💰 Usage Costs & Running Expenses
📊 Annual Running Cost Calculation
Understanding your pump’s operating costs helps you budget effectively and make informed decisions about run times and energy efficiency.
Power Consumption: 0.74 kW
Typical Usage: 8 hours/day × 150 days (May-September swimming season)
Annual Operating Hours: 1,200 hours
Current UK Electricity Rate: £0.2635 per kWh (Ofgem cap, October-December 2025)
✅ Annual Running Cost:
- Calculation: 0.74 kW × 1,200 hours × £0.2635/kWh = £234 per swimming season
- Monthly cost during operation: £234 ÷ 5 months = £46.80 per month
- Daily cost: £234 ÷ 150 days = £1.56 per day
🏊 Extended Season Operation (8 months, heated pool)
For year-round or heated pools with extended seasonal operation:
Extended Usage: 8 hours/day × 240 days
Annual Operating Hours: 1,920 hours
✅ Extended Season Cost:
- Calculation: 0.74 kW × 1,920 hours × £0.2635/kWh = £374 per year
- Monthly average: £46.75 per month
⚡ Energy Efficiency Comparison
Compared to older, less efficient 1HP pumps (typically 0.85-0.95kW):
❌ Older 0.90kW pump running 1,200 hours:
- 0.90 kW × 1,200 hours × £0.2635/kWh = £284 per season
✅ HGS101SM running 1,200 hours:
- 0.74 kW × 1,200 hours × £0.2635/kWh = £234 per season
💷 Annual Saving: £50 per swimming season
📈 Three-Year Saving: £150
The HGS101SM’s efficient motor design typically delivers 15-20% energy savings compared to older single-phase pool pumps of equivalent horsepower, with the actual savings varying based on your specific installation and run times.
💡 Cost-Saving Tips
⏱ Optimize Run Times: Running your pump during off-peak hours (if you have an Economy 7 tariff at approximately £0.20/kWh) can reduce daily costs by about 25%, saving approximately £60 annually.
☀ Seasonal Adjustment: During cooler months when pool usage is reduced, cutting run time from 8 to 6 hours daily saves approximately £12 per month while still maintaining adequate filtration.
🔄 Regular Maintenance: Keeping the strainer basket clean and ensuring good water flow reduces motor strain and can improve efficiency by 5-10%, potentially saving £12-24 annually.
🎯 Real World Examples & Applications
🏠 Medium-Sized Residential Pools (25-35m³)
Typical Installation: Garden swimming pool, 8m × 4m × 1.4m average depth (approximately 30m³ water volume)
Application Details: The HGS101SM provides complete water turnover every 2-3 hours when operating at typical head pressures (6-8m), meeting the recommended filtration standards for residential pools. The 1HP motor handles moderate head pressures from sand filters or cartridge filtration systems without strain.
Expected Performance: At 8m head (typical for residential sand filter installations), expect approximately 15 m³/hr flow rate, providing two complete pool turnovers in an 8-hour operating day. This exceeds the recommended single turnover per day for residential pools, ensuring excellent water clarity.
🛁 Hot Tub Integration & Spa Pools
Typical Installation: Domestic spa pools or hot tubs requiring dedicated circulation pump (separate from jet pumps)
Application Details: While marketed primarily for swimming pools, the HGS101SM works effectively as a circulation pump for larger spa installations where continuous low-flow circulation maintains water quality between therapy sessions. The salt-compatible construction makes it ideal for saltwater spa systems.
Expected Performance: Provides gentle, continuous circulation without the noise and energy consumption of high-powered jet pumps. The 1HP rating offers sufficient flow for filtration while remaining economical for extended run times.
🔄 Upgrade & Replacement Scenarios
Typical Installation: Replacing older, failing pool pumps in existing residential installations
Application Details: The HGS101SM’s standard 1.5″ connections and compact footprint make it an excellent drop-in replacement for aged pool pumps. Homeowners upgrading from 15-20 year old equipment typically see immediate improvements in reliability, noise levels, and energy consumption.
Expected Performance: Modern hydraulic efficiency typically delivers equivalent or better flow rates than older pumps while consuming 15-25% less energy. The improved self-priming capability often solves chronic air lock issues common with aging pump installations.
🏊♀ Seasonal Pools & Holiday Homes
Typical Installation: Weekend homes or seasonal properties with domestic pools requiring reliable, unattended operation
Application Details: The HGS101SM’s robust motor protection (IP55) and reliable self-priming make it suitable for installations where the pump may need to operate with minimal supervision. The continuous duty rating ensures the motor handles extended run times during summer months.
Expected Performance: Reliable start-up after periods of inactivity, with the self-priming design minimizing concerns about maintaining prime during occasional use. The translucent strainer basket allows quick visual inspection during weekend visits.
🌊 Water Features & Pond Circulation
Typical Installation: Large decorative water features or koi ponds requiring constant circulation (up to 35m³)
Application Details: When fitted with appropriate pre-filtration, the HGS101SM can serve water feature applications requiring moderate head pressure and continuous circulation. The salt-compatible materials suit applications with water conditioning systems.
Expected Performance: Provides consistent flow for maintaining water quality in decorative applications. The continuous duty motor rating supports 24/7 operation when required, though energy costs should be considered for always-on applications.
💡 Cost Savings Examples
📍 Scenario 1: Replacing a 15-Year-Old Pool Pump
Old Pump Specifications: Generic 1HP pump, 0.92kW power consumption, frequent starting issues
Operating Pattern: 8 hours/day, 150 days per season
Old Annual Cost: 0.92 kW × 1,200 hours × £0.2635/kWh = £290.80
✅ New HGS101SM Annual Cost: 0.74 kW × 1,200 hours × £0.2635/kWh = £234.00
💰 Annual Saving: £56.80
⏱ Three-Year Saving: £170.40
📈 Five-Year Saving: £284.00
Additional benefits: Improved reliability eliminates service call costs (typically £85-150 per visit), while better self-priming reduces time spent manually bleeding air from the system.
📍 Scenario 2: Optimizing Operating Schedule
Current Operation: Running pump continuously during daytime hours (8am-4pm) at standard rate electricity
Improved Operation: Shifting to split operation (3 hours morning + 5 hours evening off-peak)
❌ Standard Rate Cost (8 hours): 0.74 kW × 8 hours × 150 days × £0.2635/kWh = £234
✅ Mixed Rate Cost (3 hours standard + 5 hours off-peak at £0.20/kWh):
- Standard rate: 0.74 kW × 3 hours × 150 days × £0.2635/kWh = £87.80
- Off-peak rate: 0.74 kW × 5 hours × 150 days × £0.20/kWh = £111.00
- Total: £198.80
💸 Annual Saving: £35.20
📊 Reduction: 15% lower operating cost
Note: This strategy works best if you have an Economy 7 or similar time-of-use electricity tariff. Actual savings vary based on your specific electricity pricing structure.
📍 Scenario 3: Seasonal vs. Year-Round Pool Heating
Understanding the cost difference between seasonal and extended operation helps plan pool heating decisions:
☀ Seasonal Operation (May-September): 150 days × 8 hours = 1,200 hours
Cost: £234 per year
🔥 Extended Season (April-October with heating): 210 days × 8 hours = 1,680 hours
Cost: 0.74 kW × 1,680 hours × £0.2635/kWh = £328
💵 Additional Cost for Extended Season: £94
💷 Year-Round Heated Pool (All Year): 365 days × 8 hours = 2,920 hours
Cost: 0.74 kW × 2,920 hours × £0.2635/kWh = £569
💰 Additional Cost for Year-Round Operation: £335 over seasonal-only operation
This analysis demonstrates the pump circulation represents a relatively modest portion of heated pool operating costs (typically 10-15% of total energy costs when including heating). The HGS101SM’s efficiency helps minimize this unavoidable expense.
