❓ Frequently Asked Questions

Q: How long will it take to heat my 60m³ pool from 15°C to 28°C?

A: For a 60m³ pool, you can expect approximately 38-42 hours of operation to achieve a 13°C temperature rise under typical spring conditions (ambient 15-20°C, COP 12-14). Using a pool cover and starting heating 2-3 days before you plan to swim will give the best results. In summer months with warmer ambient temperatures, this time reduces significantly.

Q: Is 28dB really as quiet as claimed? Will it disturb my neighbors?

A: Yes, 28dB(A) is exceptionally quiet—roughly equivalent to a whisper or rustling leaves. At this noise level, the heat pump is barely audible from 5 meters away and virtually silent indoors. In ECO Silence mode, you can comfortably sit next to the unit and have a conversation. This makes it ideal for residential settings where noise could be a concern.

Q: What does “COP up to 20” mean and is that realistic?

A: COP (Coefficient of Performance) measures efficiency—how many units of heat you get per unit of electricity. A COP of 20 means you get 20kW of heating for every 1kW of electricity used. However, this maximum figure is achieved only under perfect laboratory conditions (typically 28°C ambient/28°C water). In real-world conditions, expect COP values of 10-16, which is still incredibly efficient—meaning you get 10-16 times more heat output than electricity input.

Q: Can I use this heat pump in winter or for indoor pools?

A: This All-Season model is designed for extended outdoor pool use from March to November with heat tracing protection down to -5°C ambient. While technically capable of winter operation, efficiency drops significantly below 5°C, and it’s not recommended for continuous winter use in cold climates. For indoor pools, special considerations apply—contact us to discuss indoor installation requirements, as ventilation and humidity control become important factors.

Q: Why do I need 3-phase power? Can I use single-phase instead?

A: The 24kW model requires 3-phase power (400V) due to its high heating capacity. Three-phase power distributes the electrical load more evenly and efficiently for larger units. If you only have single-phase power available, consider the VBIV 20kW 1-phase model instead. Check with your electrician to confirm what power supply is available at your property before purchasing.

Q: What maintenance does this heat pump require?

A: Maintenance is minimal but important:

• Monthly: Visual inspection, clear any debris from air intake
• Before season: Clean coils with water, check all connections
• After season: Clean unit, install winter cover (included)
• Annually: Professional service recommended (check refrigerant, electrical connections, clean heat exchanger)

The 5-inch touchscreen displays operation history and alerts you to any maintenance needs.

Q: How does the WiFi module work? What can I control remotely?

A: The included WiFi module connects your heat pump to your home network, allowing smartphone/tablet control through a dedicated app. You can remotely:

• View current pool and ambient temperature
• Adjust target temperature
• Set heating schedules and timers

Q: What warranty coverage do I get?

A: The VBIV heat pump comes with up to 5 years warranty coverage when properly registered after installation. This covers manufacturing defects and component failures. Warranty terms require professional installation and annual maintenance. Extended warranty options may be available—contact us for details.

Q: How much does it cost to run compared to my current gas boiler?

A: Heat pumps are typically 3-5 times more efficient than gas boilers for pool heating. While gas costs vary by region, a heat pump running at COP 13 converts £1 of electricity into £13 worth of heat. Even with electricity costing 3-4 times more per kWh than gas, you still save 30-60% on running costs. Plus, heat pumps require less maintenance and have longer service lives than gas boilers.

Q: Can I heat my pool faster by setting the temperature higher than my target?

A: No—this is a common misconception. The heat pump delivers maximum heating output continuously until the target temperature is reached, regardless of how high you set it. Setting the target to 35°C when you want 28°C won’t speed up the process; it will just cause the unit to overshoot and waste energy. For faster initial heating, use “Boost Mode” which maximizes output, or consider the 29kW model for larger pools.

Q: What happens if there’s a power cut while the heat pump is running?

A: The heat pump has built-in protection and will safely shut down during power loss. When power is restored, it will automatically restart and resume normal operation using your saved settings. All your programmed schedules, temperature targets, and WiFi settings are stored in non-volatile memory, so nothing is lost. The system includes a 3-minute compressor protection delay to prevent damage from rapid power cycling.

Q: Is professional installation required or can I install it myself?

A: While plumbing connections can be completed by experienced DIYers, electrical installation must be performed by a qualified electrician due to 3-phase power requirements and safety regulations. Improper installation voids warranty and can be dangerous. We strongly recommend professional installation for both plumbing and electrical work to ensure optimal performance, safety, and warranty coverage. Many installers offer package deals for complete installation.
