🏊 Pool Sizing Guide – Is This Heat Pump Right For You?

Choosing the correct heat pump size is crucial for efficient heating and cost-effective operation. Here’s how to determine if the VBIV H8 20kW is ideal for your pool:

Recommended Pool Sizes

Pool Volume	Pool Dimensions (Example)	Suitability
40-55 m³	8m x 4m x 1.5m depth	✅ Ideal – Fast heating
55-75 m³	10m x 5m x 1.5m depth	✅ Recommended – Efficient
75-100 m³	12m x 6m x 1.5m depth	✅ Suitable – Extended heating time
100+ m³	Larger pools	⚠️ Consider additional unit or larger model

💡 Pro Tip: For pools with biological filters, reduce the maximum volume by 20m³ for optimal performance.

⏱️ Estimated Heat-Up Times

Understanding how quickly your pool will heat helps you plan ahead. Below are estimated heat-up times based on real-world conditions.

Heat-Up Time Calculator

Formula Used:
Time (hours) = (Pool Volume × Temperature Rise × 1.16) ÷ Heat Pump kW Rating

Estimated Times for Various Pool Sizes

Conditions: Starting from 15°C ambient air, heating water from 18°C to target temperature

Small Pool (50m³)

Target Temp	Temp Rise	Est. Time @ 15kW*	Est. Time @ 10kW*
24°C	6°C	23 hours	35 hours
26°C	8°C	31 hours	46 hours
28°C	10°C	39 hours	58 hours

Medium Pool (70m³)

Target Temp	Temp Rise	Est. Time @ 15kW*	Est. Time @ 10kW*
24°C	6°C	32 hours	49 hours
26°C	8°C	43 hours	65 hours
28°C	10°C	54 hours	81 hours

Large Pool (90m³)

Target Temp	Temp Rise	Est. Time @ 15kW*	Est. Time @ 10kW*
24°C	6°C	42 hours	63 hours
26°C	8°C	55 hours	83 hours
28°C	10°C	69 hours	104 hours

*Note: Heat pump output varies with ambient temperature. 15kW typical at 15°C air temp, 10kW at colder conditions, up to 20kW in optimal conditions (24°C air).

⚠️ Important Disclaimers:

• These are estimates only based on theoretical calculations
• Actual times vary significantly based on: ambient air temperature, humidity, wind speed, pool cover usage, insulation, sun exposure, and starting water temperature
• Using a pool cover can reduce heating time by 30-50%
• Heating times increase significantly in temperatures below 10°C
• For best results, heat pool gradually over several days rather than rapid heating

❓ Frequently Asked Questions

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

The VBIV H8 20kW is designed for pools between 45-100m³ (roughly 10,000-22,000 gallons). For optimal performance and faster heating, we recommend pools in the 50-75m³ range. If your pool has a biological filter section, the maximum recommended volume is 55m³.

Quick Size Check:
Calculate your pool volume: Length (m) × Width (m) × Average Depth (m) = Volume (m³)

2. How long will it take to heat my pool?

Initial heat-up from cold varies significantly based on conditions:

• 50m³ pool: 24-48 hours to raise from 18°C to 26°C (with cover)
• 70m³ pool: 36-72 hours for same temperature rise
• 90m³ pool: 48-96 hours for same temperature rise

Key Factors:

• Ambient air temperature (warmer = faster)
• Use of pool cover (essential for efficiency)
• Starting water temperature
• Wind exposure and sun exposure

💡 Top Tip: Once at target temperature, maintaining it requires far less energy. Plan to heat your pool over 2-3 days when first opening, then maintain daily.

3. Can this heat pump work in winter?

Yes, but with important caveats:

✅ Operational Range: -15°C to +43°C air temperature
✅ Built-in Protection: Heat tracing prevents freeze damage
✅ Winter Cover Included: For off-season protection

Reality Check:

• Below 5°C: Output drops significantly, running costs increase dramatically
• Below 0°C: COP may drop to 2-3, similar efficiency to electric heating
• Recommendation: Heat pump is best used March-November
• Winter swimming: Possible but expensive; consider solar cover or pool enclosure

The unit CAN run in winter, but it’s not cost-effective for regular heating below 5°C ambient.

4. What’s the difference between inverter and non-inverter heat pumps?

Standard On/Off Heat Pumps:

• Run at full power then shut off
• Frequent cycling = wear and tear
• Temperature fluctuations
• Higher electricity spikes
• COP typically 4-6

VBIV H8 Full Inverter Heat Pump:

• Variable speed compressor (10-100% capacity)
• Runs continuously at optimal speed
• Consistent water temperature
• Soft-start reduces electrical stress
• COP up to 20 in ideal conditions
• 30-40% more efficient
• Quieter operation
• Longer lifespan

Bottom Line: Inverter technology pays for itself through energy savings within 2-3 seasons.

5. How much will it cost to run?

Based on UK electricity rates (~£0.28/kWh) and maintaining 26°C:

Typical Daily Running Costs:

• May/September: £1.50-£2.50/day (10-12 hours runtime)
• June-August: £1.00-£2.00/day (6-8 hours runtime)
• With Pool Cover: Reduce costs by 30-50%

Estimated Seasonal Costs (6 months):

• Without cover: £400-£500
• With cover: £250-£350

Variables Affecting Cost:

• Target temperature (each degree costs ~15% more)
• Pool cover usage (most important factor!)
• Ambient temperature
• Pool insulation
• Wind exposure

6. Do I need a pool cover?

Absolutely yes! A pool cover is the single most important accessory:

Without Cover:

• 70% of heat loss through evaporation
• Double your heating costs
• Heat pump runs twice as long
• Temperature drops 2-4°C overnight

With Cover:

• Reduce heat loss by 70-90%
• Cut running costs by 30-50%
• Maintain temperature overnight
• Extend swimming season
• Faster initial heat-up
• Payback period: 1 season

Types of Covers:

• Bubble/Solar Cover: Best value, adds some passive heating
• Automatic Cover: Ultimate convenience, excellent insulation
• Thermal Cover: Maximum heat retention for cooler months

7. What maintenance does it require?

The VBIV H8 is designed for low maintenance, but regular checks ensure optimal performance:

Weekly Checks:

• Clean debris from air inlet grille
• Check water flow rate (6.7 m³/h minimum)
• Inspect for unusual noise or vibration

Monthly Tasks:

• Clean or replace pool filter
• Check electrical connections (visual only)
• Test WiFi connectivity

Seasonal Maintenance:

• Before Season: Remove winter cover, check refrigerant pressure (professional)
• End of Season: Install winter cover, drain condensate, winterize if below -5°C expected
• Annual Service: Professional inspection recommended (check warranty requirements)

Professional Service Recommended:

• Every 1-2 years for optimal performance
• Check refrigerant levels
• Inspect electrical components
• Clean evaporator coils
• Update software if available

Yes! The VBIV H8 is suitable for indoor pool heating with special considerations:

Requirements for Indoor Use:

• Adequate fresh air supply to the heat pump location
• Proper ventilation (air changes per hour)
• Dehumidification system (separate unit required)
• Condensate drainage
• May need ducting for air intake/outlet

Benefits for Indoor Pools:

• More consistent ambient temperature = higher COP
• Protected from weather = longer lifespan
• Year-round use possible
• No winter protection needed

Important: High humidity environments require careful planning. Please contact us for indoor pool application guidance – we can help spec the right configuration.

11. How does it compare to solar heating?

Solar Heating: ✅ Free operating cost
✅ Eco-friendly
❌ Weather dependent
❌ Large roof space required
❌ Expensive installation
❌ Limited season extension

VBIV H8 Heat Pump: ✅ Consistent heating regardless of weather
✅ Compact footprint
✅ Extends season March-November
✅ Predictable performance
❌ Running costs (but very efficient)

Best Solution: Combine both! Solar for summer boost, heat pump for shoulder seasons and cloudy days.

12. What happens during a power cut?

Auto-Restart Function:

• Heat pump automatically restarts after power restoration
• Returns to previous settings
• No manual intervention required

During Outage:

• All settings stored in memory
• No damage to unit
• Pool temperature will drop gradually
