Aquatech & Hydrotherm Heat Pump Hot Water Systems
Aquatech and Hydrotherm heat pump hot water systems provide all-in-one electric hot-water options for homes replacing conventional electric storage or upgrading to heat-pump technology.
The current Installed Today range combines the Aquatech RAPID/X6 210L and Hydrotherm DYNAMIC/X8 260L, providing two clear capacity choices from the Aquatech Solar Technologies product family.
Installed Today supplies Aquatech and Hydrotherm heat pumps across supported mainland Australian markets, with supplied and installed options available in eligible Brisbane and Gold Coast service areas.
Aquatech RAPID/X6 & Hydrotherm DYNAMIC/X8
Aquatech X6 vs Hydrotherm X8
| Model | Capacity | Approx. Size | Heat Pump Output | Best Starting Point |
|---|---|---|---|---|
| Aquatech RAPID/X6 | 210L | 1582 × 620mm | Approx. 2.65kW under stated conditions | Moderate family demand / around 4 people |
| Hydrotherm DYNAMIC/X8 | 260L | 1800 × 620mm | Approx. 3.6kW rated heating capacity | Larger family and higher-use households |
Household sizing is a starting point only. Shower length, bathrooms, baths, peak use, recovery, climate and operating schedule can all change the correct capacity.
Why Aquatech and Hydrotherm Are Together
Hydrotherm operates under Aquatech Solar Technologies Pty Ltd, making the two names closely related rather than completely separate manufacturers.
Keeping Aquatech and Hydrotherm together makes it easier to compare the RAPID/X6 and DYNAMIC/X8 as two steps within the same broader heat-pump product family.
This also creates a clearer brand page than maintaining two separate collections with only one current model each.
Aquatech RAPID/X6 210L Heat Pump
The Aquatech RAPID/X6 is the smaller current model in this collection.
It combines a 210L vitreous-enamel tank with R290 heat-pump technology in a unit approximately 1582mm high × 620mm diameter.
Its compact footprint makes it particularly relevant when replacing a conventional electric-storage system where available space is limited.
Who Should Consider the RAPID/X6 210L?
Installed Today currently positions the Aquatech X6 around four occupants as a practical starting point.
It can suit smaller family homes, townhouses, secondary dwellings, lower-occupancy rentals and households replacing common electric storage systems.
Homes with heavier back-to-back shower demand should compare the larger DYNAMIC/X8 before choosing the X6 simply because it is more compact.
Eco, Standard, Hybrid & Hybrid+ Modes
The RAPID/X6 provides four operating modes: Eco, Standard, Hybrid and Hybrid+.
These modes allow the system to vary how heat-pump and electric-element heating are used depending on household demand and recovery priorities.
Faster or element-assisted modes can increase electricity consumption, so the highest-recovery setting is not automatically the best everyday operating mode.
Aquatech RAPID/X6 Recovery
Published RAPID/X6 specifications list heat-pump heating capacity around 2.65kW and approximately 225 minutes for the stated recovery test.
Recovery varies with ambient temperature, incoming water temperature, operating mode and actual household use.
The X6 also incorporates a 1.8kW electric element for additional heating support.
Hydrotherm DYNAMIC/X8 260L Heat Pump
The Hydrotherm DYNAMIC/X8 provides the larger capacity option in the current combined range.
It uses a 260L vitreous-enamel tank and measures approximately 1800mm high × 620mm diameter.
Its additional storage makes it more relevant to family homes and higher-use households needing more reserve than the 210L X6.
Hydrotherm X8 for Higher Hot-Water Demand
Hydrotherm positions the DYNAMIC/X8 toward family households and higher hot-water use.
Current manufacturer material places the 260L model broadly within a 3–6 person range, depending on operating schedule and household usage.
The additional 50L of nominal storage can be particularly useful where the system is scheduled to heat during limited daytime or solar periods.
Hydrotherm DYNAMIC/X8 Heating Performance
Current manufacturer specifications list rated heating capacity around 3.6kW and rated electrical input around 0.88kW.
The system uses R290 refrigerant and a rotary compressor with a micro-channel condenser.
Tank recovery is listed at around four hours under stated conditions.
When Should You Choose the X8 Instead of the X6?
Choose X6 When
Household demand is moderate, installation space is tighter and a 210L tank provides enough stored hot water.
Choose X8 When
The household needs greater stored capacity, has stronger peak demand or wants more reserve between heating periods.
Do Not Size by Litres Alone
Recovery rate, heating schedule, showers, bathrooms and operating modes can matter as much as the nominal tank volume.
Aquatech & Hydrotherm Use R290 Refrigerant
Both current models use R290 refrigerant within their sealed refrigeration circuits.
R290 is commonly used in newer heat-pump hot-water systems due to its favourable thermodynamic properties and comparatively low global warming potential.
Refrigerant type should still be considered alongside capacity, recovery, controls, noise, installation requirements and warranty.
1.8kW Electric Element Support
Both the RAPID/X6 and DYNAMIC/X8 use an 1.8kW electric heating element as part of their hybrid heating strategy.
The element can support higher water temperatures or faster recovery when required by the selected operating mode.
Heat-pump efficiency comparisons should focus primarily on normal heat-pump operation rather than assuming the element operates continuously.
Heat Pump and Element Water Temperatures
Current product specifications allow heat-pump heating to approximately 60°C.
Electric-element support can allow tank temperatures up to approximately 70°C, depending on the model and operating mode.
Delivered hot-water temperature at fixtures remains subject to tempering and plumbing requirements.
Aquatech & Hydrotherm Use a 10A Single-Phase Circuit
Current RAPID/X6 and DYNAMIC/X8 specifications use a 220–240V, 10A single-phase circuit.
Their current documentation specifies a hardwired and isolated electrical connection.
That means 10A-compatible should not be confused with a standard plug-and-lead appliance.
The electrical installation still needs suitable isolation, circuit protection and compliance for the selected system.
Aquatech & Hydrotherm with Rooftop Solar
Both product families support timer-based operating strategies that can help move hot-water heating toward daytime solar-generation periods.
Because heat pumps store heated water for later use, the heating cycle can occur during the day even where most showers happen in the morning or evening.
Solar-friendly scheduling does not guarantee that every heating cycle will operate entirely from surplus rooftop solar.
Replacing Electric Storage with Aquatech or Hydrotherm
Both models are particularly relevant to customers replacing conventional electric-storage hot water.
The X6's compact footprint makes it a practical comparison for many standard residential electric-storage replacements.
The X8 provides a larger-capacity pathway for homes currently using bigger electric tanks or households with stronger demand.
Do not automatically match the old electric-storage litres to the new heat-pump litres. Recovery and operating schedule also affect sizing.
Replacing 315L or 400L Electric Storage with Hydrotherm X8
Hydrotherm specifically positions the 260L DYNAMIC/X8 as a potential replacement for selected 315L to 400L conventional electric-storage systems.
That does not mean every 315L or 400L household should automatically move to a 260L heat pump.
Household demand, recovery, tariff, shower habits and available heating time need to confirm that the smaller nominal tank can keep up.
Vitreous-Enamel Hot Water Storage
Both current models use vitreous-enamel-lined storage cylinders.
Tank protection and servicing should be considered alongside water quality, anode configuration and the applicable manufacturer warranty.
Tank material alone should not be used as a complete measure of heat pump quality or expected service life.
Aquatech X6 Is More Compact Than Hydrotherm X8
| Model | Height | Diameter | Empty Weight | Minimum Base |
|---|---|---|---|---|
| RAPID/X6 | Approx. 1582mm | 620mm | Approx. 108kg | 600 × 600mm |
| DYNAMIC/X8 | Approx. 1800mm | 620mm | Approx. 118kg | 600 × 600mm |
Heat Pump Airflow Needs to Be Considered
Aquatech and Hydrotherm systems extract energy from surrounding air.
The installation position therefore needs sufficient airflow around the heat-pump section and appropriate manufacturer clearances.
Installing a heat pump in a cramped or poorly ventilated position can affect performance and make the location unsuitable.
Heat Pumps Need Condensate Drainage
Heat-pump operation can produce condensate as moisture in the surrounding air is cooled.
Both the X6 and X8 need suitable condensate drainage as part of the installation.
Normal hot-water valve discharge and drainage requirements also need to be considered separately.
Consider Bedrooms, Neighbours & Outdoor Living Areas
Heat pumps use a compressor and fan, so the installation position matters even where the product is considered relatively quiet.
Avoid choosing a position based purely on plumbing convenience if it places the heat pump beside bedroom windows, a neighbour's sleeping area or a frequently used outdoor living space.
When comparing published noise figures between heat pumps, check the measurement distance and test conditions before deciding one model is quieter than another.
Aquatech & Hydrotherm Warranty
Current Installed Today product data lists a maximum 6-year warranty for the Aquatech RAPID/X6.
Current Hydrotherm documentation lists the DYNAMIC/X8 with a 6-year full warranty, subject to Hydrotherm warranty conditions.
Always check the current model-specific warranty document at purchase because warranty structure and eligibility conditions can change.
Aquatech & Hydrotherm Heat Pump STCs
Eligible Aquatech and Hydrotherm heat-pump installations can qualify for Small-scale Technology Certificates and may also qualify for other available incentives.
Certificate quantities and rebate values depend on the exact model, climate zone, installation date and current scheme rules.
Always confirm current eligibility when ordering rather than relying on an old published rebate amount.

What are the most popular Aquatech and Hydrotherm heat pump hot water systems?
The two main options currently available from Installed Today are the Aquatech X6 Rapid 210L and the Hydrotherm X8 Dynamic 260L . The X6 is the smaller option and is a popular choice for households of around 4 people, while the larger X8 is commonly compared by families of around 5 people or homes wanting additional stored hot water capacity.
What is the difference between the Aquatech X6 Rapid 210L and Hydrotherm X8 Dynamic 260L?
The main difference is storage capacity and household suitability. The Aquatech X6 Rapid has a 210L tank and is commonly suited to households of around 4 people. The Hydrotherm X8 Dynamic has a larger 260L tank and is commonly suited to around 5 people or households with higher daily hot water demand. The larger X8 can provide more stored hot water, while the X6 offers a more compact option where 210L is sufficient.
Is the Aquatech X6 Rapid 210L suitable for a family of 4?
Yes. The Aquatech X6 Rapid 210L is currently recommended by Installed Today for around 4 occupants. Its 210L tank can suit smaller family homes with normal daily hot water demand. Actual suitability still depends on shower length, shower flow rate, bath use, climate, operating mode and how closely together household members use hot water.
Is the Hydrotherm X8 Dynamic 260L suitable for a family of 5?
The Hydrotherm X8 Dynamic 260L is commonly considered for family households of around 5 people. Its larger 260L storage capacity gives it more stored hot water than the 210L X6, making it the better comparison where household demand is higher, showers are longer or several people regularly use hot water within a short period.
How big is the Aquatech X6 Rapid 210L heat pump?
The Aquatech X6 Rapid 210L is approximately 1582mm high and 620mm wide. It has a 210L vitreous-enamel steel cylinder and is designed as an integrated heat pump hot water system. Before ordering, check the available installation area as well as the required airflow, drainage, pipework, electrical supply and future service access around the system.
Is the Aquatech X6 Rapid heat pump noisy?
The current Aquatech X6 Rapid 210L specification lists an operating noise level of approximately 49dB. Like all heat pumps, it uses a compressor and fan while operating, so installation position matters. Avoid placing a heat pump immediately beside bedroom windows or other noise-sensitive areas where possible, and maintain the manufacturer's required airflow and service clearances.
Can I replace an electric hot water system with an Aquatech or Hydrotherm heat pump?
In many homes, yes. An Aquatech or Hydrotherm heat pump can be used as an energy-efficient alternative when replacing a traditional electric storage hot water system. It is not always a simple like-for-like tank replacement because the heat pump needs suitable outdoor airflow, condensate drainage, electrical supply, a compliant base, plumbing connections and adequate service access. Additional work may be required if the existing installation does not suit the new system.
Does the Aquatech X6 Rapid use R290 refrigerant?
Yes. The current Aquatech X6 Rapid 210L uses R290 refrigerant as part of its heat pump refrigeration system. The unit draws heat from the surrounding air and transfers that energy into the stored water, reducing its reliance on direct electric resistance heating compared with a conventional electric storage tank.
Can I buy an Aquatech or Hydrotherm heat pump supply only?
Yes. Supply only means you are purchasing the heat pump hot water system without an Installed Today installation package. This option is suited to customers who already have the appropriate licensed installer arranged. Installation labour, valves, disposal, additional pipework, electrical alterations, drainage changes, base work and other site-specific upgrades are not included unless purchased separately.
Can I buy an Aquatech or Hydrotherm heat pump supplied and installed?
Yes. Supplied and installed options are available on selected systems in eligible installation areas. The Basic Install is intended for an eligible external, ground-level heat pump replacement in the existing location.
