The Pro Elyo Touch PET-19 is designed for large residential and commercial pools. Use this guide to determine if this model suits your needs:

Recommended Pool Volumes

Pool Size	Volume	Suitability
Small pools	Up to 40m³	✅ Excellent (rapid heating)
Medium pools	40-65m³	✅ Ideal (balanced performance)
Large pools	65-90m³	✅ Recommended (optimal efficiency)
Very large pools	90-120m³	⚠️ Acceptable (slower heat-up)

Common Pool Dimensions

Pool Dimensions (L×W×D)	Approximate Volume	Recommendation
6m × 3m × 1.5m	27m³	✅ Excellent match
8m × 4m × 1.5m	48m³	✅ Perfect choice
10m × 4m × 1.5m	60m³	✅ Ideal capacity
10m × 5m × 1.5m	75m³	✅ Recommended
12m × 5m × 1.5m	90m³	✅ Maximum recommended

💡 Pro Tip: For pools over 90m³, consider the larger PET-25 (24kW) model for faster heating and better temperature maintenance.

Estimated Heat-Up Times ⏱️

Understanding how quickly your pool will heat helps you plan ahead. Below are estimated times to raise your pool temperature using the PET-19.

⚠️ Important Disclaimer: These are theoretical estimates based on the formula: Time (hours) = (Pool Volume × Temperature Rise × 1.16) ÷ Heat Pump kW Rating. Actual times vary based on:

• Ambient air temperature
• Pool insulation and cover usage
• Wind exposure and evaporation
• Starting water temperature
• Heat losses overnight

For most accurate results: Use a pool cover when not in use to reduce heat loss by up to 70%.

Heat-Up Time Estimates (Optimal Conditions: 28°C Air)

Using 19.8kW maximum output at optimal conditions:

Pool Volume	5°C Rise	8°C Rise	10°C Rise
40m³	12 hours	19 hours	23 hours
50m³	15 hours	23 hours	29 hours
60m³	17 hours	28 hours	35 hours
75m³	22 hours	35 hours	44 hours
90m³	26 hours	42 hours	53 hours

Heat-Up Time Estimates (Moderate Conditions: 15°C Air)

Using 13.0kW output at cooler ambient temperatures:

Pool Volume	5°C Rise	8°C Rise	10°C Rise
40m³	18 hours	29 hours	36 hours
50m³	22 hours	36 hours	45 hours
60m³	27 hours	43 hours	54 hours
75m³	33 hours	53 hours	67 hours
90m³	40 hours	64 hours	80 hours

💡 Real-World Advice:

• Plan for 2-4 days to bring your pool from cold to comfortable at the start of the season
• Once at temperature, the heat pump maintains it easily with minimal running time
• Use Boost Mode for initial heat-up, then switch to Smart Mode for efficient maintenance
• Always use a pool cover to dramatically reduce heat-up times and running costs

Swimming Pool Heat Pump FAQs ❓

General Questions

Q: How does a heat pump work?

A: Heat pumps don’t generate heat—they transfer it. The PET-19 extracts thermal energy from the outdoor air and concentrates it to heat your pool water. Even at -20°C, there’s sufficient thermal energy in the air for the heat pump to capture and transfer. This process is incredibly efficient, delivering 4.5-6 times more heat energy than the electricity consumed.

Q: Will the PET-19 work with my pool?

A: The PET-19 is compatible with virtually all pool types: above-ground, in-ground, vinyl-lined, fibreglass, concrete, and tiled pools. It works with both freshwater and saltwater systems (up to 6000 ppm) thanks to its titanium heat exchanger. Suitable for pools between 40-90m³ for optimal performance.

Q: How long does it take to heat my pool?

A: This depends on your pool size, starting temperature, and weather conditions. As a general guide:

• Initial heat-up (start of season, 10°C rise): 2-4 days for a 60m³ pool
• Daily maintenance (once at temperature): 2-6 hours depending on weather
• Recovery after 2-3 days without heating: 12-24 hours

Using a pool cover dramatically reduces heating times and maintains temperature better.

Performance & Efficiency

Q: What does COP mean and why is it important?

A: COP (Coefficient of Performance) is the ratio of heat output to electricity input. The PET-19 achieves a COP of 6.0 at optimal conditions, meaning it produces 6kW of heat for every 1kW of electricity used. This is why heat pumps cost 80% less to run than traditional electric heaters. Higher COP = greater efficiency = lower running costs.

Q: How much will it cost to run?

A: Running costs depend on your pool size, desired temperature, climate, and electricity rates. For a typical 60m³ pool used 6 months per year:

• Annual cost: £600-£900 (with proper pool cover)
• Daily maintenance: £1-£3 per day once at temperature
• vs Electric Heater: Save £1,500+ per year
• Payback period: 2-3 years

Q: Can it heat my pool in winter?

A: Yes! The PET-19 operates effectively down to -20°C ambient temperature. However, heating performance decreases as temperatures drop. For year-round swimming in cold climates, we recommend:

• Using a high-quality pool cover (reduces heat loss by 70%)
• Considering pool enclosure or bubble cover
• Realistic temperature expectations (28°C may not be achievable when ambient is -10°C)
• Understanding that runtime and costs increase in very cold weather

In UK winter conditions (0-10°C), the PET-19 will maintain comfortable pool temperatures for covered pools.

Installation & Technical

Q: Can I install this myself?

A: While mechanically-minded homeowners can handle the hydraulic connections, professional installation is strongly recommended for several reasons:

• Electrical connection requires Part P qualified electrician
• Correct sizing of circuit breaker and cabling is critical for safety
• Proper positioning affects efficiency and noise levels
• Refrigerant system must not be disturbed (sealed unit)
• Warranty may require professional installation
• Bypass kit installation ensures proper winter drainage

Typical professional installation takes 4-6 hours and costs £300-600.

Q: Do I need a bypass kit?

A: While not absolutely required, a bypass kit is highly recommended because it:

• Allows complete drainage in winter to prevent freeze damage
• Enables easy servicing without draining the entire pool
• Provides better flow control for optimal efficiency
• Protects your heat pump during off-season storage
• Often required to maintain warranty coverage

Q: What size circuit breaker do I need?

A: The PET-19 requires a 16A circuit breaker minimum on a dedicated circuit. Your electrician should also install:

• 30mA RCD (Residual Current Device) protection
• Appropriate cable sizing based on cable run length
• Weatherproof outdoor isolator switch
• Proper earthing/grounding

Always consult a qualified electrician to ensure compliance with BS 7671 wiring regulations.

Maintenance & Longevity

Q: How much maintenance does it need?

A: The PET-19 is designed for minimal maintenance. Required tasks:

Monthly:

• Check water flow and filter pressure
• Clean air filter if debris present
• Inspect for any unusual noises or leaks

Annually:

• Professional service inspection (recommended)
• Check refrigerant levels (by qualified technician)
• Clean evaporator fins if dusty/dirty
• Test all safety switches and sensors
• Inspect electrical connections

Winter (if not in use):

• Drain heat pump completely
• Install winter cover
• Disconnect power supply

With proper maintenance, expect 12-15 years lifespan.

Q: Is it noisy?

A: No—the PET-19 is remarkably quiet thanks to Full Inverter Technology:

• Silent Mode: 40dB (whisper-quiet, library level)
• Smart Mode: 45-50dB (quiet conversation level)
• Boost Mode: 54dB (normal conversation level)

For comparison: a dishwasher is typically 50dB, a normal conversation is 60dB. Neighbors won’t even notice it’s running in Silent Mode.

Q: What about the warranty?

A: Warranty terms vary by supplier. Typically includes:

• 2 years parts and labor (standard manufacturer warranty)
• Extended warranties may be available from retailer
• Coverage for defects in materials and workmanship
• Excludes damage from improper installation, lack of maintenance, or freeze damage

Always register your product and keep proof of professional installation to validate warranty.

Smart Features & Controls

Q: Can I control it from my phone?

A: Yes, with the optional iQBridge RS module (sold separately), you can:

• Control the heat pump remotely via the iAquaLink®+ app
• Set heating schedules and timers
• Monitor real-time temperature and performance
• Receive alerts and notifications
• Adjust modes (Boost/Smart/Silent) from anywhere
• Track energy consumption
• Integrate with Fluidra Connect smart pool ecosystem

The unit includes a 10m Modbus signal wire for easy connection to the iQBridge RS.

Q: What is the heating priority mode?

A: This intelligent feature automatically controls your pool’s filtration pump based on heating demand:

• When the heat pump needs to heat water, it can automatically turn on the filtration pump
• Ensures water circulation whenever heating is active
• Prevents dry running and optimizes heat transfer
• Saves energy by coordinating pump operation with heating cycles
• No manual intervention required

Comparison & Selection

Q: How does this compare to gas or electric heating?
