Heat-Up Time Calculator ⏱
How long will it take to heat my pool?
Below are estimated heat-up times based on the Silent-Pro 10’s performance at different ambient temperatures. Actual times will vary based on pool insulation, cover usage, wind exposure, and starting water temperature.
Heat-Up Time Estimates (Initial Heating)
Pool Volume: 35m³ (example: 7m × 5m × 1m)
| Ambient Temp | Temperature Rise | Estimated Time* |
|---|---|---|
| 27°C | 20°C → 28°C (8°C rise) | 12-14 hours |
| 15°C | 20°C → 28°C (8°C rise) | 18-22 hours |
| 10°C | 18°C → 26°C (8°C rise) | 24-28 hours |
Pool Volume: 45m³ (example: 9m × 5m × 1m)
| Ambient Temp | Temperature Rise | Estimated Time* |
|---|---|---|
| 27°C | 20°C → 28°C (8°C rise) | 15-18 hours |
| 15°C | 20°C → 28°C (8°C rise) | 23-27 hours |
| 10°C | 18°C → 26°C (8°C rise) | 30-36 hours |
Pool Volume: 55m³ (example: 11m × 5m × 1m)
| Ambient Temp | Temperature Rise | Estimated Time* |
|---|---|---|
| 27°C | 20°C → 28°C (8°C rise) | 19-22 hours |
| 15°C | 20°C → 28°C (8°C rise) | 28-34 hours |
| 10°C | 18°C → 26°C (8°C rise) | 38-45 hours |
Formula Used: Time (hours) = (Pool Volume m³ × Temperature Rise °C × 1.16) ÷ Average Heat Pump kW
⚠️ Important Disclaimers:
- Estimates assume properly insulated pools with covers
- Actual performance varies with humidity, wind, and pool heat loss
- Using a pool cover can reduce heat-up time by 30-50%
- Heat pumps maintain temperature more efficiently than initial heating
- For fastest heat-up, run heat pump continuously (24/7) until target reached
Maintenance Heat-Up (Daily Temperature Recovery)
Once your pool is at temperature, the Silent-Pro 10 efficiently maintains it:
| Daily Heat Loss* | Recovery Time (27°C ambient) | Recovery Time (15°C ambient) |
|---|---|---|
| 1°C drop | 1.5 – 2 hours | 2 – 3 hours |
| 2°C drop | 3 – 4 hours | 4 – 6 hours |
| 3°C drop | 4.5 – 6 hours | 6 – 9 hours |

💰 Annual Savings with Silent-Pro 10:
- vs. Electric Heater: £3,500 – £5,000 saved
- vs. Gas Boiler: £1,000 – £1,400 saved
Payback Period: Typically 2-4 years depending on usage and electricity rates
***Based on UK average electricity rate of £0.30-£0.40/kWh (2024-2025). Actual costs vary by tariff, usage, and local climate.
Cost Per Swim Session 🏊
| Session Type | Energy Used | Cost Per Session |
|---|---|---|
| Maintain temp (pre-heated pool) | 3-5 kWh | £0.90 – £2.00 |
| Heat 2°C (morning warm-up) | 8-10 kWh | £2.40 – £4.00 |
| Full day heating (10 hours) | 15-20 kWh | £4.50 – £8.00 |
💡 Money-Saving Tips:
- Always use a pool cover – reduces heat loss by up to 70%
- Heat during off-peak hours – if on time-of-use tariff
- Set temperature 1-2°C lower – reduces running time significantly
- Use Solar Cover – free passive heating during the day
- Maintain water chemistry – dirty water is harder to heat

Frequently Asked Questions ❓
1. How efficient is the Silent-Pro 10 compared to traditional heaters?
The Silent-Pro 10 achieves a COP (Coefficient of Performance) of up to 16.1, meaning it produces 16 kW of heat for every 1 kW of electricity consumed. This makes it approximately 5-6 times more efficient than electric resistance heaters and 3-4 times more efficient than gas boilers. Real-world savings typically amount to £3,000-£5,000 annually compared to electric heaters.
2. Will it work during cold UK winters?
Absolutely! The Silent-Pro 10 operates down to -15°C ambient temperature. While heating capacity reduces in colder temperatures (this is normal for all heat pumps), it continues to work effectively. For example, at 10°C ambient, it still delivers 5.53 kW of heating. The automatic defrost function prevents ice build-up on the coils, ensuring reliable year-round operation.
3. How quiet is it really? Will it annoy my neighbours?
The Silent-Pro 10 is one of the quietest heat pumps available. At 10 metres distance (typical fence line), it operates at just 16.5-27 dB(A) – quieter than rustling leaves or a whisper. Even at 1 metre, it’s only 36-46 dB(A) (similar to a quiet library). The horizontal double-side airflow and low-speed fan ensure minimal noise pollution, making it ideal for residential areas with noise-sensitive neighbours.
4. Can I control it from my smartphone?
Yes! The Silent-Pro 10 comes with an integrated WiFi module and works with the free NorsupOne app (iOS & Android). You can remotely adjust temperature, switch operating modes, set schedules, monitor energy usage, and receive maintenance alerts – all from your smartphone. The unit also has a full-colour touchscreen for manual control.
5. What size pool is it suitable for?
The Silent-Pro 10 is designed for pools between 30-55 m³ (when properly insulated with a cover). For reference:
- 8m × 4m × 1.5m = 48m³ ✅
- 10m × 3.5m × 1.4m = 49m³ ✅
- 6m × 5m × 1.5m = 45m³ ✅
For larger pools or those without covers/insulation, consider the SP13 (40-70m³) or SP17 (50-85m³) models for better performance.
6. How long does it take to heat up my pool?
Heat-up time depends on pool volume, ambient temperature, and desired temperature rise. As a rough guide for a 45m³ pool:
- Initial heating (20°C → 28°C): 15-27 hours depending on ambient temp
- Daily maintenance (1-2°C recovery): 2-6 hours
Using a solar cover during heating can reduce times by 30-50%. Once at temperature, the inverter technology maintains it very efficiently.
7. What warranty is included?
The Silent-Pro 10 comes with an exceptional warranty:
- 5 years on the complete heat pump unit
- 10 years on the compressor
- 10 years on the heat exchanger
This industry-leading warranty reflects NorSup’s confidence in build quality and durability.
8. Is professional installation required?
Yes, absolutely. Installation must be performed by:
- A qualified electrician (for electrical connections)
- A competent pool engineer (for plumbing integration)
- Or an F-Gas certified installer (for refrigerant systems)
Improper installation can void warranty, create safety hazards, and reduce efficiency. The installation manual provides comprehensive guidance, but professional installation is strongly recommended and often required by local building regulations.
9. How much does it cost to run per hour?
At maximum capacity (9.5 kW output) using 1.39 kW input power:
- Cost per hour: £0.42 – £0.56 (at £0.30-£0.40/kWh)
However, thanks to inverter technology, the Silent-Pro 10 rarely runs at maximum power. In Smart mode for temperature maintenance, typical hourly costs are £0.15-£0.30, making it very affordable to operate.
10. Does it heat and cool?
Yes! The Silent-Pro 10 provides both heating and cooling functions:
- Heating mode for cooler months to reach comfortable swimming temperatures
- Cooling mode during hot summers to prevent water from becoming uncomfortably warm (35°C+)
This dual functionality ensures year-round perfect pool temperature.
11. What maintenance is required?
The Silent-Pro 10 requires minimal maintenance:
Monthly:
- Check water flow and filter cleanliness
- Inspect unit for debris around air intake
Seasonally:
- Clean fins of outdoor coil (if dusty/dirty)
- Check condensate drainage
- Inspect electrical connections (by electrician)
Annually:
- Professional service check recommended
- Refrigerant pressure check (F-Gas certified engineer)
- Full system inspection
The titanium heat exchanger is highly resistant to corrosion and requires no special chemical treatment.
12. Is it compatible with salt water pools?
Yes! The twist-titanium tube heat exchanger is specifically designed to resist corrosion from both chlorine and salt water. The PVC housing provides additional protection, making the Silent-Pro 10 perfect for salt chlorinator systems with salt levels up to 4,000 ppm.
