💡 Cost Savings Examples

📍 Scenario 1: Replacing an Oversized 15HP Pump

Many commercial pools operate with oversized pumps that waste energy running at partial capacity.

❌ Old 15HP Pump (11kW) – 12 hours/day:

• Annual consumption: 11 kW × 4,380 hours × £0.24 = £11,566

✅ Right-Sized MC1003 (7.5kW) – Same performance:

• Annual consumption: 7.5 kW × 4,380 hours × £0.24 = £7,884

💰 Annual Savings: £3,682
📈 3-Year Savings: £11,046
⏱ Pump pays for itself through energy savings in under 2 years

---

📍 Scenario 2: Upgrading from Old Low-Efficiency Technology

Older pumps from the 1990s-2000s typically operate at 65-70% efficiency compared to modern 80-87% efficient motors.

❌ Old 10HP Standard Efficiency Pump (70% efficient):

• Actual power draw: ~10.7 kW
• Annual cost (8 hours/day, 240 days): 10.7 × 1,920 × £0.24 = £4,930

✅ MC1003 High-Efficiency Pump (85% efficient):

• Actual power draw: 7.5 kW
• Annual cost (same operation): 7.5 × 1,920 × £0.24 = £3,456

💰 Annual Savings: £1,474
💵 5-Year Savings: £7,370

---

📍 Scenario 3: Commercial Pool Annual Operating Cost Reduction

Hotel Pool – 150m³ capacity, 12 hours/day operation

❌ Using Multiple Smaller Residential Pumps:

• 2× 5HP pumps running 12 hours = 7.5 kW × 2 × 4,380 hours × £0.24 = £15,768/year
• Frequent maintenance, shorter lifespan, higher failure risk

✅ Single MC1003 Commercial Pump:

• 1× 10HP industrial pump = 7.5 kW × 4,380 hours × £0.24 = £7,884/year
• Reduced maintenance, extended lifespan, single-point control

💰 Annual Savings: £7,884
📊 Plus: Reduced maintenance costs, fewer spare parts, simplified control systems
