💰 Usage Costs & Running Expenses

Understanding the true cost of pool pump ownership requires accurate calculation of annual running expenses. The Badu Top S25’s E-Plus motor technology delivers significant efficiency advantages over conventional pumps.

📊 Annual Running Cost Calculation

Power Consumption: 1.70kW (P1 – actual electricity draw)
UK Electricity Rate: £0.2635 per kWh (Ofgem Price Cap, Q4 2025)

🏊 Scenario 1: Seasonal Residential Pool (6 Months Operation)

Typical UK outdoor pool running during summer months:

• Daily Operation: 8 hours/day
• Season Length: 180 days (April–September)
• Annual Hours: 8 × 180 = 1,440 hours

Calculation:
1.70kW × 1,440 hours × £0.2635 = £645.05 per year

💰 Monthly Cost (during season): £107.51

♨️ Scenario 2: Year-Round Heated Pool

Indoor or heated outdoor pool requiring continuous circulation:

• Daily Operation: 10 hours/day
• Annual Days: 365 days
• Annual Hours: 10 × 365 = 3,650 hours

Calculation:
1.70kW × 3,650 hours × £0.2635 = £1,635.23 per year

💰 Monthly Cost: £136.27

🏢 Scenario 3: Extended Commercial Operation

Larger residential or light commercial use:

• Daily Operation: 12 hours/day
• Annual Days: 365 days
• Annual Hours: 12 × 365 = 4,380 hours

Calculation:
1.70kW × 4,380 hours × £0.2635 = £1,962.28 per year

💰 Monthly Cost: £163.52

🎯 Real World Examples & Applications

🏊‍♂️ Medium to Large Residential Pools

The Badu Top S25’s 1.30kW output is perfectly matched to pools between 50,000 and 100,000 litres. With flow rates up to 28,636 L/hr, it can turn over a 75,000-litre pool approximately every 2.5 hours—ideal for maintaining crystal-clear water quality.

🌊 Saltwater Pool Systems

Designed specifically to handle salt chlorinator systems with concentrations up to 0.5% (5g/L), the S25’s corrosion-resistant materials ensure years of trouble-free operation. The carbon/ceramic mechanical seal and reinforced plastic components resist salt degradation far better than standard pumps.

🔄 Upgrading from Older Single-Phase Pumps

If you’re replacing an ageing pump that’s becoming unreliable or consuming excessive power, the S25 offers a direct replacement with modern efficiency. The standard 2″/1½” connections and flexible union adapters (metric and imperial included) ensure compatibility with most existing pipework.

🏠 Above-Ground Pool Installations

The 3-metre self-priming capability makes the S25 excellent for above-ground pools where the pump must be positioned away from or above the water level. No foot valve is strictly required, though one is recommended for faster repriming after maintenance.

🛁 Wellness & Hydrotherapy Systems

The quiet operation (≤70dB) and high flow capacity make this pump suitable for spa hydrotherapy systems and wellness centres where noise levels and water turnover are critical considerations.

☀️ Solar Heating Circuits

Sufficient head pressure (17m max) to push water through roof-mounted solar heating panels while maintaining adequate flow for effective heat transfer.

💡 Cost Savings Examples

📍 Scenario: Upgrading from an Old 1.5kW Single-Speed Pump

Many older pool pumps draw significantly more power for equivalent output. A typical 15-year-old 1.5kW pump may have degraded efficiency, actually drawing closer to 2.0kW at the wall.

Old Pump Running Costs (estimated):

• Power Draw: 2.0kW (degraded efficiency)
• Usage: 8 hours/day × 180 days = 1,440 hours
• ❌ Annual Cost: 2.0 × 1,440 × £0.2635 = £758.88

Speck Badu Top S25 Running Costs:

• Power Draw: 1.70kW
• Usage: 1,440 hours
• ✅ Annual Cost: 1.70 × 1,440 × £0.2635 = £645.05

💵 Annual Saving: £113.83
📈 5-Year Saving: £569.15

📍 Scenario: Replacing a Failed 0.75kW Pump with Undersized Performance

Pool owners sometimes install undersized pumps that run longer to achieve adequate filtration, actually costing more than a properly-sized unit.

Undersized 0.75kW Pump (running extended hours):

• Power Draw: 0.90kW (at wall)
• Usage: 14 hours/day × 180 days = 2,520 hours (to compensate)
• ❌ Annual Cost: 0.90 × 2,520 × £0.2635 = £597.56
• ❌ Plus: Inadequate filtration, cloudy water, additional chemical costs

Correctly-Sized Speck Badu Top S25:

• Power Draw: 1.70kW
• Usage: 8 hours/day × 180 days = 1,440 hours (adequate turnover)
• ✅ Annual Cost: 1.70 × 1,440 × £0.2635 = £645.05

💰 Additional Cost: Only £47.49 more annually
✅ Benefits: Proper filtration, clearer water, reduced chemical usage, longer equipment life

📍 Scenario: Comparing Against Budget Pumps with Higher Running Costs

Budget pumps often have lower purchase prices but inferior motor efficiency, costing significantly more over their lifetime.

Budget 1.3kW Pump (poor motor efficiency):

• Actual Power Draw: 1.95kW (at wall)
• Usage: 1,440 hours (seasonal)
• ❌ Annual Cost: 1.95 × 1,440 × £0.2635 = £740.09

Speck Badu Top S25 (E-Plus Motor):

• Power Draw: 1.70kW
• Usage: 1,440 hours
• ✅ Annual Cost: £645.05

💵 Annual Saving: £95.04
📈 Over 10-Year Pump Lifespan: £950.40 saved
⏱ Payback on Premium Purchase: Typically 2-3 years through energy savings alone
