AUSTRALIAN-MADE HEAT PUMP HOT WATER

Dux EcoSmart 285L Heat Pump Installation Brisbane & Gold Coast

JR Gas & Water supplies and installs the current-generation Dux EcoSmart 285L Heat Pump across eligible Brisbane, Gold Coast and surrounding South East Queensland service areas.

The current EcoSmart 285L range uses model numbers 300DHC25 and 300DHC25P. It combines a large mains-pressure storage cylinder with an integrated air-source heat pump, low-GWP R290 refrigerant, Smart Life app control, timer scheduling, a backup electric element and multiple operating modes.

Dux markets this model as the 285L EcoSmart. Its current technical manual lists an actual storage capacity of 287 litres, reflecting the difference between the marketed capacity class and the technical cylinder specification.

Dux EcoSmart 285L at a glance: current models 300DHC25 and 300DHC25P provide 287L technical storage capacity, a 2.5kW heat-pump heating output, COP of 4.63 under Dux's stated test conditions, approximately 54L/hour heat-pump-only recovery at 20°C ambient, R290 refrigerant, app and touchscreen control, outdoor installation and hardwired or plug-in electrical variants.

PRODUCT AT A GLANCE

Dux EcoSmart 285L Heat Pump Hot Water

Large Storage Capacity

Marketed as 285L, with Dux's current technical documentation listing 287L actual storage capacity.

COP 4.63

Dux publishes a coefficient of performance of 4.63 at 20°C ambient while heating water from 20°C to 60°C.

Smart Control

Smart Life app control, onboard touchscreen, operating modes and timer scheduling provide flexible control over when the system heats.

Made in Australia

The current third-generation EcoSmart range is designed and manufactured in Australia.

WHO IT SUITS

Is the Dux EcoSmart 285L Right for Your Home?

Dux positions the EcoSmart 285L for larger families and homes with greater stored hot water demand, particularly where an older electric storage water heater is being replaced with a lower-energy alternative.

Larger Households

The larger cylinder provides more stored hot water than the EcoSmart 200L and is intended for households where the smaller model may not provide enough reserve.

Electric Storage Replacement

Dux specifically designed the 285L model with the same nominal 620mm tank diameter as its Proflo 250L and 315L electric storage systems, which can help with suitable replacement footprints.

Solar PV Homes

Timer scheduling through the controller or Smart Life app can be used to target periods when excess rooftop solar generation may be available.

JR Installer Verdict: capacity is only one part of heat-pump selection. The outdoor location, airflow, service clearances, electrical connection, drainage and household recovery requirements should all suit the EcoSmart before installation is booked.

HOW IT WORKS

How Does the Dux EcoSmart 285L Heat Pump Work?

A heat pump uses electricity differently from a conventional resistance-only electric storage water heater. Instead of relying primarily on an electric element to create heat, the EcoSmart transfers heat from the surrounding air into the stored water.

Heat Is Collected From Air

The refrigeration circuit absorbs heat energy from the outdoor ambient air.

Heat Is Transferred to Water

Dux's patented dual-wall heating coil transfers heat into the stored water inside the cylinder.

Element Provides Backup

An electric element can assist during Boost operation and provides backup support in very low ambient conditions or selected operating situations.

The heat pump remains an electric appliance. Its efficiency advantage comes from moving ambient heat into the water rather than producing the full heating requirement through resistance heating alone.

ENERGY EFFICIENCY

How Efficient Is the Dux EcoSmart 285L?

Dux currently publishes a COP of 4.63 for the 300DHC25 / 300DHC25P under test conditions of 20°C ambient air while heating water from 20°C to 60°C.

A COP above 4 means that under those stated test conditions the heat-pump cycle delivers substantially more heat energy into the water than the electrical energy consumed by the heat-pump system.

COP 4.63

Published under Dux's specified 20°C ambient and 20°C-to-60°C water-heating test conditions.

Up to 71.6% Less Energy

Dux states the 285L model can use up to 71.6% less energy than a comparable standard electric water heater under its approved modelling conditions.

Real Usage Varies

Actual household energy consumption depends on hot water use, ambient conditions, operating mode, tariff, scheduling and how often the backup element operates.

The 71.6% figure is not a guaranteed bill reduction. Dux bases it on Australian Government-approved TRNSYS modelling for a medium load in Zone 3 when replacing a similar-size electric water heater.

RECOVERY PERFORMANCE

How Fast Does the EcoSmart 285L Reheat?

Dux publishes separate recovery figures for normal heat-pump operation and single-shot Boost operation.

Heat Pump Only Approximately 54L/hour at 20°C ambient
Hardwired Boost Up to approximately 93L/hour using the heat pump plus 1.8kW backup element
Plug-In Boost Up to approximately 80L/hour using the heat pump plus 1.2kW backup element
Published Test Conditions 20°C ambient air, 20°C cold-water inlet and 60°C hot-water outlet
Heat-pump-only full reheating is just over five hours under Dux's published test conditions. Real recovery changes with ambient temperature, incoming water temperature and the operating mode selected.

HARDWIRED OR PLUG-IN

Dux EcoSmart 300DHC25 vs 300DHC25P

The current 285L EcoSmart is available in two primary electrical variants. The heat-pump refrigeration system is shared, but the electrical input and backup-element capacity differ.

Specification 300DHC25 300DHC25P
Connection Type Hardwired Plug-in variant
Technical Storage Capacity 287L 287L
Rated Energy Input 2.6kW 2.0kW
Maximum Current 12.6A 10A
Backup Element 1.8kW 1.2kW
Heat-Pump-Only Recovery 54L/hr 54L/hr
Single-Shot Boost Recovery Up to 93L/hr Up to 80L/hr
Best Direction Higher backup-element capacity where the electrical installation suits the hardwired model. Lower-current plug-in pathway where the complete electrical installation suits the P model.
The plug-in version does not have a weaker heat pump. Both use the same published 2.5kW heat-pump heating output. The key electrical difference is the backup-element size and maximum current.

SMART CONTROL

Smart Life App, Scheduling & Operating Modes

The current EcoSmart combines an onboard touchscreen controller with Smart Life app connectivity, allowing operating modes and schedules to be managed at the unit or remotely where Wi-Fi is available.

ECO Mode

The primary normal operating mode. Dux states the heat pump heats the cylinder to 60°C during each heating cycle.

Boost Mode

A one-shot recovery mode where the heat pump and backup element operate together before the system returns to ECO operation.

Holiday Mode

Reduces normal heating while maintaining the tank at a low temperature to protect against freezing during extended absence.

Rescue Function

An app-accessible temporary mode designed to operate the electric element if the heat-pump heating system has a fault.

PV scheduling: multiple timer schedules can be configured so the heat pump operates during preferred periods, including times when excess rooftop solar production may be available.

OUTDOOR INSTALLATION

Where Can the EcoSmart 285L Be Installed?

Dux's current installation manual specifies the EcoSmart heat pump for outdoor installation only. The unit needs unrestricted airflow around the heat-pump section and access for future servicing.

Fan Side Clearance

Dux specifies at least 500mm minimum clearance on the fan side to allow airflow.

Evaporator Side

A minimum of 300mm is required on the evaporator side.

Top & Rear

Minimum clearance is 300mm above and 50mm behind, with additional clearance preferred for servicing and anode access.

Service access matters. Dux recommends additional clearance beyond the minimum where possible and requires the electrical cover, refrigeration components, controller, relief valve and sacrificial anodes to remain accessible.

Avoid squeezing the unit into a poorly ventilated enclosure. Dux requires adequate unobstructed airflow around the water heater and advises against locating it near bedrooms or neighbouring bedrooms because the heat pump may operate at night.

INSTALLATION REQUIREMENTS

What Is Required to Install a Dux EcoSmart 285L?

Outdoor installation position with the manufacturer's required airflow clearances.
Flat solid supporting surface capable of carrying the filled water heater safely.
Suitable mains-water connection with pressure reduction where incoming pressure can exceed Dux's permitted limit.
Correct PTR valve and drain arrangement with the drain remaining open to atmosphere.
Condensate drainage arranged so normal heat-pump condensate can discharge appropriately.
Suitable single-phase electrical supply matched to the hardwired or plug-in model being installed.
Service and anode access retained around and above the system.
Licensed installation and commissioning in accordance with current Dux instructions and applicable requirements.
Safe tray requirements depend on the site. Dux specifies that a properly drained safe tray is required where water spillage could cause property damage rather than as an unconditional requirement for every installation.

PRESSURE & DRAINAGE

PTR Valve, Water Pressure & Condensate

A heat pump is still a pressurised storage water heater, so the normal storage-system safety and drainage requirements remain important.

1000kPa PTR Valve

Dux specifies a 1000kPa / 10kW pressure-and-temperature relief valve installed directly into the designated relief-valve connection.

800kPa Supply Limit

The current manual allows direct connection to water supply pressure up to 800kPa. A pressure-reducing valve is required where supply pressure can exceed or fluctuate above this level.

Normal Drainage

PTR discharge during heating and condensate from heat-pump operation both need suitable drainage pathways.

Never cap or block the PTR drain. Dux requires the PTR drain line to fall continuously and remain open to atmosphere.

200L VS 285L

Dux EcoSmart 200L vs 285L

Specification EcoSmart 200L EcoSmart 285L
Models 200DHC25 / 200DHC25P 300DHC25 / 300DHC25P
Technical Storage Capacity 202.5L 287L
COP at Published Conditions 4.23 4.63
Heat-Pump-Only Recovery 53L/hr 54L/hr
Height 1580mm 2005mm
Diameter 620mm 620mm
Net Weight 90kg 125kg
Best Direction Lower stored-water demand and tighter height restrictions. Larger households or homes wanting a greater stored hot-water reserve.
The larger model is mainly about stored capacity rather than dramatically faster heat-pump recovery. Published heat-pump-only recovery is 53L/hr for the 200 and 54L/hr for the 285 under the same test conditions.

REPLACEMENT COMPATIBILITY

Can the EcoSmart 285L Replace an Electric Storage System?

Yes, and this is one of the clearest applications Dux identifies for the model. The current 285L EcoSmart uses the same nominal 620mm tank diameter as Dux Proflo 250L and 315L electric storage water heaters.

Proflo 250L Replacement

The shared tank diameter may help where the existing base position already suits a 620mm Dux electric storage cylinder.

Proflo 315L Replacement

The same nominal diameter can also simplify footprint assessment when replacing a suitable Dux 315L electric storage system.

Height Still Changes

The complete EcoSmart heat pump is 2005mm high, so overhead clearance, airflow and service access still need to be checked even when the base footprint aligns.

A matching diameter does not make every replacement like-for-like. Heat pumps introduce airflow, condensate, electrical, clearance and servicing requirements that do not apply in the same way to a standard resistance storage tank.

SOLAR PV & TARIFFS

Can the EcoSmart 285L Run With Solar PV?

Yes. The EcoSmart's controller and Smart Life app allow timer schedules to be configured around preferred operating periods.

Daytime PV Scheduling

Homes with rooftop solar can schedule normal heating toward periods when excess solar generation is commonly available.

Time-of-Use Tariffs

Scheduling can also be used to target preferred electricity tariff periods where the household's hot water pattern allows it.

Stored Hot Water

The large cylinder acts as thermal storage, allowing water heated during a scheduled period to be used later.

Scheduling should still preserve enough hot water for the household. Aggressive timer settings that do not match usage can reduce available stored hot water before the next heating period.

GOVERNMENT INCENTIVES

Is the Dux EcoSmart 285L Eligible for STCs?

Dux currently lists the EcoSmart 285L as eligible for Small-scale Technology Certificates (STCs), subject to the system, installation, postcode, installation year and current scheme requirements.

Certificate values reduce over time and should not be hardcoded into long-form product content. The current installed selector or quote should be used to confirm any incentive already applied to the installation price.

Rebate eligibility is not automatic for every job. Government programs, certificate values and eligibility conditions can change, so the live installation price should be checked at the time of purchase.

BRISBANE INSTALLATION

Dux EcoSmart 285L Heat Pump Installation Brisbane

JR Gas & Water installs the Dux EcoSmart 285L across eligible Brisbane service areas where the property has a suitable outdoor position, adequate airflow, drainage and electrical connection.

Dux's published COP and recovery figures are measured at 20°C ambient, which is useful context for South East Queensland but should not be treated as a guarantee of identical performance every day. Actual efficiency and recovery change as ambient and inlet-water temperatures change.

For Brisbane homes replacing a 250L or 315L electric storage unit, the EcoSmart's 620mm tank diameter can be helpful when assessing the existing footprint, but the greater overall height and heat-pump airflow clearances must still be allowed for.

GOLD COAST INSTALLATION

Dux EcoSmart 285L Heat Pump Installation Gold Coast

JR Gas & Water also provides Dux EcoSmart 285L installation across eligible Gold Coast service areas for homes where the outdoor position and household hot water demand suit the system.

Properties with tight side access, boundary locations or compact outdoor service areas need particular attention to the EcoSmart's fan-side, evaporator-side and top clearances. The unit also needs future access to the refrigeration components, controller, PTR valve and sacrificial anodes.

Where the available space cannot provide the manufacturer's required airflow and service access, another heat-pump size or hot water technology may provide a more practical installation pathway.

MAINTENANCE & OWNERSHIP

Dux EcoSmart 285L Maintenance

The EcoSmart combines a storage cylinder, refrigeration system, electric backup element, sacrificial anodes, PTR valve, fan and electronic controls. Ongoing ownership therefore involves more than treating it like a basic electric resistance tank.

PTR Valve

Dux instructs owners to operate the PTR easing lever at least once every six months and requires the discharge path to remain unobstructed.

Airflow

The fan and evaporator area should remain free of stored items or obstructions that interfere with the required airflow.

Anodes & Servicing

The installation should preserve top and service access so protective anodes and major components can be maintained when required.

Some PTR discharge during heating can be normal. Continuous or abnormal discharge can indicate excessive pressure, a valve issue or another fault and should be investigated.

Does it really use 71.6% less energy?

Dux states that the 285L model can use up to 71.6% less energy than a similar standard electric water heater under its specified Australian Government-approved modelling conditions. It is not a guaranteed household bill saving.

How quickly does the Dux EcoSmart 285L heat water?

Dux publishes approximately 54L/hour in heat-pump-only operation at 20°C ambient with 20°C inlet water heated to 60°C. Under those test conditions, a full reheating cycle takes just over five hours.

What is the Boost recovery rate?

The hardwired 300DHC25 can reach approximately 93L/hour during single-shot Boost under Dux's test conditions. The plug-in 300DHC25P is listed at approximately 80L/hour because it uses a smaller backup element.

What is the difference between the hardwired and plug-in versions?

The hardwired 300DHC25 has a 2.6kW rated energy input, 12.6A maximum current and 1.8kW backup element. The plug-in 300DHC25P is rated at 2.0kW, 10A and uses a 1.2kW backup element.

Does the plug-in version have a smaller heat pump?

No. Dux publishes the same 2.5kW heat-pump heating output and 54L/hour heat-pump-only recovery for both variants. The difference is primarily the electrical connection and backup-element capacity.

Does the EcoSmart 285L have Wi-Fi?

Yes. The current-generation EcoSmart supports the Smart Life app where the water heater has suitable power and Wi-Fi reception at its installation location.

Can I schedule the Dux heat pump around solar power?

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.

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. 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.
