❓ Frequently Asked Questions

1. What size pool is this 18kW heat pump suitable for?

The VBEX 18kW is designed for pools with surface areas of 35-75 square metres. For pool volumes, this translates to approximately 55-125 cubic metres. The exact suitability depends on your local climate, how well-insulated your pool is, and whether you use a pool cover. In general, this model works best for larger residential pools or small commercial installations where reliable, efficient heating is essential.

2. How much does it cost to run compared to an electric heater?

The VBEX heat pump is dramatically more efficient than electric resistance heaters. While an electric heater consumes 1 kWh of electricity to produce 1 kWh of heat, a heat pump typically produces 4-6 kWh of heat for every 1 kWh consumed (COP of 4-6). This means running costs are 60-80% lower than electric heating. For a typical season, expect to pay £600-£900 versus £2,500-£3,500 for electric heating – a saving of nearly £2,000 per year!

3. Can I control the heat pump remotely with the WiFi feature?

Yes! The built-in WiFi module allows you to control and monitor your heat pump from anywhere using your smartphone. You can adjust temperature settings, switch between operating modes, set heating schedules, monitor real-time performance and energy consumption, and receive alerts if any issues arise. This is perfect for pre-heating your pool before coming home or managing the system while you’re away on holiday.

4. How quiet is this heat pump during operation?

The VBEX is designed for ultra-quiet operation and is significantly quieter than conventional pool heaters of the same capacity. The Mitsubishi compressor operates with minimal vibration, the full-inverter technology reduces noise during low-demand periods (often running at just 25-50% capacity), and the acoustically optimized housing minimizes sound propagation. While we don’t have specific decibel ratings, customers consistently report that it’s whisper-quiet – ideal for residential settings where noise is a concern.

5. What’s the difference between full-inverter and standard heat pumps?

Full-inverter technology is a significant upgrade over traditional on/off heat pumps. Here’s the difference:

Standard Heat Pump: Works like a light switch – either fully on (100% power) or completely off. This constant cycling wastes energy, causes temperature fluctuations, increases wear on components, and results in higher electricity bills.

Full-Inverter Heat Pump (VBEX): Continuously adjusts output from 25% to 100% to match your exact heating needs. This means lower energy consumption (up to 30% savings), more stable water temperature, reduced wear and tear (longer lifespan), quieter operation, and faster payback through lower running costs.

6. Will this work in winter or colder weather?

Air source heat pumps like the VBEX work most efficiently when ambient temperatures are above 15°C. Performance gradually decreases as temperatures drop, and most models struggle below 5-10°C. This means:

• Spring/Summer/Early Autumn (15°C+): Excellent performance, optimal efficiency
• Late Autumn (10-15°C): Good performance, slightly reduced efficiency
• Winter (Below 10°C): Reduced efficiency, may not maintain temperature

For year-round swimming in the UK, you may need supplementary heating during the coldest months, or consider a model with enhanced low-temperature performance. The included winter cover helps protect the unit during periods when it’s not in use.

7. Is a pool cover necessary, or will the heat pump work without one?

While the heat pump will function without a cover, using a pool cover is absolutely essential for efficiency and cost-effectiveness. Here’s why:

• Reduces heat loss overnight by 70-90%
• Cuts heat-up times in half
• Lowers running costs by 50-60%
• Reduces water evaporation
• Keeps debris out of the pool

Without a cover, your heat pump will run continuously trying to replace lost heat, dramatically increasing electricity costs. A quality pool cover typically pays for itself in energy savings within a single season.

8. What maintenance does the heat pump require?

The VBEX is designed for minimal maintenance, but regular care ensures optimal performance:

Monthly:

• Visually inspect for debris around the unit
• Check that air intake and outlet are clear

Every 3 Months:

• Clean or rinse the air filter (if accessible)
• Check for any unusual noises or vibrations
• Ensure condensate drain is clear

Annually (Before Season):

• Professional service inspection recommended
• Check refrigerant levels and electrical connections
• Clean heat exchanger fins if needed
• Test all controls and safety features

End of Season:

• Clean the unit thoroughly
• Install the included winter cover
• Disconnect power if not in use

With proper care, the Mitsubishi compressor and quality components should provide 10-15 years of reliable service.

9. Do I need a professional installer, or can I install it myself?

Professional installation is strongly recommended and often required for warranty coverage. Here’s why:

• Electrical Work: This is a 1-phase electrical appliance requiring proper circuit protection, cabling, and connection by a qualified electrician
• Plumbing Connections: Proper integration with your pool’s filtration system
• Refrigerant System: Any issues with refrigerant require certified handling
• Warranty Protection: Many manufacturers require professional installation for warranty validity
• Safety: Incorrect installation can be dangerous and reduce efficiency

While experienced DIYers may handle some aspects, electrical connection and commissioning should always be done by qualified professionals.
