🏊 Scenario 1: Energy-Efficient Low-Speed Operation (Routine Circulation)

Running at optimal efficiency (approximately 35% capacity for daily maintenance):

• Power consumption: ~0.35 kW
• Daily usage: 8 hours
• Annual hours: 8 × 180 = 1,440 hours
• ✅ Annual cost: 0.35 kW × 1,440 hours × £0.26 = £131.04

🏊 Scenario 2: Medium-Speed Operation (Standard Filtration)

Running at 60% capacity for pools requiring higher turnover:

• Power consumption: ~0.85 kW
• Daily usage: 8 hours
• Annual hours: 1,440 hours
• ✅ Annual cost: 0.85 kW × 1,440 hours × £0.26 = £318.24

🏊 Scenario 3: High-Performance Operation (Heavy Use/Commercial)

Running at 85% capacity for demanding applications:

• Power consumption: ~1.4 kW
• Daily usage: 8 hours
• Annual hours: 1,440 hours
• ✅ Annual cost: 1.4 kW × 1,440 hours × £0.26 = £524.16

🏊 Scenario 4: Maximum Performance (Full Power)

Running at full 1.8kW capacity:

• Power consumption: 1.8 kW
• Daily usage: 8 hours
• Annual hours: 1,440 hours
• ✅ Annual cost: 1.8 kW × 1,440 hours × £0.26 = £673.92

💷 Comparison with Traditional Single-Speed Pumps

🎯 Real World Examples & Applications

🏊‍♂ Large Residential Swimming Pools (70-100m³)

The Inverpro 40 VS is the ideal choice for substantial domestic pools where powerful circulation is essential. The ability to run at lower speeds during quiet periods whilst having full power available for parties or intensive use provides the perfect balance of efficiency and performance. The whisper-quiet operation ensures poolside entertaining remains undisturbed.

🏢 Commercial Pool Facilities

Hotels, leisure centres, health clubs, and holiday parks benefit enormously from the Inverpro 40 VS. The Auto-Inverter mode maintains consistent water turnover even as filters load up during busy periods, whilst the RS485 Modbus connectivity enables seamless integration with building management systems. The 4-timer programming allows different flow rates during peak and off-peak hours.

🛁 Large Spa & Wellness Installations

Hydrotherapy pools, wellness centres, and commercial spas requiring high flow rates and reliable operation find the Inverpro 40 VS perfectly suited. The pump operates with water temperatures up to 50°C, and the soft-start protection safeguards connected heating and treatment equipment.

🌊 Water Features & Commercial Fountains

Large ornamental features, commercial water displays, and architectural fountains benefit from the precise flow control between the pump’s full operating range. The timer function enables scheduled operation during business hours whilst conserving energy overnight.

☀ Solar Heating Systems

The Auto-Inverter mode excels when pumping water to rooftop solar collectors. The system automatically compensates for the additional head pressure, maintaining consistent flow regardless of the height differential. This ensures optimal heat transfer and system efficiency.

🔄 Pump Replacement & System Upgrades

Upgrading from an older single-speed pump delivers immediate and substantial energy savings. The standard 63mm pipe compatibility and flexible union sizing (48.5-63mm) ensures straightforward installation in most existing systems. The 2-metre suction height capability accommodates various plant room configurations.
