💰 Usage Costs & Running Expenses

📊 Annual Running Cost Calculation

Understanding the true operating cost of your pump is essential for budgeting and comparing equipment options. Here’s a detailed breakdown:

EUP151 Power Consumption:

• Motor power: 1.1 kW (1,100 watts)
• Actual running power: Approximately 1.1-1.2 kW under typical operating conditions

🏊 Typical Hot Tub Scenario:

• Usage: 8 hours per day (includes filtration cycles and usage time)
• Operating days: 365 days per year
• Annual hours: 2,920 hours
• UK commercial electricity rate: £0.26 per kWh (Nov 2025 average)

✅ Annual Running Cost: 1.1 kW × 2,920 hours × £0.26/kWh = £834 per year

Daily cost: £834 ÷ 365 = £2.29 per day

💡 Cost Comparison: Upgrading from Older Technology

If you’re considering replacing an aging or less efficient pump, the energy savings can be substantial:

❌ Older 1.5HP pump (typical efficiency):

• Power consumption: 1.4 kW (older motors run less efficiently)
• Annual cost: 1.4 kW × 2,920 hours × £0.26/kWh = £1,062 per year

✅ Certikin EUP151 (modern efficiency):

• Annual cost: £834 per year

💵 Annual Savings: £228 per year

⏱️ 3-Year Savings: £684 – Substantial savings that offset a significant portion of the pump replacement cost

🌊 Commercial Pool Application Costs

For smaller commercial pools or larger residential pools requiring extended filtration:

Intensive Usage Scenario:

• Operating hours: 12 hours per day (6am-6pm)
• Operating days: 365 days per year
• Annual hours: 4,380 hours
• Commercial electricity rate: £0.28 per kWh

Annual Operating Cost: 1.1 kW × 4,380 hours × £0.28/kWh = £1,348 per year

Monthly cost: £1,348 ÷ 12 = £112 per month

⚡ Energy Efficiency vs. Budget Alternatives

Comparing against a budget 1.5HP pump:

❌ Budget pump characteristics:

• Lower efficiency motor
• Higher power draw: ~1.5 kW
• Annual cost (8hr/day): 1.5 kW × 2,920 hrs × £0.26/kWh = £1,140

✅ Certikin EUP151:

• Annual cost (8hr/day): £834

💰 Annual Saving: £306 📈 5-Year Saving: £1,530 – The quality investment pays for itself multiple times over
