300L SPLIT-SYSTEM HEAT PUMP HOT WATER
Emerald 300L Split System Heat Pump Installation Brisbane & Gold Coast
JR Gas & Water supplies and installs the Emerald HPRX300E-1 300L Split System Hot Water Heat Pump across eligible Brisbane, Gold Coast and surrounding South East Queensland service areas.
Unlike an all-in-one heat pump, the Emerald Split System uses a separate 300L storage tank and outdoor heat-pump unit. This provides considerably more flexibility when deciding where the cylinder and refrigeration unit can be positioned around the property.
The current HPRX300E-1 uses R290 refrigerant, DC inverter compressor and fan technology, a 3.6kW rated heat-pump heating capacity, Boost and Silent operating modes and a broad published ambient operating range from -15°C to 46°C.
Emerald 300L Split System at a glance: current model HPRX300E-1 combines a 300L tank with a separate outdoor heat-pump unit. Emerald specifies 3.6kW heating capacity from 1.8kW input under its stated test conditions, R290 refrigerant, 52–70°C leaving-water temperature range, 54dB(A) outdoor sound pressure, up to 20m refrigerant pipe length and up to 10m vertical separation. Emerald positions the system for both household and high-demand commercial applications.
PRODUCT AT A GLANCE
Emerald HPRX300E-1 Split Heat Pump
300L Storage
A large mains-pressure storage cylinder designed for applications needing a substantial reserve of hot water.
Split-System Design
The storage tank and heat-pump outdoor unit are separate, creating more installation flexibility than a one-piece heat pump.
3.6kW Heat Output
Emerald's current datasheet lists 3.6kW heat-pump heating capacity under its stated test conditions.
R290 Refrigerant
Uses R290 natural refrigerant with a published global warming potential of 3.
WHO IT SUITS
Where Does the Emerald 300L Split System Make Sense?
The 300L split system is particularly relevant where a property needs a larger stored-water volume but an all-in-one heat pump does not suit the available space, access or preferred equipment layout.
Higher-Demand Homes
The 300L tank provides a substantial stored hot-water reserve for homes where daily demand is too high for smaller heat-pump cylinders.
Properties With Difficult Layouts
Separating the cylinder from the outdoor unit can help where the best tank location and the best heat-pump airflow location are not the same place.
Commercial Applications
Emerald's current datasheet specifically identifies high-demand commercial settings such as gyms, salons and cafes as applications for the 300L split system.
Split does not mean installation anywhere. The tank, outdoor unit, refrigerant pipework, electrical supply, water services, drainage and servicing access still need to comply with the system's installation requirements.
WHY CHOOSE A SPLIT SYSTEM?
Split Heat Pump vs All-In-One Heat Pump
The main difference is where the refrigeration equipment sits. An all-in-one heat pump mounts the refrigeration system directly with the storage cylinder, while the Emerald split system places the fan and compressor in a separate outdoor unit.
Flexible Tank Location
Emerald states that the split-system tank can be positioned indoors or outdoors where the complete installation requirements can be met.
Outdoor Unit Outside
The heat-pump fan and compressor unit is installed outdoors where it can exchange heat with ambient air.
Separate Components
The two-piece design can suit narrow spaces and sites where an all-in-one heat pump would create clearance, access or positioning problems.
The split design is about placement flexibility, not fewer installation requirements. It introduces refrigerant pipework between the tank and outdoor unit, so the complete layout needs to be planned before installation.
FLEXIBLE PLACEMENT
How Far Apart Can the Tank and Outdoor Unit Be?
Emerald's current HPRX300E-1 technical data provides useful design limits for the refrigeration connection between the two components.
Up to 20m Pipe Length
Emerald lists a maximum refrigerant pipe length of 20 metres for the current system.
Up to 10m Height Difference
The current datasheet lists a maximum permitted height difference of 10 metres between the connected components.
Quick Connection
Emerald promotes a quick-connection design that does not require a conventional onsite vacuum process for the specified connection system.
These are manufacturer limits, not a recommendation to use the maximum distance on every job. The final equipment position and refrigerant route should be determined as part of the installation design.
HOW IT WORKS
How Does the Emerald Split Heat Pump Work?
The outdoor refrigeration unit collects heat from ambient air and transfers that heat through the refrigerant circuit to a heat exchanger associated with the storage tank.
Ambient Heat Is Collected
The outdoor fan moves air across the heat exchanger while the R290 refrigeration circuit captures available heat energy.
DC Inverter Compressor
The inverter rotary compressor drives the refrigeration cycle and can vary its operation rather than relying only on simple fixed-speed control.
Tank Water Is Heated
Heat is transferred into the stored water, which remains available in the 300L cylinder for normal hot water use.
OPERATING RANGE
Designed for a Wide Range of Ambient Conditions
Emerald publishes a broad operating-temperature range for the current split-system heat pump.
-15°C Minimum Ambient
Emerald lists heat-pump operation down to -15°C ambient under the product's stated operating range.
46°C Maximum Ambient
The upper published ambient operating limit is 46°C.
52–70°C Leaving Water
The current datasheet lists a leaving-water temperature range of 52°C to 70°C, with 70°C identified as the default in the specification table.
Maximum temperature is not the same as delivery temperature at every fixture. The completed plumbing installation still needs appropriate temperature control for personal-hygiene outlets where required.
BOOST & SILENT MODES
Control for Higher Demand or Quieter Operation
Boost Mode
Emerald provides a Boost mode intended to increase heating response when additional hot water is required more quickly.
Silent Mode
Silent mode reduces the sound output of the system when quieter operation is preferred.
Outdoor Sound Level
The current HPRX300E-1 datasheet lists an outdoor sound pressure level of 54dB(A) under its specified measurement conditions.
Location still matters for noise. Even with Silent mode available, the outdoor unit should be positioned with bedrooms, neighbouring properties and reflective walls considered where practical.
ENERGY SAVINGS
How Efficient Is the Emerald Split System?
Emerald currently promotes its split heat pump as its most efficient hot water system and advertises potential savings of up to 80% on hot-water costs under its stated comparison assumptions.
The current HPRX300E-1 technical datasheet separately lists a 3.6kW heating capacity and 1.8kW heating input under its stated test condition.
Heat Pump Technology
The system uses ambient heat as part of the water-heating process instead of relying solely on electric resistance heating.
DC Inverter Technology
Emerald states that its DC compressor and fan technology can adjust operation to match heating demand more accurately.
Actual Savings Vary
Household usage, electricity tariff, climate, target water temperature, installation conditions and use of auxiliary heating all affect real running costs.
“Up to 80%” is an Emerald manufacturer marketing claim, not a guaranteed bill reduction. Actual savings should be assessed against the system being replaced and the property's real electricity usage and tariff.
OPTIONAL ELECTRIC BOOST
Does the Emerald 300L Split Have an Electric Element?
Emerald's current datasheet states that an optional electric heater is available for the 300L split system to increase hot water supply when required.
4.2kW Capacity
The manufacturer lists the optional electric heater at 4.2kW.
Single Phase
Emerald lists a 220–240V single-phase supply for the optional heater.
Configuration Matters
The presence and electrical requirements of the auxiliary heater should be confirmed for the exact system being supplied rather than assumed from the heat-pump model name alone.

PHYSICAL SIZE
How Much Space Does the Emerald 300L Split Need?
Because the tank and outdoor unit are separate, the system does not need one tall all-in-one heat-pump footprint. It does, however, need suitable space for both components and the pipework joining them.
300L Tank
The current tank is approximately 580mm in diameter and 1735mm high, with an empty weight of about 106kg.
Outdoor Unit
The separate heat-pump unit measures approximately 804mm long, 327mm deep and 555mm high and weighs approximately 27kg.
Connected Layout
The final design also needs to account for refrigerant pipe routing, water pipework, drainage, electrical supply and service access.
The split arrangement can solve some space problems while creating different installation considerations. It is particularly useful when the best location for the storage tank does not provide suitable outdoor heat-pump airflow.
INSTALLATION REQUIREMENTS
What Is Required to Install an Emerald 300L Split Heat Pump?
Suitable tank location with adequate support for the 300L storage cylinder when full.
Outdoor heat-pump location with suitable airflow around the fan and heat exchanger.
Compliant refrigerant connection between the outdoor unit and tank within the manufacturer's permitted layout.
Suitable water services and pressure control for the mains-pressure storage cylinder.
PTR and storage-system drainage installed for the cylinder in accordance with the applicable installation requirements.
Suitable electrical supply for the exact system configuration being installed.
Service access to both the storage cylinder and outdoor refrigeration unit.
Licensed installation and commissioning covering the plumbing, electrical and refrigeration requirements of the split system.
A split heat pump is not simply a tank with a remote fan. Correct positioning and commissioning of the refrigerant circuit are fundamental parts of the installation.
REPLACEMENT OPTIONS
Can the Emerald 300L Split Replace My Existing Hot Water System?
Electric Storage Replacement
A suitable existing storage-system location can provide a starting point for the 300L tank while the separate heat-pump unit is positioned where outdoor airflow is available.
Existing Heat Pump
Replacing another split or all-in-one heat pump still requires the existing electrical, plumbing, drainage and equipment locations to be checked against the current Emerald requirements.
Relocation Opportunity
The split arrangement can create options where the current water heater position suits a tank but is unsuitable for the fan and compressor of an all-in-one system.
Do not assume an old storage position automatically makes the new installation simple. Split-system refrigerant routing and outdoor-unit placement need to be considered as part of the conversion.
RESIDENTIAL & COMMERCIAL
Can the Emerald 300L Split Be Used for Commercial Hot Water?
Yes. Emerald's current datasheet specifically describes the HPRX300E-1 as a high-capacity hot water system ideal for high-demand commercial settings, naming gyms, salons and cafes as examples.
Homes
Emerald's current split-system range is also promoted for household installations where large storage and flexible component placement are useful.
Gyms & Similar Sites
A 300L stored reserve can suit selected higher-demand applications where the actual daily draw and recovery requirements align with the system.
Cafes & Salons
Emerald includes these among its commercial examples, but individual commercial hot water demand should still be assessed before the system is selected.
Commercial suitability is application-specific. A 300L tank does not automatically make the unit suitable for every high-demand business. Peak draw, recovery requirements and operating hours should be considered.
GOVERNMENT INCENTIVES
Can the Emerald Split Heat Pump Qualify for Incentives?
Emerald promotes its heat-pump range as eligible for applicable energy-efficiency incentive programs where the approved product, installer, property and installation meet the current scheme requirements.
Eligibility, certificate quantities and rebate values can change, so a fixed rebate amount should not be embedded into long-form product content.
