💰 Usage Costs & Performance Impact
📊 Performance Restoration Benefits
Replacing a worn impeller can dramatically improve your pump system’s efficiency and reduce operating costs. A degraded impeller forces your motor to work harder to achieve the same flow rates, increasing energy consumption and accelerating wear on other pump components.
⚡ Energy Efficiency Considerations
Impact of Impeller Condition on Energy Consumption:
A typical 5.50hp pump motor draws approximately 4.1kW of power. When the impeller degrades through wear, cavitation damage, or chemical erosion, the pump must run longer to circulate the same volume of water, directly impacting your electricity costs.
💸 Worn Impeller – Extended Runtime Scenario:
- Motor power: 4.1kW
- Effective flow reduced by 25% due to wear
- Required extended runtime: 33% longer to achieve same circulation
- Daily operation: 8 hours becomes 10.6 hours
- ❌ Annual cost (10.6 hrs/day × 180 days × £0.24/kWh): £1,829
- Excess cost due to wear: £457 annually
✅ New Impeller – Optimal Performance:
- Motor power: 4.1kW
- Full design flow capacity restored
- Standard operation: 8 hours daily
- Running season: 180 days per year
- Energy rate: £0.24 per kWh (UK average, 2024)
- Annual cost: 4.1kW × 8 hrs × 180 days × £0.24 = £1,372
💷 Annual Savings from Impeller Replacement: £457
Note: Actual savings depend on specific operating conditions, water chemistry, existing impeller condition, and filtration cycle requirements. This calculation demonstrates typical commercial pool operational patterns.
🏊 Commercial Pool Application Example
Scenario: 150,000-litre commercial pool requiring 3 complete turnovers daily
📍 With Degraded Impeller (20% flow reduction):
- Required extended operation to achieve turnover targets
- ❌ Increased energy consumption: ~£450 annually
- ❌ Accelerated motor bearing wear
- ❌ Inconsistent water quality from inadequate circulation
- ❌ Potential code compliance issues
✅ With New Genuine Calpeda Impeller:
- Optimal flow rates restore proper turnover times
- 💰 Energy savings: £450+ annually
- ⏱ Faster return to optimal operation
- 📈 Extended pump system lifespan
- ✅ Reliable code-compliant circulation
🎯 Real World Examples & Applications
🏊♂ Large Residential Swimming Pools
High-capacity residential pools (75,000-150,000 litres) benefit from the robust performance of the 5.50hp impeller. Homeowners with substantial pool installations require reliable, efficient circulation to maintain water quality across large volumes. This impeller provides the flow rates necessary for proper filtration turnover, effective chemical distribution, and consistent heating performance.
🏢 Light Commercial Pool Facilities
Hotels, health clubs, and community facilities with mid-sized pools rely on 5.50hp pumps for dependable daily operation. The commercial-grade construction withstands continuous-duty cycles while maintaining efficiency. Regular impeller replacement as part of preventive maintenance schedules minimizes unexpected downtime during peak operational periods.
🌊 Water Feature & Fountain Systems
Large decorative water features requiring substantial flow rates and pressure benefit from the 5.50hp impeller’s robust performance characteristics. The corrosion-resistant construction handles continuous operation in outdoor environments with varying water quality conditions.
🔄 Pump System Refurbishment Projects
When upgrading or refurbishing existing pool systems, replacing the impeller alongside other wear components ensures the entire pump assembly operates at peak efficiency. This comprehensive approach maximizes the return on maintenance investment and extends overall system life.
♨ Heated Pool Circulation
Heated pools, particularly those with heat pumps or solar heating, require consistent flow rates to maintain temperature. A worn impeller compromises heat transfer efficiency, forcing heating systems to work harder. The new impeller restores proper circulation for optimal heat distribution.
💡 Cost Savings Examples
📍 Scenario 1: Preventive Replacement vs. Emergency Failure
❌ Emergency Replacement Approach:
- Impeller fails catastrophically during peak season
- Emergency callout: £200-300
- Lost facility usage: 2-3 days
- Rush shipping: £50-75
- Total impact: £250-375 + operational disruption
✅ Planned Preventive Replacement:
- Scheduled during off-season maintenance
- Standard installation during routine service
- No emergency premiums or lost revenue
- Total cost: Component only + scheduled labour
- 💰 Savings: £250-375 + avoided disruption
⏱ Payback Period: Immediate through avoiding emergency costs
📍 Scenario 2: Energy Efficiency Recovery
Comparing a moderately worn impeller (15% performance loss) to a new replacement over a 3-year operational period:
❌ Continuing with Worn Impeller:
- Extended runtime to maintain circulation: ~15% longer
- Annual excess energy cost: £275
- 3-year cumulative excess cost: £825
- Accelerated motor wear from increased runtime
- Potential premature motor replacement: £800-1,200
✅ New Impeller Installation:
- Component cost: ~£720 (one-time)
- Restored efficiency eliminates excess runtime
- 3-year energy savings: £825
- 💵 Net benefit over 3 years: £105 + extended motor life
- 📈 Long-term value: £900-1,300 when including avoided motor replacement
📍 Scenario 3: Commercial Facility Operational Efficiency
Application: Medium commercial pool (120,000 litres) operating 300 days annually
❌ Operating with Degraded Impeller (25% capacity loss):
- Extended daily runtime: 10.5 hours vs. optimal 8 hours
- Annual energy consumption: 4.1kW × 10.5 hrs × 300 days = 12,915 kWh
- Annual cost at £0.24/kWh: £3,100
- Water quality issues from inadequate circulation
- Potential health code violations
✅ After New Impeller Installation:
- Optimal runtime restored: 8 hours daily
- Annual energy consumption: 4.1kW × 8 hrs × 300 days = 9,840 kWh
- Annual cost: £2,362
- 💷 Annual savings: £738
- ⏱ Component payback period: ~11 months
- 📊 5-year savings: £3,690 – component cost = ~£2,970 net benefit
These calculations use UK average commercial electricity rates. Actual savings vary based on local energy costs, water chemistry, operational patterns, and existing component condition.
