💰 Usage Costs & Running Expenses

📊 Annual Running Cost Calculation

Understanding the true cost of operation helps you budget effectively and compare options. Here’s the realistic cost breakdown for the HPS151M:

Power Consumption: 1.1 kW
Typical Swimming Season: 6 months (May-October)
Daily Operation: 8 hours per day
Annual Operating Hours: 8 hours × 180 days = 1,440 hours
Current UK Electricity Rate: £0.2635 per kWh (Q4 2025)

✅ HPS151M Annual Running Cost:
1.1 kW × 1,440 hours × £0.2635 = £417.19 per year

💡 Cost Comparison Scenarios

🏊 Scenario 1: Upgrading from a 1HP Pump

Many homeowners operate older 1HP pumps that may be less efficient:

❌ Older 1HP Pump (0.90kW equivalent power draw):
0.90 kW × 1,440 hours × £0.2635 = £341.42 per year

✅ HPS151M (1.1kW with higher efficiency):
£417.19 per year

Additional Annual Cost: £75.77

However, consider these benefits:

• ⚡ 50% more flow capacity improves filtration effectiveness
• 💧 Reduced chemical usage due to better water circulation
• 🔄 Fewer pump running hours needed to achieve same water quality
• 🛡️ Superior build quality reduces repair and replacement costs
• 📈 Better property value with professional-grade equipment

🌊 Scenario 2: Extended Season Swimming with Solar Heating

For pools with solar heating extending the season to 8 months:

Extended Operation: 8 hours × 240 days = 1,920 hours
✅ Annual Cost: 1.1 kW × 1,920 hours × £0.2635 = £556.26 per year

Monthly Breakdown: £69.53 per month during swimming season

⏱ Scenario 3: Optimal Run Time Strategy

Running the pump during off-peak hours with a timer can optimize costs:

Reduced Daily Hours: 6 hours per day × 180 days = 1,080 hours
✅ Annual Cost: 1.1 kW × 1,080 hours × £0.2635 = £312.89 per year

💰 Savings vs 8-hour operation: £104.30 per year

Note: Ensure 6-hour operation provides adequate turnover for your pool volume

💷 Scenario 4: Variable Speed vs Single Speed Comparison

While the HPS151M is a single-speed pump, it’s worth comparing to variable speed alternatives:

Variable Speed Pump (average 0.45kW):
0.45 kW × 1,440 hours × £0.2635 = £170.82 per year

HPS151M Single Speed:
£417.19 per year

Difference: £246.37 per year

BUT consider:

• 💵 Variable speed pumps cost £800-1,200 (vs £400-500 for HPS151M)
• ⏳ Payback period: 3-4 years before savings realized
• 🔧 Higher repair costs and electronic complexity
• ✅ HPS151M simplicity means fewer potential failures

For seasonal pools with moderate run times, the HPS151M offers better value through reliability and lower upfront investment.

🎯 Real World Applications & Examples

🏊 Medium to Large Residential Pools (40-60m³)

The HPS151M is perfectly sized for family pools in this range. A typical 12m × 4m × 1.5m average depth pool (72m³) requires complete water turnover every 6-8 hours for optimal filtration.

Performance: At 18.7 m³/h (typical operating point with 6m head), the HPS151M circulates 150m³ in 8 hours – sufficient for pools up to 60m³ with proper filtration. For larger pools, the pump ensures at least 1.5 turnovers per day, exceeding minimum standards and maintaining crystal-clear water.

Installation Context: Commonly installed with sand filters (24-30″ diameter) or cartridge filter systems rated for residential applications.

🌊 Pool Upgrades & Retrofits

Homeowners upgrading from undersized or failing pumps benefit significantly from the HPS151M’s robust construction and reliable performance.

Typical Upgrade Path: Replacing 0.75HP or 1HP pumps that struggle to maintain water clarity or require frequent repairs. The HPS151M’s additional power ensures effective filtration even as systems age and flow resistance increases.

Installation Benefits: Standard 1.5″ connections match existing pipework, quick-connect unions simplify installation, and self-priming capability accommodates various pump locations.

♨️ Solar Heated Pool Systems

Solar pool heating systems require pumps that can handle extended seasonal operation and maintain consistent flow through solar panels.

Solar Panel Compatibility: The HPS151M provides sufficient head pressure to circulate water through roof-mounted solar panel arrays (typically 3-6m additional head), while maintaining adequate flow rate for effective heat transfer.

Extended Season Economics: While operating costs increase with longer seasons, solar heating eliminates gas/electric heating costs (saving £800-1,500 annually), making the pump’s energy consumption negligible by comparison.

🏡 New Pool Construction Projects

For new installations, the HPS151M represents the “right-sized” solution for most residential applications, providing headroom for future additions without over-engineering the system.

Contractor Favorite: Easy to source, straightforward installation, reliable warranty support, and proven performance make this a preferred specification for pool builders.

Future-Proofing: 1.5HP capacity accommodates future additions like water features, in-floor cleaning systems, or supplementary filtration without system redesign.

🔄 Salt Chlorination System Compatibility

Modern salt chlorinated pools require pumps with corrosion-resistant components to handle the more aggressive water chemistry.

HPS151M Advantages: Stainless steel shaft, composite body, and Noryl impeller all resist salt water degradation. The pump maintains performance and reliability in salt pool environments where standard pumps fail prematurely.

System Integration: Works seamlessly with all major salt chlorinator brands, maintaining the consistent flow required for effective chlorine generation.

🌡️ Indoor Pool Installations

Indoor pools present unique challenges with high humidity and elevated ambient temperatures that can damage standard motors.

IP-55 Protection: The fully enclosed motor resists moisture ingress and operates reliably in humid environments. Class F insulation handles elevated temperatures without derating.

Maintenance Environment: One-piece body design and minimal seal points reduce leak risk in finished indoor pool rooms where water damage is particularly costly.
