What is an R290 pool heat pump?
An R290 pool heat pump uses refrigerant-grade propane to transfer heat from the surrounding air into swimming pool water.
R290 is a natural hydrocarbon refrigerant with a Global Warming Potential of approximately 3. By comparison, R32 is a synthetic HFC refrigerant with a GWP of approximately 675.
The refrigerant operates inside a sealed circuit. The heat pump draws heat energy from ambient air, raises its temperature through the refrigeration cycle and transfers that heat to the pool through a titanium heat exchanger.
Important: R290 alone does not determine how efficient a pool heater will be. Compressor technology, inverter control, heat exchanger design, ambient temperature, water temperature, installation and correct sizing all affect real-world performance.
Why are pool heat pump manufacturers moving to R290?
R290 provides manufacturers with a very low-GWP refrigerant platform for modern inverter heat pump design. Its value comes from how it is engineered into the complete system.
Very low GWP
R290 has a Global Warming Potential of approximately 3, substantially lower than common HFC refrigerants.
Natural refrigerant
R290 is refrigerant-grade propane: a natural hydrocarbon rather than a synthetic HFC refrigerant.
Inverter compatible
In a well-designed system, R290 can be paired with intelligent variable-speed control and efficient heat transfer.
Lower-GWP direction
Australia is reducing bulk HFC imports, while government guidance identifies hydrocarbons among the available alternatives.
R290 vs R32 pool heat pumps
R290 has a much lower GWP than R32, but refrigerant type is only one part of choosing a pool heat pump. Compare the complete product, its performance data, sizing, installation requirements, warranty and support.
| Comparison | R290 | R32 |
|---|---|---|
| Refrigerant family | Natural hydrocarbon | Synthetic HFC |
| Common name | Refrigerant-grade propane | Difluoromethane |
| Approximate GWP | 3 | 675 |
| Safety classification | A3 — higher flammability | A2L — lower flammability |
| Australian HFC phase-down | R290 is a hydrocarbon, not an HFC | R32 is an HFC; the phase-down applies to bulk HFC imports |
| Efficiency | Depends on the complete heat pump design and operating conditions | Depends on the complete heat pump design and operating conditions |

Which Orilux R290 heat pump should I choose?
Choose the range first by heating demand and desired performance, then select the exact capacity using pool volume, postcode, ambient temperature, target temperature, swim season, exposure and pool cover use.
Choose OX16
For efficient residential pool heating and mainstream family-pool applications.
Choose OX20
For larger pools or higher heating demand with 120% TurboSilence output.
Choose OX26
For premium performance, broad capacity choice and extended-season swimming.
Choose OX30
For the flagship Orilux platform and premium efficiency-focused applications.
Is R290 safe in a pool heat pump?
R290 is classified A3 because it has higher flammability. This makes product engineering, installation location, clearances, ventilation, servicing procedures and compliance with the manufacturer's instructions important.
In an Orilux pool heat pump, the refrigerant is contained within a purpose-designed sealed circuit. Owners should never modify the refrigerant system and should use appropriately qualified technicians where installation or refrigerant work requires them.
- Follow the model-specific installation manual and clearances.
- Keep required ventilation areas free from obstruction.
- Do not place ignition sources within prohibited clearances.
- Use authorised support for service and warranty assistance.

Common questions about R290 pool heat pumps
What is an R290 pool heat pump?
An R290 pool heat pump uses refrigerant-grade propane in a sealed refrigeration circuit to collect heat from ambient air and transfer it into pool water. R290 is a natural hydrocarbon refrigerant with a Global Warming Potential of approximately 3.
Which pool heat pumps use R290 in Australia?
The Orilux OX16, OX20, OX26 and OX30 are R290 inverter pool heat pump ranges available in Australia through Avenza Pro and authorised Orilux dealers.
Does Orilux use R290 refrigerant?
Yes. The Orilux OX16, OX20, OX26 and OX30 pool heat pump ranges use R290. They also include TurboSilence AI, smart Wi-Fi, IOTA updates, aluminium-alloy casing and heating and cooling capability.
Is R290 better than R32 for pool heating?
R290 has a substantially lower GWP than R32: approximately 3 compared with approximately 675. However, the best pool heat pump should be judged as a complete system. Correct sizing, inverter control, heat exchanger design, climate performance, warranty and support also matter.
Is an R290 pool heat pump more efficient?
R290 can support highly efficient heat pump designs, but the refrigerant alone does not establish efficiency. Published performance depends on the compressor, inverter, heat exchanger, control system and test conditions. Real-world efficiency also changes with air and pool-water temperature.
Does R290 reduce pool heating running costs?
Running costs depend on the efficiency and design of the complete heat pump, not just its refrigerant. Pool size, weather, target temperature, cover use, runtime and electricity tariff can have a major effect. Correct sizing and using a pool cover are especially important.
Can an R290 heat pump heat a pool in Melbourne or Victoria?
Yes, when the heat pump is correctly sized for cooler conditions and the intended swimming season. Victorian pools often require more capacity than comparable pools in warmer regions. Pool covers, wind exposure, target temperature and overnight heat loss must be included in sizing.
Is R290 suitable for saltwater pools?
R290 is the refrigerant inside the sealed system and does not contact the pool water. Saltwater compatibility depends primarily on the water-side heat exchanger and correct water chemistry. Orilux uses titanium heat exchanger technology for swimming pool applications.
What size R290 pool heat pump do I need?
The right size depends on pool volume, postcode, ambient temperature, desired water temperature, swimming season, exposure and pool cover use. Use the Avenza Pro pool heat pump calculator for an initial Orilux recommendation, then confirm selection with a dealer or installer.
