💰 Usage Costs & Running Expenses
📊 Annual Running Cost Calculation
Understanding your pump’s running costs helps you budget effectively and make informed decisions about operation schedules:
Power Consumption: 1.1 kW (1.09 kW input power from technical data)
Typical Domestic Pool Usage Scenario:
- Operating hours: 6 hours per day during swimming season (May-September = 153 days)
- Annual operating hours: 918 hours
- UK domestic electricity rate: 25.73p per kWh (Ofgem price cap, Q3 2025)
✅ Annual Running Cost:
- 1.09 kW × 918 hours × £0.2573 = £257.60 per year
- Monthly cost during season: £51.52
- Daily cost: £1.68
🏊 Different Usage Scenarios
Scenario 1: Standard Domestic Pool (6 hours daily, 5 months)
- Annual hours: 918 hours
- ✅ Annual cost: £257.60
Scenario 2: Extended Season Pool (8 hours daily, 6 months)
- Annual hours: 1,464 hours
- ✅ Annual cost: £411.44
Scenario 3: Hot Tub Application (4 hours daily, year-round)
- Annual hours: 1,460 hours
- ✅ Annual cost: £410.00
Scenario 4: Heated Pool (12 hours daily, 7 months)
- Annual hours: 2,556 hours
- ✅ Annual cost: £717.80
💷 Energy Price Considerations
Energy costs are calculated using current UK domestic electricity rates. The Ofgem price cap for Q3 2025 (July-September) sets the average rate at 25.73p per kWh for households on standard variable tariffs paying by direct debit. Your actual costs may vary slightly depending on:
- Your specific regional pricing (UK has 14 distribution zones with slight variations)
- Your payment method (direct debit is typically cheapest)
- Your energy tariff (fixed vs. variable rates)
- Time-of-use tariffs (if you run during off-peak hours)
💡 Energy Saving Tip: Consider using a timer to run your pump during off-peak hours if you have an Economy 7 or Economy 10 tariff, potentially reducing costs by 40-50%.
🎯 Real World Examples & Applications
🏊♂️ Domestic Swimming Pools
The Supastream 1.5HP is perfectly sized for residential swimming pools between 30m³ and 60m³ (approximately 6,600 to 13,200 gallons). Common UK residential pool sizes of 8m × 4m × 1.4m average depth (approximately 45m³) can be effectively circulated 3-4 times daily, ensuring excellent water clarity and chemical distribution. Homeowners appreciate the reliable performance during the busy summer months, with enough power to handle pool vacuuming and automatic cleaning systems simultaneously.
🛁 Hot Tubs & Spas
For larger hot tubs and spa installations, this pump provides the circulation needed for effective heating and filtration. The 1.5HP rating delivers sufficient flow for most 6-8 person hot tubs, working efficiently with modern filtration systems and heating elements. The thermal overload protection is particularly valuable in hot tub applications where water temperatures approach the pump’s upper operating range.
🌊 Water Features & Garden Ponds
Decorative ponds and water features benefit from the Supastream’s reliable circulation and easy maintenance. The large strainer basket is particularly useful in pond applications where leaves and organic matter are constant challenges. The quiet operation (59-65 dBA) makes it suitable for residential gardens without creating noise disturbance.
🔄 Pool Upgrade & Replacement Projects
Many homeowners choose the Supastream 1.5HP when replacing aging pool pumps from the 1990s and early 2000s. Modern hydraulic efficiency means this pump often replaces older 2HP units while providing equal or better performance with reduced energy consumption. The standard 50mm connections ensure compatibility with most existing UK pool plumbing systems.
☀️ Seasonal Pool Operations
UK pool owners particularly value the drain plugs that enable complete winterization. At the end of the swimming season, the pump can be fully drained to protect against freeze damage, then easily recommissioned in spring. The quick-connect unions make seasonal removal and storage straightforward for those who prefer to store their pump indoors during winter months.
