🏊 Pool Sizing Guide

Recommended Pool Volumes:

Pool Volume	Suitability
80 – 90 m³	✅ Ideal
90 – 100 m³	✅ Excellent
100 – 115 m³	✅ Very Good
115 – 125 m³	⚠️ Adequate (may require longer heating times)

Pool Volume Calculation:

• Rectangular Pool: Length (m) × Width (m) × Average Depth (m)
• Circular Pool: Radius² (m) × 3.14 × Average Depth (m)

💡 Pro Tip: Always use a pool cover when not swimming. This prevents up to 80% of heat loss through evaporation and dramatically reduces heating times and running costs.

⏱️ Estimated Heat-Up Times

The table below provides estimated times to heat various pool volumes. These are calculated using the formula:

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

Heat-Up Time Estimates (21.2kW Output)

Pool Volume (m³)	5°C Rise	10°C Rise	15°C Rise
80 m³	22 hours	44 hours	65 hours
90 m³	24 hours	49 hours	73 hours
100 m³	27 hours	55 hours	82 hours
110 m³	30 hours	60 hours	90 hours
115 m³	31 hours	63 hours	94 hours

Heat-Up Time Estimates (15.83kW Output at 15°C Air Temp)

Pool Volume (m³)	5°C Rise	10°C Rise	15°C Rise
80 m³	29 hours	59 hours	88 hours
90 m³	33 hours	66 hours	99 hours
100 m³	37 hours	73 hours	110 hours
110 m³	40 hours	81 hours	121 hours
115 m³	42 hours	84 hours	126 hours

⚠️ Important Disclaimers:

• These are estimates only and actual times will vary based on multiple factors
• Calculations assume optimal conditions with pool cover when not in use
• Factors affecting actual performance: wind exposure, humidity, initial water temperature, ambient air temperature, pool insulation, cover usage, and heat loss overnight
• With a pool cover: Times may be 30-50% faster
• Without a pool cover: Times may be 100-200% longer due to evaporation
• Heat-up times are cumulative (not per 24 hours) and represent total heating time required

❓ Frequently Asked Questions

General Questions

Q: What size pool is this heat pump suitable for?
A: The Poolex Vertigo Fi 155 is designed for pools between 80-115 m³. For a typical rectangular pool, this equates to approximately 8m x 4m x 1.5m depth. It can handle slightly larger pools but heating times will increase.

Q: How long does it take to heat my pool?
A: This depends on several factors including pool volume, desired temperature rise, ambient conditions, and whether you use a pool cover. As a guide, expect 1-2°C temperature rise per day for a 100m³ covered pool in optimal conditions. See our heat-up time tables above for detailed estimates.

Q: Can this heat pump cool my pool as well as heat it?
A: Yes! The Vertigo Fi 155 has a reversible cooling function with 10.29kW cooling capacity. This is perfect for hot summer days when your pool temperature exceeds 28°C and you want refreshing water.

Q: How much does it cost to run?
A: Running costs depend on usage, climate, and electricity prices. At UK rates (£0.30/kWh), expect approximately £0.60-£0.98 per hour of operation. For a typical swimming season (May-September), total costs range from £400-£800 for a covered 100m³ pool.

Q: Will this heat pump work in winter?
A: Yes, it operates down to -10°C ambient temperature. However, efficiency decreases at lower temperatures. For optimal performance, we recommend 15°C+ ambient temperatures. The unit has automatic antifreeze protection when on standby.

Installation Questions

Q: Can I install this myself?
A: No. Electrical installation MUST be performed by a qualified electrician to comply with regulations and maintain warranty validity. Hydraulic connections require plumbing knowledge and proper technique.

Q: Do I need a bypass kit?
A: While not strictly mandatory, a bypass kit is highly recommended. It allows you to regulate water flow, isolate the heat pump for maintenance without stopping circulation, and optimize performance. This protects your investment.

Q: What electrical supply do I need?
A: You need a dedicated 230V single-phase supply with a 25A Type C circuit breaker and 6mm² cable (for runs up to 10m). A 30mA RCD is mandatory upstream for safety.

Q: How much space do I need around the heat pump?
A: Minimum clearances: 1m in front, 0.5m on sides and rear, 2.5m above for vertical air discharge. The compact 575 x 575mm footprint means it fits where horizontal units won’t.

Q: Can I install it indoors?
A: The heat pump is designed for outdoor installation. It requires adequate ventilation and air circulation. Indoor installation is not recommended unless in a very well-ventilated technical room with proper air inlet/outlet provisions.

Operation Questions

Q: How do I connect to WiFi?
A: Download the “Poolex” or “Smart Life” app, create an account, and follow the in-app pairing instructions. You’ll need to press specific button combinations on the heat pump controller to enable pairing mode. Full instructions are in the manual and app.

Q: What’s the difference between the operating modes?
A: BOOST = Maximum heating speed (21.2kW), ECO = Balanced performance, SILENT = Quietest operation (13.11kW), AUTO = Unit intelligently selects optimal mode. Choose based on your priorities: speed, noise, or efficiency.

Q: How loud is it really?
A: At 10 meters distance: 24-32 dBA (quieter than a whisper or library). At 1 meter: 42-52 dBA (similar to quiet conversation). SILENT mode is even quieter. This makes it one of the quietest heat pumps available.

Q: Do I need to maintain it?
A: Annual professional maintenance is recommended. User maintenance includes: keeping the evaporator clean (vacuum with soft brush), checking water flow monthly, ensuring proper water chemistry (pH 6.9-8.0), and winterizing if not in use during freezing conditions.

Q: What is COP and why does it matter?
A: COP (Coefficient of Performance) measures efficiency. A COP of 15 means the heat pump produces 15kW of heat for every 1kW of electricity consumed. Higher COP = lower running costs. The Vertigo Fi 155 achieves up to COP 15.17 in optimal conditions.

Warranty & Support

Q: What does the warranty cover?
A: 5 years on the heat pump unit, 7 years on compressor (parts only after year 5), 15 years on titanium coil against corrosion (parts only after year 5). Covers manufacturing defects and material faults. Excludes improper installation, maintenance neglect, frost damage, or misuse.
