💡 Cost Savings Examples

📍 Scenario: Replacing a Worn Commercial Pump

Ageing pumps lose efficiency significantly – worn bearings, degraded seals, and tired motors can increase power consumption by 20-30%. Replacing a failing pump restores optimal performance.

Factor	Old Worn Pump	New Vipool MJB
Estimated power draw	~2.40 kW (degraded)	1.84 kW
Annual energy (3,600 hrs)	8,640 kWh	6,624 kWh
❌ Old annual cost	£2,246.40	—
✅ New annual cost	—	£1,722.24
💰 Annual savings	—	£524.16

📈 5-Year Projection: £2,620.80 in energy savings, plus avoided emergency repair costs, reduced downtime, and improved reliability.

📍 Scenario: Upgrading from Single-Phase to Three-Phase

If your facility has three-phase supply available, switching from a single-phase pump to the three-phase equivalent improves efficiency and reduces long-term maintenance costs.

Factor	2.5HP Single-Phase	2.5HP Three-Phase
Power consumption	2.10 kW	1.84 kW
Motor stress	Higher (unbalanced load)	Lower (balanced)
Expected lifespan	8-10 years	12-15 years
Annual energy (3,600 hrs)	7,560 kWh	6,624 kWh
❌ Single-phase annual cost	£1,965.60	—
✅ Three-phase annual cost	—	£1,722.24
💰 Annual savings	—	£243.36

📍 Scenario: Right-Sizing from Oversized 3HP Pump

Commercial installers sometimes specify oversized pumps “for safety margin.” If your facility only requires 30m³/hr, an oversized 3HP pump wastes energy without benefit.

Factor	Oversized 3HP Pump	Right-Sized 2.5HP
Power consumption	2.20 kW	1.84 kW
Flow rate delivered	30 m³/hr	30 m³/hr ✅
Annual energy (3,600 hrs)	7,920 kWh	6,624 kWh
❌ Oversized annual cost	£2,059.20	—
✅ Right-sized annual cost	—	£1,722.24
💰 Annual savings	—	£336.96

📍 Scenario: Commercial Facility – 10-Year Total Cost Analysis

For commercial operators, total cost of ownership over equipment lifecycle matters more than initial purchase price.

Cost Element	Budget Commercial Pumps	Vipool MJB Three-Phase
Initial purchase	£650	£850
Replacements (10 years)	£1,300 (2 × £650)	£0 (one pump)
Energy (10 years × £2,060)	£20,600	—
Energy (10 years × £1,722)	—	£17,220
Maintenance/call-outs	~£1,500 (3 failures)	~£400 (routine only)
Downtime costs	~£2,000 (lost revenue)	~£0
