outdoor air.

Compressor Raises the Temperature

The R290 refrigeration cycle increases the useful heat level before transferring it into the water cylinder.

Copper Coil Transfers Heat

The external copper wraparound condenser transfers heat through the cylinder wall rather than sitting directly in the stored water.

The external condenser is one of the Pro-Series design differences. Dux states that the wraparound copper heat exchanger makes the system suitable for a broad range of Australian water qualities because the refrigerant-side heat exchanger does not directly contact the stored water.

EFFICIENCY

How Efficient Is the EcoSmart Pro-Series 270L?

Dux currently publishes a COP of 4.7 for the Pro-Series 270L at 20°C ambient while heating water from 20°C to 60°C.

COP 4.7

Under the specified test condition, the heat pump delivers substantially more thermal energy into the water than the electrical energy consumed by the refrigeration system.

Up to 75% Less Energy

Dux's current Pro-Series material states that the system can use up to 75% less energy than a standard electric water heater under the manufacturer's comparison conditions.

Real Usage Varies

Actual household energy use depends on hot water demand, climate, inlet-water temperature, operating mode, tariff and element operation.

Efficiency figures are test-condition comparisons, not guaranteed bill reductions. Electricity pricing and household use can substantially change the financial result even where the appliance itself operates efficiently.

FAST RECOVERY

How Fast Does the Pro-Series 270L Reheat?

Fast heat-pump recovery is the defining feature of the Pro-Series range.

Heat Pump Only Approximately 77L/hour at 20°C ambient with water heated from 20°C to 60°C
Approximate Full-Tank Heat-Up Approximately 3.5 hours under Dux's stated test conditions
Hardwired + Element Approximately 129L/hour in the manufacturer's published combined heating reference
Plug-In + Element Approximately 99L/hour in the manufacturer's published combined heating reference
Real recovery changes with conditions. Lower ambient temperatures, colder inlet water and the amount of hot water remaining in the tank can change the time required to restore a full cylinder.

HARDWIRED OR PLUG-IN

270DHB36 vs 270DHB36P

The current Pro-Series is available in both hardwired and plug-in versions. Both use the same 270L cylinder and 3.6kW rated heat-pump heating capacity, but their electrical input and backup-element size differ.

Specification 270DHB36 270DHB36P
Connection Type Hardwired Plug-in
Storage Capacity 270L 270L
Heat-Pump Heating Capacity 3.6kW 3.6kW
Rated Power Input 3.48kW 2.1kW
Rated Current Input 14.5A 8.8A
Backup Element 2.4kW 1.0kW
Heat-Pump Recovery 77L/hr 77L/hr
Combined Heating Reference Approximately 129L/hr Approximately 99L/hr
Electrical Direction Higher element capacity and hardwired connection. Supplied with a 3m power lead for connection to a suitable 10A GPO.
The plug-in version does not use a smaller heat pump. The 3.6kW refrigeration heating capacity is the same. The main difference is the smaller backup element and lower electrical input of the plug-in model.

OUTDOOR INSTALLATION

Where Can the EcoSmart Pro-Series 270L Be Installed?

Dux specifies the EcoSmart Pro-Series for outdoor installation only. The heat-pump section needs clear airflow and the appliance must remain accessible for servicing.

Air Inlet Clearance

Dux's current installation diagram requires at least approximately 350mm of unobstructed space on the air-inlet side.

Air Outlet Clearance

The fan discharge side requires substantially more open space, with approximately 1000mm shown in the current installation diagram.

Service Access

The electrical cover, refrigeration components, controller, PTR valve and sacrificial anodes need to remain accessible without requiring a ladder or scaffold.

Do not squeeze the heat pump into a poorly ventilated enclosure. Dux requires unobstructed airflow and specifies a minimum installation-space volume where barriers surround the system.

Bedroom placement matters. Dux advises avoiding installation immediately beside bedrooms or neighbouring bedrooms because the heat pump can operate at night.

DRAINAGE & PRESSURE

Condensate, PTR Drainage & Water Pressure

The Pro-Series produces normal refrigeration condensate as well as the normal pressure-relief discharge associated with a storage water heater. These require separate correctly installed drainage arrangements.

Condensate Drain

Dux requires a drain line from the dedicated condensate point so water produced by normal heat-pump operation discharges clear of the water heater.

PTR Drain

The relief-valve drain must run continuously downward and remain separate from the condensate drain line.

800kPa Maximum Inlet

The current manual specifies a maximum inlet water pressure of 800kPa, with pressure control required where site conditions exceed the permitted level.

Never block the PTR discharge. Some relief-valve discharge during heating can be normal, but the drain pathway must remain free and correctly installed.

SOLAR PV & TARIFFS

Can the Pro-Series 270L Run With Solar PV?

Yes. The onboard controller provides scheduling that can be used to target preferred heating periods.

Daytime Solar

Where rooftop PV produces excess power during the day, timer settings can be arranged to favour those hours where they also suit household hot water requirements.

Solar Sponge Tariffs

Dux specifically positions the faster-recovery Pro-Series as a strong match for lower-cost daytime or solar-sponge electricity tariffs.

Stored Energy

The 270L cylinder stores the heated water so energy collected during a scheduled period can be used later.

Scheduling should match real usage. Restricting heating periods too aggressively can reduce the available hot water reserve before the next scheduled cycle.

ELECTRIC STORAGE REPLACEMENT

Can the Pro-Series 270L Replace My Existing Electric Water Heater?

Often yes, and Dux specifically promotes the Pro-Series as having a footprint similar to many electric water heaters it is intended to replace.

Existing Large Electric Storage

Replacing a suitable outdoor electric cylinder can be a strong pathway where the new location also provides the airflow and service clearance a heat pump requires.

Electrical Options

The availability of hardwired and plug-in models can provide flexibility when matching the new system to suitable existing electrical infrastructure.

Heat Pump Requirements Still Apply

A similar footprint does not remove the need for condensate drainage, fan clearance, service access and heat-pump airflow.

A tank swap and a heat-pump conversion are not always the same job. Even where the cylinder fits the old position, the complete installation still needs to meet the current Dux heat-pump requirements.

INSTALLATION REQUIREMENTS

What Is Required to Install the EcoSmart Pro-Series 270L?

Suitable outdoor position with unrestricted airflow and servicing access.
Flat solid supporting surface able to safely support the filled water heater.
Correct water pressure control where incoming supply conditions require it.
1000kPa PTR valve arrangement with correctly installed relief drainage.
Separate condensate drainage for normal heat-pump operation.
Suitable single-phase electrical supply matched to the hardwired or plug-in variant.
Appropriate plumbing connections without unnecessary restrictions or unsupported pipework.
Qualified installation and commissioning in accordance with current Dux instructions and applicable requirements.
Safe tray requirements are site dependent. Dux requires a properly drained safe tray where water spillage could cause property damage rather than specifying one unconditionally for every outdoor installation.

GOVERNMENT INCENTIVES

Is the Dux EcoSmart Pro-Series Eligible for STCs?

Yes. Dux currently lists the Pro-Series 270L as eligible for Small-scale Technology Certificates, subject to the approved system, installation year, postcode and current scheme requirements.

STC values reduce over time, so the long-form product page should not rely on a fixed rebate dollar value.

Use the live installation selector above for current pricing. Any applicable STC value or other incentive should be confirmed at the time of purchase rather than assumed from an older advertised figure.

JR INSTALLATION

What's Included With Dux EcoSmart Pro-Series 270L Installation?

JR's live package selector above shows the current installation options. The correct package depends on the system being replaced and whether the existing base, plumbing, valves, electrical supply and drainage can be reused compliantly.

BRISBANE INSTALLATION

Dux EcoSmart Pro-Series 270L Installation Brisbane

JR Gas & Water supplies and installs the Dux EcoSmart Pro-Series 270L across eligible Brisbane service areas where the property provides a suitable outdoor location, electrical supply, drainage and airflow.

Dux's published COP and 77L/hour recovery figures are based around 20°C ambient test conditions. Brisbane's generally mild climate can be favourable for heat-pump operation, but actual ambient temperature, humidity and inlet-water temperature vary throughout the year.

The faster-recovery Pro-Series can be particularly relevant for larger households or homes using daytime PV generation or time-of-use electricity where the tank needs to recover a meaningful amount of stored hot water inside a shorter heating window.

GOLD COAST INSTALLATION

Dux EcoSmart Pro-Series 270L Installation Gold Coast

JR Gas & Water provides Dux EcoSmart Pro-Series 270L installation across eligible Gold Coast service areas for suitable homes with adequate outdoor space and service access.

Side access, boundary clearances and nearby bedrooms are important considerations because the heat-pump fan needs unobstructed air movement and the system can operate outside normal daytime hours.

Where the existing hot water position cannot provide suitable airflow or drainage, JR can assess relocation or compare another heat-pump model before the installation pathway is selected.

MAINTENANCE

EcoSmart Pro-Series Maintenance & Ownership

The Pro-Series combines a storage cylinder, refrigeration circuit, electric backup element, sacrificial anodes, PTR valve, fan and electronic controller, so ongoing maintenance involves more than a basic resistance-only storage tank.

PTR Valve

The relief system needs to remain operational and its drain pathway must remain unobstructed.

Airflow Components

The evaporator, louvres, fan blades and grille should remain clear of dirt, vegetation and other obstructions.

Anodes & Water Quality

Dux uses sacrificial anodes to help protect the storage cylinder, with service frequency affected by local water conditions.

Dux recommends additional servicing in higher-TDS water. The current manual specifically identifies PTR replacement, anode replacement and cleaning of condensate, evaporator and fan components as service items under the applicable maintenance schedule.

WARRANTY

Dux EcoSmart Pro-Series 270L Warranty

Dux's current Pro-Series material lists:

5 Years

Tank warranty, including labour, subject to Dux's current warranty terms and conditions.

5 Years

Refrigeration components warranty including labour, subject to Dux's current warranty terms.

1 Year

Other components parts and labour under the current manufacturer warranty structure.

The Pro-Series should not be described as having a blanket seven-year manufacturer warranty. Current Dux documentation specifies five years for the tank and refrigeration components and one year for other components.

JR's live Pro-Series page currently identifies the system as eligible for JR's Lifetime Warranty program. JR-specific coverage is separate from Dux's manufacturer warranty and remains subject to JR's applicable 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.

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. JR Gas & Water services all major heat pump brands in accordance with manufacturer recommendations where applicable.

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.
