⚡ Efficiency Factors

• Optimal Performance – Achieved with hot water flow rates of 40-60 l/min
• Reduced Performance – Flow rates below 20 l/min significantly reduce heat transfer efficiency
• Pool Circulation – Maintain 250 l/min pool water flow for rated performance
• Temperature Differential – Greater difference between heat source and pool water temperatures improves transfer rates

⏱️ Heat-Up Times & Temperature Maintenance

⚠️ Important: Heat-up times vary significantly based on multiple factors and are not specified in manufacturer documentation for this model. Variables that affect heating time include:

• Heat source capacity (kW/BTU rating of your boiler, heat pump, or solar array)
• Starting water temperature
• Target water temperature
• Pool cover usage and quality
• Ambient/outdoor temperature
• Pool insulation
• Weather conditions and wind exposure
• Heat exchanger sizing match to heat source

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

• Pool Water Outlet: Top connection (when horizontal)
• Hot Water: Counter-flow recommended for optimal heat transfer

Installation Notes

⚠️ If an automatic chemical dosing system is fitted, it must be installed after the heat exchanger on the return to the pool.

⚠️ Isolation valves should be fitted on both primary (hot water) and secondary (pool water) circuits.

⚠️ A non-return valve is recommended on the hot water circuit.

Space Requirements

• Overall Length: 768mm
• Shell Diameter: 86mm
• Mounting Hole Centres: 452mm
