💰 Usage Costs & Running Expenses

Understanding the true cost of pool pump operation is essential for commercial facilities. The Magnus-4 300’s efficient 2.2kW motor delivers significant savings compared to older or less efficient alternatives.

📊 Annual Running Cost Calculation

Power Consumption: 2.2kW

UK Commercial Electricity Rate: £0.27 per kWh (November 2025 average for business users)

🏊 Scenario 1: Seasonal Commercial Pool (6 Months Operation)

• Operating hours: 10 hours/day × 180 days = 1,800 hours/year
• Energy consumption: 2.2kW × 1,800 hours = 3,960 kWh/year
• ✅ Annual running cost: 3,960 × £0.27 = £1,069.20

🏢 Scenario 2: Year-Round Hotel/Leisure Facility

• Operating hours: 12 hours/day × 365 days = 4,380 hours/year
• Energy consumption: 2.2kW × 4,380 hours = 9,636 kWh/year
• ✅ Annual running cost: 9,636 × £0.27 = £2,601.72

♨ Scenario 3: Spa/Wellness Centre (Extended Hours)

• Operating hours: 16 hours/day × 365 days = 5,840 hours/year
• Energy consumption: 2.2kW × 5,840 hours = 12,848 kWh/year
• ✅ Annual running cost: 12,848 × £0.27 = £3,468.96

⚡ Three-Phase Efficiency Advantage

Three-phase motors like the Magnus-4 300 typically offer 10-15% greater efficiency compared to single-phase equivalents due to smoother power delivery and reduced starting currents. This translates directly into lower electricity bills and reduced strain on electrical infrastructure.

• ❌ Annual cost: £2,700

Magnus-4 300 Three-Phase:

• Consumption: 2.2kW × 4,000h = 8,800 kWh
• ✅ Annual cost: £2,376

💵 Annual Saving: £324 📈 10-Year Saving: £3,240

📍 Scenario: Municipal Pool Lifecycle Cost

A council-operated swimming pool running 12 hours daily, 6 days per week, 50 weeks per year:

• Operating hours: 12 × 6 × 50 = 3,600 hours/year
• Magnus-4 300 consumption: 2.2kW × 3,600h = 7,920 kWh
• ✅ Annual electricity cost: 7,920 × £0.27 = £2,138.40

Compared to 3.5kW alternative:

• Consumption: 3.5kW × 3,600h = 12,600 kWh
• ❌ Annual cost: £3,402

💷 Annual Saving: £1,263.60 📈 Over typical 10-year pump lifespan: £12,636 saved
