3. Reach target temperature
4. Turn completely off
5. Temperature drops
6. Turn on at 100% again
7. Cycle repeats constantly ❌

Problems: Wasted energy, temperature fluctuations, high noise, component wear, high electricity spikes

Aqua Inverter Technology:

1. Soft start at low power
2. Gradually increase to required capacity
3. Continuously modulate between 20%-120%
4. Maintain exact temperature
5. Never turn off – just slow down ✅

Benefits: Maximum efficiency, constant temperature, near-silent operation, longer lifespan, lower bills

The Thermodynamic Process 🌡️

Step 1: Air Intake
The fan draws ambient air across the evaporator coil. Even in temperatures down to -15°C, thermal energy is extracted from the air.

Step 2: Heat Extraction
The eco-friendly R32 refrigerant absorbs heat from the air and evaporates into a gas.

Step 3: Compression
The inverter-driven compressor compresses the gas, dramatically increasing its temperature. The inverter adjusts speed to match demand.

Step 4: Heat Transfer
The superheated refrigerant flows through the titanium heat exchanger, transferring heat to your pool water.

Step 5: Expansion
The refrigerant cools and returns to liquid state, ready to repeat the cycle.

The Result: For every 1kW of electricity consumed, the AXR13 produces between 5.3kW to 15kW of heating power depending on conditions – efficiency ratings of 530% to 1,500%!

❓ Frequently Asked Questions

General Questions

Q: What size pool is the AXR13 suitable for?
A: The AXR13 is ideal for pools of 25-50m³ (5,500-11,000 gallons). This typically covers rectangular pools from 8m × 4m up to 10m × 5m, or round pools up to 8m diameter. For smaller pools (under 25m³), consider the AXR10 model. For larger pools (over 50m³), the AXR17 or AXR21 models are recommended.

Q: How long does it take to heat my pool?
A: Heating time depends on multiple factors:

• Pool volume and starting temperature
• Ambient air temperature and humidity
• Whether you use a pool cover
• Target temperature

Example: A 40m³ pool from 18°C to 26°C in 15°C weather:

• With Turbo mode + cover: 48-60 hours
• With Smart mode + cover: 60-72 hours
• Without cover: 2-3× longer

Q: Can the AXR13 also cool my pool in summer?
A: No, the AXR13 is heating-only. If you need cooling capability for indoor pools or very warm climates, you would need a reversible heat pump model. However, most UK pool owners don’t require cooling – simply turning off the heat pump allows natural cooling.

Q: Will it work in winter?
A: Yes! The AXR13 operates in ambient temperatures from -15°C to 43°C. However, efficiency decreases as temperature drops. For optimal efficiency, it’s most economical to use when ambient temperatures are above 10°C. Many UK pool owners swim April through October comfortably.

Q: How noisy is it really?
A: The AXR13 is exceptionally quiet:

• At 10 meters distance: 18.6-26.9 dB(A) – quieter than a whisper
• At 1 meter distance: 38.6-46.9 dB(A) in standard operation
• At 1 meter in Silence mode: 41.3 dB(A) – quieter than a refrigerator

For comparison: Normal conversation is 60 dB(A), a quiet library is 40 dB(A). The backwards airflow design and inverter technology make this one of the quietest heat pumps available.

Q: Does it need to run 24/7?
A: No! The heat pump only needs to run until target temperature is reached, then it can cycle on/off or slow down (in Smart mode). Typical daily runtime:

• Initial heating: 8-12 hours/day
• Maintenance heating: 2-6 hours/day
• With excellent cover: May only need a few hours every couple days

The inverter technology means it can run continuously at very low power levels, which is actually more efficient than on/off cycling.

A:

• Smart Mode (Default): Automatically adjusts from 20%-100% capacity based on conditions for optimal efficiency. Use for daily operation – most economical.
• Turbo Mode: Runs at 120% capacity (13.2kW) for maximum heating speed. Use when you need rapid temperature increase. Auto-switches to Smart when target reached.
• Silence Mode: Limits capacity to 60% maximum for ultra-quiet operation. Perfect for overnight heating in residential areas.

Q: What does COP mean and why does it vary?
A: COP (Coefficient of Performance) measures efficiency:

• COP 8.2 = 8.2kW heat output per 1kW electricity input
• This is 820% efficiency – impossible with traditional heating!

COP varies because heat pumps extract heat from air:

• Warmer air = easier to extract heat = higher COP
• Colder air = harder to extract heat = lower COP
• The inverter adjusts to maintain optimal efficiency at all conditions

• Clean filter regularly (weekly in peak season)
• Check pump basket for debris
• Ensure bypass valve (if present) isn’t restricting flow
• Verify 3-4 m³/h flow rate minimum
• Temperature difference inlet/outlet should be 2-4°C

5. Keep Airflow Unobstructed 🌪️
Clear air = efficient operation:

• Monthly cleaning of evaporator coils (garden hose)
• Keep 2m clearance in front (exhaust)
• Remove leaves, grass clippings promptly
• Don’t position near dusty areas if possible
• Check after storms for debris

6. Set Realistic Target Temperatures 🌡️
Every degree costs money:

• 26-28°C is comfortable for most swimming
• 30°C+ for therapy/spa use only
• Lowering target by 2°C can save 15-20% on costs
• Consider water temperature preferences vs. cost

7. Integrate with Solar Panels ☀️
Perfect synergy:

• Heat pump runs when solar production peaks
• Essentially free heating during sunny days
• Store “heat in the water” like a battery
• Maximizes solar investment ROI

8. Proper Winterization ❄️
Protect your investment:

• Drain all water from unit before freezing temperatures
• Power off and cover unit if storing
• Annual professional inspection recommended
• Follow manual winterization procedure exactly

9. Use Smart Mode as Default 🧠
Let the technology work for you:

• Smart mode automatically optimizes efficiency
• Only use Turbo for rapid heating needs
• Silence mode for overnight/residential consideration
• Trust the inverter to find optimal balance

10. Monitor Performance via App 📊
Knowledge is power:

• Check daily operation for anomalies
• Track efficiency patterns
• Identify issues early
• Learn your pool’s characteristics
• Adjust schedule based on data

BONUS TIP: Consider a solar pre-heater system working in tandem with your heat pump. Solar panels can pre-warm water by 3-5°C “free,” then the heat pump efficiently brings it to target temperature. This combination can reduce running costs by an additional 30-40%!
