📊 Heat Transfer Performance
The FC100-5114-2C delivers impressive heat transfer capabilities, with performance directly linked to both the hot water supply temperature and flow rates through the unit.
🏊 Pool Heating Performance:
- Heat Output: Up to 100 kW (340,000 BTU/hr)
- Suitable for pools up to: 170,000 litres (37,000 gallons)
- Designed for: Boiler heat source applications
⚡ Heat Transfer at Various Temperatures:
Based on pool water flow of 350 l/min at 28°C (manufacturer data):
| Hot Water Temp | Flow 30 l/min | Flow 60 l/min | Flow 100 l/min |
|---|---|---|---|
| 82°C | 56 kW | 79 kW | 98 kW |
| 70°C | 43 kW | 61 kW | 75 kW |
| 60°C | 32 kW | 45 kW | 56 kW |
| 45°C | 17 kW | 23 kW | 29 kW |
💡 Efficiency Factors:
- Optimal performance requires adequate flow rates on both circuits
- Higher hot water temperatures increase heat transfer capacity
- Pool water flow rate of 350 l/min recommended for maximum efficiency
- Proper sizing of heat source (boiler) is essential for optimal results
⏱️ Heat-Up Times & Temperature Maintenance
⚠️ Important Notice: Heat-up times vary significantly based on multiple factors including:
- Heat source output (boiler kW rating)
- Starting water temperature
- Target water temperature
- Pool cover usage and quality
- Ambient/outdoor temperature conditions
- Weather and wind exposure
- Pool insulation characteristics
The FC100-5114-2C is a passive heat transfer device – actual heating times depend entirely on your heat source capacity and installation conditions.
💧 Flow Rate Importance:
As stated in the manufacturer documentation: “Providing the right water flow volume is vital to the performance of the heat exchanger. If the flow rate of either the hot water supply, or the pool water circuit is too low, the heat exchanger will not perform at its designed efficiency and will be unable to transfer all the available heat energy into the pool water.”
ℹ️ Note: For specific pool heating calculations based on your boiler size, pool volume, and desired temperature rise, professional assessment is recommended
