💰 Usage Costs & Running Expenses

One of the most compelling reasons to choose the Inverter Pump Silence 1.5HP is its exceptional energy efficiency. Here’s a detailed breakdown of what you can expect to pay for pool circulation:

📊 Annual Running Cost Calculation

Assumptions:

• UK Electricity Rate: £0.2635 per kWh (Q4 2025 Ofgem price cap)
• Swimming Season: 180 days (April – September)
• Extended Season with Heating: 270 days (March – November)

🏊 Scenario 1: Standard Residential Pool (50m³)

Running 8 hours daily at 50% capacity for efficient filtration:

Factor	Calculation
Power consumption at 50%	0.35 kW
Daily hours	8 hours
Daily energy use	0.35 × 8 = 2.8 kWh
Daily cost	2.8 × £0.2635 = £0.74
Seasonal cost (180 days)	£133.20
Extended season (270 days)	£199.80

♨ Scenario 2: Heated Pool with Extended Filtration

Running 12 hours daily at 60% capacity:

Factor	Calculation
Power consumption at 60%	0.45 kW
Daily hours	12 hours
Daily energy use	0.45 × 12 = 5.4 kWh
Daily cost	5.4 × £0.2635 = £1.42
Seasonal cost (180 days)	£255.60
Extended season (270 days)	£383.40

🌊 Scenario 3: Maximum Performance Mode

Running 6 hours daily at 100% capacity for larger pools:

Factor	Calculation
Power consumption at 100%	1.2 kW
Daily hours	6 hours
Daily energy use	1.2 × 6 = 7.2 kWh
Daily cost	7.2 × £0.2635 = £1.90
Seasonal cost (180 days)	£342.00

📈 Comparison: Inverter vs Single-Speed Pump

Traditional single-speed 1.5HP pumps typically consume 2.0-2.5 kW continuously, regardless of actual filtration needs. Here’s how the costs compare:

❌ Traditional Single-Speed 1.5HP Pump

Factor	Calculation
Power consumption	2.2 kW (typical)
Daily hours	8 hours
Daily energy use	2.2 × 8 = 17.6 kWh
Daily cost	17.6 × £0.2635 = £4.64
Seasonal cost (180 days)	£835.20

✅ Inverter Pump Silence at 50% Capacity

Factor	Calculation
Power consumption	0.35 kW
Daily hours	8 hours
Daily energy use	0.35 × 8 = 2.8 kWh
Daily cost	2.8 × £0.2635 = £0.74
Seasonal cost (180 days)	£133.20

💷 Annual Savings: £702.00

⚡ That’s an 84% reduction in energy costs!

🎯 Real World Examples & Applications

🏠 Residential Pool Upgrade

Perfect for: Homeowners with pools between 40-70m³ seeking quiet operation and reduced running costs

A typical 50m³ garden pool requires one complete water turnover every 4-6 hours. The Inverter Pump Silence can achieve this running at just 50-60% capacity, consuming only 0.35-0.45 kW instead of the 2.2 kW a single-speed pump would require. Neighbours will appreciate the near-silent operation, especially during evening filtration cycles.

🏢 Holiday Let & Rental Properties

Perfect for: Property owners who want reliable, cost-effective pool maintenance

With app-based monitoring, you can check pump status and adjust settings remotely between guest stays. The four built-in timers allow precise scheduling around changeover days, and the ultra-quiet operation won’t disturb guests enjoying poolside relaxation.

🔄 Single-Speed Pump Replacement

Perfect for: Anyone looking to upgrade from a noisy, inefficient traditional pump

Direct replacement is straightforward with standard 2″ connections. The immediate benefits include dramatically reduced noise levels (from 65+ dB(A) to under 33 dB(A)) and energy savings of up to 90%. Most installations see payback on the investment within 2-3 seasons through electricity savings alone.

♨ Heated Pool Systems

Perfect for: Pools with heat pumps requiring extended circulation periods

When paired with an inverter heat pump, this circulation pump enables 24/7 low-speed operation for optimal heating efficiency. Running at 30-40% capacity around the clock uses approximately the same energy as 4-5 hours of single-speed operation, while maintaining perfect water temperature distribution.

🌊 Water Features & Spillovers

Perfect for: Pools with integrated fountains, waterfalls, or infinity edges

The 120% boost mode provides extra flow for dramatic water features when entertaining, while standard filtration runs quietly at reduced capacity. The variable flow rate also allows you to adjust the look and sound of water features to suit the occasion.
