• Usage: 8 hours/day × 180 days = 1,440 hours/year
• Annual consumption: 0.57 kW × 1,440 hours = 820.8 kWh
• ✅ Annual cost: £216.28

Extended Season Usage (8 months):

• Usage: 8 hours/day × 240 days = 1,920 hours/year
• Annual consumption: 0.57 kW × 1,920 hours = 1,094.4 kWh
• ✅ Annual cost: £288.37

Year-Round Heated Pool (12 months):

• Usage: 8 hours/day × 365 days = 2,920 hours/year
• Annual consumption: 0.57 kW × 2,920 hours = 1,664.4 kWh
• ✅ Annual cost: £438.54

💵 Cost Comparison vs. Higher Power Models

Compared to a typical older 0.75HP single-phase pump drawing 0.65kW:

6-Month Season:

• ❌ Old 0.75HP pump annual cost: £246.46
• ✅ Supastream WRSS051 annual cost: £216.28
• 💰 Annual saving: £30.18

12-Month Year-Round:

• ❌ Old 0.75HP pump annual cost: £499.99
• ✅ Supastream WRSS051 annual cost: £438.54

⚡ Energy Efficiency Advantage: The Supastream’s optimized hydraulic design means you get adequate flow for smaller to medium pools while consuming approximately 12% less electricity than comparable 0.75HP models.

🎯 Real World Examples & Applications

🏊‍♂️ Small to Medium Residential Pools (20,000-40,000 litres)

Perfect for typical family pools measuring 4m × 8m or smaller. The 14.4 m³/hr flow rate provides complete pool turnover in 3-6 hours, meeting recommended filtration standards for residential pools. Ideal for pools with sand or cartridge filters up to 500mm diameter.

🛁 Garden Hot Tubs & Swim Spas

Excellent for recirculating water in smaller commercial or residential hot tubs and swim spas where continuous low-pressure circulation is required. The secondary seal protection makes this pump particularly suitable for heated water applications up to 45°C.

🌊 Ornamental Ponds & Water Features

Suitable for large garden ponds and decorative water features requiring gentle recirculation. The 50mm connections handle adequate flow for pond filtration systems while the corrosion-resistant construction withstands outdoor environments and varied water chemistry.

🏠 Pool Equipment Upgrades

Ideal replacement for ageing or inefficient pumps on existing smaller pools. The quick-connect unions and standard 50mm plumbing connections make retrofitting straightforward, often achieving better hydraulic efficiency than older pump designs while reducing electricity consumption.

☀️ Seasonal Pool Installations

Well-suited for seasonal pools used primarily during warmer months (May-September). The efficient design keeps running costs manageable during the swimming season, while drain plugs and compact size simplify winterization and storage during off-season months.

💡 Cost Savings Examples

📍 Scenario 1: Replacing a 15-Year-Old 0.75HP Pump

Many older single-phase pumps from the 2010s consumed significantly more electricity due to less efficient motor and hydraulic designs.

Old pump consumption: 0.75 kW New Supastream WRSS051: 0.57 kW Usage: 8 hours/day, 180 days/year (standard UK pool season)

Annual Costs:

• ❌ Old pump: 0.75 kW × 1,440 hours × £0.2635 = £284.58
• ✅ New Supastream: 0.57 kW × 1,440 hours × £0.2635 = £216.28
• 💰 Annual saving: £68.30
• ⏱ Payback period: Approximately 3-4 years (assuming £250-£300 pump cost)
• 📈 5-year saving: £341.50

📍 Scenario 2: Comparing Against Budget Unbranded Pumps

Generic 0.6HP pumps may have lower upfront costs but typically lack efficiency features and robust construction.

Budget pump consumption: 0.65 kW (typical for non-optimized designs) Supastream WRSS051: 0.57 kW Usage: 8 hours/day, 240 days/year (extended season)

Annual Costs:

• ❌ Budget pump: 0.65 kW × 1,920 hours × £0.2635 = £328.99
• ✅ Supastream: 0.57 kW × 1,920 hours × £0.2635 = £288.37
• 💰 Annual saving: £40.62
• 📊 Plus: Genuine Waterco components, 316 stainless steel seal, secondary seal protection, and UK manufacturer support
• 📈 5-year total saving: £203.10 (while enjoying superior reliability)

📍 Scenario 3: Protection Against Rising Energy Prices

UK electricity prices have increased significantly since 2021. With prices expected to remain elevated:

Current rate: £0.2635/kWh (Q4 2025) Projected rate: £0.30/kWh (conservative estimate for 2026-2027)

Future Annual Cost (6-month season):

• Higher-power 0.75HP pump: 0.75 kW × 1,440 hours × £0.30 = £324.00
• ✅ Efficient Supastream: 0.57 kW × 1,440 hours × £0.30 = £246.24
• 💰 Future annual saving: £77.76

💷 Energy Efficiency Protection: Every kWh you don’t consume is money saved, regardless of future price increases. The Supastream’s efficient design provides built-in protection against rising energy costs.
