🙋 Frequently Asked Questions
1. What size pool is the X20-16 suitable for?
The X20-16 is designed for medium to large residential pools with volumes between 35–60 m³ (35,000–60,000 litres). This typically corresponds to pools measuring 8–12 meters in length with standard depths of 1.2–1.5 meters. For larger pools, consider the 18kW or 20kW models for faster heating times.
2. How much does it cost to run the X20-16?
Running costs depend on your pool size, desired temperature, climate, and usage pattern. For a typical 45 m³ pool heated to 28°C over a 6-month UK swimming season, expect annual electricity costs of approximately £250–£400 (based on £0.30/kWh). This is 70–85% cheaper than electric or gas heaters. Using Smart or Silence mode and a pool cover can reduce costs further.
3. How long does it take to heat my pool?
Heat-up time depends on pool volume, temperature increase needed, and ambient conditions. As a general guide for a 45 m³ pool with a good cover:
- 5°C rise: 18–22 hours (Turbo Mode)
- 10°C rise: 35–42 hours (Turbo Mode)
Uncovered pools take 40–60% longer. Using the heat pump consistently to maintain temperature is much more efficient than heating from cold repeatedly.
4. Can it work in winter or cold weather?
Yes! Unlike many heat pumps, the X20-16 operates reliably down to -20°C ambient temperature. While heating output reduces in very cold conditions (this is normal for all heat pumps), the advanced defrost system and low-temperature optimized compressor ensure continuous operation. At 7°C ambient, it still delivers 9.2 kW in Turbo Mode with a COP of 4.6–7.2.
5. How loud is the X20-16?
The X20-16 is one of the quietest pool heat pumps available:
- 41–47 dB(A) at 1 meter: Similar to a quiet conversation or library

Silence Mode reduces noise even further (down to 41 dB(A) at 1m), making it ideal for evening use or noise-sensitive neighborhoods.
6. What is COP and why does it matter?
COP (Coefficient of Performance) measures efficiency – how much heating you get per unit of electricity consumed. The X20-16 achieves COP values of 7.4–20.5 depending on conditions, with an average exceeding 15.
Example: At COP 15, for every 1 kW of electricity consumed (costing £0.30), you receive 15 kW of heating output. To get the same heat from an electric heater would cost £4.50 – saving you £4.20 per hour of operation.
7. What’s the difference between Turbo, Smart, and Silence modes?
- Turbo Mode (100–120%): Maximum heating power for rapid temperature increases or very cold weather. Uses 16.5 kW output. Best for initial heat-up or recovering from extended pool closure.
- Smart Mode (20–100%): Automatically adjusts output based on temperature difference and conditions. Uses 14.0 kW output typically. Best for day-to-day temperature maintenance with balanced efficiency.
- Silence Mode (20–60%): Reduced output for ultra-quiet operation, perfect for evening use or noise-sensitive areas. Still provides sufficient heating for maintaining temperature in mild conditions.
8. Do I need a pool cover?
While not mandatory, a pool cover is highly recommended and will:
- Reduce heat loss by 60–80% overnight and during non-use periods
- Cut running costs by 40–60% by retaining heat
- Speed up heat-up times dramatically
- Reduce water evaporation and chemical usage
- Keep debris out of the pool
A good cover can pay for itself within one season through energy savings alone.
