📊 Heat Transfer Performance

The Bowman HEB5114-5 delivers variable heat output depending on your heat source temperature:

🏊 Pool Heating Performance

Heat Source Temperature	Heat Output	Suitable Pool Volume
70°C (Heat Pump/Solar)	130 kW / 444,000 BTU/hr	Up to 200,000 litres
60°C (Heat Pump/Solar)	96 kW / 325,000 BTU/hr	Up to 180,000 litres
45°C (Low Temp Source)	47 kW / 160,000 BTU/hr	Up to 94,000 litres

Performance data based on achieving a pool water temperature of 30°C

⚡ Efficiency Factors

The actual heat transfer achieved depends on several key factors:

• Heat source output – Your boiler or heat pump kW rating determines available energy
• Flow rate optimisation – Maintaining recommended flow rates ensures peak performance
• Temperature differential – Greater difference between heat source and pool water increases transfer rate
• Proper sizing – Matching heat exchanger capacity to pool volume and heat source
• Counter-flow installation – Essential for maximum efficiency (pool water flows opposite to heating water)

⏱️ Heat-Up Times & Temperature Maintenance

⚠️ Important Notice: Heat-up times vary significantly based on multiple installation-specific factors including:

• Heat source output (boiler/heat pump kW rating)
• Starting water temperature vs target temperature
• Ambient/outdoor temperature conditions
• Pool cover usage and insulation quality
• Heat exchanger sizing match to system
• Weather conditions and heat losses

General Guidance

The HEB5114-5 is rated for pools up to 200,000 litres when paired with an appropriately sized heat source. As a passive heat transfer device, the heat exchanger transfers heat from your boiler or heat pump to the pool water – actual heating times depend on your heat source capacity.

ℹ️ Note: Heat exchangers do not generate heat; they transfer it. Your heating times are ultimately determined by your boiler or heat pump output, not the heat exchanger rating alone.

🛡️ Material & Compatibility Guide

Choose the right tube stack material for your water chemistry:

Titanium (T Suffix)

✅ Salt water pools and salt chlorinators
✅ Chlorinated pools of any type
✅ Maximum corrosion resistance – immune to all known pool chemicals
✅ Highest flow rates and heat transfer capability
✅ 10-year guarantee on all titanium in contact with pool water
✅ Ultimate “fit and forget” solution
❌ Higher initial cost (offset by longevity)

Cupro-Nickel (C Suffix)

✅ Chlorinated freshwater pools
✅ Excellent heat transfer properties
✅ Good corrosion resistance for standard pool chemicals
✅ Cost-effective durability
❌ Not suitable for salt water or salt chlorinators

Stainless Steel (S Suffix)

✅ Freshwater applications only
✅ Standard chlorinated pools
✅ Most economical option
❌ Must NOT be used with salt water chlorinators or salt water pools

🌊 Water Parks – Theme park attractions and water leisure facilities

☀️ Solar Thermal Integration – Connect to solar panel arrays for renewable pool heating

🔥 Boiler Systems – Commercial gas, oil, or biomass boiler connections

⚡ Heat Pump Systems – Air source or ground source heat pump integration

🔨 Installation Considerations

Mounting Options

The HEB5114-5 can be mounted either horizontally or vertically to suit your plant room configuration.

Connection Requirements

• Pool water connections: Solvent weld for Ø60.3mm (2″ NPS) or Ø63mm (DN50) pipe
• Heat source connections: 1″ BSP threaded fittings
• 38mm pipe insertion depth into end covers

Critical Installation Points

⚠️ Counter-flow installation is mandatory – Pool water must flow in the opposite direction to heating water for optimal heat transfer. Failure to install correctly will significantly reduce performance.

⚠️ Thermostat positioning – Install the thermostat in the integral pocket on the pool water inlet side for accurate temperature monitoring.

⚠️ Chemical dosing systems – Must be fitted downstream from the heat exchanger with a non-return valve to prevent chemical damage.

⚠️ Flow rates – Do not exceed the maximum pool water flow rate of 380 l/min (23 m³/h).

⚠️ Frost protection – Install in a frost-free enclosure. Drain completely or remove if premises are exposed to frost during winter shutdown.

Professional Installation Recommended

For warranty compliance and optimal performance, we strongly recommend professional installation by a qualified plumber or pool heating engineer.
