💰 Usage Costs & Running Expenses

📊 Annual Running Cost Calculation

Understanding the true operational costs of your pool pump is essential for budget planning and evaluating the financial benefits of upgrading to modern three-phase technology. Here’s a comprehensive breakdown:

AQUA203 Three-Phase Pump:

• Power consumption: 1.5kW (2HP)
• Typical commercial usage: 10 hours/day × 300 days/year = 3,000 hours annually
• UK commercial electricity rate: £0.26 per kWh (Q4 2025 average for non-domestic users)
• ✅ Annual running cost: 1.5kW × 3,000 hours × £0.26 = £1,170

💸 Cost Comparison vs Single-Phase Alternative

Comparing AQUA203 (Three-Phase) against equivalent 2HP Single-Phase pump:

❌ Old Single-Phase 2HP Pump:

• Power consumption: 1.85kW (typical single-phase 2HP motor, less efficient)
• Same usage: 10 hours/day × 300 days = 3,000 hours
• Energy cost: 1.85kW × 3,000 × £0.26 = £1,443 annually

✅ AQUA203 Three-Phase:

• Energy cost: £1,170 annually (as calculated above)

💷 Annual Saving: £273 per year ⏱ 5-Year Saving: £1,365 📈 10-Year Saving: £2,730

⚡ Three-Phase Efficiency Advantage

Three-phase motors inherently offer superior efficiency compared to single-phase motors of equivalent horsepower. The AQUA203’s three-phase design provides:

• 15-20% better energy efficiency through more balanced power distribution
• Lower operating temperatures resulting in extended motor lifespan
• Reduced maintenance requirements due to smoother operation
• Better starting torque with lower inrush current
