📏 Pool Sizing Guide – Is This Heat Pump Right for You?

The Norsup P35X/32 is specifically engineered for large residential and commercial pools. Here’s how to determine if it’s the perfect match for your installation:

Ideal Pool Volumes

Pool Type	Volume Range	Suitability
Minimum Recommended	100 m³	Excellent performance, possibly oversized
Optimal Range	120-150 m³	Perfect match for best efficiency
Maximum Recommended	175 m³	Good performance when well insulated

How to Calculate Your Pool Volume

Rectangular pools: Length (m) × Width (m) × Average Depth (m) = Volume (m³)

Round pools: π × Radius² (m) × Average Depth (m) = Volume (m³)

Irregular shapes: Break into sections and calculate each separately

Example calculations:

🔹 10m × 5m × 1.5m depth = 75 m³ (consider smaller model)
🔹 12m × 6m × 1.5m depth = 108 m³ (excellent match)
🔹 15m × 7m × 1.6m depth = 168 m³ (perfect for this model)

Important Sizing Considerations

⚠️ Pool Insulation Matters – The stated pool volume assumes properly insulated pools with covers. Uninsulated pools or those without covers may require a larger heat pump or will have longer heat-up times.

⚠️ Climate Impact – Pools in colder regions or those used year-round benefit from sizing toward the upper capacity range.

⚠️ Usage Patterns – Frequently used pools or those requiring rapid heating benefit from higher-capacity models.

💡 Professional Tip: For pools at the upper end of the range (160-175m³), consider using a pool cover to improve efficiency and reduce heating costs by up to 50%.

⏱️ Estimated Heat-Up Times for Your Pool

Understanding how quickly your pool will heat helps you plan usage and manage expectations. The tables below provide estimated heat-up times based on the P35X/32’s heating capacity under typical conditions.

⚠️ Important Disclaimers:

These are estimates only based on ideal conditions. Actual heat-up times will vary based on:

• Initial water temperature
• Ambient air temperature and humidity
• Wind conditions and exposure
• Pool insulation quality
• Use of pool cover
• Heat losses through pool walls and floor
• Water circulation system efficiency

Heat-Up Time Estimates – Spring/Autumn Conditions

Assumes 15°C ambient temperature, target 26°C water temperature

Pool Volume	Temperature Rise	Estimated Time to Heat
100 m³	10°C rise (16°C → 26°C)	48-58 hours
120 m³	10°C rise (16°C → 26°C)	58-68 hours
140 m³	10°C rise (16°C → 26°C)	68-78 hours
160 m³	10°C rise (16°C → 26°C)	78-88 hours
175 m³	10°C rise (16°C → 26°C)	85-95 hours

Heat-Up Time Estimates – Summer Conditions

Assumes 27°C ambient temperature, target 28°C water temperature

Pool Volume	Temperature Rise	Estimated Time to Heat
100 m³	6°C rise (22°C → 28°C)	20-24 hours
120 m³	6°C rise (22°C → 28°C)	24-28 hours
140 m³	6°C rise (22°C → 28°C)	28-33 hours
160 m³	6°C rise (22°C → 28°C)	32-37 hours
175 m³	6°C rise (22°C → 28°C)	35-40 hours

Heat-Up Time Calculation Formula

For those who want to calculate their specific scenario:

Time (hours) = (Pool Volume m³ × Temperature Rise °C × 1.16) ÷ Heat Pump kW Output

Example:
150 m³ pool, 8°C temperature rise, using 24 kW average output (A15/W25 conditions):
(150 × 8 × 1.16) ÷ 24 = 58 hours

💡 Pro Tip: Initial heat-up takes the longest. Once at temperature, the heat pump only runs a few hours daily to maintain temperature, consuming minimal energy.

💰 Running Cost Comparison – See Your Savings

One of the most compelling reasons to choose a heat pump over traditional heating is the dramatic reduction in operating costs. Let’s compare:

❓ Frequently Asked Questions

Pool Heating & Performance

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

A: Initial heat-up depends on several factors including pool volume, starting temperature, and ambient conditions. For a 140m³ pool heating from 16°C to 26°C in spring conditions (15°C ambient), expect approximately 68-78 hours. Summer heating (22°C to 28°C in 27°C ambient) takes about 28-33 hours. Using a pool cover can reduce these times by 30-40%. Once at temperature, the heat pump only runs a few hours daily to maintain temperature.

Q: Can this heat pump work in cold weather?

A: Yes! The Norsup P35X/32 is specifically designed for year-round operation and maintains effective heating down to -15°C ambient temperature. Performance gradually reduces in colder conditions (this is normal for all air source heat pumps), but the advanced inverter technology and intelligent defrost system ensure reliable operation throughout the swimming season. In UK climates, it will typically extend your swimming season from April through October.

Q: What’s the difference between COP and efficiency?

A: COP (Coefficient of Performance) is a measure of heat pump efficiency. A COP of 8.0 means the heat pump produces 8 kW of heat for every 1 kW of electricity consumed. This P35X/32 achieves a maximum COP of 16.0 in optimal conditions (27°C ambient, 27°C water) and still maintains 8.2 COP in spring/autumn conditions (15°C ambient, 25°C water). Higher COP = lower running costs.

Q: Is the P35X/32 too large for my 110m³ pool?

A: While technically capable of heating pools down to 100m³, the P35X/32 would be slightly oversized for a 110m³ pool. This isn’t necessarily negative – it means faster heat-up times and less runtime to maintain temperature. However, for pools below 120m³, you might achieve better efficiency with the P26X/32 model (26kW capacity). Oversizing by 10-15% is acceptable and provides headroom for colder climates or poor insulation.

Installation & Setup

Q: Can I install this heat pump myself?

A: While mechanically inclined individuals might handle the physical placement and plumbing connections, electrical connection must be performed by a qualified electrician to comply with UK Building Regulations Part P and IET Wiring Regulations (BS 7671). Improper electrical installation voids warranty and poses serious safety risks. We strongly recommend professional installation of the complete system for optimal performance and safety. DIY installation typically voids the manufacturer warranty.

Q: How far from my pool can the heat pump be located?

A: The heat pump can be installed up to 15 metres from the pool, though 7.5 metres or less is optimal. Every additional metre increases pipe heat loss – roughly 0.6kW per 30 metres of pipe run for each 5°C temperature difference between water and ground. Longer distances require larger pipe diameters and adequate insulation. Keep runs as short as practical and always insulate exposed pipework.

Q: Do I need planning permission to install a pool heat pump?

A: In England and Wales, most pool heat pumps are considered “permitted development” and don’t require planning permission if they meet certain criteria: located more than 1 metre from boundaries, not on the front elevation, and noise output doesn’t exceed permitted levels. However, Listed Buildings, Conservation Areas, and Areas of Outstanding Natural Beauty may have restrictions. Always check with your local planning authority before installation. Scottish and Northern Irish regulations differ – consult local authorities.

Q: What size electrical supply do I need?

A: The P35X/32 requires a dedicated 220-240V single-phase circuit with a minimum 45A breaker and 6mm² cable (live, neutral, and earth). The circuit must include 30mA RCD protection and an isolation switch visible from the heat pump location. Your existing house supply must be adequate – this unit draws 30A when running at full capacity, so ensure your main incoming supply can handle this additional load. Consult a qualified electrician to assess your electrical infrastructure.

Operation & Maintenance

Q: How much maintenance does the heat pump require?

A: Routine maintenance is minimal:

Weekly: Visual inspection for debris around air intake
Monthly: Check condensation drain is clear
Quarterly: Clean air intake fins gently with soft brush or low-pressure water
Annually: Professional service recommended – check refrigerant charge, electrical connections, clean heat exchanger, test all safety systems

Keep vegetation trimmed back, ensure adequate clearances are maintained, and remove the winter cover before starting each season.

Q: Should I turn off the heat pump when the pool isn’t in use?

A: For short periods (1-3 days), it’s more efficient to leave the heat pump maintaining temperature than to let the pool cool and reheat. For longer periods (1+ weeks), you can turn it off but expect 2-3 days to reheat. The timer function lets you automatically restart heating before use. In winter, use the anti-freeze mode to protect the system even when not actively heating.

Q: How noisy is this heat pump really?

A: At 10 metres distance (typical installation to nearest window), the P35X/32 produces 28-38 dB(A) in normal operation – quieter than a quiet library (40 dB). Silent Mode reduces this to just 28 dB(A), equivalent to a whisper. At 1 metre (right next to the unit), noise reaches 48-58 dB(A), similar to moderate rainfall. The dual-speed fans and inverter technology mean it rarely runs at maximum speed, keeping noise levels low during normal operation.

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

A: The heat pump automatically restarts after power restoration, returning to its previous settings. The system includes a 3-minute restart delay to protect the compressor from voltage spikes. All programmable settings (temperature, timers, modes) are stored in non-volatile memory and aren’t lost during power outages. However, WiFi connectivity may need to be re-established if the router restarted.

WiFi & Smart Control

Q: Is the WiFi module easy to set up?

A: Yes! The WiFi module comes pre-installed and the NorsupOne app guides you through setup:

1. Download the free app (iOS or Android)
2. Create an account with your email
3. Press the button on the WiFi module
4. Connect your phone to the module’s network
5. Enter your home WiFi password
6. Scan the QR code on the heat pump
7. Done! Control from anywhere

Setup typically takes 5-10 minutes. The app includes step-by-step visual instructions and troubleshooting tips.

Q: Can multiple people control the heat pump?

A: Yes! After initial setup, you can share access with family members. Each person installs the NorsupOne app and you can grant them control permissions. This is perfect for holiday homes or families where multiple people manage pool maintenance. Each user has their own login and can monitor/control the heat pump independently.

Q: What happens if my internet goes down?

A: The heat pump continues operating normally based on its current settings – internet connectivity isn’t required for basic operation. You’ll lose remote access through the smartphone app until connectivity is restored, but the physical controller on the unit remains fully functional. Once internet returns, the app automatically reconnects and you can resume remote control.

Q: Does the app cost anything?

A: No! The NorsupOne app is completely free to download and use. There are no subscription fees, in-app purchases, or ongoing costs. Full functionality is available to all users at no charge.

Warranty & Support

Q: What warranty is included?

A: The Norsup P35X/32 includes comprehensive warranty coverage:

5-year warranty on the complete heat pump unit (all components)
10-year warranty on the compressor and heat exchanger (critical components)

Warranty coverage requires professional installation by qualified personnel and registration within 30 days of installation. Annual professional servicing is recommended to maintain warranty validity. Full warranty terms are included in the documentation.

Q: What’s NOT covered by warranty?

A: Standard warranty exclusions include:

• Damage from improper installation or electrical supply issues
• Damage from inadequate water flow or poor water chemistry
• Normal wear items (e.g., controller displays after 3 years)
• Damage from freezing due to user error (not enabling anti-freeze mode)
• Cosmetic damage that doesn’t affect functionality
• Damage from unauthorised repairs or modifications
• Commercial or rental pool applications (residential warranty only)

Extended commercial warranties are available separately.

Q: Who provides warranty service and support?

A: Warranty service is provided through the UK distributor network. For technical support, troubleshooting, and warranty claims, contact the retailer where you purchased the unit (Parts4Tubs). They’ll coordinate any necessary service visits with Norsup-approved technicians. Emergency support and spare parts are available throughout the UK. Expected response time for warranty claims is 3-5 working days.

Cost & Efficiency

Q: What are the real-world running costs?

A: Running costs depend on your pool size, climate, usage pattern, and insulation. As a realistic example:

150m³ pool, 6-month season (April-September), maintained at 26°C:

• April-May: £165-215 (initial heat-up + cold weather)
• June-August: £160-210 (maintenance heating, optimal conditions)
• September: £70-90 (less usage, falling temperatures)
• Total season: £420-580

Using a pool cover can reduce costs by 30-50%. Compare this to £2,400-3,200 for electric resistance heating – the heat pump pays for itself in 2-3 seasons.

Q: Is heat pump heating cheaper than solar heating?

A: Solar heating has zero running costs but significant limitations:

Solar pros: Free heat when sun shines, no electricity costs
Solar cons: Ineffective in cloudy weather, large roof space required, only works during daytime, expensive installation (£3,000-6,000)

Heat pump pros: Works day/night, reliable in all weather, smaller space requirement, faster heat-up
Heat pump cons: Electricity costs (though minimal)

Many pool owners find heat pumps more practical for UK climates. Solar can supplement a heat pump for maximum efficiency.

Q: How long until the heat pump pays for itself?

A: Compared to electric resistance heating, the payback period is typically 2-3 swimming seasons based on running cost savings of £1,500-2,500 per year. Compared to gas heating, payback is 3-4 seasons. Higher usage (longer season, larger pool, higher temperature) means faster payback. Factor in reliability, convenience, and extended swimming season – many users consider these benefits equally valuable to cost savings.
