❓ Frequently Asked Questions

What size pool is the Vertigo Fi 240T suitable for?

The 31.23kW capacity is ideal for pools between 80-120 m³ (approximately 17,600-26,400 gallons). This typically covers pools up to 15m x 5m x 2m depth. For pools at the upper end of this range, using a quality pool cover is essential for efficient operation. Smaller pools will benefit from faster heat-up times and even greater efficiency.

How much does it cost to run the Vertigo Fi 240T?

Running costs depend on your pool size, target temperature, and usage pattern. For a typical 80m³ pool maintained at 28°C during the May-September swimming season, expect seasonal running costs of £350-£550 based on average UK electricity rates (£0.24/kWh) and a COP of 7. This is approximately 60-70% cheaper than gas heating and 75-85% cheaper than electric resistance heating.

Can I install this heat pump myself?

No. This is a three-phase 400V appliance that legally requires installation by a qualified electrician in compliance with BS 7671 wiring regulations. The hydraulic connections can be made by a competent person, but the electrical connection must be carried out by a certified professional. Improper installation will void your warranty and may be dangerous.

How long does it take to heat my pool?

Initial heat-up times vary based on pool volume and desired temperature rise. As a rough guide, heating an 80m³ pool from 15°C to 25°C takes approximately 30 hours of operation. Once at temperature, maintenance typically requires only 1-3 hours of daily operation with a pool cover to replace heat lost overnight. See the detailed heat-up time tables above for specific scenarios.

Will the heat pump work in winter?

Yes, the Vertigo Fi 240T operates down to -10°C ambient temperature. However, heating capacity and efficiency reduce as ambient temperature drops. While technically capable of winter operation, most pool owners winterize their pools during the coldest months (December-February) as heating costs become less economical. The heat pump is excellent for extending your swimming season from April through October.

Do I need a pool cover?

While not strictly required, a pool cover is highly recommended and considered essential for efficient operation. Without a cover, pools lose 70% of their heat through evaporation. A quality pool cover can:

• Reduce heating costs by 50-70%
• Cut heat-up times significantly
• Allow use of a smaller capacity heat pump
• Keep debris out of your pool
• Improve chemical efficiency

Bottom line: A pool cover will pay for itself in saved energy costs within one season.

What’s the difference between fixed-speed and inverter heat pumps?

Fixed-speed heat pumps operate at full power then switch off when target temperature is reached—like a light bulb that’s either fully on or fully off. This creates temperature fluctuations, uses more energy, and is noisier.

Full inverter heat pumps (like the Vertigo Fi 240T) continuously adjust compressor speed to match heating demand—like a dimmer switch that maintains perfect brightness. Benefits include:

• 20-40% better energy efficiency
• More stable water temperature
• Quieter operation (no on/off cycling)
• Longer compressor lifespan
• Faster response to temperature changes

How loud is the Vertigo Fi 240T?

The noise level ranges from 29-38 dBA depending on operating mode, measured at 10 meters distance. To put this in perspective:

• 30 dBA = Quiet library whisper
• 40 dBA = Quiet residential area at night
• 50 dBA = Normal conversation

In Silent Mode, the unit operates at just 29 dBA—barely audible from 10 meters away. Most users find it quieter than their pool pump. The vertical discharge also directs sound upward, reducing noise at ground level.

What maintenance does the heat pump require?

The Vertigo Fi 240T is relatively low-maintenance:

Monthly:

• Visual inspection for damage or debris
• Check area around unit is clear of obstructions
• Ensure good airflow around the unit
