• Daily cost: 2.08 kWh × £0.2635 = £0.55
• Annual cost: £0.55 × 180 days = £98.82

❌ Traditional Single-Speed Pump (1.5 kW):

• Power consumption: 1.5 kW (constant)
• Daily usage: 1.5 kW × 8 hours = 12 kWh
• Daily cost: 12 kWh × £0.2635 = £3.16
• Annual cost: £3.16 × 180 days = £568.80

💷 Annual Savings: £469.98

🎯 Real World Applications

🏊‍♂️ Residential Swimming Pools (40-70m³)

The InverPro 25 VS is perfectly sized for medium to large domestic pools. Its intelligent Auto-Inverter mode maintains consistent water flow while automatically adjusting motor speed to compensate for filter loading, ensuring crystal-clear water with minimal energy expenditure. The whisper-quiet operation means you can run filtration during evening gatherings or early mornings without disturbing neighbours.

Typical Installation: Private garden pool with sand or cartridge filtration, standard 63mm pipework, and optional salt chlorination system.

🛁 Spa & Hot Tub Circulation

With water temperature tolerance up to 50°C and precise flow control from 5-25 m³/h, the InverPro 25 provides ideal circulation for commercial spa installations or large domestic hot tubs. The variable speed allows gentle, continuous circulation that maintains water quality while minimising chemical usage and evaporation.

Typical Installation: Wellness centre spa pool, hotel hydrotherapy facility, or luxury residential spa with water feature integration.

🌊 Water Features & Fountains

The programmable timer function enables different flow rates throughout the day – gentle circulation overnight, increased flow for fountain displays during business hours, and maximum capacity for special events. External control via RS485 Modbus allows integration with landscape lighting and building automation systems.

Typical Installation: Hotel entrance fountain, commercial water feature, or residential pond with waterfall.

🔄 Pump Replacement & Upgrades

The InverPro 25’s standard 2″ union connections and flexible fitting options (48.5/50/60.3/63mm) make it an ideal replacement for aging single-speed pumps. Most installations can be completed with minimal pipework modification, delivering immediate energy savings from day one.

Typical Installation: Replacement of 10+ year old single-speed pump, upgrade from basic two-speed model, or conversion to variable speed for automation compatibility.

🏢 Small Commercial Facilities

Holiday parks, boutique hotels, and private health clubs with pools in the 40-70m³ range benefit from the InverPro 25’s commercial-grade reliability combined with residential-friendly single-phase power requirements. The comprehensive protection systems and diagnostic error codes simplify maintenance and minimise downtime.

Typical Installation: Holiday cottage pool, small hotel pool, private fitness club, or residential care facility.

💡 Cost Savings Examples

📍 Scenario 1: Replacing an Aging Single-Speed Pump

Situation: Your 15-year-old single-speed pump (1.5 kW) is becoming noisy and less efficient. Running 8 hours daily for a 180-day season.

Factor	❌ Old Single-Speed	✅ InverPro 25 VS
Power Consumption	1.5 kW constant	0.26 kW average
Annual Energy Use	2,160 kWh	374 kWh
Annual Running Cost	£568.80	£98.82
Annual Savings	—	💵 £469.98

⏱️ Investment Payback: With annual savings approaching £470, the InverPro 25 typically pays for itself within 2-3 seasons through reduced electricity bills alone – not counting the improved reliability and reduced maintenance costs.

📍 Scenario 2: High-Usage Commercial Environment

Situation: Small hotel pool (60m³) operating 12 hours daily, 365 days per year.

Calculation Basis:

• Energy rate: £0.2635/kWh
• Daily operation: 12 hours
• InverPro 25 average capacity: 60% (0.38 kW)

Factor	❌ Single-Speed 1.8kW	✅ InverPro 25 VS
Daily Energy	21.6 kWh	4.56 kWh
Daily Cost	£5.69	£1.20
Annual Cost	£2,076.85	£438.00
Annual Savings	—	💷 £1,638.85

📈 5-Year Savings: Over a typical commercial equipment lifecycle, the InverPro 25 would save approximately £8,194 compared to operating a traditional single-speed pump.

📍 Scenario 3: Extended Season with Pool Heating

Situation: Heated pool running 10 hours daily for 280 days (March-November).

Factor	❌ Single-Speed 1.5kW	✅ InverPro 25 VS
Daily Energy	15 kWh	2.6 kWh
Season Energy	4,200 kWh	728 kWh
Season Cost	£1,106.70	£191.83
Annual Savings	—	💰 £914.87

💡 Additional Benefit: The InverPro 25’s reduced heat generation compared to single-speed pumps means less energy lost through pump room heat dissipation – providing marginal but measurable savings on pool heating costs.

📊 Long-Term Value Summary

Timeframe	Savings vs Single-Speed (Standard Season)	Savings vs Single-Speed (Year-Round)
Year 1	£469.98	£953.56
Year 3	£1,409.94	£2,860.68
