    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.

STIEBEL ELTRON HEAT PUMP INSTALLATION

Stiebel Eltron SHP-O 300 Plus 3HR Free Power Ready Installation Brisbane & Gold Coast

JR Gas & Water supplies and professionally installs the Stiebel Eltron SHP-O 300 Plus 3HR Free Power Ready heat pump hot water system across Brisbane and the Gold Coast, with installation options for suitable replacements, electric-to-heat-pump upgrades and new hot water installations.

The SHP-O 300 Plus combines a 300 litre storage cylinder with heat pump technology that transfers heat from the surrounding air into the stored water. It is designed for households wanting to reduce the electricity required for water heating while retaining a substantial volume of hot water for use later in the day.

JR's 3HR Free Power Ready approach adds an installation and operating strategy around the product. Where the property, electricity plan and system settings allow, heating can be planned around daytime electricity, solar PV production and an applicable free-power period rather than simply allowing an older electric tank to heat whenever power is available.

JR installs across Greater Brisbane, the Gold Coast, Logan, Ipswich, Redlands, Moreton Bay, Scenic Rim and surrounding eligible South East Queensland areas.

Stiebel Eltron SHP-O 300 Plus installation at a glance: This is a 300L integrated heat pump hot water system with WiFi-enabled MyStiebel control, app-based timer functionality, solar PV compatibility and a manufacturer-rated COP of 4.21. JR Gas & Water can supply and install it across Brisbane and the Gold Coast and configure the installation around suitable daytime operation and 3 hour free power planning. Final suitability depends on household demand, airflow, location, drainage, plumbing, electrical supply and the electricity plan being used.

Who Is the Stiebel Eltron SHP-O 300 Plus Best For?

Families Wanting 300L Storage

The integrated 300L tank stores heated water for later use, making the SHP-O 300 Plus suitable for households needing more stored capacity than smaller heat pump systems can provide.

Homes Reducing Electric Hot Water Use

Instead of relying primarily on resistance heating, the heat pump transfers ambient heat into the water. This can substantially reduce electricity consumption compared with conventional electric storage when the system is correctly installed and operated.

Daytime & Solar-Focused Homes

The MyStiebel App provides timer functionality, and Stiebel Eltron lists the system as solar PV compatible. That makes it well suited to homes wanting to move more hot water heating into useful daytime periods.

PRODUCT SUITABILITY

Is the Stiebel Eltron SHP-O 300 Plus Right for My Home?

A Good Choice If...

You want a premium 300L heat pump, lower electricity demand than conventional resistance storage, app-based scheduling, solar PV compatibility and enough physical space for an integrated heat pump installation.

Consider Another Option If...

Your priority is the lowest possible upfront replacement cost, the installation position cannot provide suitable airflow or service clearances, or a smaller household simply does not need 300L of stored hot water.

JR Should Check First If...

The unit will be installed indoors, relocated, positioned close to bedrooms or boundaries, converted from gas, placed in a restricted area, or requires changes to the existing electrical circuit, drainage or plumbing.

How Many People Does the Stiebel Eltron SHP-O 300 Plus Suit?

JR's current product sizing guidance lists the 300L SHP-O for households of up to 6 occupants. Actual suitability still depends on how the household uses hot water rather than occupant count alone.

A home with long showers, multiple bathrooms operating close together, large baths or unusually high morning and evening demand may use substantially more hot water than another six-person household. The operating schedule also matters when the goal is to concentrate heating into a daytime or free-power window.

For 3HR Free Power Ready planning, JR should consider both storage capacity and recovery strategy. The aim is to heat enough water during favourable periods to carry the household through later demand without unnecessarily forcing additional heating during paid electricity periods.

How Does the Stiebel Eltron SHP-O 300 Plus Work?

Input: The heat pump draws heat energy from the surrounding air and uses electricity to operate the refrigeration circuit.

Operation: That captured heat is transferred into the water stored in the integrated 300L cylinder. An auxiliary electric heater is also incorporated into the system for operating conditions or functions that require it.

Result: The home receives a stored supply of hot water that can be heated during selected periods and used later for showers, bathrooms, kitchen and laundry demand.

This storage-based design is especially useful for daytime energy strategies. Instead of trying to make hot water at exactly the moment it is used, the system can store thermal energy as hot water and carry that energy into the evening or following morning.

INSTALLATION REQUIREMENTS

What Is Required to Install the Stiebel Eltron SHP-O 300 Plus?

Heat pump hot water systems are more location-sensitive than a basic electric storage cylinder because the heat pump needs access to ambient air and produces condensate during operation. The installation position can therefore affect efficiency, noise, serviceability and long-term performance.

Suitable location with adequate airflow
Manufacturer clearances around the unit
Stable and suitable support base
Compliant cold and hot water connections
Correct pressure-control and relief valves
Suitable relief and condensate drainage
Appropriate electrical supply and isolation
Safe access for installation and future servicing
Consideration of nearby bedrooms and boundaries
Licensed plumbing and electrical work where required

A straightforward heat-pump-for-heat-pump replacement can be very different from relocating the unit or replacing gas or conventional electric storage. JR assesses the existing services and installation position before confirming the appropriate installation pathway.

What's Included With Stiebel Eltron SHP-O 300 Plus Installation?

Standard Replacement

The applicable JR installation package can cover supply of the genuine system and the plumbing work required for the selected replacement scope. Existing-system removal, new valves, pipework and other works depend on the package chosen above.

Compliance & Commissioning

The installed system is connected, tested and commissioned for operation. Relevant plumbing and electrical work is completed by appropriately licensed trades for the work involved.

Possible Additional Work

Electrical modifications, a new circuit, relocation, extra pipework, drainage changes, valve upgrades, base work, difficult access or unusual site requirements may increase the scope.

Use the live package selector above for the inclusions attached to the exact installation option being purchased.

How Much Does Stiebel Eltron SHP-O 300 Plus Installation Cost?

Current supplied-and-installed pricing is shown in the live product package selector above rather than being repeated as a fixed SEO price here.

The final Stiebel Eltron SHP-O 300 Plus installation cost in Brisbane or the Gold Coast can change according to the selected package, existing hot water system, valve condition, electrical work, location, access, drainage, pipework, system removal and whether the new unit can remain in the current position.

An uncomplicated replacement of a suitable existing heat pump is very different from converting a gas system, relocating the cylinder or creating a new electrical supply. Where the standard online package does not match the property, JR can assess the installation before the work proceeds.

3HR FREE POWER READY

How Does the SHP-O 300 Plus Work With 3 Hour Free Power?

The 3HR Free Power Ready approach is about combining heat pump efficiency with better timing. Stiebel Eltron's current technical information confirms that the MyStiebel App can be used to align heat pump operating time with a power supply or demand period and to set operating hours.

Where the home's electricity plan provides an eligible free daytime period, the operating schedule can therefore be planned to favour that window where practical. Homes with solar PV may also use daytime operation to make better use of self-generated electricity.

The aim is not to promise that every litre of hot water will always be produced free of charge. Actual results depend on electricity-plan rules, smart-meter eligibility, household demand, system settings, weather, solar production and whether additional heating is needed outside the preferred period.

A well-planned installation gives the household the ability to use the opportunity intelligently rather than simply replacing the old tank and leaving its operating pattern unchanged.

Why Choose a Heat Pump for 3 Hour Free Power Instead of Only a Timer?

A timer changes when a conventional electric hot water system can heat. It does not by itself change the basic resistance-heating method used by the tank.

The SHP-O 300 Plus approaches the problem differently. Heat pump technology is designed to reduce the amount of electrical energy required to move heat into the water, while scheduling can then influence when that electricity is consumed.

In simple terms: a timer can help shift electricity use, while a heat pump can reduce electricity demand as well as shift operating time. That is why an ageing electric tank should often be compared against a heat pump upgrade before money is spent only on control hardware.

BRISBANE INSTALLATION

Stiebel Eltron SHP-O 300 Plus Installation Brisbane

JR Gas & Water supplies and installs the Stiebel Eltron SHP-O 300 Plus in Brisbane for suitable heat pump replacements, electric storage upgrades and new installations. A Brisbane install starts with confirming that the 300L capacity, installation position and electrical arrangement suit the property.

For a Stiebel Eltron SHP-O 300 Plus replacement in Brisbane, location is particularly important. The unit needs appropriate airflow, drainage and service access, and the position should be considered in relation to bedrooms, entertaining areas and neighbouring properties.

Homes in Brisbane, Logan, Ipswich, Redlands and Moreton Bay upgrading from conventional electric storage may also need plumbing or electrical alterations rather than a simple like-for-like swap. JR's package selector above is designed to separate straightforward installations from jobs requiring additional work.

GOLD COAST INSTALLATION

Stiebel Eltron SHP-O 300 Plus Installation Gold Coast

JR Gas & Water also supplies and installs the Stiebel Eltron SHP-O 300 Plus across the Gold Coast for households wanting a premium heat pump with substantial stored capacity and smart daytime operating options.

Gold Coast properties can vary significantly in side access, external plant space, apartment or townhouse constraints and proximity to neighbouring living areas. That makes system positioning an important part of the installation rather than something that should be decided only by where the old cylinder happened to sit.

For a Stiebel Eltron SHP-O 300 Plus supplied and installed on the Gold Coast, JR considers the existing hot water service, available airflow, drainage, electrical supply and practical servicing access before confirming the installation pathway.

Can the Stiebel Eltron SHP-O 300 Plus Replace My Existing Hot Water System?

Replacing an Existing Heat Pump

This can be the simplest pathway when the existing position, base, drainage, plumbing and electrical services are suitable. Pipework and connection positions still need to be checked.

Replacing Electric Storage

The SHP-O 300 Plus can be a logical efficiency upgrade from conventional electric storage, but the new heat pump's airflow, physical dimensions, drainage and electrical requirements must be assessed.

Replacing a Different Brand

Changing brand is possible where the site suits the Stiebel Eltron. It should not be treated as an identical replacement because connections, dimensions and clearances can differ.

Changing From Gas

A gas-to-heat-pump conversion changes the property's energy source for hot water and can require new electrical work plus plumbing alterations.

Relocating the System

Relocation may improve airflow, noise separation or access, but usually increases plumbing, drainage and electrical scope.

Indoor Installation

Indoor installations need specific assessment against Stiebel Eltron's ventilation, room-volume, clearance and installation requirements and should not be assumed suitable from photographs alone.

Which Stiebel Eltron SHP-O Variant Do I Need?

SHP-O 300 Plus

This is the model covered on this page. It provides 300L nominal storage, MyStiebel connectivity and the SHP-O Plus efficiency platform.

SHP-O 200 Plus

The same Plus family is also available with 200L nominal capacity. A smaller cylinder may suit lower-demand homes, but sizing should be based on actual usage rather than choosing the cheaper or smaller unit automatically.

SHP-O 301 Premium

The 300L Premium variant adds active defrost and is specified by Stiebel Eltron for climate zones including very cold climates. Whether that additional capability is relevant depends on the installation location and application.

How Efficient Is the Stiebel Eltron SHP-O 300 Plus?

Stiebel Eltron's current technical data lists the SHP-O 300 Plus at a COP of 4.21 under EN16147 / A20 test conditions and an A+ energy-efficiency class. COP is a laboratory performance measure rather than a promise that every household will achieve exactly the same result.

Real electricity use changes with ambient conditions, incoming water temperature, hot water demand, selected temperature, operating schedule and use of the auxiliary heater. The system's advantage is that its primary heating process transfers heat from the surrounding air rather than creating all of the heat through direct electrical resistance.

For a 3HR Free Power Ready installation, efficiency and timing work together: reduce the electricity required to make hot water, then aim to consume that electricity during the most favourable available period.

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.

  • 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.

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.
