💪 Waterco Supastream 1.50HP Single Phase Pool Pump
Maximum Single-Phase Power for Large Pools & Demanding Applications 🚀
📋 Product Overview
The Waterco Supastream 1.50HP is the flagship of the single-phase Supastream range, delivering an exceptional 20,100 litres per hour at 8 metres head. This commanding flow rate makes it the ultimate choice for large residential pools, high-usage family installations, and applications where maximum single-phase circulation power is required.
Engineered for those who refuse to compromise on performance, the Supastream 150 harnesses Waterco’s advanced hydraulic design to achieve remarkable efficiency.

The Supastream 1.50HP delivers nearly triple the flow of the 0.50HP model while using less than double the electricity – outstanding efficiency at the top of the range.
📊 Annual Running Cost Calculation
Power consumption: 1.09 kW
Current UK electricity rate: £0.2635 per kWh (Ofgem Price Cap, Q4 2025)
🏊 Scenario 1: Seasonal Large Pool (6 Months)
Standard UK outdoor operation for a substantial pool during swimming season:
- Daily run time: 8 hours
- Season length: 180 days (6 months)
- Annual operating hours: 8 × 180 = 1,440 hours
💵 Annual Running Cost:
1.09 kW × 1,440 hours × £0.2635 = £413.49 per year
That’s approximately £68.92 per month during the swimming season.
♨️ Scenario 2: Year-Round Large Heated Pool
For indoor pools or heated outdoor installations requiring continuous high-capacity circulation:
- Daily run time: 10 hours
- Operating days: 365 days
- Annual operating hours: 10 × 365 = 3,650 hours
💵 Annual Running Cost:
1.09 kW × 3,650 hours × £0.2635 = £1,048.28 per year
That’s approximately £87.36 per month for year-round operation.
🏠 Scenario 3: Premium Residential with Extended Season
For luxury homes with pool heating extending the usable season:
- Daily run time: 8 hours
- Operating days: 240 days (April–November)
- Annual operating hours: 8 × 240 = 1,920 hours
💵 Annual Running Cost:
1.09 kW × 1,920 hours × £0.2635 = £551.32 per year
