⏱️ Heating Performance & Time Estimates
Understanding how quickly your pool will heat up helps you plan your swimming schedule. Below are estimated heating times based on common pool sizes and temperature increases.
Estimated Heat-Up Times
| Pool Size | Water Volume | Temperature Rise | Estimated Time* |
|---|---|---|---|
| 10ft diameter | 9m³ (2,000 gal) | 5°C (9°F) | 10-12 hours |
| 10ft diameter | 9m³ (2,000 gal) | 10°C (18°F) | 20-24 hours |
| 12ft diameter | 13m³ (2,880 gal) | 5°C (9°F) | 15-18 hours |
| 12ft diameter | 13m³ (2,880 gal) | 10°C (18°F) | 30-36 hours |
| 15ft diameter | 20m³ (4,400 gal) | 5°C (9°F) | 23-27 hours |
| 15ft diameter | 20m³ (4,400 gal) | 10°C (18°F) | 46-54 hours |
⚠️ Important Disclaimer: These are theoretical estimates calculated using standard formulas. Actual heating times will vary based on ambient air temperature, humidity, wind conditions, pool cover usage, insulation, and starting water temperature. Heat pumps work most efficiently when ambient temperatures are above 10°C. Using a pool cover when not swimming can reduce heating times by 30-50%.
Heat-Up Time Calculation
Want to calculate heating time for your specific pool? Use this formula:
Time (hours) = (Pool Volume in m³ × Temperature Rise in °C × 1.16) ÷ 5kW
Example: A 12ft pool (13m³) heating from 18°C to 25°C (7°C rise): (13 × 7 × 1.16) ÷ 5 = 21.2 hours
💰 Running Cost Comparison
See how much you could save compared to traditional electric heaters:
| Heating Method | Typical Daily Cost* | Monthly Cost* (May-Sept) | Season Savings vs Electric |
|---|---|---|---|
| PoolStyle 5kW Heat Pump | £1.50 – £3.00 | £45 – £90 | Baseline |
| Traditional Electric Heater (18kW) | £12.00 – £15.00 | £360 – £450 | Save £315 – £360/month |
| Gas Heater | £8.00 – £12.00 | £240 – £360 | Save £195 – £270/month |
Based on running 6-8 hours daily, UK electricity rates of £0.30/kWh, and typical May-September usage. Your actual costs will vary based on usage patterns, ambient temperature, pool cover use, and energy tariffs.
💡 Cost-Saving Tip: Use a solar pool cover to retain heat overnight and reduce running times by up to 50%. This single investment can save you £20-45 per month in heating costs.

❓ Frequently Asked Questions
How much electricity does this heat pump use?
The PoolStyle 5kW heat pump typically consumes around 1-1.2kW of electricity to produce 5kW of heating power. This 5:1 efficiency ratio means for every £1 you spend on electricity, you receive £5 worth of heating – making it up to 75% cheaper to run than traditional electric heaters. Daily running costs typically range from £1.50-£3.00 depending on how long it operates and your electricity tariff.
Will this heat pump work for my pool?
This heat pump is designed for pools up to 15ft in diameter, which equates to approximately 20-25m³ (4,400-5,500 gallons) of water volume. If your pool is larger than this, the heat pump will struggle to maintain temperature efficiently, and you should consider a more powerful model (8kW, 12kW, or higher). For pools smaller than 12ft diameter, this unit is perfect and may even be slightly oversized, giving you faster heating times.
How long will it take to heat my pool initially?
Initial heat-up time depends on several factors: your pool size, starting water temperature, desired temperature, and ambient air conditions. As a general guide, expect 10-12 hours for a 10ft pool with a 5°C temperature rise, up to 46-54 hours for a maximum 15ft pool with a 10°C rise. Using a solar pool cover can reduce these times by 30-50%. Once at temperature, maintaining warmth requires much less time.
Can I use an extension lead to power the heat pump?
No – absolutely not. The manufacturer explicitly states that direct power connection is required. Extension leads can cause voltage drop, overheating, and potentially dangerous electrical issues with equipment drawing continuous power like heat pumps. You must plug directly into a properly rated wall socket. If your socket isn’t close enough, have a qualified electrician install an outdoor socket in an appropriate location.
Does the heat pump work in cold weather?
Heat pumps work by extracting warmth from ambient air, so their efficiency decreases as air temperature drops. This unit operates best in temperatures above 15°C and can function down to about 10°C, though with reduced efficiency. Below 10°C, heating times become impractically long and efficiency drops significantly. Heat pumps are not designed for winter pool heating in the UK – they’re best suited for extending your swimming season from late spring through early autumn (May-September).
Do I need to run the heat pump continuously?
No. Once your pool reaches the desired temperature, the heat pump will cycle on and off to maintain that temperature, rather than running continuously. In peak summer with a pool cover, you might only need to run it 2-4 hours per day. In cooler weather or without a cover, expect 6-8 hours daily. The built-in thermostat automatically manages operation to maintain your set temperature.
What maintenance does the heat pump require?
Heat pump maintenance is minimal but important:
- Weekly: Visual check for debris, leaves, or obstructions around air intake
- Monthly: Clean or rinse the air filter/grille area
- Seasonally: Professional check of refrigerant levels and electrical connections
- Annually: Full service by qualified technician (recommended)
- Off-season: Drain water from unit, cover, and store in dry location if not in use
Proper maintenance ensures optimal performance and longevity.
Is a pool cover really necessary?
While not strictly necessary, a pool cover is highly recommended and will transform your heat pump’s effectiveness. Without a cover, you can lose 50-70% of your heat overnight through evaporation. A solar pool cover reduces heat loss by up to 95%, cuts heating times in half, reduces running costs significantly, and helps maintain temperature overnight. For the cost of £30-80, a pool cover is the single best investment you can make alongside your heat pump.
Can I install this heat pump myself?
Yes, if you’re reasonably handy. The electrical connection is plug-and-play (just plug into an outlet), and the plumbing connections are straightforward for anyone with basic DIY skills. You’ll need to:
- Position the unit on a level surface
- Connect inlet and outlet pipes (1.25″ or 1.5″)
- Plug into power outlet
- Set your desired temperature
However, if you’re uncomfortable with plumbing connections or don’t have an appropriately located power outlet, consider professional installation. Many pool equipment suppliers offer installation services.
What’s the difference between this and an electric pool heater?
Heat Pump (this unit):
- Uses 1-1.2kW to produce 5kW of heat
- Up to 75% cheaper to run
- Slower initial heat-up (10-50+ hours)
- Works best in temperatures above 10°C
- Larger upfront cost
- Best for season-long pool maintenance
Electric Heater:
- Uses 18kW to produce 18kW of heat
- Expensive to run (£12-15 daily)
- Very fast heat-up (6-12 hours)
- Works in any temperature
- Lower upfront cost
- Best for occasional quick heating
Most pool owners find heat pumps far more economical for regular season use.
Does the 2-year warranty cover everything?
The 2-year manufacturer warranty covers defects in materials and workmanship under normal use. Warranty service is handled directly through PoolStyle. The warranty typically doesn’t cover:
- Damage from improper installation
- Use with extension leads (explicitly prohibited)
- Damage from freezing (failure to winterize)
- Normal wear and tear
- Damage from power surges
Always review the full warranty documentation included with your unit for complete terms and conditions.
How noisy is the heat pump?
Specific decibel ratings aren’t provided for this model, but mini heat pumps of this size typically operate at 40-50 dB – roughly equivalent to a quiet conversation or modern refrigerator. The fan and compressor create some noise, but it’s generally not intrusive when positioned appropriately. Avoid placing directly next to bedroom windows or quiet seating areas if noise sensitivity is a concern.
