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 |

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 absorb heat from the surrounding air and transfer it into swimming pool water. R290 is a natural hydrocarbon refrigerant with a Global Warming Potential (GWP) of approximately 3.
R290 is increasingly used in modern inverter pool heat pumps because it combines very low GWP with properties suited to high-efficiency heat pump systems.
Which Orilux pool heat pumps use R290?
Orilux OX16, OX20, OX26 and OX30 pool heat pumps use R290 refrigerant. These R290 inverter heat pump ranges are available in Australia through Avenza Pro and authorised Orilux dealers.
Is R290 better than R32 for pool heating?
R290 has a substantially lower Global Warming Potential than R32 — approximately 3 for R290 compared with approximately 675 for R32. This makes R290 attractive for newer heat pump designs where lower refrigerant environmental impact is a priority.
However, refrigerant alone does not determine which pool heat pump will perform best. Heating capacity, COP, inverter technology, compressor design, heat exchanger efficiency, correct sizing and operating conditions should all be considered.
Are R290 pool heat pumps more efficient?
R290 can support very high-efficiency pool heat pump designs, but refrigerant type alone does not determine efficiency. The overall system design — including the compressor, inverter, heat exchanger and control technology — has a major influence on performance.
Pool heat pump efficiency is commonly measured using COP. COP also changes with ambient air temperature, pool-water temperature and operating conditions.
How efficient are Orilux R290 pool heat pumps?
Orilux combines R290 refrigerant with inverter technology, Mitsubishi twin-rotary compressor technology, TurboSilence AI and titanium heat exchanger technology to provide high-efficiency pool heating.
Efficiency varies by model and operating conditions. Selected Orilux models achieve published COP figures of up to 30 under specified laboratory test conditions.
Does an R290 pool heat pump cost less to run?
Running cost depends on the efficiency of the complete heat pump rather than refrigerant type alone. Pool volume, climate, target water temperature, pool cover use, operating hours and electricity tariff all affect energy consumption.
Correct heat pump sizing and reducing heat loss with a pool cover can significantly reduce the energy required to maintain pool temperature.
Is R290 safe for swimming pool heat pumps?
R290 is an A3-classified flammable refrigerant, so R290 heat pumps must be designed, installed and serviced in accordance with the manufacturer's installation requirements and applicable regulations.
The refrigerant remains inside a sealed refrigeration circuit and does not mix with the swimming pool water. Correct equipment clearances, ventilation and qualified servicing are important when installing an R290 pool heat pump.
Can an R290 heat pump heat a pool in Melbourne or Victoria?
Yes. R290 pool heat pumps can be used for pool heating in Melbourne and across Victoria when the system is correctly sized for local climate conditions, pool size and the intended swimming season.
Cooler overnight temperatures, wind exposure and extended-season heating can increase heat demand, so Victorian pools may require greater heating capacity than similar pools in warmer Australian climates.
Is R290 suitable for saltwater swimming pools?
Yes, an R290 heat pump can be used with a saltwater swimming pool when the heat pump's water-side components are designed for pool applications. R290 is contained inside the refrigeration circuit and does not come into direct contact with the pool water.
Saltwater compatibility primarily depends on the heat exchanger and correct pool-water chemistry. Orilux pool heat pumps use titanium heat exchanger technology designed for swimming pool heating applications.
What size R290 pool heat pump do I need?
The correct R290 pool heat pump size depends on pool volume, location, ambient temperature, desired water temperature, swimming season, wind exposure and pool cover use.
Larger heat pumps generally provide faster initial heat-up and greater heating capacity during cooler weather, while inverter technology allows output to reduce once the target pool temperature is reached.
Which Orilux R290 pool heat pump should I choose?
The right Orilux R290 pool heat pump depends on the heating demand of the pool rather than pool volume alone.
OX16 — residential and mainstream family pool applications.
OX20 — larger pools or higher heating-demand applications.
OX26 — premium performance, broader capacity selection and extended swimming seasons.
OX30 — flagship Orilux R290 platform for efficiency-focused applications.

What should I look for when choosing an R290 pool heat pump?
When comparing R290 pool heat pumps, consider heating capacity, COP, inverter performance, compressor technology, heat exchanger design, operating temperature range, noise level, warranty, technical support and correct sizing.
Refrigerant choice is important, but the performance of the complete heat pump system determines how effectively and efficiently it will heat your pool.
