📋 Frequently Asked Questions

Q1: What size pool is the X20-32T suitable for?

A: The X20-32T is designed for pools between 65m³ and 105m³ (14,300 – 23,100 UK gallons / 17,175 – 27,735 US gallons). This makes it ideal for large residential pools, hotel pools, leisure center pools, and commercial aquatic facilities. For optimal performance, we recommend using it within this range—undersizing will result in long heat-up times while oversizing may reduce efficiency.

Q2: Can this heat pump work in winter temperatures?

A: Absolutely! The X20-32T operates in ambient temperatures as low as -20°C and as high as +43°C. It features an automatic defrost system that prevents ice buildup on the evaporator coil during cold weather operation. However, heating efficiency (COP) decreases as ambient temperature drops. At 7°C ambient, the unit still delivers 17.8kW with COP around 4.5-7.0.

Q3: How much does it cost to run compared to gas heating?

A: The X20-32T typically costs 60-70% less to operate than a gas boiler for the same heating output. For an 85m³ pool over a 6-month season, expect running costs of £800-£1,200 with a heat pump versus £2,500-£3,500 for gas heating (based on current UK energy prices). The high COP means you generate significantly more heat energy than the electrical energy consumed.

Q4: Do I need three-phase power for this model?

A: Yes, the X20-32T requires a 400V three-phase power supply. This is standard in commercial installations and many larger residential properties, but not in typical UK homes which have single-phase supply. If you have a smaller pool or only single-phase power, consider the X20-32 model (single-phase, 32kW output) or other models in the InverX20 range.

Q5: How quiet is the heat pump in Silence Mode?

A: In Silence Mode, the X20-32T operates at just 42-45 dB(A) at 1 meter and 22-25 dB(A) at 10 meters. This is quieter than a typical refrigerator and similar to a quiet library. At 10 meters (typical installation distance from living areas), it’s comparable to rustling leaves. This makes it suitable for nighttime operation even in residential neighborhoods.

Q6: What warranty comes with this heat pump?

A: The X20-32T includes an industry-leading warranty package:

• 15 years on the Mitsubishi compressor
• 15 years on the titanium heat exchanger
• 7 years on all other parts

This comprehensive coverage reflects Fairland’s confidence in the quality and durability of their components.

Q7: Can I control the heat pump from my smartphone?

A: Yes! The X20-32T features built-in Wi-Fi and works with the Fairland smartphone app (iOS and Android). You can remotely monitor water temperature, adjust settings, change operating modes, view power consumption, schedule operation times, and receive alerts. The app also allows you to share control with family members or facility staff.

Q8: What’s the difference between Turbo, Smart, and Silence modes?

A:

• Turbo Mode (100-120%): Maximum power output (32kW+) for rapid heating. Use for initial heat-up or recovering from cold weather. Slightly louder operation.
• Smart Mode (20-100%): Intelligent automatic adjustment based on ambient and water temperatures. Balances efficiency and speed. Recommended for everyday use.
• Silence Mode (20-60%): Reduced output for ultra-quiet operation. Perfect for nighttime heating or noise-sensitive environments. Maintains temperature rather than rapid heating.

Q9: How long does it take to heat my pool initially?

A: Heat-up time depends on pool volume and desired temperature rise. For an 85m³ pool:

• 5°C temperature rise: ~15 hours (Turbo), ~18 hours (Smart)
• 10°C temperature rise: ~30 hours (Turbo), ~36 hours (Smart)
• 15°C temperature rise: ~46 hours (Turbo), ~55 hours (Smart)

These are estimates for ideal conditions (covered pool, no wind, consistent ambient temperature). Always use a pool cover during heat-up to minimize heat loss.

Q10: Does the heat pump need regular maintenance?

A: Annual professional maintenance is recommended. This includes:

• Cleaning the evaporator coil (outdoor coil)
• Checking refrigerant pressure
• Inspecting electrical connections
• Testing safety controls
• Checking water flow and connections
• Verifying correct operation of all modes

Additionally, you should regularly:

• Keep the area around the unit clear
• Ensure good airflow (remove leaves/debris)
• Check for water leaks
• Maintain proper pool water chemistry

Q11: Can I use this with saltwater pools?

A: Yes! The titanium heat exchanger is specifically designed to resist corrosion from all water types including saltwater, chlorinated water, and treated pool water. Titanium offers superior corrosion resistance compared to cupronickel or stainless steel exchangers used in cheaper heat pumps.

Q12: What happens if there’s a power cut?

A: The X20-32T features auto-restart after power loss. When power is restored, the unit will automatically resume operation at the previous settings. No manual intervention required. This is particularly useful for commercial installations or areas with occasional power interruptions.
