📊 Heat Transfer Performance

The FC100-5114-2C delivers substantial heating capacity, with output varying based on your heat source temperature:

🏊 Pool Heating Capacity:

Heat Source Temperature	Heat Output
82°C (Standard Boiler)	100 kW / 340,000 BTU/hr
60°C (Condensing Boiler/Heat Pump)	55 kW / 190,000 BTU/hr

Performance figures based on achieving 30°C pool water temperature

⚡ Efficiency Factors:

• Flow rate optimisation – maintain recommended 90 L/min primary and 350 L/min secondary flow rates
• Temperature differential – greater difference between heat source and pool water improves efficiency
• Proper sizing – ensure heat source capacity matches heat exchanger rating
• Counter-flow installation – essential for maximum performance

⏱️ 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
• Target water temperature
• Pool cover usage and insulation
• Ambient/outdoor temperature
• Weather conditions and heat losses

The Bowman FC100-5114-2C can transfer up to 100kW of heat energy when properly matched with an adequate heat source. Actual heating duration depends entirely on your specific installation configuration.

ℹ️ Note: Heat exchangers are passive devices that transfer heat from your boiler or heat pump to pool water. The heating time is determined by your heat source capacity, not the heat exchanger alone. For accurate calculations tailored to your installation, please contact our technical team.

🛡️ Material & Compatibility Guide

The FC100-5114-2C features a Cupro-Nickel tubestack, providing excellent performance for standard pool applications:

Cupro-Nickel Benefits

✅ Standard chlorinated freshwater pools
✅ Excellent heat transfer properties
✅ Good corrosion resistance for conventional pool chemicals
✅ Cost-effective for standard installations
✅ Proven durability in thousands of installations worldwide

Important Compatibility Notes

❌ Not suitable for salt water chlorinators
❌ Not suitable for salt water pools

For salt water applications, the Titanium variant (FC100-5114-2T) is required.

Recommended Water Chemistry Limits (from Bowman documentation):

Parameter	Cupro-Nickel Limit
Free Chlorine	1.0 – 3.0 ppm
pH	7.2 – 7.8
Calcium Hardness	200 – 400 ppm

🔨 Installation Considerations

Mounting Options:

• Horizontal or vertical mounting permitted
• Install in frost-free, dry location with non-aggressive atmosphere
• Ensure adequate access for maintenance and tubestack removal

Connection Requirements:

• Primary (boiler) side: 1″ BSP threaded connections
• Secondary (pool) side: Solvent weld for Ø60.3mm (2″ imperial) or Ø63mm (DN50 metric) pipe
• Adaptors included to accommodate both imperial and metric pipework

Critical Installation Points:

• Counter-flow installation essential – pool water must flow opposite to heating water direction
• Install downstream of filtration equipment
• Chemical dosing systems must be fitted downstream of heat exchanger with non-return valve
• Use isolation valves on all connections for maintenance access
• Heating circuit should be pump-assisted with air lock prevention measures
• Install thermostat in pool water pipe before heat exchanger for temperature control

Operating Limits:

• Maximum pressure: 6 bar on both circuits
• Maximum heating water temperature: 110°C
• Maximum pool water temperature: 100°C
• Do not exceed 350 L/min pool water flow rate

⚠️ Professional installation is recommended for warranty compliance and optimal performance. Installation must comply with the Bowman Installation, Operation & Maintenance Guide.
