🏊 Pool Heating Capacity
- Heat Output Range: 50 kW – 354 kW (depending on supply temperature and flow rate)
- Suitable for Pools Up To: 320,000 litres / 70,000 gallons
- Boiler Systems: Rated for up to 350 kW boiler capacity
- Renewable Energy Systems: Optimised for up to 150 kW (heat pumps/solar collectors)
⚡ Efficiency Factors
Achieving optimal heat transfer performance depends on:
- Maintaining adequate hot water flow rate (50-160 l/min recommended range)
- Pool water flow at or near maximum capacity (650 l/min)
- Temperature differential between heat source and pool water
- Proper heat exchanger sizing for your specific application
ℹ️ Important: As the manufacturer data demonstrates, heat transfer performance varies significantly with flow rate and temperature. Undersized flow rates will result in reduced heat transfer efficiency.
⏱️ Heat-Up Times & Temperature Maintenance
⚠️ Important Notice: Heat-up times vary significantly based on multiple factors and cannot be accurately predicted without knowing your specific installation parameters.
Variables That Affect Heating Time:
- Heat source capacity (kW/BTU rating of your boiler, heat pump, or solar system)
- Starting water temperature
- Target water temperature (typical pool: 26-28°C)
- Pool cover usage (reduces heat loss by up to 75%)
- Ambient/outdoor temperature and weather conditions
- Pool insulation and construction
- Heat exchanger flow rate optimisation
ℹ️ Why We Don’t Publish Generic Heat-Up Times:
Heat exchangers are passive devices – they transfer heat from your primary heat source (boiler, heat pump, or solar collectors) to your pool water. The actual heating speed is determined primarily by your heat source’s output capacity, not the heat exchanger itself.
For example, this heat exchanger can transfer up to 354 kW when supplied with 82°C water at 160 l/min flow – but your actual performance depends entirely on what your heat source can deliver.

🔨 Installation Considerations
Mounting Options
The FG160-5115-5T-SP can be installed in either vertical or horizontal orientation, providing flexibility for various plant room configurations.
- Mounting brackets included as standard
- Mounting hole centres: 642mm and 746mm
- Mounting hole diameter: Ø7mm
Connection Requirements
| Connection | Size | Purpose |
|---|---|---|
| Pool Water Inlet/Outlet | 2½” BSP | Tube side (pool circuit) |
| Hot Water Inlet/Outlet | 1¼” BSP | Shell side (heat source circuit) |
Flow Direction
Correct flow direction is essential for optimal performance. The heat exchanger operates on a counter-flow principle:
- Pool Water: Flows through the tube side
- Hot Water: Flows through the shell side in the opposite direction
Key Installation Points
✅ Install isolation valves on both circuits for maintenance access
✅ Fit a non-return valve on the heat source circuit
✅ Position any automatic dosing systems AFTER the heat exchanger on the return to pool
✅ Ensure adequate flow rates on both circuits (refer to performance tables)
✅ Utilise the built-in thermostat pocket (Ø7 x 52mm) for temperature monitoring
⚠️ Professional Installation Recommended: We strongly recommend installation by a qualified heating engineer or pool installation professional to ensure optimal performance and warranty compliance.
