❓ Frequently Asked Questions

Q: How long does it take to heat my pool initially?

A: This depends on your pool volume and desired temperature rise. For a 40m³ pool raising temperature by 5°C, expect approximately 40-48 hours of operation. Using Turbo mode can reduce this by up to 20%. Always use a pool cover to minimize heat loss during initial warm-up.

Q: How quiet is the InverX really?

A: At 38.6-46.9 dB(A) at 1 meter, it’s comparable to a quiet conversation or a modern refrigerator. At 50% capacity (normal maintenance mode), it drops to just 41.3 dB(A). At 10 meters distance, noise is barely perceptible at 18.6-26.9 dB(A). This is genuinely 10x quieter than standard inverter heat pumps.

Q: Can it really work in winter at -15°C?

A: Yes! The IXR36 operates down to -15°C ambient temperature, though output will be reduced at these extremes. It’s ideal for shoulder seasons (spring/autumn) and can even be used for winter swimming if you’re dedicated. However, expect lower COPs and higher running costs below 10°C.

Q: What’s the difference between Smart, Turbo, and Silence modes?

A: Turbo mode runs at 120% capacity (13kW) for rapid heating – use this when starting the season or after cold periods. Smart mode intelligently varies between 20-100% capacity (averaging 50%) to maintain temperature efficiently – this is your everyday mode offering the best balance of performance and economy. Silence mode limits operation to 20-80% capacity for ultra-quiet running – perfect for evening swimming or noise-sensitive areas.

Q: Do I need WiFi for the heat pump to work?

A: No, the heat pump functions perfectly without WiFi using the built-in touchscreen controls. WiFi connectivity is an optional convenience feature that allows remote monitoring and control via the smartphone app. Many users find the app invaluable for scheduling and monitoring, but it’s not required for operation.

Q: How much does it cost to run compared to gas heating?

A: The IXR36 typically costs 50-70% less to run than gas heating, thanks to its exceptional COP (up to 16:1 in ideal conditions vs. gas heaters at roughly 0.8-0.9:1). For every 1kW of electricity consumed, you receive up to 16kW of heat output. A gas heater provides less than 1kW of heat per 1kW of gas consumed.

Q: What maintenance does it require?

A: Very minimal! Monthly: Check water flow and clean pool filter. Seasonally: Clean the heat exchanger fins with gentle water spray (from inside out), check electrical connections, ensure condensate drains freely. Annually: Professional inspection recommended. The sophisticated control system provides maintenance alerts when service is needed.

Q: Is the heat exchanger really warranted for 12 years?

A: Yes! The premium titanium heat exchanger carries an industry-leading 12-year warranty, with the compressor covered for 10 years and all other components for 3 years. This demonstrates the manufacturer’s confidence in long-term durability.

A: Yes! The InverX IXR36 features intelligent pool pump control. It can automatically turn your filtration pump on/off based on heating requirements, optimizing both heating efficiency and reducing pump running costs. This feature requires compatible equipment and proper installation.

Q: What size pool is this heat pump suitable for?

A: The IXR36 is optimally sized for pools between 25-50m³. For pools at the lower end (25-35m³), you’ll enjoy faster heating and maximum efficiency. For pools at the upper end (45-50m³), heating will take longer but the system will still maintain temperature effectively. Always size up if your pool is borderline or you want faster heat-up times.

Q: Do I need a bypass valve?

A: While not absolutely mandatory, a bypass valve is strongly recommended. It allows you to adjust water flow to the optimal 3-4 m³/h rate, which maximizes efficiency and prevents error codes. The IXR36’s built-in flow indicator makes adjustment easy. Most professional installers include a bypass as standard.

Q: How does the COP vary with temperature?

A: COP decreases as ambient temperature drops – this is normal for all heat pumps. At 26°C ambient, the IXR36 achieves COPs of 15.5-7.5. At 15°C ambient, COP ranges from 7.0-5.0. Even at lower temperatures, the IXR36 remains far more efficient than gas or electric resistance heating.

Q: What happens if there’s a power cut?

A: The heat pump will automatically restart when power is restored, returning to the previous settings. Your pool will cool naturally during the outage. If you have a pool cover, heat loss will be minimal during typical short power interruptions.
