🏊 Pool Heating Performance
- Maximum Heat Output: 354 kW (at 82°C hot water, 160 l/min flow)
- Suitable for pools up to: 320m³ / 70,000 gallons
- Heat Source Compatibility: Boilers (up to 350kW), Heat Pumps, Solar Thermal Systems (up to 150kW)
⚡ Efficiency Factors
Optimal heat transfer depends on maintaining correct flow rates on both circuits. According to Bowman’s technical documentation, insufficient flow on either the hot water or pool water side will prevent the heat exchanger from performing at designed efficiency. Ensure your system meets the following requirements:
- Pool water flow: Up to 650 l/min maximum
- Hot water flow: Match to your heat source output (50-160 l/min typical range)
- Temperature differential: Higher differential = greater heat transfer
⏱️ Heat-Up Times & Temperature Maintenance
⚠️ Heat-up times vary based on multiple factors including:
- Heat source output (boiler/heat pump kW rating)
- Starting water temperature
- Desired temperature rise
- Pool insulation and cover usage
- Ambient/outdoor temperature conditions
- Heat exchanger sizing match to pool volume
The FG160-5115-5T is a passive heat transfer device – actual heating times depend entirely on your primary heat source capacity and installation conditions.
💡 Performance Guidance
The manufacturer states the FG160-5115-5T can handle:
- Boiler heating systems: Up to 350kW input
- Renewable energy systems: Up to 150kW input (heat pumps, solar thermal)
🛡️ Material & Compatibility Guide
Why Choose Titanium?

Flow Direction
Correct flow direction is essential for optimal performance. The unit is clearly marked:
- Pool Water Inlet → Pool Water Outlet (through tube side)
- Boiler Water Inlet → Boiler Water Outlet (through shell side)
Installation Best Practices
✅ Install isolation valves on all connections for maintenance access
✅ Fit a non-return valve on the pool water return circuit
✅ Position dosing systems AFTER the heat exchanger on the return to pool
✅ Ensure adequate flow rates on both circuits – low flow significantly reduces heat transfer efficiency
✅ Allow minimum clearance for end cover removal during maintenance
⚠️ Professional installation is strongly recommended to ensure warranty compliance and optimal system performance.
